Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies for osseointegrated prosthetic reconstruction, particularly for slanted implants, face biomechanical limitations that lead to increased tension and bone loss due to inadequate passive fitting, with existing solutions being costly and limited in angulation variations.
Innovation Solution
A system of prosthetic components including slanted compensatory copings, converters, and extenders that offer versatile angulation corrections from 0° to 60°, universal coupling capabilities, and extension options, adaptable to various implant types and materials, enhancing biomechanical stability and reducing tension on the fitting platform.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If angled abutments are used to correct implant angulations, then the implant can be fitted at various angles, but the manufacturing cost increases and the number of angulation variations is limited
Solution Approach 1:
The coping is designed with a universal geometry that can accommodate multiple implant angulations (0° to 60°) through a single standardized component. The coping features a spherical seating surface that interfaces with the implant platform and a cylindrical upper portion that receives the abutment, allowing it to function across a wide range of angles without requiring custom-manufactured angled abutments for each specific angle.
2Object-affected harmful factors
If slanted implants are used to minimize radical surgery, then bone grafting is reduced, but biomechanical limitations cause increased tension and bone loss due to inadequate passive fitting
Solution Approach 1:
The coping introduces geometric parameter changes through its spherical seating surface and angled configuration. The sphere radius (R1) and the angle between the sphere center axis and the coping axis (α) are specifically designed to accommodate slanted implant positions while maintaining proper biomechanical alignment. This allows the prosthesis to adapt to the implant's angulation and achieve passive fitting, distributing occlusal loads evenly and preventing excessive tension on the implant-bone interface.
3Ease of operation
If conventional abutment fitting methods are used on slanted implants, then the procedure is simplified, but occlusal stability decreases and tension concentrates on the fitting platform and screws
Solution Approach 1:
The coping serves as an intermediary component between the slanted implant and the abutment. It features a lower portion with a spherical seating surface that interfaces with the implant platform and an upper cylindrical portion that receives the abutment. This intermediate element translates the implant's angulation into proper alignment for the abutment, maintaining occlusal stability and distributing forces evenly throughout the implant-abutment-coping assembly while preserving procedural simplicity.

AI summary
The present invention refers to a system of prosthetic components consisting of Compensatory Slanted Copings and Abutments of Universal Coupling that function as a set of coupled parts that allow corrections of slants that vary between OQ and 60Q, of fixing osseointeg rated implants, including zygomatic fixations, and it provides a cap, molding transferer and screws for fastening and locking. This system of copings and abutments provides properties of conversion and extension of the implants. Its shape provides better occlusal stability and favorable biomechanics, since the forces are better distributed, diminishing the concentration of tension on the fitting platform of the implant, as well as the screws. The abutments of the universal coupling can be readjusted and be cemented or screwed. In the present system, the superior platform of the coping and the inferior base of the abutment are universalized, since the inferior platform of the coping corrects the slant of the implant. It has screws for fastening and for locking of the coping/abutment set. The characteristics of this system provide great versatility, which allows it to be used in various areas of medicine.
