Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dental implant and restoration planning in dentistry relies heavily on human expertise and manual processes, leading to inconsistencies and errors, as software-based systems fail to detect imperfect planning effectively.
Innovation Solution
A computer-based method and system for planning dental restorative procedures that determines spatial positions of dental components within the craniooral space, allowing for automated planning and production of dental restorations without the need for physical models or CT scanning, using anatomically fixed reference points and virtual templates to ensure accurate positioning and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual planning by dentist is used, then flexibility and adaptability are maintained, but human error and inconsistency increase
Solution Approach 1:
The system enables self-service through automated boundary surface determination and spatial position calculation. The computer automatically processes dental unit data, determines boundary surfaces, calculates spatial positions, and generates drill guides without requiring manual measurement or interpretation by the dentist, thereby eliminating human error while maintaining operational simplicity
Solution Approach 2:
The patent replaces manual mechanical planning processes with an automated computer-based system. Instead of manual measurement and visualization, the system uses digital boundary surface determination, automated spatial position calculation, and computer-generated drill guides, substituting mechanical operations with electronic processing to improve accuracy and consistency
2Reliability
If software-based planning is used, then consistency is improved, but detection of planning errors is not achieved
Solution Approach 1:
The system incorporates feedback mechanisms where the determined boundary surfaces and spatial positions are used to generate drill guides that can be verified against the original dental unit data. This feedback loop allows the system to detect and correct planning errors by comparing calculated positions with anatomical constraints and previously determined reference points
Solution Approach 2:
The patent performs preliminary determination of boundary surfaces and spatial positions before final drill guide generation. This preliminary action allows for error detection and correction in the planning stage, ensuring that all calculations are verified against anatomical references and logical constraints before the final product is produced
3Measurement precision
If physical models and CT scanning are used, then accuracy is maintained, but treatment time and inconvenience increase
Solution Approach 1:
The system creates digital copies of the dental units and their boundary surfaces through automated data processing. Instead of requiring physical models or multiple CT scans, the system generates virtual representations that can be measured and processed instantly, maintaining measurement precision while eliminating the time-consuming physical modeling process
Solution Approach 2:
The patent performs all necessary measurements and spatial position determinations in advance through automated processing of digital data. By pre-determining boundary surfaces and calculating spatial positions before treatment, the system eliminates the need for time-consuming physical models and multiple imaging scans, achieving both accuracy and time efficiency

AI summary
Methods are provided for computer-based planning of a dental restorative procedure of a patient having a craniooral space and/or of at least one dental component for the dental restorative procedure. Certain methods include determining a first spatial position of a first boundary surface, in the craniooral space, of a first dental unit of a dental restoration; determining a second spatial position of a second boundary surface, in the craniooral space remote the first boundary surface, of a second dental unit of the dental restoration; and determining a third spatial position of at least a portion of the at least one dental component relative at least one of the first and second spatial positions.
