Denture Tooth Adjustment Using Deformable and Fixed Gingiva
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dentures often fail to adequately adjust to individual patient requirements, compromising comfort, occlusion, phonetic capabilities, and aesthetics due to varying physiological conditions.
Innovation Solution
A computer-implemented method for adjusting the position of artificial teeth using digital 3D modeling, incorporating deformable and fixed gingiva sections to preserve the fit and occlusion while allowing for adjustments to the patient's unique anatomical structure, utilizing CAD/CAM for precise denture design and manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the position of artificial teeth is adjusted to meet individual patient requirements, then the comfort and aesthetics are improved, but the occlusion and phonetic capabilities may be compromised
Solution Approach 1:
The artificial gingiva is segmented into deformable and fixed sections. The deformable gingiva section allows positional adjustment of the dental arch while the fixed gingiva section maintains stable occlusion and phonetic characteristics, resolving the contradiction between adaptability and reliability
Solution Approach 2:
The deformable gingiva section is designed to be dynamically adjustable, allowing the dental arch position to be modified while maintaining stable fixed sections that preserve occlusion and phonetic capabilities
2Ease of operation
If the dental arch position is adjusted relative to the fixed gingiva section, then the fit on supporting tissue is improved, but the gingival shape may be distorted
Solution Approach 1:
The artificial gingiva is divided into deformable and fixed sections, allowing the deformable section to accommodate positional adjustments while the fixed section preserves the natural gingival shape and appearance
Solution Approach 2:
Different sections of the gingiva have different properties: the deformable section is designed to change shape for fit adjustment, while the fixed section maintains the natural gingival appearance, achieving both good fit and aesthetic appearance

AI summary
The invention relates to a computer-implemented method for adjusting a position of artificial teeth of a denture. A digital 3D model of the denture comprising at least a denture part is provided. The denture part is configured for a jaw of a patient and comprises a dental arch with a plurality of artificial teeth arranged in an artificial gingiva. A deformable gingiva section of the artificial gingiva is defined between the teeth of the plurality of artificial teeth and a fixed gingiva section of the artificial gingiva with a fixed geometrical form. The dental arch is moved as a whole relative to the fixed gingiva section in order to adjust the position of the dental arch. A geometrical form of the deformable gingiva section is deformed due to the moving of the dental arch, whereas the fixed gingiva section maintains the fixed geometrical form.
