Depth Adjustable Surgical Pin for Dental Implant Template Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical pins fail to accurately control the depth, position, and pressure of surgical templates against organic substrates during dental implant procedures, leading to potential misalignment and slippage.
Innovation Solution
A depth adjustable surgical pin featuring a housing that integrates into a drill guide aperture and a retention rod with a threaded section, allowing for precise adjustment and locking of the template's depth, position, and pressure through rotational engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing surgical pins are used to retain surgical templates, then the template can be anchored into place, but the depth, position, and pressure of the template cannot be precisely controlled
Solution Approach 1:
The retention rod is nested within the housing, with the rod extending through the housing and engaging with threaded internal structures. This nested configuration allows the retention mechanism to be compact while maintaining adjustable depth control through rotational engagement of the rod with the housing.
Solution Approach 2:
The retention rod is designed to be rotatable within the housing, allowing dynamic adjustment of the template's depth, position, and pressure. The rotational movement engages threaded portions of the rod with corresponding threads in the housing, enabling precise control of the template's placement parameters.
2Reliability
If existing surgical pins are used to retain surgical templates, then the template can be anchored, but misalignment and slippage occur during surgery
Solution Approach 1:
The housing is configured with predetermined depth markings and alignment features that guide the retention rod to the correct position before final tightening. This preliminary positioning ensures proper alignment and prevents slippage during the surgical procedure.
Solution Approach 2:
The threaded engagement between the retention rod and housing provides mechanical feedback through resistance and locking forces, ensuring the template remains securely positioned at the desired depth and orientation throughout the surgical procedure.

AI summary
A depth adjustable surgical pin retains a surgical template at a desired depth, vertical and horizontal position, and pressure against an organic substrate. The surgical pin provides a housing and a retention rod that work in conjunction to achieve this retention function. The housing is defined by a mount end, rod end, inner sidewall having a female thread, and an outer sidewall having ridges for adhering to a drill guide aperture of the surgical template. The housing sets at a predetermined depth in the drill guide aperture. The retention rod comprises a proximal end having a cap, distal end tapering to a sharp point, and a male thread that threadably engages the housing. The retention rod serves as an anchor and provides added strength to the surgical template. The housing becomes an integral part of the surgical guide template to guide the retention rod into a locking position.
