Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current implant guides in dentistry often lack sufficient mechanical strength and uniform physical properties, leading to issues such as bleeding, swelling, infection, dislodgement, and nerve damage during dental implant procedures, due to non-uniform properties and cytotoxicity.
Innovation Solution
A 3D printing resin composition incorporating bisphenol A-glycidyl methacrylate (BIS-GMA), ethoxylated bisphenol A dimethacrylate (BIS-EMA), urethane dimethacrylate (UDMA), a photoinitiator, additive, filler, viscosity modifier, and a fluorescent coloring agent, specifically 4′,6-Diamidino-2-phenylindole dihydrochloride (DAPI), which imparts fluorescent characteristics to the implant guide, enhancing visibility and mechanical strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional implant guides are manufactured, then the market growth is rapid, but the physical properties are non-uniform and cytotoxicity occurs
Solution Approach 1:
The patent modifies the resin composition parameters by incorporating specific fluorescent dyes ( fluorescein isothiocyanate, rhodamine 6G, or cyanine 3) and controlling the ratio of monomers (BIS-GMA, BIS-EMA, UDMA) and additives to achieve uniform physical properties and eliminate cytotoxicity while maintaining rapid manufacturing capability
Solution Approach 2:
The patent creates a composite resin material combining multiple monomers (BIS-GMA, BIS-EMA, UDMA) with fluorescent dyes and functional additives to achieve both uniform physical properties and biological safety, resolving the contradiction between rapid production and material reliability
2Ease of manufacture
If conventional implant guides are used, then the procedure can be performed, but side effects such as bleeding, swelling, and infection occur
Solution Approach 1:
The patent converts the potential harm of cytotoxic materials into benefit by using fluorescent dyes that provide real-time visualization guidance while maintaining biocompatibility, eliminating side effects like bleeding and swelling while preserving procedure feasibility
Solution Approach 2:
The patent introduces fluorescent dyes as intermediary substances that enable better visualization and guidance during the procedure while acting as biocompatible mediators that prevent direct tissue damage, thereby eliminating harmful side effects
3Ease of operation
If conventional implant guides are used, then the placement can be guided, but dislodgement and fracture occur after the procedure
Solution Approach 1:
The patent optimizes the resin composition parameters by adjusting the ratios of BIS-GMA, BIS-EMA, and UDMA monomers, and incorporating reinforcing additives to enhance the mechanical strength and fracture resistance while preserving the placement guidance functionality
Solution Approach 2:
The patent develops a composite material system combining multiple monomers with different mechanical properties and reinforcing additives to achieve both guidance capability and resistance to dislodgement and fracture
4Measurement precision
If fluorescent coloring agents are added to enhance visibility, then the guidance accuracy improves, but the mechanical strength may be compromised
Solution Approach 1:
The patent optimizes the concentration and type of fluorescent coloring agents while adjusting the monomer ratios and additive content to maintain mechanical strength even with enhanced fluorescent visibility for accurate guidance
Solution Approach 2:
The patent creates a composite system where fluorescent dyes are integrated with a multi-monomer resin matrix and reinforcing additives to achieve both high guidance accuracy through fluorescence and sufficient mechanical strength for clinical use
