Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for analyzing space in dental implant restoration rely heavily on clinical experience and lack accurate and efficient measuring means, leading to difficulties in measuring irregular shapes and poor measurement accuracy due to factors like inspection angle and mouth opening degree.
Innovation Solution
A measuring system comprising three assemblies with specific structures and measuring heads, including a T-shaped measuring head for mouth opening and gap measurement, a multi-part measuring assembly for occlusal distance, and a ruler-based assembly for transgingival depth, allowing precise and direct measurement of spatial features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If visual inspection and model analysis are used for space measurement, then the method is simple to perform, but the measurement accuracy is poor and relies on clinical experience
Solution Approach 1:
The patent introduces specialized measuring assemblies (first, second, and third measuring assemblies) as intermediary tools between the clinician and the anatomical structures. These assemblies include connecting rods with specific geometries (L-shaped, T-shaped, etc.) and measuring heads with scales that directly contact and measure the mouth opening degree, gap dimensions, occlusal distance, and transgingival depth, providing objective measurements rather than relying on visual estimation
Solution Approach 2:
The patent replaces the subjective visual inspection method with objective mechanical measurement systems. The measuring assemblies use physical contact and mechanical scales to directly quantify spatial parameters, substituting the clinician's visual judgment with mechanical measurement devices that provide precise numerical data
2Measurement precision
If conventional ruler measurement on irregular denture models is used, then the measuring tool is simple, but the operation process is complicated and measurement accuracy is poor
Solution Approach 1:
The patent divides the measurement task into multiple specialized assemblies, each designed for specific measurement purposes. The first measuring assembly measures mouth opening degree and gap dimensions, the second measures occlusal distance, and the third measures transgingival depth. Each assembly has a connecting rod with a specific measuring head geometry optimized for its measurement function, allowing precise measurement of irregular surfaces without complicated procedures
Solution Approach 2:
The patent transitions from two-dimensional ruler measurements on flat model surfaces to three-dimensional direct contact measurements within the oral cavity. The measuring assemblies are designed to contact irregular surfaces directly in three-dimensional space, with measuring heads that can adapt to curved and uneven anatomical surfaces, providing accurate measurements that account for spatial complexity
3Reliability
If intraoral analysis is performed without considering mouth opening degree and occlusal distance, then the analysis process is simplified, but the reliability of implant restoration is compromised
Solution Approach 1:
The patent performs preliminary measurements of mouth opening degree, gap dimensions, occlusal distance, and transgingival depth before implant restoration planning. The first measuring assembly quantifies mouth opening degree and interproximal gaps, the second measures occlusal distance, and the third measures transgingival depth. These preliminary measurements provide objective data that guide implant selection, positioning, and prosthesis design, ensuring restoration reliability before the actual surgical procedure
Solution Approach 2:
The measuring assemblies are designed with universal applicability for various measurement tasks in dental implant restoration. Each assembly can measure multiple parameters (e.g., the first measuring assembly measures both mouth opening degree and gap dimensions), and the assemblies can be used on both physical models and actual patients, providing consistent measurement capabilities across different clinical scenarios
