Vibrating Dental Implant Burr for Eccentric Osteotomy Preparation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Eccentric dental implants are difficult to install due to the challenge of preparing eccentric osteotomies, which often require special instrumentation, and improper site preparation can lead to instability and hygienic or aesthetic issues.
Innovation Solution
An apparatus and method for preparing dental implant sites using a burr with a cutting surface and a smooth tip, coupled to a vibrational source, that allows for accurate widening of the osteotomy site without damaging the bottom, combined with an osteotomy seat to prevent direct contact and ensure stable anchoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional drills and screwing techniques are used for concentric implants, then installation is easy, but functional, hygienic, and aesthetic problems occur
Solution Approach 1:
The patent employs asymmetric (eccentric) implant designs that mimic natural tooth root positions and orientations, departing from symmetric concentric implants. This asymmetry allows the implant to better match the functional and aesthetic requirements of natural teeth while maintaining ease of installation through specialized preparation instruments
2Manufacturing precision
If special instrumentation is used for eccentric implants, then eccentric osteotomies can be prepared, but device complexity increases
Solution Approach 1:
The preparation system is segmented into distinct functional components: guide instruments for positioning, tapered reamers for shaping, and specialized burrs for final preparation. Each component performs a specific function in sequence, simplifying the overall complex task of eccentric osteotomy preparation while maintaining high precision
Solution Approach 2:
Guide instruments are used to pre-establish the correct position, angle, and depth of the osteotomy site before actual implant placement. This preliminary action ensures accurate positioning and orientation, reducing the complexity of subsequent preparation steps
3Ease of operation
If the implant site is improperly prepared, then installation is simpler, but implant stability and integration are compromised
Solution Approach 1:
The preparation instruments incorporate features that provide tactile and visual feedback to the operator about osteotomy depth, diameter, and shape. This feedback mechanism ensures the osteotomy is properly prepared to match the implant dimensions, guaranteeing stable integration while maintaining a straightforward installation process
4Ease of operation
If the osteotomy site is made larger or deeper, then implant placement is easier, but sufficient bone mass for anchoring is reduced
Solution Approach 1:
The preparation system removes only the precise amount of bone necessary to accommodate the implant, avoiding excessive removal. Tapered reamers and controlled-depth instruments ensure that the osteotomy is enlarged just enough for implant placement while preserving sufficient bone mass for stable anchoring

Function Achieved in This Case
The solution enables predictably accurate eccentric preparation of the bone, ensuring sufficient jawbone for stable anchoring and minimizing damage to the osteotomy site, thereby improving the installation of eccentric implants.
