The present disclosure relates to an education and training system, and more particularly to a clinical dental education and training system capable of instantly recording the operation process and generating result data accordingly.
In present dental teaching and training systems, learners directly perform a dental operation to a dental model of a dummy used for dental teaching, but such teaching method cannot evaluate the learners' performance during the dental operation process. For example, an alveolar bone is drilled with an improper depth, a tooth is drilled and formed into an improper shape, a pulp inside the tooth is damaged during the operation process, or a force with an improper angle is applied to the alveolar bone or tooth, and all of the above situations will cause sequelae after the dental operation. However, it is impossible to conduct evaluation and analysis related of the factors of the above situations during the learning and operation processes through a data-based method except by a teacher's visual examination and guidance, so that the learners can only gain experience from practical operations in the future, and such learning method is quite dangerous to patients.
Therefore, it is a primary objective of this disclosure to provide a clinical dental education and training system and its method, and the system collects related data of a learner's learning behavior during a clinic operation and examines the details of the learner's operation during the learning process by system analysis, scan analysis or AI analysis, and then provides recommendations accordingly to overcome the drawbacks of the conventional operation process. In addition, the system and method of this disclosure have the effects of improving the skill of dental learners, objectively evaluating the teaching performance or index, and providing an evaluation system for the dental education and training.
To achieve the aforementioned and other objectives, this disclosure provides a clinical dental education and training system comprising a handheld positioning portion, a positioning plate, an image tracking and capturing system and a server. The handheld positioning portion comprises a plurality of first positioning marks and is coupled to a drill portion, and the first positioning marks are disposed on the handheld positioning portion and relative to the other side of the drill portion. The positioning plate comprises a plurality of second positioning marks and a bracket, wherein, the bracket is combined with a dental model, so that the positioning plate is fixed in a detection area of the image tracking and capturing device to track the position of the dental model. The image tracking and capturing system obtains the positions of the first positioning marks and converts such positions into a plurality of first positioning signals and also obtains the positions of the second positioning marks and converts such positions into a plurality of second positioning signals. The server pre-stores image data of the dental model and is coupled to the image tracking and capturing system via a signal to obtain the first positioning signals and the second positioning signals and to convert the first positioning signals and the second positioning signals into a plurality of operation signals, and then to analyze and compare the operation signals with the pre-stored course data to generate operational scores and operational error data. The clinical dental education and training system of this disclosure can collect a learner's operation process and generate course data and evaluation scores which are fed back to the learner in order to improve the learner's technical deficiencies.
Preferably, the clinical dental education and training system of this disclosure is capable of storing teaching data and displaying a teaching image included in the teaching data on the screen and provided to the user for a guidance operation. Therefore, this system can guide users to make reasonable determination or decision and can further provide three-dimensional teaching images or other information to assist the users' operation.
Further, the server generates operational scores or operational error data according to the difference between the operation signals and the course data, or performs a path comparison and converts their difference into operational scores or operational error data.
Further, the server is coupled to a scanning device, wherein the scanning device is provided for scanning an operated dental model and transmitting the scan result to the server, so that the server can perform the analysis and evaluation according to the result.
To achieve the aforementioned and other objectives, this disclosure further provides a clinical dental education and training method. Firstly, an image tracking and capturing system is used to obtain positions of a plurality of first positioning marks of a handheld positioning portion and positions of a plurality of second positioning marks of a positioning plate, wherein the first positioning marks are coupled to a drill portion of the handheld positioning portion. The positions of the first positioning marks are converted into a plurality of first positioning signals, and the positions of the second positioning marks are converted into a plurality of second positioning signals. The first positioning signals and the second positioning signals are obtained by the image tracking and capturing system and stored into a server, and the server converts the first positioning signals and the second positioning signals into a plurality of operation signals. The operation signals are analyzed and compared with the stored course data to generate operational scores and operational error data. The clinical dental education and training method of this disclosure collects a learner's operation process and generate course data and evaluation scores accordingly. Therefore, this method is capable of providing an objective comparison standard to teachers and learners, and focusing the operational learning data with a weaker operation (or a relatively higher error rate) to users in order to improve their technical deficiencies.
Preferably, the clinical dental education and training method of this disclosure further comprises the steps of obtaining teaching data and displaying a teaching image included in the teaching data on a screen and provided to users for a guidance operation. Therefore, this system can guide users to make reasonable determination and decision and provide teaching images or other information to assist the users' operation.

The memory unit 503 is telecommunicatively coupled to the processing unit 502 and provided for storing the first positioning signals, the second positioning signals and the operation signals. The analysis unit 504 obtains the operation signals generated according to the user's operating conduct (such as a moving path or a drilling angle) from the memory unit 503, and data analysis or various algorithms of an artificial intelligence (AI) system are used to analyze and compare the operation signal with the course data (such as a standard operation method or a recommended operation method) stored in the memory unit 503, and operational scores and operational error data (such as wrong drilling positions) are generated after the analysis, and then the operational scores are stored into the memory unit 503 may be transmitted to the display unit 501 for a display according to an instruction. The operational error data may be display in form of texts, simulated images, or data on the display unit 501, so that the operator can know the related problem or mistake easily to achieve the effect of improving the technical skills.
The processing unit 502 can further obtain teaching data from the memory unit 503 and display a teaching image included in the teaching data on the display unit 501, so that the operator can practice a surgical operation based on the teaching image of the teaching data, or the processing unit 502 is coupled to a guide module 505 via a signal, and the guide module 505 may be a general display device, a three-dimensional image display device or an indicating lamp. The general display device or three-dimensional image display device is provided for playing the image, and the indicating lamp is provided for indicating a specific position by direct illumination to achieve an instant guidance effect. Both of the course data and the teaching data include a dental cast analysis or selection, a drill analysis and selection, an operation flow, a dental model turning, etc.
The description of the following model is provided to select an optimal drill. By collecting data such as the model number of the drill and the sequence of selected use during the user's turning, an AI system data analysis can explore the turning of a learner in a course. After the learner has practiced the turning for several times, the information including the trend of drill selection, the change of scores, the turning time, etc. will be fed back to the learner as a reference for further corrections and technical skill improvements. For example, in the first time, five types of drills 1, 2, 3, 4, 5 are used in a course A, and the time consumed is 60 minutes, and a score of 80 is obtained. In the second time, three types of drills 1, 3, 5 are used in the same course A, and the time consumed is 50 minutes, and a score of 70 is obtained. In the third time, four types of drills 1, 3, 4, 5 are used in the same course A, and the time consumed is 50 minutes, and a score of 85 is obtained. Therefore, a balance between the turning consumed time and the selection of drills is obtained. Wherein, the relationship between the time, the type of drills and the score can be calculated by an algorithm according to the mutual relation between parameters in order to obtain a corresponding grade. However, the grade is just a basis for judgment only, but not a comprehensive evaluation. The grade represents a distance from the standard operation with good or bad performance in a certain area or a mutual comparison result between groups. In addition, the AI system data can be used to determine or analyze a learner's clinical operation gesture by the algorithm to obtain a custom gesture and path of the learner, so as to determine the reasons of the learner's wrong operation that may occur during the clinical operation, and to provide recommendations for corrections and the best operating mode. Further, this recorded data can be derived to custom data of the learner in the future. In other words, the learner just needs to retrieve the related data of the learner from the system automatically when the learner needs to perform a corresponding surgical operation, and the system can arrange related mechanical equipment to a position which does not interfere with the learner or affect the operation of the equipment according to the learner's custom gesture. In addition, these data are used as a basis for system login to reduce the possibility of various human errors and improve safety.
Further, a scanning device is integrated to the system for scanning a patient's teeth after the clinical operation and the scan result is analyzed and compared with a standard pre-stored in the server, so as to generate a variance analysis result accordingly, and this variance analysis result is used to determine whether or not the scan result falls in a pass range by an algorithm, a proportional analysis, or an appearance analysis. The server may also be integrated with gesture analysis and result analysis to obtain a comprehensive judgment result, so as to avoid neglecting other possibility due to a limitation by existing knowledge.
