Description

The invention relates to and a method for determining movement patterns in a dental treatment, in particular tooth cleaning, to a coupling element for coupling to a toothbrush and to an electric toothbrush.

Due to the relatively long intervals of up to several months or even years between the individual visits to the dentist, the problem arises that the instructions of the dentist regarding frequency, duration and type of treatment are easily forgotten or, over time, movements that are not optimal are incorporated , whereby the oral hygiene is not optimally guaranteed or damage to the oral cavity, in particular firm and / or soft mouth components, such as teeth, jaw and / or gums.

The publication EP 1 379 149 B1 discloses a method for monitoring the position of a toothbrush in relation to a person's teeth, the method comprising: providing a toothbrush with a first position sensor, the first position sensor being at least sensitive to changes in position and orientation, providing a second position sensor in a fixed positional relationship to the teeth, the second position sensor being sensitive to changes in position and orientation; Transmitting the output of the first position sensor and the second position sensor to the processing device, and the processing device compares the two sensor outputs to monitor the position of the toothbrush with respect to the teeth over a period of time.

This system is disadvantageous because complex sensors have to be attached to a face in a defined manner, which makes the system expensive and complex, which makes high market acceptance difficult. Yu-Chen Chang et. al. describe in the article "Playful Toothbrush: UbiComp Technology for Teaching Tooth Brushing to Kindergarten Children" a system in which the movement of the toothbrush is optically recorded. This system is disadvantageous because the movements recorded are undefined in space, whereby movement of the head causes the recorded data to be falsified. Furthermore, complex modifications of the toothbrush are assumed, which makes the system complex and expensive and thus also appears inaccessible to a mass market. In addition, the system must be installed in a fixed position so that a camera can recognize the modified toothbrush in a defined manner.

Furthermore, both systems are based on predefined data sets, which means that it is not possible to improve knowledge about toothbrush movements.

The pamphlets WO2017042673A1 . WO2014202250A1 . WO2016180929A1 disclose electric toothbrushes according to which movements that occur when brushing teeth are to be recorded.

The pamphlets EP3238565A1 . WO2017029469A1 . WO2018046723 disclose adapters for coupling to toothbrushes.

The subjects of the PCT patent applications / EP2014 / 062077 WO2016 / 016323 also show very advantageous solutions for detecting movement profiles when brushing teeth. Nevertheless, these solutions require powerful terminals, since a complex position detection is determined from a sensor fusion from the data of an optical detection device and a non-optical sensor device.

It is therefore an object of the present invention to provide a method and a computer program product which enables an optimization of oral health, in particular oral hygiene, dental health, jaw health and / or gum health. The invention is preferably also intended to enable control, in particular for continuous or permanent control, or monitoring, in particular for continuous or permanent monitoring, of oral hygiene. More preferably, the invention should be as simple, inexpensive and usable by as many people as possible.

The housing preferably has a coupling interface for defined coupling with an electrical dental treatment agent.

According to a further preferred embodiment of the present invention, the detected movement pattern or the detected movement or the recorded movement course is compared with movement patterns held in a database, deriving or determining correction parameters for adapting the movement of the dental treatment agent as a function of the adjusted movement patterns, movement or Movement course and in real time output of information by means of an output device depending on the derived or determined correction parameters.

The aforementioned task is additionally or alternatively achieved by means of dental treatment, in particular an electric toothbrush. The dental treatment agent according to the invention preferably has a housing for accommodating at least one detection device, the detection device having a sensor device for detecting at least acceleration and / or rotation data, the sensor device being designed as a position, speed, acceleration and / or rotation sensor, a communication device, in particular a Bluetooth interface, for wireless data exchange, in particular with a terminal device, in particular a smartphone or tablet PC or SmartMirror or smartwatch, the communication device transmitting sensor data, in particular in prepared form, to a terminal device, a memory device, a processor device, and an energy supply device for Providing electrical energy for operating the sensor device and the communication device and the processor device and the memory device, the memories being device is provided at least for storing several sensor data of the sensor device resulting from different dental care processes, the sensor data being stored simultaneously on the storage device at least as part of dental care process data for several dental care processes or the sensor data being stored in succession on the storage device as part of dental care process data for several dental care processes , wherein at least temporarily dental care process data, which have sensor data, for several dental care processes are stored on the memory device, the processor device being provided for processing and / or for analyzing the dental care process data, whereby through the analysis of the dental care process data individual or all of the dental care process data for one or more defined user profiles are assignable, preferably at least two user profiles being registered.

An additional or alternative method according to the invention is preferably used to determine a movement or course of movement of a dental treatment agent that results during dental treatment. The method preferably comprises at least the following steps: moving the dental treatment agent for treating surface portions of the teeth at least in an X / Y plane, with at least one optical recording device recording data relating to at least one movement parameter of the head of the person being treated, providing the recorded Data to a processor device for Determining the movement or the course of movement, providing sensor data from one or more non-optical sensor device (s) of a detection device, the detection device being physically connected to the dental treatment agent at least during the dental treatment or being arranged in the region of the dental treatment agent, determining the movement or the course of movement, wherein the sensor device is preferably a position, speed, acceleration, inclination and / or rotation sensor. According to the invention, the orientation of the head relative to the optical detection device is determined by the optical detection device. Additionally or alternatively, the sensor data for determining the course of the movement or the movement are evaluated as a function of a degree of alignment of the head with respect to the optical detection device.

The present invention is thus also based on the finding that the non-optical sensor data are sufficient for detecting the movement course or the movement pattern if the alignment of the head with respect to the optical detection device has a minimum alignment with one another. If it is determined via the optical detection device that the head of the person is aligned sufficiently precisely with respect to the optical detection device, this can rule out that the person is moving inappropriately, i.e. runs through the apartment, rotates, etc. The sensor data of the non-optical and / or optical sensor device are thus recorded in a sufficiently fixed reference system and are therefore sufficient to determine the movement of the dental treatment agent relative to the person's head. With this solution, therefore, a large number of data from different detection devices, in particular one optical and at least one non-optical detection device, need not be recorded and evaluated in combination with one another. Furthermore, the face of a person is easier to grasp visually than a hand or a dental treatment agent. The sensor device is particularly preferably embodied by an inertial sensor system which embodies a plurality of acceleration sensors and at least one rotation sensor, in particular a plurality of rotation sensors.

The degree of alignment preferably describes the portion of the face that can be detected by the face of the person by means of the optical detection device, a message or a signal being output to the person via an output device, in particular a display, or via the dental treatment means, as soon as the degree of alignment falls below a threshold parameter, the message or the signal provides a hint to increase the degree of alignment. Preferably, the message is issued when the degree of alignment is less than 75% or less than 65% or less than 55% or less than 50% or less than 45% or less than 40% or less than 35% or less than 30% or less represents than 25% or less than 20% or less than 15% or less than 10% or less than 5% or less than 3% of the face of the person. The face area is preferably defined by the area between the outer and / or rear ends of the ear cups and between the upper edge of the forehead and the lower edge of the chin.
The sensor data are particularly preferably used to determine the movement, the movement course or the movement pattern if the degree of alignment is more than 15% or more than 20% or more than 25% or more than 30% or more than 35% or more than 40% or more than 45% or more than 50% or more than 55% or more than 60% or more than 65% or more than 70% or more than 75% or more than 80% or more than 85% or more than 90% or represents more than 95% or more than 97% of the face area.

To determine the movement or the course of movement, it is particularly preferred to use only the data recorded by means of the sensor device or the data recorded by means of the optical detection device, in particular a camera.

The face is preferably identified by body points, body lines and / or body surfaces and / or by characteristic features, in particular the position of one or more eyes and / or the nose and / or the mouth and / or one or more ears relative to one another.

The body points, body lines and / or body surfaces and / or the characteristic features are preferably identified by characteristic color distributions or grayscale distributions.

The color distributions or grayscale distributions are preferably described by the data recorded by the optical detection device.

Furthermore, the present invention relates to a method for monitoring dental treatment movements and for outputting correction parameters for adapting the dental treatment movements, at least comprising a method described herein and the steps of comparing the detected movement with movements stored in a database, deriving or determining correction parameters, in particular at least one direction of movement, for adapting the movement of the dental treatment agent in Dependence on the adjusted movements, and the output of information by means of an output device as a function of the derived or determined correction parameters.

Furthermore, the present invention relates to a computer program product for executing a previously mentioned method.

Furthermore, at least one cleaning feature or a plurality of cleaning features for a plurality of teeth is preferably detected or determined.
Before determining the movement, positions of at least one finger, in particular a plurality of fingers, of the hand guiding the dental treatment agent in various relative positions of the dental treatment agent relative to the head of the person are preferably determined in order to determine the respectively treated portions of the teeth. The determination of the movement is preferably based on the relative movement of the reference systems and / or the positions and / or position of at least one finger, in particular at least or exactly 2 or at least or exactly 3 or 4 fingers.
This solution is advantageous because it enables a very precise determination of the tooth portions treated in each case.
Further preferred embodiments are the subject of the subclaims and / or the following parts of the description.
According to a preferred embodiment of the present invention, end positions of the hand guiding the dental treatment agent relative to the head of the person are determined by evaluating the relative positions of the reference system moving with the head of a treated person relative to the further reference system.
According to a preferred embodiment of the present invention, the end position is determined by means of data which are recorded by the optical detection device during the output of dental treatment instructions for treating the back or rear teeth.
An end position preferably denotes an orientation or position of the hand guiding the dental treatment agent relative to the head or the reference system of the head, in which the movement of the dental treatment agent is limited in one or at least one direction relative to the head. In particular, the limit is limited by the accessibility of the teeth or the presence or absence of teeth.
According to a preferred embodiment of the present invention, the body points, body lines and / or body surfaces are each identified by characteristic color distributions or grayscale distributions.
According to a preferred embodiment of the present invention, the position of the at least one finger is at least partially determined by the data which describe the characteristic body points of the hand, body lines of the hand and / or body surfaces of the hand with which the dental treatment agent is guided, and / or further data recorded by means of the optical detection device, in particular surface data of the at least one finger, is described.
According to a preferred embodiment of the present invention, the data describing the position of the fingers are compared with data stored in a memory for determining the orientation of the cleaning surface of the dental treatment agent.

According to a preferred embodiment of the present invention, the color distributions or grayscale distributions are described by the data recorded by the optical detection device. According to a preferred embodiment of the present invention, the end positions are used to determine how long the dental treatment agent is.
According to a preferred embodiment of the present invention, the end positions are used to determine how the relative position of the hand relative to the head is when treating a specific tooth or a plurality of specific teeth, in particular the left and / or right posterior tooth of the upper and / or lower row of teeth the treated person.
According to a preferred embodiment of the present invention, the data additionally represent characteristic anthropometric body points of the hand, body lines of the hand and / or body surfaces of the hand with which the dental treatment agent is guided.
The dental treatment agent is preferably moved at least temporarily three-dimensionally, ie in the X, Y and Z directions, and the movement parameters are particularly preferably recorded depending on the direction and / or orientation. The XY plane is a plane that extends in the X direction and in the Y direction, similarly possible other planes extend, the X / Y / Z axes each being at right angles to one another.
As an alternative or in addition, the present invention can relate to a method for at least partially determining a movement pattern or tooth cleaning characteristic of a dental treatment agent, in particular a toothbrush, which results from a dental treatment, in particular tooth cleaning, the method preferably at least the step of optical Acquisition of data, in particular by means of at least one camera, such as a CMOS camera, a CCD camera, an NMOS camera, a LiveMOS camera or a time-of-flight camera, for at least one movement parameter, in particular the direction of movement or rotation, the acceleration, the distance covered and / or the speed, of a dental treatment agent and the step of pictorial separation of the dental treatment agent, in particular the hand guiding the dental treatment agent, from at least one further B detected by the optical detection device image component by means of a data processing device and the steps of determining at least one movement pattern corresponding to the movement parameter.
This solution is advantageous because the data acquisition takes place both locally and at any time and therefore private individuals can monitor and objectively assess dental treatment at any time, regardless of the time of day. The recorded data are to be prepared in such a way, in particular in real time, or are preferably processed in real time in such a way that, for example, the dentist or the private person or the patient himself can analyze the movement pattern or tooth cleaning feature, thereby making individual adjustments to the movement sequences taking place during dental treatment can be done. The data collected in this way can not only be used individually for the acute optimization of the movement patterns, but can also be used on a larger scale, for example by health insurance companies and / or research institutions. By transmission The data on a central evaluation station, for example, opens up the possibility of processing the generated raw data in a centralized manner with adequate computing power, comparing them with optimal movement schemes and sending them to the local end devices.On the other hand, the data is also provided additionally or alternatively enables large-scale clinical studies for research purposes or for commercial statistical use (e.g. for health insurance companies).
Further preferred embodiments, objects, method steps and configurations are the subject of the subclaims.
In the sense of the present invention, a location detection of the adapter or the dental treatment agent can be carried out approximately by determining the location of the terminal, in particular by means of IP address evaluation and / or satellite-based, for example by means of GPS, Glonass, Galileo or Beidou.
According to a further preferred embodiment of the present invention, a method for determining at least one movement characteristic is provided. The method preferably comprises at least the step of executing the method according to the invention multiple times, in particular on various end devices for recording movement patterns or tooth cleaning features of different people, and preferably their statistical evaluation, it being additionally or alternatively also conceivable that a movement characteristic can be generated or is determinable, and the step of determining at least one matching property, in particular a movement parameter and / or the duration of the dental treatment, the determined movement pattern or the recorded data. This embodiment is advantageous since one or more movement characteristics can be derived from the movement patterns of individual persons, which are representative of the dental treatment behavior of the respective person. However, it is additionally or alternatively conceivable that the movement patterns or movement characteristics of individual persons are to be grouped on the basis of matching features. Furthermore, it is conceivable that a step of comparing the determined movement patterns or the recorded data with characteristic standard data takes place, these being provided in a database, the database being at least partially held locally on a mobile terminal and / or at least partially being held on a server becomes.
Furthermore, it is conceivable that during the use of the device, a step of outputting, in particular optical, haptic and / or acoustic outputting, for information about correction, standard and / or ideal movements, in particular depending on the current one, that is to say in real time, for example Movement pattern or depending on an already determined movement pattern or a movement characteristic is provided. Optical output means here preferably the visual representation of the correction, standard and / or ideal movements on a screen or a projection surface, it being conceivable that visual output can be understood as the representation of individual images and / or an animated film representation. Acoustic output preferably describes the output of certain tones and / or the output of voice instructions. Haptic output can be understood, for example, as a defined output of vibrations. In particular with regard to the optical output, the correction, standard and / or ideal movements can be output alongside, above and / or in comparison with the movement pattern actually detected or with the movement pattern actually detected. Corrective movements can, for example, display a suggestion for a movement change or adaptation compared to the movement pattern recorded. Standard movements can be, for example, the average movements of a defined group of people or the movements known to be optimal from clinical studies. Ideal movements can be movements that are extremely gentle, cleaning and / or time-efficient, etc.
According to a further preferred embodiment of the present invention, a method for monitoring dental treatment movements and for outputting correction parameters for adapting the dental treatment movements is provided. The method comprises the method for at least partially determining a movement pattern of a dental treatment agent, in particular a toothbrush, resulting from a dental treatment, in particular tooth cleaning, with the following steps: moving the dental treatment agent to treat surface portions of the teeth at least in an X / Y plane, whereby data relating to at least one movement parameter of the dental treatment agent, in particular the direction or rotation of the movement, the acceleration, the path and / or the speed, are recorded by means of a preferably optical detection device, in particular a sensor device, and providing the recorded data to a processor device or to a system for determining the movement pattern and the steps of comparing the detected movement patterns with movement patterns held in a database, deriving or determining correction parameters, in particular at least one direction of movement, for adapting the movement of the dental treatment agent as a function of the adjusted movement patterns, and outputting information by means of an output device as a function of the derived or determined correction parameters. This method is advantageous because it involves dental treatment, especially tooth cleaning, the person performing it preferably gives feedback or correction information on the movement sequence or correction information for correcting or adapting the movement sequence can be output to a person performing the dental treatment, in particular in real time, should the tooth treatment agent be evaluated as unsuitable movement, in particular using software technology, or lead to a movement pattern assessed as unsuitable.
This embodiment is advantageous since, for example, children can be taught, in particular monitored, the suitable movement patterns identified with regard to the movement sequences during dental treatment, in particular tooth cleaning. An optical output device, such as the display of a cell phone, a watch, an armband, a game console or a tablet PC, can output an image or a video that shows the child the preferred optimal movement patterns, in particular those in a local storage device and / or a server and / or in a local or internet-based database in data form, visually indicates or outputs movement patterns. The movements of the child can be detected and thus monitored by means of an optical detection device or optical detection device, in particular a camera, which is preferably coupled to the output device in terms of signal technology and is preferably housed in the same housing as the output device. If the child deviates from the displayed movements or movement patterns, then a signal can preferably be output that explains the deviation to the child. The detection device and the output device, in particular for the optical and / or haptic and / or acoustic output of signals and / or instructions, are preferably part of a single device, in particular a mobile device. The device is preferably designed as a portable processor device, in particular as a mobile phone or tablet PC.
According to a further preferred embodiment of the present invention, the teeth to be treated are preferably registered, the registration comprising optical detection by means of the detection device or manual detection by means of an input mask, the number and / or the position and / or the orientation and / or defects of at least individual teeth are recorded, and the derivation or determination of the correction parameters is preferably carried out taking into account the registered teeth. In this case, the input mask can be visualized, for example, via a display device of a terminal, in particular of the terminal which also has the detection device. Preferably, by means of an input device, which can preferably be part of the display device, a person can indicate the number of teeth and / or which position and / or which orientation and / or which defects have individual, several or all teeth.
The correction parameters are preferably derived or determined taking into account the registered teeth. The teeth can be registered, for example, by means of the, in particular optical, detection device, in particular a camera, that is to say at least one image of the dentition is preferably taken, the image being evaluated by software and, for example, the number, orientation and / or position and / or defects in the teeth are detected. It is therefore preferably also possible to detect empty spaces in the dentition.
Additionally or alternatively, it is conceivable that the number, orientation and / or position and / or defects of the teeth can be recorded manually, in particular via an input mask. Additionally or alternatively, the angular feature and / or seals and / or crowns and / or inlays or seals, one or more teeth, can be detected, in particular by means of the optical detection device. The position of the teeth preferably describes the position of the teeth or which tooth the respective tooth is (eg incisors, canine, premolar, molar). It is also conceivable that properties of the individual teeth or relationships between the individual teeth can be recorded.
Defects are preferably understood to be a decrease in gums and / or discoloration and / or tartar and / or cracks and / or breaks and / or holes and / or tartar etc.
Furthermore, it is preferably conceivable for a calibration step to be carried out once or repeatedly or repeatedly. Calibration is preferably understood to mean the determination of the specific or personal properties of the body, in particular the size or the distance of the head from the detection device or a reference point or the size or the distance of a component of the head from the detection device or a reference point. In the calibration, the optical detection device particularly preferably detects a plurality of body-fixed points or surface points, preferably one or more anterior teeth and / or the contact area or boundary area extending in the tooth longitudinal direction between the anterior teeth being detected. These are preferably the central incisors, in particular of the upper jaw, it being conceivable that the central incisors of the lower jaw are also or alternatively captured. The detection of the position of the incisors of the upper jaw and / or the border area between these incisors is often possible with the upper lip raised, but this cannot always be ensured when brushing the teeth. Nevertheless, the detection of the position of the incisors and / or the boundary area between the incisors in relation to others offers anthropometric points of the face surface, in particular the nose, cheeks and forehead region, wrinkles, in particular forehead folds, or the pupils, a possibility of defining an extremely precise coordinate system or reference system on the head of a person. For clinical studies, this should or can preferably be done with established dental coordinate definitions such as, for example, the Frankfurt horizontals; be related to the Camperian plane or the occlusal plane. Furthermore, a coordinate system defined in this way can additionally be coupled to exactly or at least one, two, three further body points or to several body points, in particular the nose, chin, forehead, one ear or two ears, etc. This is advantageous because, on the one hand, the coordinate system that has been defined always remains detectable regardless of the position of the lips, as a result of which the position of the teeth is always known, and on the other hand the shape of the body part, for example the nose, is irrelevant. The soft tissue formation that may occur when opening the mouth should or can be compensated by appropriate correction calculations in order to further increase the accuracy of the method.
According to a further preferred embodiment of the present invention, the optical detection of an object takes place, at least the extent of the object being known in one dimension, ie in the length and / or in the width and / or in the height and / or in the circumference, and the extent of the object in the known dimension or in the known dimensions is preferably used to determine dimension parameters, for example the length of the path covered by the dental treatment agent during a dental treatment and / or the dimensions of the teeth, in particular the visible portions of the teeth, etc. to record. The object here is preferably the person who uses the dental treatment agent, the known dimension of the person preferably being its size. Additionally or alternatively, it is conceivable that the object is the tooth treatment agent, in particular the toothbrush, the known dimension of the toothbrush preferably being the length and / or the width and / or the height and / or the circumference. Additionally or alternatively, it is conceivable that the object is an element whose dimensions are essentially identical everywhere in the world, such as a CD, DVD or credit card. Data on the properties of the dental treatment agent can preferably be recorded using an identification agent (cf. later explanations).
Furthermore, it is conceivable that a sensor device, in particular a pressure sensor, is provided in or on the dental treatment agent or for bringing it into contact with the dental treatment agent, for detecting the contact pressure exerted on the mouth or the teeth and / or the gums by the dental treatment agent. Alternatively or additionally, it is conceivable that the pressure detection is effected by means of the optical detection device. A bend of the dental treatment agent is detected and set depending on known strength values of the dental treatment agent. The strength values can be stored in a database or can be stored. It is also conceivable that the dental treatment agent or the packaging of the same (eg barcode or QR code) is optically recorded and identified. The identification of the dental treatment agent enables the information relating to the specific dental treatment agent regarding its properties, in particular the strength values, to be stored or called up automatically for a processor device. It is also conceivable that the information relating to the properties of a dental treatment agent can also be made available manually in a database, in particular of a mobile terminal, or can be stored or registered. The information relating to the properties can preferably be stored locally in data form on the mobile terminal or on a server. According to a further preferred embodiment of the present invention, a pressure that is exerted on the teeth or gums of the person undergoing dental cleaning during the dental treatment, in particular a tooth cleaning, by means of a dental treatment agent, in particular a toothbrush, is thus preferably determined, with an optical detection of the dental treatment agent , in particular indirectly or directly, by means of the optical detection device, with the detection device capturing image information or generating image data and using the image information or the image data to determine, in particular elastic, deformation, in particular deflection, of the dental treatment agent, the pressure at least is determined as a function of the deformation of the dental treatment agent and preferably further data that include properties of the dental treatment agent. It is also conceivable that, depending on the pressure determined, a signal or information can be output via an output device. The signal or the information preferably represents an action recommendation to the user of the dental treatment agent, in particular to the person who is experiencing the dental treatment. The detection of the pressure or the output of the signals and / or information to be output as a function of the detected pressure is preferably carried out in real time. The signals and / or information are particularly preferably output via an optical output device. The optical output device is preferably part of a device, in particular the terminal, to which the optical detection device also belongs. The signals and / or information for printing are particularly preferably communicated to the same person at the same time and / or via the same output device with which correction parameters for adapting the dental treatment movements to a person, in particular the person who experiences and / or carries out dental treatment, are likewise communicated. The data on the properties of the dental treatment agent can be material properties and / or strength values and / or dimensions and / or bending stiffness and / or make and / or age and / or frequency of use, in particular duration of use, etc.

According to a further preferred embodiment of the present invention, depending on a movement of the body, in particular the head, the person, with respect to which the movement patterns are detected, different points of the body, in particular the head, of the person are defined in relation to the optical detection device Frame of reference. This embodiment is advantageous since the head of the person does not have to be completely stationary when performing the method, but can preferably move and nevertheless an accurate detection of the movement patterns is possible. If, for example, due to a person's head turning, a surface point recorded for the definition of the reference system can no longer be detected, another body-fixed or head-fixed point or surface point or several other body-fixed or head-fixed points or, preferably, before the surface point can no longer be detected. Surface points recorded by means of which the reference system is maintained. In addition to characteristic shapes, such as the tip of the nose, skin discoloration, in particular pigment disorders, pigment nevus, scars, body jewelry, in particular tattoos, the eye sockets, the incisors, in particular the upper jaw, as well as points of the body, in particular, can be used as body-fixed or head-fixed points or surface points attached to the head, such as clothing, hats, glasses.
According to a further preferred embodiment of the present invention, the processor device is a mobile terminal (for example a mobile phone or tablet PC), which sends the recorded data over the Internet to a server device for further processing and / or over the Internet for output by means of an output device of the device receives, the data comprising information relating to movement parameters of the dental treatment agent. Furthermore, the above-mentioned object is achieved by a system for at least partially or at least partially indirectly determining a personal and preferably dynamic movement pattern of a dental treatment agent, in particular a toothbrush, which results during dental treatment, in particular tooth cleaning. A dynamic movement pattern is preferably to be understood here as a movement pattern that is at least partially defined by speed information and / or acceleration information of the dental treatment agent relative to a treatment area. The system preferably comprises at least one detection device, in particular a sensor device or an optical detection device, for recording data on at least one movement parameter, in particular the direction of movement, the acceleration, the distance traveled and / or the speed of the dental treatment agent, and at least or exactly one data processing device to generate movement patterns based on the recorded data. It is conceivable here that the data processing device is preferably a device that can at least temporarily be connected to the Internet, in particular a computer, a digital camera, a game console, a tablet computer, a laptop, a wristwatch (for example a smart watch), a television set and / or a mobile phone , It is also conceivable that the data processing device generates the movement patterns partially or completely. The data processing device particularly preferably transmits the fully or partially generated movement patterns to a server device, which preferably receives personal movement patterns from dental treatment agents from a large number of data processing devices.

The energy criterion preferably represents a state of charge of a terminal, in particular a mobile terminal, supplied with energy, in particular electricity, by an accumulator. This criterion-dependent transmission of the partially or completely generated movement patterns is advantageous since the movement patterns can first be calculated on the side of the data processing device, ie on the terminal side, and the amount of data transfer between the individual terminals and the server unit can thus be kept relatively low. This is also advantageous since the server device must have a significantly lower computing power if it already receives partially or completely prepared movement patterns and can process them further. The server device then preferably does not have to first effect or calculate the complete generation of the movement patterns from the raw data. Alternatively, however, it is also conceivable that the data captured by the detection device are forwarded to the server device for further processing. Forwarding can take place immediately after recording or depending on certain criteria. The criteria can e.g. B. be an energy, connection, time, data volume and / or dental treatment repeat criterion. In this case configuration, the server device can preferably be viewed as a data processing device, ie end users or in the area of the detection device does not necessarily require a data processing device which effects a processing of the recorded data. However, a processor device, in particular a mobile telephone, is preferably provided, which at least causes the data to be forwarded to the server device.

The recorded movement parameters of a specific person are preferably by means of a personalization instance, such as. B. a name query, a password query, a telephone number, an email address or a pseudonym can be assigned to this specific person. This embodiment is advantageous because, by means of the data generated by the server device, consisting of the dental health status, the number of visits to the dentist per year and / or the treatment history and the recorded movement parameters or the movement patterns, clear controls and monitoring can be carried out and lessons for the further improvement of the dental treatment technology are draggable.

The coupling element or the adapter is thus preferably coupled to the guide support structure of a dental treatment agent. This means that the dental treatment agent has a handle part that is in the hand of the person performing the dental treatment when using the dental treatment agent. The adapter or the coupling element is then preferably arranged on the handle part of the dental treatment agent. Furthermore, it is also conceivable, especially in the case of electric toothbrushes, that the detection device is permanently or permanently connected to the electric toothbrush. According to a further preferred embodiment of the present invention, the dental treatment device has a communication interface for transmitting the acquired data, in particular in raw or processed form, to a data processing device, the communication interface being particularly preferably designed in such a way that the data can be transmitted wirelessly.

In this case, the data processing device can use data from one or more or all cameras and / or sensors to determine the movement parameter.
According to a further preferred embodiment of the present invention, the optical detection device has at least one, in particular exactly or at least two, cameras for three-dimensional detection of the at least one movement parameter of a dental treatment agent, the processor device defining a three-dimensional coordinate system or reference system that is defined when the movement of the tooth Dental treatment agent moved in the room with the dental treatment agent. The coordinate or reference system can be formed by characteristic anthropometric body points, body lines and / or body surfaces of a body part of a person, in particular the hand with which the dental treatment agent is guided. However, it can also be formed by surface points, lines and / or surfaces of the dental treatment agent.

This embodiment is advantageous because, at least indirectly, at least indirectly, a movement of any dental treatment means, in particular any commercially available toothbrush or electric toothbrush, can be detected optically, at least indirectly, and the spread of optical detection means, in particular handheld cameras, is very high, as a result of which the invention is applicable to an extremely large number of people. The data processing device particularly preferably identifies and separates the dental treatment agent from the other image components in such a way that its movements, in particular with respect to or relative to a reference or coordinate system defined on the head or in the area of the head of the person, can be detected and particularly preferably evaluated , Furthermore, in particular, preferably at least or exactly one body part of a person can be identified and separated from the other image components by the data processing device in such a way that a movement parameter of the dental treatment agent relative to the body part can be determined or calculated. The body part is preferably part of a head, such as forehead, eyebrows, eye socket, mouth, lips, ears, cheeks and / or chin, preferably one or more body-fixed, in particular skull-resistant, parts such as the forehead, chin and / or the Nose.

Most people always use the same positions when treating the respective teeth, so that the respective positions of the fingers provide immediate information about the position of the dental treatment agent.

6a represents schematically the sensor values recorded during a dental care process. V1 represents an average.

6c also shows schematically the sensor values recorded during a dental care process. The type of dental care procedure is identical here, ie in both cases it is preferably a matter of tooth brushing procedures, in particular by means of an electric toothbrush, in particular using the same electric toothbrush.

6b shows a course V2 , which is characteristic of a user A. This course can be generated or derived from a single dental care process. However, this course preferably represents a standardized course, ie a course generated from a plurality of overlapping courses or one or more partial sequences of courses which match in sections and / or are similar in sections. A similar course in this case preferably describes a slight, in particular minor mean, deviation in the course of the partial sequence with a deviation of less than 50% or less than 40% or less than 30% or less than 20%. The individual partial sequences of the different dental care processes do not have to occur at exactly the same time (e.g. after the start of the respective dental care process), but can occur at different times (e.g. after the start of the respective dental care process). 6d shows a course that is characteristic of user B.

It is possible to use one or more criteria as a basis for analysis. For example, if there is only one criterion, such as the distances between the immediately adjacent peaks 122 . 123 . 133 , then it would not be possible in the present example to assign the curve to a specific user. There 127 and 125 are similar in size. On the other hand, it can be seen that, for example, the maximum values 126 and 124 are clearly different from each other and user A therefore the course V1 can be attributed and the course V3 User B can be attributed. Since maximum values can also result randomly, an average can additionally or alternatively 128 . 129 . 130 . 131 be used. The mean value of V1 is far less than that of V2 than of V4, which is why V1 is also to be attributed to user A. In contrast, the mean lies 130 closer to the mean 131 instead of 129.

The example shows that the individual courses can have a “handwriting” or an unmistakable characteristic that can be determined by one or more criteria.

According to the invention, sensor data or movement profiles that are stored in the same memory or in the same memory device, in particular on the same adapter or the same electric toothbrush, are thus assigned to different user profiles, the assignment being carried out by comparing features with reference sensor data or reference movement profiles.

Thus e.g. two people use the same handpiece (with detection device) of an electric toothbrush without having to connect the toothbrush to an end device or server each time they brush their teeth. Is carried out after e.g. 20 tooth brushing processes, a synchronization of the stored dental care process data with the end device, in particular an app running on the end device, and or the server, the individual tooth brushing processes are assigned to the user profile of the respective person depending on the analysis result.

The same applies when using an adapter.

Families in particular often have an app with multiple users. Cleaning e.g. If the children have their teeth for several days without a device (e.g. smartphone), the dental care process data is not lost, but is also preferably automatically synchronized between the adapter and the device the next time data is connected.
