Dental Prosthesis Framework With Porous Mesh for Tissue Ingrowth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dental prosthesis installation methods are time-consuming, costly, uncomfortable for patients, and prone to misalignment due to non-uniform bone targets, and traditional crowns lack hygiene and aesthetic appeal, with unguided drilling causing additional issues.
Innovation Solution
A dental framework with a bar portion and porous mesh that allows soft tissue ingrowth, anchored to the bone via implants, enabling direct attachment of crowns and maintaining tissue health, with a method involving gum flap opening and implant installation followed by crown connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional two-step installation method is used, then crown can be attached to bone screw, but installation time and cost increase substantially
Solution Approach 1:
The framework integrates multiple functions into a single component: it serves as both the anchor structure that attaches to bone via implants and the mounting structure for crowns. The framework includes integrated elements such as the bar portion with threaded openings for crowns and the porous portion for tissue integration, eliminating the need for separate attachment procedures and reducing installation time while maintaining reliability
2Shape
If traditional crown design is used, then tooth replication is achieved, but hygiene and aesthetics are compromised
Solution Approach 1:
The framework separates the crown from the underlying structure by introducing a porous mesh layer between them. This segmentation allows the crown to maintain its tooth-replicating shape while the porous layer provides a pathway for tissue integration and hygiene maintenance, enabling cleaning access and preventing the harmful effects of trapped debris under the crown
3Ease of manufacture
If unguided drilling is used, then implant installation is simpler, but misalignment and hole widening occur
Solution Approach 1:
The framework includes pre-formed implant openings with guides that are created during framework manufacturing. These pre-prepared openings provide built-in guidance for drill placement and orientation, ensuring accurate alignment and preventing hole widening during implant installation, thereby maintaining both simplicity and precision
4Object-affected harmful factors
If porous portion is added to framework, then tissue health is maintained, but framework complexity increases
Solution Approach 1:
The framework applies different properties to different regions: the bar portion maintains a solid, dense structure for mechanical strength and crown attachment, while the porous portion is localized to specific areas where tissue integration is needed. This local differentiation maintains tissue health through the porous regions without unnecessarily complicating the entire framework structure
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
Facilitates efficient, comfortable, and aesthetically pleasing dental prosthesis installation with improved hygiene and natural appearance, allowing for easy cleaning and reduced healing time.
Implementation Method 1
The porous portion has pores or openings, such as a mesh, which allows the growth of soft tissue through the porous portion

AI summary
A dental framework is provided. The framework may be attached to a patient between bone and gums in a patient's mouth, with the framework being suited to receive one or more crowns, i.e. prosthetic teeth. The framework has a bar which receives the crown(s) and a mesh portion which allows the in-growth of soft tissue (gums).
