Dental Blank Insert for Abutment Alignment and Aesthetics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for producing dental restorations face challenges in achieving precise alignment and securing of prosthetic components, particularly with composite materials, which are difficult to work with due to their high translucency and lack of precision in joining ceramic or composite abutments and fixtures.
Innovation Solution
A dental blank comprising a block and an insert with an anti-rotation element, where the insert is designed to provide a secure form-locking connection with the abutment, made from materials like oxide or silicate ceramics or composite materials with low translucency, ensuring proper alignment and invisibility of the abutment during implantation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If abutments are made from titan to ensure biocompatibility and precision, then manufacturing precision and biocompatibility are improved, but visibility of the abutment increases making it aesthetically unacceptable
Solution Approach 1:
The patent introduces an insert as an intermediary component between the titanium abutment and the prosthetic crown. This insert has a translucency of less than 15% to mask the visible titanium abutment, while maintaining the precision benefits of the titanium fixture. The insert acts as a mediator that resolves the conflict between biocompatible precision materials and aesthetic requirements.
2Object-affected harmful factors
If composite materials are used for abutments to reduce visibility, then translucency is improved, but manufacturing precision and joining reliability deteriorate
Solution Approach 1:
The patent divides the restoration system into separate functional segments: a titanium fixture for osseointegration and precision, an insert for aesthetics with low translucency, and a prosthetic crown for function. This segmentation allows each component to be optimized for its specific purpose without compromising overall performance.
Solution Approach 2:
The patent employs a composite structure combining titanium (for mechanical strength and precision), an aesthetic insert material (for low translucency), and ceramic or composite crown materials. This composite approach leverages the advantages of each material while mitigating their individual disadvantages.
3Ease of manufacture
If traditional joining methods are used for abutments and fixtures, then ease of manufacture is maintained, but alignment precision and connection reliability deteriorate
Solution Approach 1:
The insert is pre-formed with precise positioning elements and anti-rotation features before being integrated into the final assembly. This preliminary preparation ensures accurate alignment and reliable connection during the final assembly stage, eliminating the need for complex adjustment procedures.
Solution Approach 2:
The patent replaces traditional mechanical joining methods with a form-locking connection system integrated into the insert. This system uses precisely engineered geometric features (positioning elements and anti-rotation elements) that provide automatic alignment and secure attachment, improving both reliability and ease of assembly.
