Variable Profile Dental Implant Thread for Bone Density Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dental implants face challenges in achieving stability in low-density bone while maintaining ease of insertion and preventing slipping into regions with lower bone density, requiring multiple types of implants for different bone densities and complicating stock management and usage.
Innovation Solution
A dental implant with a variable profile thread and tapered core, featuring a coronal region with different tapering aspects and micro-threads, allowing for enhanced stability in low-density bone while being easily insertable and usable in both low and high-density bone, with a design that prevents slipping through its apical threads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the implant is designed to be more condensing to enhance stability in low-density bone, then stability is improved, but insertion becomes more difficult and the implant has a stronger tendency to slip into regions with lowest bone density
Solution Approach 1:
The implant applies local quality by having different thread characteristics at different locations: apical threads are designed with higher condensing capability to enhance stability in low-density bone, while coronal threads have lower condensing capability to facilitate easier insertion and prevent slipping. This spatial differentiation of thread properties allows the implant to simultaneously achieve both stability and ease of operation.
Solution Approach 2:
The implant is segmented into multiple thread regions along its length, with each segment having distinct condensing characteristics. The apical portion features high-condensing threads for stability, while the coronal portion features low-condensing threads for ease of insertion. This segmentation allows different parts of the implant to perform specialized functions that resolve the contradiction between stability and ease of operation.
2Reliability
If the implant is designed to be more condensing to enhance stability in low-density bone, then stability is improved, but the implant has a stronger tendency to slip towards regions with low bone density
Solution Approach 1:
The implant uses local quality by varying thread condensing characteristics along its length: apical threads provide strong condensing action to prevent slipping into low-density regions, while coronal threads provide gentler engagement to maintain precise insertion positioning. This localized differentiation resolves the conflict between preventing slip and maintaining insertion precision.
3Adaptability or versatility
If multiple types of implants are used for different bone densities, then suitability for specific bone types is improved, but device complexity and stock management become more complicated
Solution Approach 1:
The implant achieves universality by incorporating multiple thread types along its single structure, enabling it to function effectively in both low-density and high-density bone. This multi-functional design allows one implant to replace multiple specialized implants, reducing device complexity and stock management requirements while maintaining adaptability to different bone types.
Solution Approach 2:
The implant merges previously separate implant designs into a single unified structure that combines both high-condensing and low-condensing thread characteristics. By integrating multiple functional elements into one implant, the design eliminates the need for separate implants for different bone densities, thereby reducing complexity while preserving versatility.

AI summary
A dental implant that facilitate insertion and can be used in all bone types. The implant includes a body having a coronal end, and an apical end opposite the coronal end. A tapered region may be adjacent the apical end. On the apical part one or more taps are provided so the tap is cutting when rotating clockwise and counter-clockwise. The implant can have at least one variable profile helical thread that extends along the tapered region. The implant can have also micro-threads below the main threads, a gradual compressing tapered core, a self drilling apical end and a narrow coronal region.
