Magnesium Tenting Device for Vertical Ridge Augmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dental bone grafting procedures for vertical ridge augmentation are costly, time-consuming, and often require additional procedures for removal of non-biodegradable materials, with unpredictable outcomes and adverse tissue reactions due to the use of metallic biomaterials like titanium.
Innovation Solution
Development of biodegradable magnesium-based tenting devices for periosteal and gingival tissue, which provide vertical ridge augmentation by releasing magnesium ions for bone regeneration, reducing the need for bone graft substitutes and barrier membranes, and degrading over time to avoid separate removal procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional metallic biomaterials like titanium are used for tenting devices, then high strength and structural stability are achieved, but non-biodegradability requires separate removal procedures and causes tissue irritation
Solution Approach 1:
The patent changes the material composition from traditional metals to magnesium-based alloys, fundamentally altering the biodegradability parameter while maintaining mechanical strength through alloying elements and controlled microstructure
Solution Approach 2:
The invention uses magnesium-based composite materials that combine the biodegradability of magnesium with the enhanced strength of alloying elements, creating a material that simultaneously achieves both biocompatibility and structural stability
2Reliability
If guided bone regeneration with barrier membranes is performed, then bone regeneration is protected from mechanical insults, but additional procedures for membrane removal are required
Solution Approach 1:
The magnesium-based tenting device provides self-service by naturally degrading and resorbing in the body over time, eliminating the need for separate removal procedures while continuing to protect the bone regeneration site throughout the healing process
Solution Approach 2:
The device is designed to be temporarily discarded by the body's natural resorption processes, where the magnesium material is broken down and absorbed, converting from a permanent implant to a temporary protective structure that is naturally eliminated
3Duration of action of stationary object
If non-biodegradable materials are used, then device longevity and structural integrity are maintained, but separate removal procedures are needed
Solution Approach 1:
The patent transitions from static, permanent materials to dynamic, time-dependent materials that change their properties over time, with the magnesium device progressively degrading from a strong structural support to a resorbed material, matching the temporal needs of bone healing

AI summary
The invention relates to magnesium screws and screw-like devices for dental implant surgery and, more particularly, to magnesium and magnesium-based tenting devices for implementation in periosteal and gingival tissue overlying an alveolar ridge of a mandible or maxilla to provide vertical ridge augmentation, i.e., bone regeneration. The tenting devices may be composed of magnesium in dry form, such as metallic magnesium and salts thereof; or magnesium alloy including magnesium in dry form and at least one alloying element or compound; or magnesium-polymer composite including magnesium in dry form and at least one polymer.
