Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for producing dentures and partial dentures are complex and require significant expertise, as they involve mechanical adjustments of articulators to simulate jaw movements, which can be prone to errors and require manual assembly and parameter transfer.
Innovation Solution
A virtual model of the patient's teeth and jaw is created using electronic recording systems and software, allowing for automatic simulation of jaw movements and insertion of dentures, eliminating the need for mechanical adjustments and ensuring accurate parameter transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mechanical articulator is used to simulate jaw movements, then the functional occlusion can be checked, but the device complexity and difficulty of operation increase significantly
Solution Approach 1:
The patent creates a digital copy (virtual model) of the patient's dentition and jaw movements instead of using a physical articulator. The virtual model replicates all the functional characteristics of the mechanical system but in a simplified digital environment that can be manipulated and analyzed without physical adjustment complexity.
Solution Approach 2:
The patent replaces the mechanical articulator system with a computer-based virtual simulation system. Instead of physically adjusting mechanical components to simulate jaw movements, the system uses software to digitally replicate and analyze eccentric jaw positions and occlusion relationships.
2Manufacturing precision
If manual parameter transfer to articulator is performed, then the patient-specific occlusion can be configured, but the risk of parameter errors and loss of time increases
Solution Approach 1:
The patent replaces manual parameter transfer procedures with automated digital data capture and processing. Electronic recording systems directly capture patient-specific parameters and automatically transfer them to the virtual model, eliminating the manual transcription process that is prone to errors and time-consuming.
Solution Approach 2:
The system incorporates automated feedback loops where the virtual model continuously validates and adjusts parameters based on digital recordings of patient anatomy and jaw movements. This automated feedback mechanism ensures parameter accuracy without requiring manual verification and adjustment.
3Adaptability or versatility
If mechanical articulator adjustments are made, then the condyle path and Bennett angle can be simulated, but the ease of manufacture and operation deteriorates
Solution Approach 1:
The patent creates a virtual copy of the jaw movement mechanics that can be manipulated digitally. The virtual model preserves all the adaptability features for simulating condyle paths and Bennett angles but allows these complex movements to be configured and analyzed through software interfaces rather than manual mechanical adjustments.
Solution Approach 2:
The system uses dynamic digital simulation to model jaw movements, allowing real-time adjustment and analysis of eccentric positions. The virtual model can dynamically adapt to different jaw movement scenarios without requiring physical reconfiguration of mechanical components.

AI summary
The invention relates to a method for producing a dental prosthesis or partial dental prosthesis, wherein a model is created of the set of teeth, or part of the set of teeth, of the patient to be treated, the dental prosthesis or partial dental prosthesis is produced on the basis of the model and is inserted into the model, and the quality of the prosthesis is checked by moving the upper jaw and the lower jaw of the model of the set of teeth relative to one another. In order to make it easier for the method to be carried out, the model of the set of teeth is created by incorporation of the mandibular joint as a virtual model, the prosthesis is produced virtually and inserted into the model, and the quality of the prosthesis is checked by virtual movement of the set of teeth via the virtual mandibular joint.
