Dental Prosthesis Emergence Surface Adjustment via Soft Tissue Scan
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dental prosthesis design systems require time-consuming and difficult manual manipulation of 3D abutment surfaces to match them with soft tissue, lacking efficient methods for adjusting the emergence surface of dental prostheses based on soft tissue scans.
Innovation Solution
The system allows for the receipt of a 3D scan of soft tissue, defining an emergence portion and offset information to automatically adjust the emergence surface of the dental prosthesis, enabling quick and precise alignment or offsetting to match or compress with the soft tissue, producing manufacturing data for the prosthesis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual manipulation of 3D abutment surfaces is used to match with soft tissue, then the prosthesis can be customized to fit patient-specific soft tissue, but the process becomes time-consuming and difficult
Solution Approach 1:
The patent replaces manual mechanical manipulation of 3D model surfaces with an automated algorithmic approach. The system automatically adjusts the emergence surface of the prosthesis by processing 3D soft tissue scan data, eliminating the need for operators to manually manipulate multiple individual points on the 3D surface while achieving precise fitting.
Solution Approach 2:
The system changes the approach from manual point-by-point adjustment to automated parameter-based modification. By receiving offset information and automatically determining the emergence surface shape based on soft tissue scan parameters, the system efficiently adjusts the prosthesis geometry without time-consuming manual intervention.
2Manufacturing precision
If multiple individual points on the 3D surface are manipulated to form the desired shape, then the prosthesis can be precisely shaped, but the operation becomes complex and difficult
Solution Approach 1:
The patent extracts the complex manipulation task from manual operation and isolates it as an automated processing step. The system automatically determines the emergence surface shape by processing 3D soft tissue scan data and applying offset information, removing the complexity of manipulating multiple individual points from the operator's workload.
Solution Approach 2:
The system performs self-adjustment of the prosthesis emergence surface without requiring manual intervention. The automated algorithm processes the 3D soft tissue scan and automatically generates the appropriate prosthesis shape, making the system self-sufficient and eliminating the need for complex manual operations.

AI summary
Herein are provided methods, systems, computer-readable media, techniques and processes for adjusting dental prostheses based on soft tissue. These include allowing an operator to define the surface of a dental prosthesis, such as an abutment, that is proximal to the patient's gum relative to a 3D scan of the patient's gums. The operator can define the offset of that surface as well as the limits of that surface.
