Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bone implants face limitations in mechanical strength, chemical resistance, biocompatibility, electrochemical activity, and long-term osseointegration due to properties of titanium, alumina, zirconia, and silicate materials, which affect their durability and integration with bone tissue.
Innovation Solution
Development of bone implants made from silicate rock or mineral aggregates with a dense tangled-fibrous or fine-crystalline structure known as 'jade', which offers high strength, low Young's modulus, and excellent biocompatibility, reducing electrochemical activity and enhancing osseointegration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If titanium implants are used, then mechanical strength and osseointegration ability are improved, but electrochemical activity causes complications
Solution Approach 1:
The patent uses bioglass as a resorbable implant material that temporarily provides mechanical support and then dissolves to be replaced by natural bone tissue, eliminating the need for permanent metallic implants with electrochemical issues
Solution Approach 2:
The patent modifies the chemical composition parameters of the implant material by using bioglass with specific ratios of SiO2, P2O5, CaO, and Na2O, which changes the material's properties from metallic to ceramic, reducing electrochemical activity while maintaining biocompatibility
2Strength
If alumina implants are used, then chemical resistance and strength are improved, but biocompatibility and osseointegration are reduced due to high Young's modulus and positive zeta potential
Solution Approach 1:
The patent changes the material composition from alumina to bioglass with specific chemical parameters (SiO2-P2O5-CaO-Na2O), which alters the surface properties and chemical interactions with bone tissue, improving biocompatibility while maintaining strength
Solution Approach 2:
The patent uses composite bioglass material that combines multiple oxides to achieve a balance of mechanical strength, chemical stability, and biocompatibility, creating a material that is neither purely metallic nor purely ceramic
3Reliability
If zirconia ceramics are used, then aesthetic quality and chemical stability are improved, but long-term stability is compromised due to ageing in aqueous environment
Solution Approach 1:
The patent changes the chemical composition from zirconia to bioglass, which modifies the material's resistance to aqueous environment ageing and improves long-term stability in physiological conditions
4Reliability
If silicate bioglass is used, then osseoinductive properties are improved, but mechanical strength and resistance to resorption are reduced
Solution Approach 1:
The patent optimizes the chemical composition parameters of bioglass (SiO2-P2O5-CaO-Na2O ratios) to achieve a balance between osseoinductive properties and mechanical strength, creating a material that is neither too fragile nor too resistant to resorption
