Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current periapical radiography techniques in dental implantology face challenges in maintaining parallelism and perpendicular alignment between the radiographic plate and implant-related instruments, leading to geometric distortion and inaccurate measurements, which compromises implant placement precision.
Innovation Solution
A device that ensures a rigid parallel relationship between the radiographic plate and implant-related instruments, maintaining a fixed perpendicular alignment with the X-ray beam, providing a secure intraoperative reference for verifying implant position and depth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the Rinn device is used for periapical radiography in implantology, then the X-ray beam can be kept perpendicular to the radiographic plate, but the device cannot maintain parallelism between the radiographic plate and implant-related instruments, leading to geometric distortion
Solution Approach 1:
The patent combines the Rinn device with a custom-made holder that integrates the plate holder, bite block, and alignment guide into a single unified structure. This merged system allows the radiographic plate to be simultaneously aligned with both the X-ray beam (perpendicular) and the implant-related instruments (parallel), eliminating geometric distortion while maintaining measurement precision.
Solution Approach 2:
The patent introduces an intermediary alignment guide structure that acts as a mediator between the Rinn device and the implant-related instruments. This intermediary component transfers the perpendicular alignment of the X-ray beam to the parallel alignment with the instruments, solving the contradiction between these two alignment requirements.
2Reliability
If preoperative radiographic studies are performed to assess bone volume and locate anatomical structures, then implant placement planning can be performed, but discrepancies arise when transferring pre-surgical radiographic information to intraoperative conditions
Solution Approach 1:
The patent performs preliminary alignment of the radiographic plate and instruments before taking the intraoperative radiograph. By establishing the correct geometric relationship between the plate, X-ray beam, and implant-related instruments in advance, the system ensures that the intraoperative radiograph accurately reflects the actual implant position and depth, eliminating discrepancies with preoperative planning.
Solution Approach 2:
The patent enables real-time feedback by taking intraoperative radiographs during the implant placement procedure. The radiographic information obtained immediately after drilling allows the surgeon to verify drilling accuracy and make real-time corrections before implant placement, creating a feedback loop that improves measurement precision and reliability.
3Manufacturing precision
If the parallelism or long-cone radiographic technique is used, then geometric distortion is minimized, but the radiation source must be at a minimum distance of 40 cm, reducing projection distortion
Solution Approach 1:
The patent merges the Rinn device with a custom holder that integrates the plate holder, bite block, and alignment guide into a single unified structure. This integrated design automatically maintains the required 40 cm distance between the radiation source and the radiographic plate while ensuring proper parallelism and perpendicular alignment, simplifying the positioning requirements without compromising image distortion minimization.
