Description

Method for determining movement patterns in a dental treatment

The invention relates to a system and a method for determining movement patterns in a dental treatment, in particular the cleaning of teeth. 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

Dentist's instructions as to the frequency, duration and nature of the treatment are easily forgotten, or over time, exercise in a less than optimal manner, which will not optimally ensure oral hygiene or damage to the oral cavity, especially solid and / or soft oral components, e.g. of the teeth, jaw and / or gums.

Document EP 1 379 149 B1 discloses a method of monitoring the position of a toothbrush relative to a person's teeth, the method comprising: providing a toothbrush with a first toothbrush

Position sensor, wherein the first position sensor is at least responsive to changes in position and orientation, providing a second position sensor in fixed positional relation 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 expensive sensors have to be defined on a face, making the system expensive and complex, making 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 that visually detects the movement of the toothbrush, which is disadvantageous because the detected movements are undefined in the room, causing a movement of the toothbrush In addition, elaborate modifications of the toothbrush are required, making the system complex and expensive and thus also inaccessible to a mass market, and the system must be installed in a fixed space for a camera to define the modified one

Toothbrush can recognize.

Furthermore, both systems are based on given datasets, whereby an improvement of the knowledge about Zahnputzbewegungen is not possible.

It is therefore an object of the present invention to provide a method and a system which enables an optimization of oral health, in particular oral hygiene, dental health, jaw health and / or gum health.

The detection of the pressure or the output of the output as a function of the detected pressure signals and / or information is preferably carried out in real time. Particularly preferably, the output of the signals and / or information takes place via an optical output device. The optical output device is preferably part of a device, in particular of the terminal, to which the optical detection device also belongs. Particularly preferably, the signals and / or information for printing at the same time and / or the same output device to the same person

Furthermore, the above-mentioned object is achieved by a system for determining, at least partially or at least partially indirectly, a person-related and preferably dynamic movement pattern of a dental treatment, in particular a dental cleaning, of a

The energy criterion preferably indicates a state of charge of a terminal supplied by an accumulator with energy, in particular electricity, terminal, in particular a mobile terminal. This criterion-dependent transmission of the partially or completely generated movement patterns is advantageous, since the calculation of the movement patterns initially takes place on the side of the

Data processing device, d. H. terminal side, can be done and thus the amount of data transfer between the individual terminals and the server device can be kept relatively low. Furthermore, this is advantageous because the server device must have a significantly lower computing power if it already receives partially or completely processed motion patterns and can process them further. The server device then preferably does not first have to cause or calculate the complete generation of the movement patterns from the raw data. Alternatively, however, it is also conceivable that the data acquired by the detection device for

Further processing be forwarded to the server device. The forwarding can take place immediately after the detection or depending on certain criteria. The criteria can be z. B. be an energy, connection, time, data volume and / or dental treatment repeatability criteria. In this case, the server device may preferably be regarded as a data processing device, ie, on the end user side or in the area of the detection device, a data processing device which does not necessarily require a data processing device Preparation of the collected data causes.
