Segmented Dental Implant Template with Open Guide Bore Ring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dental implant templates face challenges in providing a single-step solution without the need for extensive reworking, particularly due to the absence of undercuts, which can cause the template to become stuck during use.
Innovation Solution
A surgical template design featuring a guide bore ring with a side opening for drill insertion, a resilient clipping mechanism, and a snake-like rail structure that avoids undercuts, allowing for secure placement and easy access during drilling without jamming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a traditional dental implant template is designed with closed structures for secure placement, then the template stability is improved, but the template may become stuck or jammed during drilling operations
Solution Approach 1:
The template is divided into multiple independent rails (first rail, second rail) that are separately positioned on adjacent teeth. Each rail can be independently secured to its tooth, allowing the template to be stable while maintaining open access for drilling through the guide bore ring.
Solution Approach 2:
The template transitions from a closed, enclosed structure to an open framework structure with multiple rails positioned in different spatial locations. This dimensional redistribution allows drilling access through the guide bore ring while maintaining stability through distributed tooth contacts.
2Device complexity
If a single-rail template structure is used, then the device complexity is reduced, but the template cannot provide sufficient support and positioning for multiple teeth
Solution Approach 1:
Each rail serves multiple functions: it provides structural support, positions the template on a specific tooth, and contributes to the overall stability of the template system. The guide bore ring similarly serves as both a structural connector and a drilling guide.
Solution Approach 2:
Multiple rails and the guide bore ring are merged into a single integrated template structure that functions as a unified system. The rails are connected through the guide bore ring, creating a combined structure that distributes support across multiple teeth while maintaining operational simplicity.
3Measurement precision
If the template is designed to fit tightly on teeth for precise positioning, then the positioning precision is improved, but the template may become difficult to remove or adjust
Solution Approach 1:
The template contacts each tooth through separate, discrete rails rather than a continuous enclosing structure. This segmentation allows each rail to be independently positioned for precision while enabling easy removal or adjustment of individual rails if needed.
Solution Approach 2:
The template design extracts the essential positioning function from a continuous enclosing structure and implements it through discrete contact points on individual rails. This extraction maintains positioning precision while eliminating the constraint of a closed structure that would hinder adjustment.

AI summary
A surgical template (10) comprising one a drill guide bore (70) surrounded by a guide bore ring (71), which comprises an inner rail (20) and an outer rail (30) with an interspace (60) in between. At least three inner and three outer connecting points (81, 82) are provided on the inner and outer rail (20, 30) which are adapted to be positioned on portions of the teeth of the patient to define the three dimensional position and orientation of a drill guide bore ring (71). The rails (20 and 30) are provided in a predetermined varying distance one from the other allowing accommodation of the inner and outer connecting points (81 and 82) on the rails (20, 30), wherein the template (10) further comprises at least two connecting webs (40) connecting the inner rail (20) and the outer rail (30) in a predetermined distance one from the other.
