Dental Implant Surgical Guides With Adjustable Stop-Ring Depth Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current guided surgery protocols in dental implantology are limited to placing implants exclusively at bone level, requiring multiple milling tools for implants with different heights and diameters, and lack flexibility in implant positioning.
Innovation Solution
A method for manufacturing a splint or surgical guide that allows implants to be positioned at various levels, including below or above bone level, using a single milling tool by incorporating stop rings and carriers with adjustable lengths, enabling precise implant placement through a computer-generated virtual surgical plan.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If current guided surgery protocols are used to place implants exclusively at bone level, then surgical precision is maintained, but implant positioning flexibility is limited
Solution Approach 1:
The surgical guide is designed with dynamic adjustment capability through the stop ring mechanism. The stop ring can be positioned at different distances from the reference surface along the guide's longitudinal axis, allowing the guide to adapt to implants at various levels (above, at, or below bone level) while maintaining precise control over drilling depth and implant placement through the carrier-stop ring interaction
2Manufacturing precision
If multiple milling tools are used for implants with different heights and diameters, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The surgical guide incorporates a universal carrier system that can accommodate implants of different heights and diameters. The carrier includes a reception cavity that can hold various milling tools and implants, with the stop ring mechanism providing universal depth control for all implant types. This allows a single guide design to serve multiple implant placement scenarios without requiring multiple specialized guides
3Device complexity
If a single milling tool is used for implants with varying heights, then device complexity is reduced, but manufacturing precision deteriorates
Solution Approach 1:
The stop ring acts as an intermediary element between the carrier and the implant placement process. It provides a reference surface that the carrier engages with to control drilling depth and implant positioning. This intermediary mechanism enables precise depth control for implants of varying heights using a single milling tool, as the stop ring-c carrier interaction compensates for the tool's fixed length

AI summary
A method for manufacturing a splint or surgical guide for the implantation of at least one dental implant, relating to a part of a guided oral surgery process by which at least one implant is placed or implanted in a patient's jaw to replace the function of one or more natural teeth. The manufacturing method is implemented by a computer program. The object is to improve the implant placement process in an optimal and minimally invasive, as well as more simplified way.
