Dental Implant Template Recess Blocking Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dental implant placement techniques face challenges in accurately achieving the desired position, orientation, and depth due to template deformation during screwing, leading to inaccuracies in implant positioning and subsequent prosthetic attachment.
Innovation Solution
A template with a recess that opens partly on the surface and partly in the bore, allowing a blocking element to detect when the implant guide reaches the desired depth, preventing template deformation and ensuring precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the implant guide is fixed in the template and the implant is screwed in the jaw, then the implant can be positioned in the jaw, but the template becomes deformed when the collar makes contact with the stop, causing the implant to be screwed too deep
Solution Approach 1:
A blocking element is introduced as an intermediary component between the implant guide and the template. This blocking element can be inserted into the recess in the template and engages with the implant guide to prevent it from moving beyond the desired depth position. The blocking element acts as a mediator that stops the implant guide at the correct position without requiring the collar to contact the stop, thereby preventing template deformation while maintaining accurate depth control.
2Stability of the object's composition
If the implant is provided not deep enough to avoid template deformation, then the template remains stable, but the implant will not be positioned correctly in relation to other implants
Solution Approach 1:
The blocking element serves as a mediator that enables the implant to reach the correct depth without causing template deformation. By inserting the blocking element into the recess, it engages with the implant guide to provide a mechanical stop at the precise desired depth position. This allows the implant to be positioned accurately in relation to other implants while the template remains stable and undeformed, as the blocking element bears the stopping function rather than the template structure itself.
3Ease of operation
If visual detection with the naked eye is used to establish when the collar makes contact with the stop, then the process can be monitored, but the implant is nevertheless provided too deeply or not deeply enough
Solution Approach 1:
The blocking element introduces a tactile and mechanical feedback mechanism that supplements visual detection. When the blocking element engages with the implant guide at the desired depth, it creates a distinct mechanical sensation and positional reference that is more precise than visual detection alone. This intermediary component provides a reliable physical stop that can be detected both visually and tactilely, eliminating the inaccuracy of relying solely on naked-eye visual detection of collar-stop contact.
Solution Approach 2:
The blocking element provides immediate mechanical feedback when the desired depth is reached. As the implant guide is advanced, the blocking element moves within the recess until it engages with a feature on the implant guide, creating a clear tactile and positional signal that the correct depth has been achieved. This feedback mechanism is more reliable and precise than visual detection alone, as it provides both visual and tactile confirmation of the correct position, eliminating the measurement inaccuracies associated with visual detection.
