Solution Overview

Problem

Current dental teaching models lack realism and precision, as they typically represent healthy teeth without carious lesions, making it difficult for students to practice cutting and preparation skills accurately.

Innovation Solution

A model that reproduces parts of the human or animal stomatognathic system with differentiated areas mimicking various tissues and states, featuring different mechanical properties such as density and color, to provide realistic practice for dental students.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If healthy tooth models are used for teaching, then students can practice cutting instruments freely, but the models lack realism and do not provide guidance for precise cavity preparation

Engineering Contradiction:
Improvefreedom to practice cutting instrumentsVSAvoidprecision in cavity preparation
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The tooth model incorporates areas with different mechanical properties (different density and possibly different color) to distinguish between healthy tooth structure and carious tissue. This local differentiation provides visual and tactile guidance to students, enabling them to identify where cutting should be applied while maintaining the ability to practice freely on the model.

Inventive Principle:
Principle #3Local quality

2Manufacturing precision

If anatomical models with carious lesions are introduced, then realism and guidance are improved, but the models become more complex to manufacture

Engineering Contradiction:
Improverealism and guidance for cavity preparationVSAvoidcomplexity of model structure
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The tooth model is constructed as a composite structure with areas of different density and mechanical properties embedded within the tooth structure. This composite approach allows the model to realistically represent both healthy and carious tissues while providing clear differentiation for educational purposes. The complexity is managed by integrating these different material properties into a unified tooth model structure.

Inventive Principle:
Principle #40Composite materials

AI summary

The invention relates to a model for teaching in dental disciplines, consisting of a structure (1) that reproduces a part of the human or animal stomatognathic system, and which comprises two or more areas (a, b, c, d) with different mechanical properties, differentiated from each other by imitating the different tissues that they reproduce and/or the natural or affected state of same, which areas have a different density and, optionally, a different colour and/or porosity and/or elasticity and/or flexibility. The structure (1) also comprises compatible means (2) for attaching same to a practice phantom.
