3D Dental Training Visualization for Hidden Anatomy Practice
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dental training apparatuses fail to provide realistic and precise practice for complex treatments requiring high accuracy and skill levels, such as dental implant procedures, due to the lack of simulation of invisible portions within the tooth and jawbone.
Innovation Solution
A dental treatment training apparatus that uses predefined 3D information of dental models and treatment instruments, combined with a display unit showing augmented or mixed reality, to superimpose invisible portions and provide precise practice through 3D positional detection and image recognition, allowing trainees to visualize and perform complex treatments accurately.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional dental training apparatuses are used, then basic training can be conducted, but complex treatments involving high accuracy and skill levels cannot be practiced due to lack of simulation for invisible portions
Solution Approach 1:
The patent introduces an intermediary system consisting of a display unit and position detection device that mediates between the trainee and the invisible portions of the dental model. The display unit presents virtual images of invisible portions (such as root canals and jawbone structures) while the position detection device tracks the trainee's actions, enabling practice of complex treatments without direct visual access to the target areas.
Solution Approach 2:
The patent transitions from two-dimensional visual observation to three-dimensional spatial understanding by using a position detection device that tracks the trainee's hand movements and the dental model's position in 3D space. The display unit then presents virtual images corresponding to the invisible portions at the appropriate 3D positions, allowing the trainee to visualize and practice procedures in the hidden dimensions of the dental structure.
2Reliability
If repeated practice is required for high accuracy treatments, then skill level improves, but availability of training apparatuses remains insufficient
Solution Approach 1:
The patent creates a virtual copy of the dental treatment environment using a computer-generated display that replicates the appearance of teeth, gums, and invisible structures. This virtual copy allows repeated practice scenarios without the constraints of physical models or human patients, enabling unlimited repetition for skill development while maintaining high accuracy requirements through precise 3D positioning and visualization.
3Manufacturing precision
If invisible portions are not simulated, then training apparatus structure remains simple, but treatment practice accuracy cannot be achieved
Solution Approach 1:
The patent replaces the need for complex physical simulation structures with a computational system. Instead of physically constructing models of invisible portions, the system uses software to generate and display virtual images of root canals, jawbone structures, and other hidden areas. The position detection device uses optical or electromagnetic fields to track positions, substituting mechanical complexity with computational and field-based approaches.

AI summary
A dental treatment training apparatus allows practice of complex treatments involving high accuracy and skill levels. A dental treatment training apparatus (2) for providing a simulated treatment in which a treatment instrument (80) is applied onto a tooth model (103) includes a display unit (62) that displays, in a superimposed manner, 3D image information based on predefined 3D information about the tooth model (103) and the treatment instrument (80) on a 3D view image (S), a position detector (70) that detects 3D positional information about the tooth model (103), the treatment instrument (80), and the display unit (62), and a control unit (10) that causes the display unit (62) to display, in a superimposed manner, 3D image information corresponding to an item selected on a superimposed selection operation display (C) for allowing selection of an item associated with the simulated treatment based on the 3D positional information detected by the position detector (70).
