Dental Prosthesis Positioning Guide for Implant Deviation Tolerance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing one-day implant surgeries face challenges in ensuring proper occlusion of dental prostheses due to potential deviations in implant placement, which can lead to discomfort or pain for the patient, and existing solutions do not adequately address these issues.
Innovation Solution
A method for designing a digital prosthesis and positioning guide that includes creating enlarged abutment holes in the prosthesis design and using a digital guide to ensure proper occlusion, utilizing CAD software and combining surface scans with CBCT images for accurate implant planning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the abutment hole shape is created larger than the digital abutment representation to accommodate implant placement deviations, then the prosthesis can be placed despite minor implant deviations, but the precision of fit between prosthesis and implant may be reduced
Solution Approach 1:
The patent applies preliminary action by pre-enlarging the abutment hole shape in the digital prosthesis design before manufacturing, anticipating potential implant placement deviations. This pre-adjustment allows the prosthesis to accommodate minor deviations without requiring post-placement adjustments, resolving the contradiction between adaptability and precision by built-in tolerance compensation.
2Reliability
If a positioning guide is used to ensure proper occlusion, then the occlusion between prosthesis and opposing jaw is maintained, but the complexity of the procedure increases
Solution Approach 1:
The patent introduces a positioning guide as an intermediary device that mediates between the prosthesis and the patient's jaw. This guide ensures accurate occlusion by providing a reference framework during placement, resolving the contradiction between reliability and complexity by using a specialized tool to simplify the overall alignment process.
3Manufacturing precision
If multiple appointments are scheduled for implant surgery and prosthesis placement, then the precision of each step can be ensured, but the total treatment time increases
Solution Approach 1:
The patent applies preliminary action by creating the digital prosthesis design and positioning guide before the implant surgery. This pre-planning allows for precise fabrication of components that will fit the specific patient's anatomy, enabling high-precision placement in a single appointment rather than requiring multiple visits for adjustments.
Solution Approach 2:
The patent uses digital copying and modeling to create accurate virtual representations of the patient's jaw and teeth. These digital models are used to fabricate custom positioning guides and prostheses that precisely match the patient's anatomy, enabling single-appointment placement with the same precision that would traditionally require multiple appointments.
