Layer-Specific Tooth Molding Matrices for Durable 3D Reconstruction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for reconstructing teeth, such as using veneers, are limited by their short duration and lack of individual adjustment to the patient's anatomical and aesthetic features, leading to a need for a more durable and customized solution.
Innovation Solution
A computer-implemented method and system for generating layer-specific molding matrices based on 3D digital models of teeth, allowing for layer-by-layer reconstruction using a set of templates that can be precisely adjusted to fit individual patient requirements, ensuring strong and long-lasting results that match the natural appearance of the teeth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If veneers are used to cover ground down teeth, then the teeth appearance is improved, but the duration of the reconstruction is limited
Solution Approach 1:
The tooth reconstruction is divided into multiple layers (enamel outer layer, enamel inner layer, dentin layer) that are applied sequentially. Each layer is formed using a separate molding matrix and can be individually customized, allowing for a more durable and structurally sound reconstruction compared to a single veneer piece.
2Ease of manufacture
If standard reconstruction methods are used, then the process is simple, but the adjustment to individual patient requirements is insufficient
Solution Approach 1:
Each layer of the tooth reconstruction can be individually customized in terms of geometry, material composition, and physical properties. The molding matrices allow for layer-specific adjustments to match the patient's anatomical structure and aesthetic requirements, with each layer potentially having different characteristics optimized for its specific function and location.
3Manufacturing precision
If layer-by-layer reconstruction with multiple molding matrices is implemented, then the precision and durability of reconstruction is improved, but the device complexity increases
Solution Approach 1:
The molding matrices are pre-fabricated based on digital impressions and treatment planning before the actual tooth reconstruction procedure. This preliminary preparation allows for precise customization of each layer's geometry and properties, ensuring high manufacturing precision while streamlining the clinical application process by having all components ready in advance.

AI summary
The invention relates to a computer-implemented method for providing a set of layer-specific molding matrices for reconstructing layer-by-layer one or more teeth of a set of teeth in a patient's oral cavity. The set of layer-specific molding matrices comprises two or more layer-specific molding matrices. Each of the layer-specific molding matrices is configured for being arranged on the set of teeth and for casting a different layer of the one or more teeth to be reconstructed with a layer-specific reconstruction material inserted into the respective layer-specific molding matrix. The respective layer-specific molding matrix defines a 3D geometric form of the respective layer being casted.
