Variable-Angle Artificial Tooth Demonstration Tool for Dental Resin Evaluation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dental specialists lack a reliable method to check the performance of dental filling composite resins before purchase, particularly in terms of color tone adaptation, sculptability, and usability for various tooth surfaces, and conventional demonstration tools are unstable when used on uneven tooth surfaces.
Innovation Solution
A demonstration tool comprising artificial teeth with variable angles and a supporting structure body, allowing stable preparation and observation of lost portions and cavities on arbitrary tooth surfaces, including multiple tooth types and variable angles for comprehensive evaluation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional molar with a flat occlusal surface is used for demonstration, then the tooth can be stably positioned, but it cannot demonstrate repair on arbitrary tooth surfaces including buccal and labial surfaces
Solution Approach 1:
The artificial tooth is divided into multiple independent tooth bodies, each having a different surface orientation (occlusal surface, buccal surface, labial surface). This segmentation allows each tooth body to be optimally positioned for demonstrating repairs on its specific surface while maintaining overall system stability through the supporting structure.
Solution Approach 2:
The supporting structure introduces a new spatial dimension by allowing rotation and tilting of tooth bodies relative to the support. This enables arbitrary surfaces of the artificial tooth to be oriented in optimal positions for demonstration, transforming a single fixed-orientation tooth into a multi-orientation demonstration system.
2Adaptability or versatility
If the artificial tooth is made rotatable to access various surfaces, then repair demonstration on arbitrary surfaces becomes possible, but the stability of tooth positioning deteriorates
Solution Approach 1:
The tooth body is designed with rotational capability around the longitudinal axis of the supporting structure. This dynamic feature allows the tooth to be rotated to present different surfaces (occlusal, buccal, labial) for repair demonstration while the supporting structure maintains overall system stability through its fixed base and adjustable mounting mechanisms.
3Adaptability or versatility
If multiple tooth types are included in the demonstration tool, then comprehensive evaluation of dental filling composite resin is enabled, but the device complexity increases
Solution Approach 1:
The supporting structure is designed as a universal platform that can accommodate multiple types of artificial teeth (molars, premolars, canines, incisors). Each tooth type can be mounted on the same support structure, which provides standardized mounting interfaces and rotation mechanisms. This universality enables comprehensive evaluation of dental filling composite resin across different tooth types without requiring separate demonstration tools for each tooth type.

AI summary
The disclosure provides a demonstration tool and a demonstration method that enable stable preparation of each or one of a lost portion and a cavity at an arbitrary site of an artificial tooth, enable repair of the artificial tooth including each or one of the lost portion and the cavity with use of a dental filling composite resin, and then enable observation of a repaired site in a plurality of directions. A demonstration tool is used for demonstration including filling to cure a dental filling composite resin in each or one of a lost portion and a cavity of an artificial tooth, and the demonstration tool comprises at least one artificial tooth including an artificial tooth having each or one of a lost portion and a cavity, and a structure body supporting the at least one artificial tooth, wherein the structure body supporting the at least one artificial tooth is coupled to the at least one artificial tooth, and the at least one artificial tooth has a variable angle.
