Denture Abutment Holding Attachment for Precise Cutting Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing denture abutments lack efficient means to determine the orientation of materials relative to cutting machines, leading to potential misalignment and inefficiencies in the cutting process.
Innovation Solution
A holding attachment with a round or substantially round columnar held portion and a corresponding mounting portion that includes pins and engagement features for aligning with the cutting machine's pin insertion holes and rotation stoppers, allowing easy determination of the material's direction before cutting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If no specific alignment mechanism is provided between the holding attachment and cutting machine, then the device complexity is reduced, but the manufacturing precision and orientation accuracy deteriorate
Solution Approach 1:
The holding attachment serves as an intermediary component between the cutting machine and the denture abutment material. It includes a mounting portion with pin insertion holes and rotation stoppers that interface with the cutting machine, and a holding portion that secures the material. This intermediary structure enables precise alignment and orientation determination without requiring direct complex integration between the cutting machine and material, thus improving manufacturing precision while maintaining reasonable device complexity.
2Measurement precision
If a detailed alignment mechanism with pins and rotation stoppers is added to the holding attachment, then the orientation determination accuracy improves, but the ease of manufacture deteriorates
Solution Approach 1:
The holding attachment is pre-manufactured with precisely positioned pin insertion holes and rotation stoppers that establish the orientation reference framework before the actual cutting process. This preliminary preparation of alignment features allows for accurate orientation determination during cutting without requiring complex real-time adjustment mechanisms, thereby improving measurement precision while keeping the manufacturing process manageable through standardized pre fabrication.

AI summary
A holding attachment includes a holding portion with a round or substantially round columnar hole shape in which a held portion of a material before cutting is inserted and a mounting portion that is mounted on a work mount of a cutting machine. The mounting portion includes at least one pin that is inserted to at least one pin insertion hole provided in the work mount and at least one engagement portion that is engaged with at least one rotation stopper provided in the work mount. A position reference portion of the material before cutting is recessed from a round or substantially round columnar outer peripheral surface of the held portion. The holding portion includes a fitting portion fit to the position reference portion of the material before cutting.
