Dental Implant Guide with Snap-Stop Depth Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dental implant kits face challenges in accurately achieving the desired implantation depth, leading to potential damage from over-insertion or failure to secure prosthetics due to the need for simultaneous movement and pressure on a blocking element during implantation.
Innovation Solution
A kit comprising a template with an implantation channel, an implant guide with a cylindrical body, and a stop element that automatically snaps into a groove at the desired depth, providing a clear auditory and tactile signal to prevent further insertion, ensuring precise depth placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a blocking element is used to control implantation depth, then depth control is improved, but the operation becomes more complex requiring simultaneous movement and pressure application
Solution Approach 1:
The stop element automatically engages with the implant guide at the predetermined depth without requiring manual intervention. The element self-activates through the natural implantation movement, releasing from its holding position and engaging the depth stop feature, thereby eliminating the need for simultaneous pressure application by the operator
Solution Approach 2:
The stop element acts as an intermediary mechanism between the implant guide and the template. It translates the continuous implantation movement into a discrete depth control action by automatically engaging and disengaging from the implant guide at the predetermined depth, simplifying the operator's task while maintaining precise depth control
2Adaptability or versatility
If a detachable stop element is used, then adaptability is improved, but reliability may worsen due to potential loss or misplacement
Solution Approach 1:
The stop element is designed as a detachable, extractable component that can be removed from the template and implant guide system. This allows for easy adjustment of depth settings and replacement if needed, while the element's design ensures it can be reliably reattached when required
Solution Approach 2:
The stop element transitions between two states: held in a fixed position during normal operation, and freely movable when released. This dynamic behavior allows the element to be securely retained during implantation while enabling easy removal and repositioning for different depth requirements, balancing reliability with adaptability

AI summary
The present invention provides a kit for use for the implantation of a dental implant, comprising an implant guide comprising a proximal end and a distal end, wherein the distal end is configured to be detachably attached to a dental implant, said implant guide comprising a cylindrical body, wherein the cylindrical body comprises a cylindrical outer surface and a circumferential groove in the outer surface, and a template configured to be arranged at a predetermined location with respect to a jaw, wherein the template comprises at least one implantation channel to guide the cylindrical body of the implant guide in a desired implantation direction during implantation of a dental implant in the jaw, and a stop surface at an end of the implantation channel. The kit comprises a stop element comprising a first part and a second part, wherein the first part and the second part are configured to be movable between a first state, in which the first part and the second part are spaced at a first distance, and a second state, in which the first part and the second part are spaced at a second distance, wherein the first distance is smaller than the second distance, and wherein the first and second parts are biased to the first state, wherein the second distance is the same or larger than a distance between diametrically opposite sides of the outer surface of the implant guide, such that, before implantation, the first part and the second part can be arranged, in the second state, on diametrically opposite sides of the outer surface, and that during movement in the implantation direction of the dental implant into the jaw, the stop surface of the implantation channel will push the stop element towards the groove until the groove will allow the first and second part to move towards the first state and the stop element will be caught by the groove, therewith blocking further movement of the implant guide in the implantation direction.
