Dental Implant Surgical Guide Virtual Fit Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing CAD-CAM methodologies for developing surgical guides for dental implant placement often require revisions due to mismatched implant or instrumentation sizes with the patient's mouth anatomy, leading to inefficiencies and additional patient visits.
Innovation Solution
A method involving scanning the patient's mouth in both closed and opened positions to create a virtual model, allowing for the development of a surgical plan and guide that accounts for the spatial constraints and dimensions of opposing dental structures, ensuring proper fit of instrumentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional CAD-CAM methodologies are used to develop surgical guides, then the surgical guide can be manufactured with precise dimensions, but the instrumentation may not fit properly within the patient's mouth due to mismatched sizes with opposing dental structures
Solution Approach 1:
The patent applies preliminary action by performing virtual checks of the surgical guide and instrumentation against the patient's oral anatomy before manufacturing. The system virtually places the surgical guide and instrumentation in the patient's mouth model to verify fit and compatibility, allowing for preoperative identification and correction of potential size mismatches between instrumentation and opposing dental structures.
Solution Approach 2:
The patent uses a virtual copy or digital model of the patient's mouth and dental structures to simulate and verify the fit of surgical guides and instrumentation. This virtual replica allows the system to check dimensional compatibility without physical prototyping, enabling precise verification of whether instrumentation will properly fit within the patient's actual mouth anatomy.
2Productivity
If surgical guides are developed without checking instrumentation fit, then the manufacturing process is faster, but revisions are required due to mismatched dimensions leading to additional patient visits
Solution Approach 1:
The system performs preliminary virtual verification of instrumentation fit within the patient's mouth model before finalizing the surgical guide design. This preoperative check identifies potential size mismatches and compatibility issues early in the design process, allowing for corrections to be made during manufacturing rather than requiring post-delivery revisions that would necessitate additional patient visits.
3Device complexity
If the surgical guide is designed without considering opposing dental structures, then the design process is simpler, but the instrumentation cannot properly fit within the patient's mouth
Solution Approach 1:
The patent creates a virtual copy or digital representation of the patient's complete oral anatomy including opposing dental structures. This virtual model allows the system to automatically check and verify that the surgical guide and instrumentation will properly fit within the patient's mouth, providing reliable fit accuracy without significantly increasing the complexity of the design process itself.

AI summary
The invention relates to manufacturing a surgical guide to be placed in a patient's mouth. The patient's mouth is scanned to obtain surgical-region scan data at a region where an implant is to be located. The patient's mouth is also scanned in the opened position to acquire dental conditions opposite from the surgical region so as to obtain opposing-condition scan data. A virtual model is developed using the surgical-region scan data and the opposing-condition scan data. Using the virtual model, a surgical plan is developed that includes the location of the implant to be installed in the patient A virtual surgical guide is also developed based on the surgical plan. The dimensions of instrumentation to be used with the surgical guide are checked to ensure they will fit within the mouth by use of the opposing-condition scan data. After checking, final surgical-guide manufacturing information is obtained for manufacturing the surgical guide.
