Mandibular Augmentation Implants With Ligament Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mandibular augmentation procedures are limited by the anatomical features of the chin, particularly the retaining ligaments of the mandible, which constrain the size and placement of chin implants, restricting the extent of augmentation possible.
Innovation Solution
A method involving the surgical manipulation of the left and right anterior mental fibrous condensations and mandibular ligaments to create a subperiosteal implantation cavity, allowing for the insertion of a mandibular implant that extends beyond the attachment sites of these ligaments, combined with novel chin implants designed to augment the jaw area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional mandibular augmentation procedures are used, then the procedure is simple and quick, but the implant size and placement are constrained by retaining ligaments, limiting augmentation effectiveness
Solution Approach 1:
The patent extracts and removes the retaining ligaments from the mandibular region to eliminate their constraining effect on implant placement. By surgically releasing these ligaments, the procedure enables implants to extend beyond the traditional attachment sites, thereby increasing implant size and placement flexibility without compromising the overall simplicity of the surgical approach
Solution Approach 2:
The patent performs preliminary surgical manipulation of the retaining ligaments and soft tissues before implant insertion. This preliminary action involves releasing and repositioning the ligaments to create sufficient space and accessibility for larger implants, allowing the main implantation step to proceed smoothly with enhanced versatility
2Adaptability or versatility
If retaining ligaments are released to allow larger implants, then implant size and placement flexibility improve, but surgical complexity increases
Solution Approach 1:
The surgical procedure is segmented into distinct, manageable steps: (1) incision and exposure, (2) systematic release of retaining ligaments, (3) creation of implantation cavity, and (4) implant insertion. This segmentation allows the complex task of ligament release to be broken down into routine maneuvers that can be performed sequentially with standard surgical instruments, reducing the perceived complexity while achieving enhanced implant versatility
Solution Approach 2:
The patent introduces a subperiosteal cavity as an intermediary space between the mandible and the overlying soft tissues. This cavity serves as a prepared receptacle that accommodates larger implants while organizing the surgical field, making the complex interaction between released ligaments and implant placement more manageable and predictable
3Loss of time
If traditional implant placement is used, then surgical time is reduced, but augmentation volume and aesthetic results are limited
Solution Approach 1:
The patent performs preliminary release and repositioning of the retaining ligaments and soft tissues before implant insertion. This preliminary action creates adequate space for larger implants without requiring excessive surgical time, as the ligament release maneuvers are performed efficiently using standard surgical techniques and instruments
Solution Approach 2:
The patent changes the key parameter of implant size by removing the anatomical constraints (retaining ligaments) that previously limited implant dimensions. By altering the boundary conditions of the surgical field through ligament release, significantly larger implants can be inserted, thereby increasing augmentation volume while the time penalty remains minimal due to the efficiency of the release technique

AI summary
The present specification discloses a method of augmenting or enhancing a chin of an individual comprising excising the left and right anterior mental fibrous condensation anteriorly and elevating the left and right medial mandibular and mandibulocutaneous ligaments to create an extended subperiosteal pocket as well as mandibular implants designed to be implanted using such methods.
