Dental Model Tooth Root Access With Openable Gum Lid
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dental models do not accurately represent the root portion of molar teeth, and there is a need for a dental model that allows for the attachment and detachment of model teeth with a root portion similar to actual teeth, especially for nerve extraction practice.
Innovation Solution
A dental model design featuring a gum portion with an insertion hole and a lid portion that can be opened and closed, allowing the root portion of the model tooth to be exposed and securely attached or detached, using magnetic forces and screw fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the root portion of the model tooth is made smaller than the insertion hole to allow insertion, then the model tooth can be easily inserted into the gum portion, but the root portion shape becomes different from the actual tooth
Solution Approach 1:
The gum portion is divided into a main body and a detachable lid portion. The lid portion can be opened to expose the root portion of the model tooth, allowing the root portion to have the correct shape similar to actual teeth while still enabling easy insertion through the closed state of the lid.
Solution Approach 2:
The lid portion is designed to be movable between closed and open states. When closed, it maintains the appearance of natural gum and allows easy insertion. When opened, it exposes the root portion for observation or procedures, dynamically adapting to different operational needs.
2Shape
If the root portion is made larger to match actual teeth, then the root portion shape becomes similar to actual teeth, but the model tooth cannot be easily inserted into the insertion hole
Solution Approach 1:
The insertion hole is segmented into two parts: a first insertion hole in the main body gum portion and a second insertion hole in the detachable lid portion. This segmentation allows the model tooth to be inserted through the lid portion when opened, maintaining the correct root portion shape while enabling easy insertion.
Solution Approach 2:
The detachable lid portion acts as an intermediary component. It provides an additional insertion pathway when opened, mediating between the need for a large root portion shape and the need for easy insertion by offering an alternative route through the lid's opening.
3Adaptability or versatility
If the lid portion is made detachable to expose the root portion, then the root portion can be observed and procedures can be performed, but the device complexity increases
Solution Approach 1:
The gum portion is segmented into a main body and a detachable lid portion with simple engagement features. This segmentation provides adaptability for exposing the root portion while keeping the overall structure relatively simple through minimal additional components.
Solution Approach 2:
The detachable lid portion serves multiple functions: it maintains the appearance of natural gum when closed, provides an insertion pathway when opened, and allows exposure of the root portion for observation or procedures. This multi-functionality increases adaptability without proportionally increasing complexity.

AI summary
Provided is a dental model in which a model tooth having a root portion similar to an actual tooth is attachable to and detachable from a gum portion, and an articulator. A dental model 1 according to the present disclosure includes: a gum portion 12 in which an insertion hole 20 to which a model tooth 50 is to be inserted is provided; and a lid portion 13b provided on an oral side of the insertion hole 20 in the gum portion 12, in which the lid portion 13b constitutes a part of the gum portion 12 in a closed state, and provides a recess portion 18b that is continuous from the insertion hole 20 and exposes at least a part of a root portion of the model tooth in an opened state, and in which the lid portion 13b is configured to be opened and closed relative to another portion of the gum portion 12.
