Opal-Polymer Composite for Dental Mobility Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dental mobility and weak implant integration due to cell deficits around the root, leading to discomfort, reduced life expectancy, and inefficient surgical techniques, are not adequately addressed by current methods, which also fail to prevent gingival destruction and bacterial accumulation.
Innovation Solution
A composition of synthetic or natural opal incorporated into easily fusible polymers, such as polyethylene or polypropylene, in the form of cylindrical fibers or tapes is introduced into the dental canal to facilitate cell migration and stabilize the tooth or implant by enhancing the extracellular matrix and ligament reconstruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional surgical techniques are used to address dental mobility, then the procedure can be performed with standard materials, but the results are poor and unsatisfactory with high complexity and difficulty
Solution Approach 1:
The invention uses a composite material combining opal particles with dental filling materials (composite resins, glass ionomers, or zinc phosphate cements). The opal particles are incorporated into these materials at concentrations of 0.1-10 mg per mL of filling material, creating a composite that accelerates cell migration while maintaining the structural and bonding properties of the base material. This composite approach resolves the contradiction by providing both effective treatment results and ease of application through standard dental materials.
2Reliability
If the dental canal is filled with powder form opal, then cell migration can be accelerated, but the handling is difficult and the powder flow is uncertain
Solution Approach 1:
The invention changes the physical state parameter of the opal delivery system from dry powder to a viscous composition containing suspended opal particles. This composition is formulated to have optimal viscosity for controlled dispensing through standard dental syringes or cartridges. The opal particles remain suspended in the viscous medium, ensuring uniform distribution and predictable flow characteristics during application, thereby resolving the handling difficulties associated with powder form while maintaining cell migration acceleration efficacy.
3Ease of operation
If opal is introduced as a liquid mixture, then the flow and dosing control become problematic due to rheology issues
Solution Approach 1:
The invention optimizes the viscosity parameter of the opal-containing composition to fall within a specific range that enables both easy flow into the dental canal and precise dosing control. The viscous composition maintains suspension of opal particles without requiring complex rheological modifications, allowing standard dental delivery systems to achieve accurate dose placement. This viscosity optimization resolves the contradiction between flow ease and dosing precision.
4Object-affected harmful factors
If the dental canal is completely filled to obstruct food retention, then bacterial accumulation is reduced, but the nerve injury from tooth mobility cannot be reversed
Solution Approach 1:
The invention applies preliminary action by accelerating cell migration and extracellular matrix formation at the root surface before irreversible nerve damage occurs. The opal-containing material is placed in the dental canal to stimulate rapid cellular response and tissue regeneration, creating a protective barrier and strengthening the periodontal ligament attachment. This preliminary cellular reinforcement can prevent or mitigate nerve injury from mobility, while the filling action simultaneously obstructs food retention and reduces bacterial accumulation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach significantly reduces dental mobility by 30-50% in a few weeks, improves occlusion stability, and accelerates cell migration, allowing for better integration of implants and reduced periimplantitis, with the polymer's properties ensuring ease of handling, sterilization, and sealing.
Implementation Method 1
The present invention therefore proposes to solve the problem of dental mobility or of weak implant integration by a method based on the migration of cells from healthy bone to the location of the cell deficit responsible for mobility.
Implementation Method 2
Opal has been shown to accelerate cell migration. (See French patent application n ° 07-04336 filed on 06/18/2007). The applicants have shown that the silicate, the material of the opal, is organized in spheres arranged in a plan. During synthesis in the laboratory, the spheres are sometimes arranged as in the natural state; most often the spheres are associated in the form of agglomerates. These agglomerates of spheres can, under certain conditions, emit a signal which attracts eukaryotic cells.
Implementation Method 3
A composition based on synthetic or natural opal incorporated into an easily fusible polymer in the form of cylindrical fibers or ribbons for use in the cavity root canal of a natural tooth or cavities created by implants in a tooth or implant.
