Dental Intermediate Pillar for Immediate Implant Site Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dental implant protocols are invasive and require multiple interventions, leading to prolonged treatment duration and increased operational risks due to the need for separate tooth extraction and implant placement surgeries, as well as tissue resorption and pain from invasive surgical manipulations.
Innovation Solution
A peri-implant healing device, specifically a dental intermediate pillar with a lower part for insertion into a dental implant, an intermediate part for anatomically shaped closure, and an upper part for fixing a prosthetic element, allowing customizable closure and reducing the number of interventions by stabilizing the surgical site and supporting bone regeneration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate tooth extraction and implant placement surgeries are performed to allow bone site regeneration, then bone healing and gingival closure are improved, but treatment duration is extended and operational risks are increased
Solution Approach 1:
The patent combines tooth extraction and implant placement into a single surgical intervention by using an extraction socket bridge that integrates the implant with the extraction site. This merging of procedures eliminates the need for separate surgeries spaced months apart, reducing treatment duration while maintaining bone healing quality through the bridge's protective coverage of the extraction socket.
Solution Approach 2:
The extraction socket bridge is designed with pre-formed anatomical shapes that anticipate the needed bone regeneration and soft tissue closure. The bridge provides immediate structural support and protection after extraction, preparing the site for osseointegration without requiring delayed implant placement, thus accelerating the overall treatment timeline.
2Reliability
If multiple interventions are performed on the gum after implant placement, then proper healing and closure are achieved, but invasiveness of treatment increases and post-operative consequences are amplified
Solution Approach 1:
The patent combines multiple healing interventions into a single integrated structure - the extraction socket bridge simultaneously serves as the implant support, the extraction site protector, and the soft tissue closure guide. This eliminates the need for multiple separate surgical interventions to achieve proper healing, thereby reducing post-operative risks while maintaining healing quality.
Solution Approach 2:
The extraction socket bridge acts as an intermediary structure that mediates between the implant and the soft tissue. It provides a stable interface that guides gingival closure and protects the underlying bone and implant, reducing the need for additional surgical manipulations and minimizing post-operative complications.
3Reliability
If anatomically shaped closure elements are fixed to the intermediate pillar, then gingival closure and bone regeneration are improved, but device complexity increases
Solution Approach 1:
The patent merges the intermediate pillar with the anatomically shaped closure element into a single integrated component. The closure element is directly formed as part of the pillar structure, eliminating the need for separate fixation mechanisms and reducing overall device complexity while maintaining effective gingival closure and bone regeneration capabilities.
Solution Approach 2:
The intermediate pillar is designed with multi-functionality, serving both as the structural support for the implant and as the anchor for the anatomically shaped closure element. This universal design allows a single component to perform multiple functions, reducing the number of separate parts needed and simplifying the overall device structure.
