Zirconium Dioxide Guided Bone Regeneration Device for Defect Reconstruction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current guided bone regeneration techniques face challenges in achieving optimal bone reconstruction and symmetry, particularly with resorbable membranes that may interfere with bone regeneration and require additional interventions for removal, while non-resorbable membranes can cause tissue irritation and require a second surgery for removal.
Innovation Solution
A guided bone regeneration device made from zirconium dioxide with a three-dimensional shape, manufactured using techniques like 3D printing, that covers the bone defect, allowing for vertical and horizontal augmentation, and includes microperforations for improved angiogenesis and biomaterial access, and a removable design for easy extraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If resorbable membranes are used for guided bone regeneration, then the need for removal surgery is eliminated, but the membranes may interfere with bone regeneration and require additional support materials
Solution Approach 1:
The patent extracts the membrane function from the support structure, using a resorbable membrane alone without additional support materials. The membrane is designed to provide both structural support and biological function, eliminating the need for separate support elements while maintaining regeneration effectiveness.
Solution Approach 2:
The patent modifies the physical and chemical parameters of the resorbable membrane, specifically its porosity and mechanical strength, to ensure it provides adequate support during bone regeneration while maintaining its resorbable nature. The membrane's degradation rate is controlled to match bone formation rate.
2Stability of the object's composition
If non-resorbable membranes are used for guided bone regeneration, then structural stability is maintained, but tissue irritation occurs and removal surgery is required
Solution Approach 1:
The patent employs a resorbable membrane that serves its structural support function temporarily during bone regeneration, then degrades and is eliminated by the body. This disposable approach avoids long-term tissue irritation while providing necessary structural stability during the critical regeneration period.
Solution Approach 2:
The membrane is designed to be discarded by the body's natural resorption processes after fulfilling its support function. The controlled degradation allows the membrane to be recovered by metabolic processes, eliminating the need for surgical removal and avoiding chronic tissue irritation.
3Reliability
If conventional membrane techniques are used, then bone regeneration is attempted, but optimal modeling and symmetry of bone structure are difficult to achieve
Solution Approach 1:
The patent creates a custom-shaped membrane that copies the precise geometry of the bone defect and desired regeneration outcome. Using imaging data, the membrane is fabricated to match the specific anatomical requirements, ensuring optimal modeling and symmetry of the regenerated bone structure.
Solution Approach 2:
The patent employs asymmetric membrane designs that are specifically tailored to match the unique geometry of each bone defect. Rather than using symmetric or standardized shapes, the membrane is customized to accommodate the asymmetric nature of actual bone defects, improving both fit and regeneration outcome.
