Direction-Guided False Tooth Implant for Alveolar Ridge Widening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing false tooth implanting devices face issues such as bone fragments left in the implant hole, potential cracking of the alveolar ridge due to uneven engagement of the implant, and difficulty in aligning and securing the implant correctly, leading to instability and increased risk of inflammation and pain.
Innovation Solution
The proposed false tooth implanting device includes a main implant body with an installation direction indicator, a lower block, and a vertical screw. The device allows for easy alignment and secure fixation by providing a guide structure and a vertical securing screw, ensuring the widening effect is directed correctly along the alveolar ridge, thus preventing unnecessary trauma and enhancing stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a screw-threaded false tooth implant is used to fix the implant to the alveolar bone, then the implant can be securely fixed, but bone fragments are left in the implant hole which can decay and induce swelling and inflammation
Solution Approach 1:
The implant device is divided into separate components: a main implant body and a lower block that can be independently positioned and secured. This segmentation allows the lower block to be precisely placed to prevent bone fragment displacement without compromising the overall fixation security provided by the main implant body's screw threads.
Solution Approach 2:
The lower block acts as an intermediary component between the main implant body and the alveolar bone. It serves as a protective barrier that prevents bone fragments from being displaced into the implant hole while allowing the screw-threaded fixation mechanism to function effectively for secure attachment.
2Reliability
If the outer threads of the implant are engaged with the surrounding alveolar bone, then the implant can be fixed, but the varying thickness of the alveolar ridge can cause cracking and deep injuries
Solution Approach 1:
The lower block provides localized reinforcement at the critical interface between the implant and the alveolar bone. This local quality enhancement distributes the engagement forces more evenly across the alveolar ridge, preventing stress concentration that would cause cracking, while maintaining the overall fixation provided by the outer thread engagement.
3Manufacturing precision
If the lower protruding block is nested into the hole formed in the alveolar bone, then the widening effect is achieved, but the block becomes completely hidden and the dentist cannot determine the correct direction for rotation
Solution Approach 1:
The lower block is provided with a color indicator that changes or becomes visible when the block is in the correct position and orientation. This color change mechanism allows the dentist to visually detect whether the block has been properly positioned and rotated to the correct direction, eliminating the problem of the block being completely hidden nested in the alveolar bone hole.
4Reliability
If a lateral screw is used to expand and press the upper portion of the main implant body, then stable connection is achieved, but the operating space is very limited and alignment is difficult
Solution Approach 1:
Instead of using a lateral screw that requires precise alignment from the side, the invention inverts the approach by using a vertical screw that can be easily inserted from the top. This inversion of the screw insertion direction provides ample operating space and eliminates the alignment difficulties associated with lateral screw holes, while still achieving the necessary expansion and stable connection through the vertical screw mechanism.
