Tooth Implant Indexing for Precise Component Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tooth replacement systems face challenges in accurately positioning auxiliary components and secondary parts due to irregular jaw bone growth around implants, leading to difficulties in impression-taking and increased reject rates of pre-manufactured dental parts.
Innovation Solution
A tooth implant with a receiving opening featuring an inner polygon and indexing mechanism that reproduces the geometry and angular position of the inner polygon, facilitating precise alignment and positioning of auxiliary components and secondary parts, and an internal thread for secure fastening and drainage, allowing for tension-free impression-taking even in inclined positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the implant relies on natural jaw bone growth to position auxiliary components, then the treatment follows natural healing processes, but the positioning precision deteriorates due to irregular bone growth patterns
Solution Approach 1:
The patent applies the copying principle by creating an indexing structure on the implant that replicates the inner polygon geometry. This indexing serves as a precise geometric copy that can be transferred to auxiliary components and secondary parts, ensuring accurate positioning regardless of irregular jaw bone growth patterns. The indexing captures the essential geometric information needed for precise reproduction of component positions.
Solution Approach 2:
The patent implements preliminary action by pre-defining the geometric structure (inner polygon with indexing) on the implant before the healing process begins. This pre-established geometric framework guides the positioning of auxiliary components and secondary parts, ensuring that even though bone growth is irregular, the components are positioned according to the predetermined indexing geometry, thereby maintaining precision throughout the treatment process.
2Device complexity
If the implant uses a simple cylindrical fit without indexing, then the device complexity is reduced, but the positioning precision of auxiliary components deteriorates
Solution Approach 1:
The patent applies asymmetry by introducing a non-circular inner polygon geometry with specific indexing features into the otherwise simple cylindrical implant structure. This asymmetric geometric pattern provides unique positioning information that prevents rotational ambiguity and ensures precise orientation of auxiliary components. The asymmetric indexing features (such as flat surfaces or notches at specific angles) create a unique geometric signature that guides precise component placement without requiring complex overall implant redesign.
3Adaptability or versatility
If the implant is placed in an inclined position to accommodate anatomical constraints, then the adaptability to patient anatomy is improved, but the precision of impression-taking deteriorates due to angular divergences
Solution Approach 1:
The asymmetric indexing geometry provides a reference framework that remains valid regardless of the implant's angular orientation in the jaw. The indexed positions are defined relative to the implant body, allowing precise positioning of components even when the implant itself is inclined to accommodate anatomical constraints. The asymmetric features create a unique angular signature that can be accurately reproduced in the impression, preserving precision despite inclined placement.
