A method and a device for practicing dental treatments

Abstract

The present invention relates to a method, system (50), device and an artificial tooth for simulating both pain and anesthesia in a model of jaws, and the tooth is equipped with sensors (56, 57) and connected to a data processing unit (58), memory unit (59) and audiovisual display unit (60). The system (50) is used for the purpose of teaching and practicing in the field of dentistry according to which removing artificial tooth (49) or artificial bone (43, 44) substances by a dental drill (31), generates signals of pseudo pain (62) with different intensities. Signals are fed to the data processing unit (58) which simulates perception of the simulated pain and accordingly to said audio-visual display unit which simulates reaction to the different intensities of generated pseudo pain signals by playing different sounds (64) which are stored in said memory unit. Furthermore, the system is able to simulate anesthesia by generating block signals (68) as a result of applying different anesthetic techniques by means of a dental syringe (33) connected to the system.

Description

technical field [0001] The present invention relates to methods and devices for practicing dental treatment and can be used to simulate pain and anesthesia in dental training models. Background technique [0002] Teaching and training aids for the training and simulation of dental students are already available in the prior art. Document GB 1466907, titled "Dental Patient Simulator", describes a dental patient simulator including a simulated human head, jaw and artificial teeth. Document US5102340 (Berling Hoff et al.) entitled "Dental Teaching and Practicing Apparatus" describes a teaching and training apparatus comprising a small case with an articulated simulated human head. Document JP5204300 (Yamaguchi) entitled "Model Teeth for Dental Teaching" describes a model of the lower jaw comprising artificial teeth. These teeth include materials that exhibit surface anatomical and mechanical properties similar to real teeth, and document EP1912194 (Funakushi et al.) entitled ...

AI Technical Summary

Problems solved by technology

[0012] Third, the required 3D sensors themselves make the overall system expensive

[0013] Fourth, the simulator is commercially more than justifiably priced compared to traditional simulators, although the added functionality is at a premium; for smaller dental schools, even buying a Simulators are also useless

[0014] Fifth, despite the similarity of hand and ear sensations to real dental practice, trainees do not get the feel of working with real teeth or patients

[0015] Sixth, 3D sensors are prone to misalignment, which can lead to processing errors

[0021] Second, compared to traditional simulators, at least due to the dependence on computer equipment and the use of piezo film sensors, it will not be cheaper commercially

[0022] Third, the simulator suffers from biasing the signal generated by the pressure or borehole

[0028] However, if pain simulation is combined with other desired features, such as if pseudo-pain can be blocked by applying local anesthesia techniques to the model, the simulation of the function will be more complicated
