background
In recent years, oral cleaning has been receiving more and more attention, and poor oral cleaning is an important cause of dental diseases. Daily tooth cleaning is mainly used for cleaning food residues and dental plaque attached to tooth surfaces and gingival sulcus. The conventional toothbrush is a toothbrush having bristles, and a user cleans parts to be cleaned by changing the position of the toothbrush. The tooth socket type toothbrush generally refers to that after the tooth socket is placed on a dental arch, the tooth part needing to be cleaned can be brushed simultaneously without moving the tooth socket by a user. The tooth socket type toothbrush achieves the purpose of quickly cleaning teeth by simultaneously brushing the teeth after the tooth socket is brought to the upper dental arch and the lower dental arch. However, in actual conditions, the condition of each oral cavity is different, so that the popular tooth socket cannot be applied to each oral cavity, a good cleaning effect cannot be achieved, and the purpose of protecting each tooth cannot be achieved, so that the individuation and customization of the tooth socket type toothbrush are the development trend in the future oral cavity cleaning field. In addition, the current mainstream tooth cleaning tools only adopt one of a bristle type toothbrush, a tooth rinsing device, a sound wave vibration, ultrasound or dental floss for cleaning, and the single cleaning mode causes that the cleaning tools are difficult to achieve good cleaning effect. Therefore, it is a technical difficulty to customize the dental mouthpiece type cleaning tool and integrate the cleaning method of the dental mouthpiece type cleaning tool.

Detailed Description
In order to make the objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. The present description provides various examples to illustrate the technical features of various embodiments of the present invention. The steps and the arrangement of the elements in the embodiments are illustrative and not meant to limit the invention.
FIG. 1 is a flow chart of one method of implementing a dental appliance based on biomechanical design, which may include: step S1, establishing an oral cavity biomechanics database; step S2, establishing a tooth socket model database; step S3, collecting oral clinical data of a user; step S4, selecting proper tooth socket model data; step S5, designing a personalized tooth socket; step S6, computer aided simulation; step S7, carrying out physical simulation; step S8, manufacturing a final tooth socket; and step S9, optimally designing and manufacturing the tooth socket according to the use condition of the user. It should be noted that the present invention is not limited to the steps and the execution sequence of the steps shown in the present embodiment, for example, in some embodiments, step S7 may not be executed, step S3 may be executed before step S1, and steps S5 and S6 may be executed in the same step. The embodiments of the individual steps are detailed below:
In step S1, a plurality of tooth model data and effect data achieved by a plurality of tooth cleaning methods are simulated and collected. In one embodiment, the dental model data may be collected by clinical examination, plaster model, CT scan, digital intraoral scan, or camera photography, wherein the dental model data may include one or more of arch shape, interproximal size, periodontal pocket depth, gingival sulcus depth, and tooth size. For example, tooth size can be characterized by parameters such as tooth length, width, and height; the tooth crowding (expressed by the tooth spacing size, which means the width occupied by two teeth subtracted from the sum of the widths of two adjacent teeth) can be divided into four categories, wherein the crowding degree of 1 category is the tooth spacing size =0mm, the crowding degree of 2 category is 0mm < the tooth spacing size is less than or equal to 0.4mm, the crowding degree of 3 category is 0.4mm < the tooth spacing size is less than or equal to 0.8mm, and the crowding degree of 4 category is the tooth spacing size > 0.8mm, but the invention is not limited to this, for example, the tooth crowding can be divided into four categories, and then the tooth spacing sizes of the labial side, the lingual side, the mesial side and the distal side of the teeth at different tooth positions can be judged to belong to which of the four categories; the depth of the periodontal pocket (expressed by the depth of the periodontal pocket) may be divided into four groups, wherein 1 group is 0 mm. ltoreq. the depth of the periodontal pocket.ltoreq.2 mm, 2mm < the depth of the periodontal pocket.ltoreq.4 mm, 3 groups are 4mm < the depth of the periodontal pocket.ltoreq.6 mm, and 4 groups are > 6mm, but the present invention is not limited thereto, and for example, the depth of the periodontal pocket may be divided into four groups, and the depths of the periodontal pockets on the buccal side, the lingual side, the mesial side, and the distal side of teeth at different dental sites may be determined to belong to which of the four groups. If the interproximal size and the peri-alveolar depth are classified into four categories, there may be sixteen cases per tooth and 512 cases per 32 teeth. The tooth model data can also comprise adhesion force data of impurities such as dental plaque, food residues, tooth stains and the like in the oral cavity attached to different parts of the teeth, wherein the adhesion force data can be determined by measuring the cleaning effect of the impurities attached to the teeth by using sensors under different water pressure. In an embodiment, the simulation and collection of the effect data achieved by the plurality of tooth cleaning methods may include cleaning effect data achieved by using a water flow washing, brushing, sound wave or ultrasound cleaning method, damage data caused by the various cleaning methods to the tooth tissue and/or the periodontal tissue, and restoration data after self-restoration of the tooth tissue and/or the periodontal tissue after a period of time, but the present invention is not limited thereto, for example, the effect data may include only one of the cleaning effect data, the damage data or the restoration data. In one embodiment, the adhesion data, cleaning effect data, damage data or restoration data of each tooth can be simulated and collected according to the crowding degree of teeth at different positions and the depth of the periodontal pocket, and the tooth model data and the effect data achieved by a plurality of tooth cleaning modes are imported into computer data processing software (such as ABAQUS) for subsequent analysis or modeling. In one embodiment, the oral data is imported into computer data processing software for analysis in stl format files, for example, using the gridding physician function in the Geomagic software to divide the teeth into grids to accurately confirm the position of the holes in the teeth. In one embodiment, after the parameter data such as the tooth space size, the periodontal pocket depth, the gingival sulcus depth and/or the tooth size in the tooth model is added to the finite element analysis software (e.g. ABAQUS), the finite element analysis software is used to perform the biomechanical analysis on the tooth tissues such as the gingival tissue, the periodontal tissue, the enamel, the cementum and the dentin in the tooth model, and the biomechanical analysis is performed on the impurities such as food residue and dental plaque simulated by adding a part of the modules on the tooth surface.
In step S2, a mouthpiece model database corresponding to a plurality of tooth models is created based on the result of the biomechanical analysis. Specifically, the parameters of each mouthpiece model may include one or more of the number, position, shape, size and water pressure of the water outlet nozzles at each tooth position inside the mouthpiece, the shape distribution of the water pipe inside the mouthpiece, the water flow strength in the water pipe, the position, thickness, hardness or length of the bristles, the angle between the bristles and the long axis of the teeth, the number and power of the ultrasonic working heads, the diameter and distribution of the water return head and the water return pipe, the pressure of the water return chamber, and the like. In one embodiment, the parameters of the mouthpiece model may be set according to the periodontal pocket depth in the tooth model data, for example, if the periodontal pocket depth is 0-2mm, the angle of the bristles to the long axis of the tooth is set to 45 degrees; if the depth of the periodontal pocket is 2-4mm, setting the angle between the bristles and the long axis of the teeth to be 40 degrees; if the depth of the periodontal pocket is 4-6mm, the angle between the bristles and the long axis of the teeth is set to 35 degrees. In one embodiment, the parameters of the mouthpiece model may be set according to the size of the tooth space in the tooth model data, for example, if the size of the tooth space is 0-0.4mm, the length of the bristles is set to 0.5 cm; if the size of the interdental space is 0.4 to 0.8mm, the length of the bristles is set to 0.6 cm. In one embodiment, the mouthpiece model may have a plurality of operation modes, including one or more of a brushing mode, a rinsing mode, a whitening mode, a getting up mode, a sleeping mode, or a postprandial mode. For example, the bristles, the water outlet nozzle and the ultrasonic working head at the same tooth position are set into a first functional group and a second functional group, wherein the first functional group is started when the tooth socket model is set in the getting-up mode; the second functional group is activated when the mouthpiece model is set in the sleep mode. The first functional group and the second functional group are arranged and respectively work independently, so that the damage to the teeth caused by repeated action of mechanical force in the same direction can be reduced, and if the self-repairing function of the teeth and periodontal tissues is considered, the tooth socket type cleaning tool disclosed by the invention can avoid the damage to the teeth in the process of cleaning the teeth. For example, in one embodiment, the bristles, the water outlet nozzle and the ultrasonic working head at the same tooth position can be arranged into a first working group, a second working group and a third working group; in one embodiment, the first working group may be set in a first mouthpiece model and the second working group may be set in a second mouthpiece model, wherein both the first mouthpiece model and the second mouthpiece model are adapted to the same tooth model, and the user may remove the tooth damage caused by cleaning the teeth by means of the first mouthpiece model and the second mouthpiece model respectively and successively.
in step S3, user oral data is collected to obtain a user tooth model. For example, the data of the dental model in the oral cavity of the user may be acquired through clinical examination, a plaster model, CT scanning, digital intraoral scanning or camera shooting methods, in an embodiment, the plaster model corresponding to the data of the oral cavity of the user may be acquired by clinically acquiring the upper and lower dental models of the user and then performing plaster perfusion, and then the plaster model is converted into an stl format file by a digital scanner and then is introduced into a computer for storage and analysis, where the computer may include a personal computer, a workstation, a tablet computer, a smart phone, and other devices. In one embodiment, the clinical data of the user such as the size of the interdental space, the depth of the periodontal pocket, the position easy to be plugged with teeth and the position easy to be calculus are collected as much as possible, so that the established tooth model of the user is more accurate and reliable. In one embodiment, the stl format file and the user's clinical data may be added to data processing software such as Geomagic software and ABAQUS software and finite element simulation analysis software to determine the tooth model and its parameters corresponding to the user's oral data. For example, in one embodiment, the clinical data of the user further includes characteristic data such as age, gender, history of smoking, presence or absence of systemic disease, arch shape (square, oval, cuspate) or size of opening.
in step S4, a mouthpiece model suitable for the user 'S oral cavity data is selected from a pre-stored mouthpiece model database according to the user' S oral cavity data. In one embodiment, the oral cavity data of the user is compared with the oral cavity data stored in the mouthpiece model database, and the pre-stored mouthpiece model corresponding to the oral cavity data with the highest similarity to the oral cavity data of the user is selected as the mouthpiece model suitable for the user. In one embodiment, the similarity may be determined by the sum of absolute values, variance, or standard deviation between the user's oral cavity data and the oral cavity data in the mouthpiece model database. For example, if the pre-stored mouthpiece model database X includes m sets of oral cavity data, each set of oral cavity data includes n parameters, and Y represents the user oral cavity data, the ith set of jth oral cavity parameters in the pre-stored mouthpiece model database may be represented as Xij (e.g., the size of the tooth space of the third set of oral cavity data in the mouthpiece model database may be represented as Y31), and the jth oral cavity parameter in the user oral cavity data Y may be represented as Yj (e.g., the size of the tooth space of the user may be represented as Y1), which set (the sum of absolute values between Xij and Yj) the oral cavity data in the pre-stored mouthpiece model database with the highest similarity to the user oral cavity data is determined by using a formula, but the invention is not limited thereto. For example, in some embodiments, the determining of the similarity may further include normalizing the oral cavity parameters.
In step S5, parameters of the mouthpiece model are adjusted based on the user oral data on the basis of the mouthpiece model selected from the pre-stored mouthpiece model database to be more suitable for the user to obtain personalized parameters of the user mouthpiece model corresponding to the user oral data, wherein the parameters of the mouthpiece model are adjusted based on a result of the biomechanical analysis performed on the user oral data. In an embodiment, the user's opinion is also considered to adjust parameters of the user mouthpiece model and/or set parameters of the main machine of the mouthpiece type cleaning tool, wherein the parameters of the user mouthpiece model may include one or more of the number, position and shape of the water outlet nozzles to be designed at each tooth position inside the mouthpiece, the shape distribution of the water pipe inside the mouthpiece, the water flow intensity inside the water pipe, the positions of the bristles, the angles between the bristles and the tooth long axis, the thickness, hardness and length of the bristles, the number and power of the sound wave vibration emitters or ultrasonic working heads, the diameters and distribution of the water return heads and the water return pipe, the pressure of the water return chamber, and the like. For example, if the angle between the brush and the long axis of teeth set in the mouthpiece model selected from the pre-stored mouthpiece model database to be more suitable for the user is 40 degrees (the depth of the corresponding peridental pocket in the pre-stored mouthpiece model database is 3 mm), and the depth of the peridental pocket of the two users is 3.8mm, the angle between the brush and the long axis of teeth in the mouthpiece model of the user can be set to 43 degrees. For example, in one embodiment, if the oral data of the user is the same or close to the same, the parameters of the mouthpiece model selected from the pre-stored mouthpiece model database may not need to be adjusted.
The achieved cleaning effect of the user-customized mouthpiece model may be simulated using a computer in step S6 to determine whether the personalization parameters of the user mouthpiece model determined in step S5 are appropriate. It should be noted that the above cleaning effect refers to the degree of cleaning of the user's teeth without causing damage to the user's teeth. In one embodiment, finite element analysis software may be utilized to simulate the plaque, food debris and/or stains adhering to the user's teeth and to simulate the cleaning effect of the user-customized mouthpiece model on the impurities adhering to the teeth. However, the present invention is not limited thereto, for example, in an embodiment, if the cleaning effect is not ideal (for example, there are situations that the cleaning degree of the impurities is not enough, the teeth are damaged, etc.), the step S6 may be skipped to re-determine the personalized parameters of the user mouthpiece model corresponding to the user oral cavity data.
In step S7, the 3D printing produces a user mouthpiece model that fits the user' S teeth model. The tooth socket type cleaning tool comprises a tooth socket model and a main body corresponding to the tooth socket model, wherein the main body possibly comprises a return water bin, a water outlet bin, a pressure pump, a charging interface, a disinfection bin, a control panel and other modules, and the main body is used for supporting and matching the tooth socket model to work. In one embodiment, impurities such as dental plaque, food residues and tooth stains can be preset on the user tooth model printed in 3D mode, the cleaning effect of the cleaning tool on the tooth model is simulated, and if the cleaning effect on the teeth is not good, the tooth socket model is improved. However, the present invention is not limited thereto, and for example, in one embodiment, a body suitable for a user's mouthpiece model may be 3D printed out, and the mouthpiece model and the body may be combined into a complete mouthpiece type cleaning tool to verify the cleaning effect on the 3D printed user's tooth model, for example, the cleaning effect in a wet environment at 37 ℃. In one embodiment, if the cleaning effect of the mouthpiece model or the mouthpiece-type cleaning tool is not good enough, the step S5 is returned to redesign the personalized mouthpiece model of the user; if the cleaning effect of the mouthpiece model or the mouthpiece type cleaning tool is expected, the final personalization parameters of the user mouthpiece model, and even the final personalization parameters of the mouthpiece type cleaning tool main body, are determined. In an embodiment, if the user facing model or the facing type cleaning tool manufactured by 3D printing can achieve a better cleaning effect, the user can directly use the user facing model or the facing type cleaning tool manufactured by 3D printing.
In step S8, a personalized mouthpiece-type cleaning tool is made according to the final personalized parameters of the user mouthpiece model. In one embodiment, the number and positions of the core components, such as the water flow pipe, the ultrasonic pipe, the tooth rinsing device nozzle, the ultrasonic working head, the ultrasonic pipe, the bristles and the like, inside the mouthpiece model are determined, then the core components are fixed, and then the periphery of the core components is filled with a suitable material to form a final mouthpiece model suitable for a user of the user's teeth model. In an embodiment, the filled mouthpiece model can be further modified by digital cutting according to the oral cavity conditions of the user (e.g., the depth of the labial-buccal sulcus and the position of the labial-buccal frenulum of the user) to enhance the aesthetic appearance and comfort of the final mouthpiece model. For example, in one embodiment, the dental mouthpiece cleaning tool is manufactured according to final personalized parameters of a main body of the user mouthpiece model, and the final personalized parameters of the main body may include, but are not limited to, the size and position of a water return chamber, a water outlet chamber, a pressure pump, a charging interface, a sterilization chamber, a control panel, and the like in the main body.
In step S9, the mouthpiece model parameters are updated and adjusted according to the user usage. In one embodiment, the user's usage data of the dental mouthpiece cleaning tool or the oral data after using the dental mouthpiece cleaning tool is tracked and recorded by providing an ultrasonic probe, an image recorder or a content detector within the dental mouthpiece cleaning tool, for example, the usage data may include the number of times the user uses the dental mouthpiece cleaning tool and the time point, and the oral data may include gingival atrophy of the user with age or a change in the content detected blood content, which may be indicative of whether the user's periodontal disease is aggravated or alleviated. In one embodiment, the usage data and/or oral data of the user can be transmitted to a server via a data transmission module in the dental mouthpiece cleaning tool, so that the usage data and/or oral data of the user can be monitored or obtained at any time, and whether to adjust parameters of the dental mouthpiece cleaning tool can be determined after analyzing the usage data and/or oral data (e.g., biomechanical analysis), and if the parameters of the dental mouthpiece cleaning tool need to be adjusted, an adjustment value of the parameters of the dental mouthpiece cleaning tool can be obtained, and the adjustment value can be used to individually adjust the dental mouthpiece cleaning tool of the user, thereby generating a new dental mouthpiece model suitable for the user. In one embodiment, the user's usage data of the dental mouthpiece cleaning tool and/or oral data after using the dental mouthpiece cleaning tool may be viewed via application software (APP). In one embodiment, a mouthpiece model corresponding to the user's updated oral data may be selected from a mouthpiece model database based on the user's updated oral data, and then the user's mouthpiece-style cleaning tool may be personalized based on the mouthpiece model. In one embodiment, the results of analyzing the user's updated oral data are added to the oral biomechanics database. In one embodiment, the generated new mouthpiece model is added to the mouthpiece model database.
