Digital Implant Planning With Virtual Oral Models
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dental implant procedures lack reliability due to user-dependent implant plan determination, leading to deviations and increased complexity, and there is a risk of loosening or release of the implant subassembly-prosthesis coupling during chewing activities.
Innovation Solution
A digital implant system utilizing a computing device connected to panorama, CT, and 2D/3D imaging devices to automatically obtain oral cavity information, generate implant plans, and enhance the coupling mechanism with rotatable protrusions to prevent loosening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If implant plan is established based on user experience and feeling, then professional judgment is applied, but deviation between users occurs and reliability is impaired
Solution Approach 1:
The patent creates a virtual model (copy) of the patient's oral cavity using imaging data, and performs implant planning in this virtual space. This allows multiple users to work on the same standardized model, eliminating deviations caused by individual interpretations of physical anatomy while preserving professional judgment through software-based decision support.
Solution Approach 2:
The patent replaces the manual, experience-based mechanical process of implant planning with an automated computer-based system that uses imaging data and software algorithms. This substitution eliminates user-dependent variability while maintaining the ability to apply professional judgment through programmable criteria.
2Productivity
If manual implant planning procedure is used, then flexibility in decision-making is maintained, but time required to establish implant plan increases
Solution Approach 1:
The patent performs preliminary actions by acquiring complete imaging data of the oral cavity before implant planning begins, and creates the virtual model in advance. This preliminary preparation eliminates the need for repeated measurements and revisions during the planning process, significantly reducing the time required while maintaining decision-making flexibility.
Solution Approach 2:
By working with a pre-created virtual copy of the oral cavity rather than repeatedly measuring the physical anatomy, the system eliminates time-consuming repeated revisions while preserving the ability to make flexible decisions about implant placement based on the standardized virtual model.
3Reliability
If implant subassembly and prosthesis are coupled traditionally, then assembly is simple, but coupling relationship may be loosened or released during chewing activities
Solution Approach 1:
The patent employs a rotatable protrusion mechanism that allows dynamic adjustment and rotation of the implant subassembly relative to the prosthesis. This dynamic coupling mechanism prevents loosening during chewing by allowing controlled movement while maintaining secure connection, without requiring overly complex locking systems.
Solution Approach 2:
The patent divides the coupling system into separate functional elements: the implant subassembly with protrusion, the prosthesis with receiving structure, and the rotatable connection interface. This segmentation allows each component to be optimized independently while working together to provide stable coupling that resists loosening during functional loading.
