Magnesium-Enriched Ceramic Dental Implant Surface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ceramic dental implants face limitations due to low fatigue stability and inadequate osteointegration, which hinders rapid and stable bonding with bone tissue, prolonging healing times.
Innovation Solution
A ceramic body with a surface region enriched in magnesium, forming a hydrophilic surface area, integrated into the material through diffusion of magnesium ions or magnesium oxide, combined with surface roughening and thermal treatment, enhances osteointegrative properties and hydrophilicity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If ceramic material is used for dental implants, then aesthetic appearance is improved, but osteointegrative properties deteriorate
Solution Approach 1:
The patent applies local quality by creating a surface region with different chemical composition than the bulk material. The surface is enriched with magnesium component (at least 1 at.% Mg) through selective diffusion or deposition, while the core zirconia material remains unchanged. This localized modification improves osteointegration and hydrophilicity without affecting the aesthetic properties of the overall ceramic implant.
Solution Approach 2:
The patent creates a composite structure where a magnesium-containing surface layer is combined with the zirconia base material. This composite approach allows the implant to exhibit both the aesthetic and mechanical properties of zirconia and the osteointegrative properties of magnesium-rich surfaces, effectively resolving the contradiction between appearance and biological performance.
2Reliability
If surface roughening and etching are applied, then osteointegration is improved, but surface stability deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-enriching the surface with magnesium component before the implant is placed in the body. This pre-treatment creates a stable, osteointegrative surface layer that is already optimized for bone bonding, eliminating the need for post-implantation surface modifications that could compromise stability.
Solution Approach 2:
The patent changes the chemical composition parameter of the surface by introducing magnesium enrichment (at least 1 at.% Mg in the surface region). This compositional change fundamentally alters the surface properties to enhance osteointegration while maintaining structural stability, as the magnesium is integrated into the zirconia lattice or forms a stable surface compound.
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
The approach results in improved osteointegrative properties and hydrophilicity, facilitating quicker and more stable bone integration, reducing healing time and inflammation risk, while maintaining mechanical properties and visual appearance.
Implementation Method 1
The surface region is enriched with a magnesium component... the enrichment in the magnesium component is in general achieved by incorporation of the magnesium component into the ceramic body due to diffusion or permeation
Implementation Method 2
thermally treating the basic ceramic body with the magnesium compound applied thereon at a temperature higher than 200°C, whereby a magnesium component based on the magnesium compound diffuses into the ceramic material
