Hydroxylated Dental Implant Abutment for Soft Tissue Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dental implant systems with submerged anchoring parts at bone level face challenges in achieving effective soft tissue integration and sealing, leading to potential inflammation and bone resorption due to bacterial presence on smooth abutment surfaces.
Innovation Solution
The abutment features a soft tissue contact surface that is at least partially hydroxylated or silanated, promoting tissue attachment, with options for surface roughening, hydrophilicity, and specific materials like titanium or zirconia, enhancing integration and reducing autoimmune reactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the abutment surface is kept smooth and unhydroxylated, then manufacturing is simpler and material purity is maintained, but soft tissue integration is poor and plaque accumulation occurs
Solution Approach 1:
The patent applies chemical parameter changes by hydroxylating the abutment surface, transforming it from a smooth unhydroxylated state to a hydroxylated state that promotes soft tissue integration. This chemical modification enables better connective tissue attachment while maintaining manufacturing simplicity.
Solution Approach 2:
The hydroxylated surface is created as a preliminary treatment before the abutment is placed in the mouth. This preliminary chemical preparation ensures that the surface is already optimized for tissue integration at the time of implantation, eliminating the need for complex in-situ treatments.
2Reliability
If the abutment surface is roughened to improve osteointegration, then bone integration is enhanced, but soft tissue sealing is compromised and inflammation increases
Solution Approach 1:
The patent applies different surface characteristics to different regions: the bone contact surface is roughened to enhance osteointegration, while the soft tissue contact surface is kept smooth and hydroxylated to promote tissue integration and sealing. This local differentiation resolves the contradiction between bone integration and inflammation prevention.
Solution Approach 2:
The patent uses chemical parameter changes (hydroxylation) specifically on the soft tissue contact surface to achieve tissue integration without mechanical roughening. This allows the soft tissue area to maintain smoothness for sealing while the bone contact area can be roughened for osteointegration.
3Reliability
If the abutment surface is hydroxylated to promote soft tissue attachment, then connective tissue integration is improved, but the surface becomes more reactive and may trigger autoimmune reactions
Solution Approach 1:
The patent carefully controls the hydroxylation parameter to create a surface that is reactive enough to promote tissue attachment but not so reactive as to trigger autoimmune responses. The hydroxylated surface provides the necessary biological activity for tissue integration while maintaining safety.
Solution Approach 2:
The hydroxylated surface is created as a temporary, reversible modification that facilitates tissue integration during the healing period and then becomes part of the stable implant-tissue interface. The surface chemistry is designed to be biocompatible and non-allergenic, eliminating long-term harmful effects.
