Removable Denture Milling with Integrated Artificial Teeth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional CAD/CAM technologies for manufacturing removable dentures face challenges in accurately joining artificial teeth to the denture base and maintaining occlusal relationship reproducibility, leading to issues with restoration accuracy and aesthetics.
Innovation Solution
A method involving the production of three-dimensional data for denture bases and artificial teeth, followed by arranging artificial teeth in a frame body, filling with base resin, and milling the denture using a milling device to create a firmly joined and aesthetically pleasing removable denture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If artificial teeth and denture base are manufactured separately and then joined, then manufacturing flexibility is improved, but joining accuracy and occlusal relationship reproducibility deteriorate
Solution Approach 1:
The patent merges the artificial teeth and denture base into a single integrated block structure before final separation. The artificial teeth are formed as an integral part of the denture base block, ensuring precise spatial relationships and occlusal contacts are maintained throughout the manufacturing process, eliminating joining errors while preserving manufacturing flexibility through subsequent separation and attachment steps.
2Manufacturing precision
If artificial teeth are individually manufactured and joined to denture base, then manufacturing precision of individual teeth is improved, but aesthetics and firmness of joining deteriorate
Solution Approach 1:
The patent combines multiple artificial teeth with the denture base into a single integrated block structure during manufacturing. This integration ensures that the aesthetic surfaces of individual teeth are continuously formed without interruption or additional joining steps, maintaining high aesthetic quality while preserving the manufacturing precision of each tooth through digital design and controlled material removal processes.
3Ease of manufacture
If denture base and artificial teeth are joined after separate manufacturing, then ease of manufacture is improved, but firmness of joining deteriorates
Solution Approach 1:
The patent merges artificial teeth and denture base into a single monolithic block structure during the manufacturing process. This integration eliminates weak joining interfaces by creating continuous material flow between teeth and base, ensuring maximum firmness and strength. The block can subsequently be separated and reassembled with precision, maintaining both ease of manufacture and joining firmness through the integrated structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach enables the manufacturing of high-quality removable dentures with improved restoration accuracy and aesthetics by ensuring precise joining of artificial teeth to the denture base and maintaining occlusal relationship reproducibility.
Implementation Method 1
a milling step of milling the removable denture in which the artificial teeth are arranged on the denture base, by milling, based on the removable denture data, the resin block using a milling device
Data Source
AI summary
Removable denture data of a removable denture is produced, and disk frame data of a disk frame in which the removable denture is accommodated is produced, thereby building the disk frame based on the disk frame data. Next, a resin disk in which artificial teeth are embedded is produced by arranging the artificial teeth in the disk frame and curing a base resin, and a denture base is milled by milling the resin disk based on the removable denture data, thereby manufacturing the removable denture in which a base side of the artificial teeth is embedded in the denture base. As a result, artificial teeth having an excellent aesthetics may be used, it is possible to firmly join the artificial teeth and the denture base to each other, and it is possible to manufacture a removable denture with a favorable restoration accuracy of the artificial teeth.
