Dental Implant Guide Manufacturing Using CT Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conventional method of manufacturing dental implant placement guides is complex, time-consuming, and prone to inaccuracies due to the need for multiple scanning operations and integration of images, leading to irregularities and errors in precision.
Innovation Solution
A method utilizing only a CT image to design and manufacture a dental implant placement guide, which involves applying a preliminary guide to the patient's implant region, partially curing an impression resin, removing the guide, reapplying it, and using the CT image to design the guide hole, thereby simplifying operations and ensuring high accuracy and precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple scanning operations and image integration are performed to manufacture a surgical guide, then comprehensive oral cavity information is obtained, but operation complexity and operating time increase significantly
Solution Approach 1:
The invention extracts and eliminates the unnecessary oral scan operation from the conventional multi-step process. By using only the CT scan image which already contains sufficient information for implant guide manufacturing, the patent removes the complexity of multiple scanning operations and image integration while maintaining the reliability of the final guide.
Solution Approach 2:
The patent uses the CT scan image as a sufficient copy of oral cavity information, replacing the need for additional oral scan copies. The CT image alone provides all necessary anatomical data for creating the implant guide, eliminating the need to integrate multiple image sources.
2Reliability
If multiple scanning operations and image integration are performed to manufacture a surgical guide, then comprehensive oral cavity information is obtained, but operating time becomes excessively long
Solution Approach 1:
The invention extracts and eliminates the time-consuming oral scan operation and image integration steps from the conventional process. By relying solely on the CT scan image, the patent significantly reduces operating time while maintaining comprehensive oral cavity information for accurate guide manufacturing.
3Reliability
If multiple scanning operations and image integration are performed to manufacture a surgical guide, then comprehensive oral cavity information is obtained, but accuracy and precision become irregular due to error accumulation
Solution Approach 1:
The invention extracts and eliminates the error-prone image integration step from the conventional process. By using only the CT scan image without integrating oral scan images, the patent removes the source of error accumulation and irregularity, ensuring constant and high manufacturing precision of the implant guide.
4Productivity
If a simplified process using only CT image is used to manufacture a dental implant placement guide, then operation complexity and operating time are significantly reduced, but comprehensive oral cavity information may be insufficient
Solution Approach 1:
The patent changes the parameter of information source from multiple image types (CT scan + oral scan) to a single CT scan image. The CT scan technology provides sufficient density resolution and anatomical detail for implant guide manufacturing, making additional oral scans unnecessary while maintaining comprehensive oral cavity information.
