Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for inserting multiple dental replacement products into a patient's mouth often result in complications due to manual adjustments and trial-and-error approaches, leading to suboptimal tooth shapes and potential discomfort for the patient.
Innovation Solution
A method that digitally plans the restorative dental treatment by calculating an optimum sequence and insertion paths for dental restorations, avoiding conflicts and ensuring smooth insertion, using CAD/CAM technology to provide a guide for the treating dentist.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual adjustments and trial-and-error approaches are used for inserting multiple dental replacement products, then the dental technician can make appropriate adjustments to the model ahead of time, but problems occur during insertion requiring reworking, grinding, or even removal of existing teeth
Solution Approach 1:
The system performs preliminary simulation of the insertion process digitally before actual clinical application. The insertion sequence and paths are calculated and optimized in advance using computer algorithms, allowing potential conflicts to be identified and resolved before the actual restoration insertion, thereby eliminating the need for manual trial-and-error adjustments during the procedure
Solution Approach 2:
The invention creates a digital copy (virtual model) of the patient's dentition and restorations. This digital replica allows for repeated simulation and optimization of insertion sequences without affecting the actual restorations or patient anatomy. The optimized insertion plan derived from the digital copy is then transferred to guide the actual clinical procedure
2Productivity
If digital methods are used for designing restorations with CAD/CAM technology, then production efficiency is improved, but the insertion process becomes more complex requiring calculation of optimum sequences and paths
Solution Approach 1:
The system performs self-planning of the insertion sequence and paths through automated computer algorithms. The software independently calculates the optimal insertion order and trajectories by analyzing the geometric relationships between restorations and adjacent structures, eliminating the need for manual planning and reducing the complexity burden on the operator
Solution Approach 2:
The invention replaces manual mechanical planning methods with computer-based algorithmic calculation. Instead of relying on the dental technician's manual manipulation of physical models to figure out insertion sequences, the system uses computational algorithms to automatically determine the optimal insertion plan, thereby managing complexity through automation rather than human cognition
3Device complexity
If no insertion sequence optimization is performed, then the treatment process is simpler, but conflicts during insertion require time-consuming reworking and remaking of restorations
Solution Approach 1:
The system performs preliminary optimization of the insertion sequence digitally before the actual treatment. By calculating the optimal insertion order and paths in advance using computer algorithms, potential conflicts are identified and resolved during the planning phase, preventing time-consuming rework during the actual restoration insertion procedure
Solution Approach 2:
The invention uses a digital copy of the dentition and restorations to simulate and optimize the insertion process. This virtual simulation allows for efficient testing of different insertion sequences without affecting the actual restorations, enabling rapid optimization while keeping the actual treatment simple and time-efficient

AI summary
In a method of planning a restorative dental treatment for a patient, at least two dental restorations are digitally constructed (20). In the process, an optimum specification (40) for the insertion of the restorations into the mouth of the patient is calculated (30), wherein the optimum specification for the insertion of the restorations comprises an optimum sequence of the restorations to be inserted; if applicable, including optimum insertion paths for the restorations to be inserted.
