Bone Material Dental Support Screw for Grafting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dental implantable screws, often made of metals or other materials, can irritate tissues, require separate removal, and may not maintain shape under pressure during bone grafting procedures, leading to complications like tissue disruption and bone deformation.
Innovation Solution
Development of implantable screws formed from bone material or artificial bone material with a contoured head and threaded shaft, which can become integral with the newly formed alveolar ridge, reducing the need for removal and minimizing tissue irritation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional metal screws are used for space maintenance during bone grafting, then the screws provide structural support and maintain space, but they can irritate tissues, shed harmful ions, and require separate removal procedures
Solution Approach 1:
The patent changes the material parameter of the screw from metal to bone material (allograft or autograft), fundamentally altering the biocompatibility and integration properties while maintaining the structural support function
Solution Approach 2:
The bone material screw is designed to be naturally absorbed and replaced by the patient's own bone over time, eliminating the need for separate removal procedures and avoiding long-term foreign body presence
2Strength
If conventional metal screws are used for space maintenance during bone grafting, then the screws provide structural support, but they require separate removal operations which cause tissue disruption and expose new bone
Solution Approach 1:
The bone material screw is designed to be naturally absorbed and replaced by the patient's own bone over time, eliminating the need for separate removal procedures and avoiding long-term foreign body presence
Solution Approach 2:
The bone material screw performs self-removal through natural biological processes, where the patient's body gradually absorbs the allograft material and replaces it with native bone, eliminating the need for surgical intervention
3Shape
If conventional membranes are used during bone grafting, then the membranes cover the bone graft, but they do not maintain their shape and deform when experiencing pressure from chewing
Solution Approach 1:
The patent combines the membrane with a rigid support screw structure, creating a composite system where the rigid screw provides shape stability while the membrane provides biological coverage and containment
Solution Approach 2:
The support screw acts as an intermediary structural element between the bone graft and the membrane, providing mechanical support that allows the membrane to maintain its shape and position during the bone healing process
4Shape
If titanium mesh fixtures are used to contain bone graft material, then the fixtures provide containment, but they are foreign bodies that must be removed after bone augmentation
Solution Approach 1:
The patent changes the material parameter from titanium mesh to bone material (allograft or autograft), transforming the containment structure from a permanent foreign body to a biodegradable scaffold that integrates with and is replaced by native bone
Solution Approach 2:
The bone material screw is designed to be naturally absorbed and replaced by the patient's own bone over time, eliminating the need for separate removal procedures and avoiding long-term foreign body presence

AI summary
An implantable screw for maintaining horizontal and/or vertical space during bone grafting procedures. The screw includes a head having a top surface configured to engage a dental membrane, a shaft, and a tip. The shaft is at least partially threaded to engage bone. The dental membrane and the screw provide space for bone growth material during bone grafting.
