Dental Implant Prosthesis Modeling Without a Second Stone Model
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dental implant systems require the creation of a second stone model for developing a final prosthesis, which introduces accuracy limitations and reduces the precision of the final prosthesis.
Innovation Solution
A method is developed to create a rapid prototype of a patient's dentition and dental implant analog using scan data from a stone model with informational markers, which allows for the direct fabrication of a patient-specific prosthesis without the need for a second stone model.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a second stone model is created for developing the final prosthesis, then the prosthesis can be manufactured using traditional methods, but accuracy limitations and precision errors are introduced
Solution Approach 1:
The patent uses a scanning device to create a digital copy of the first stone model containing informational markers. This digital copy is then used to generate the final prosthesis design, eliminating the need to physically create a second stone model. The scanning process captures precise dimensional data and marker positions, transferring accuracy from the first model directly to the prosthesis design without introducing additional modeling errors.
2Ease of manufacture
If a second stone model is created for developing the final prosthesis, then the traditional prosthesis development process can be followed, but the process complexity and patient discomfort increase
Solution Approach 1:
The patent replaces the mechanical process of creating a second stone model with a scanning and digital modeling system. Instead of physically replicating the first stone model through traditional dental modeling techniques, a scanning device optically captures the model's geometry and marker positions, then a computer generates the final prosthesis design digitally. This substitution eliminates the need for manual model-making steps and reduces overall process complexity.
3Ease of manufacture
If a second stone model is created for developing the final prosthesis, then the prosthesis can be developed using conventional methods, but accuracy limitations are introduced
Solution Approach 1:
The patent uses a scanning device to create a digital copy of the first stone model containing informational markers. This digital copy is then used to generate the final prosthesis design, eliminating the need to physically create a second stone model. The scanning process captures precise dimensional data and marker positions, transferring accuracy from the first model directly to the prosthesis design without introducing additional modeling errors.

AI summary
A method for making a rapid prototype of a patient's mouth to be used in the design and fabrication of a dental prosthesis. The method takes an impression of a mouth including a first installation site having a dental implant installed in the first installation site and a gingival healing abutment having at least one informational marker attached to the dental implant. A stone model is prepared based on the impression, including teeth models and model markers indicative of the at least one informational marker. The model is scanned. Scan data is generated from the scanning. The scan data is transferred to a CAD program. A three-dimensional model of the installation site is created in the CAD program. The at least one informational marker is determined to gather information for manufacturing the rapid protocol. Rapid prototype dimensional information is developed. The rapid prototype dimensional information is transferred to a rapid prototyping machine which fabricate a rapid prototype of the patient's dentition as well as a dental implant analog position.
