Modular Dental Implant Segmentation for Length Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dental implants are not adaptable to changing clinical requirements, limiting their ability to be extended or shortened, which affects the quality of dental restoration and can cause harm to the periodontal supporting structure.
Innovation Solution
A modular dental implant system comprising multiple segments that can be connected and disconnected to achieve desired lengths, including an abutment, implant body segments, and an implant apex or neck, allowing for customization during implantation and extraction using a specialized extraction kit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional fixed-length dental implants are used, then the implant structure is simple, but the implant cannot be adjusted to changing clinical requirements
Solution Approach 1:
The dental implant is divided into multiple separable body segments that can be connected in sequence. Each segment has a standardized interface allowing them to be assembled into different total lengths, enabling adjustment to varying clinical requirements while maintaining a relatively simple individual segment design.
2Adaptability or versatility
If multiple fixed-size implant varieties are prepared, then all clinical requirements can be met, but the inventory complexity and selection difficulty increase
Solution Approach 1:
A universal implant body segment design is implemented where multiple segments of the same type can be connected through standardized interfaces. This allows a limited set of segment types to create multiple final implant lengths, replacing the need for many different fixed-length implant varieties while maintaining comprehensive clinical coverage.
3Ease of repair
If non-modular implants are used, then the implant structure is simple, but extraction and adjustment are difficult or impossible
Solution Approach 1:
The implant is designed with separable body segments connected through standardized mechanical interfaces. This segmentation allows individual segments to be easily added, removed, or exchanged during treatment, significantly improving ease of adjustment and extraction compared to fixed non-modular designs while using relatively simple connection mechanisms.

AI summary
A method provides a modular dental implant. The modular dental implant has (a) an implant apex comprising an internal fastening surface; (b) a first hollow implant body segment; (c) an abutment having a screw access hole; and (d) a fastening screw. The method also entails fastening the external fastening surface of the first hollow implant body segment to the internal fastening surface of the implant apex; and screwing the fastening screw (i) through the abutment and the first hollow implant body segment, and (ii) into the implant apex, when the abutment, the first hollow implant body segment, and the implant apex are fastened together.
