Dental Implant Surgical Guide Manufacturing System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical guide manufacturing techniques for dental implant surgery are inefficient due to the separation of surgery planning and guide manufacturing, requiring dentists to be familiar with 3D imaging software and lacking real-time verification of accuracy, which hinders widespread adoption and precision.
Innovation Solution
An integrated surgical guide manufacturing system that uses a cast model navigation device with an articulated arm, decoders, and a computer system to register CT images with the physical cast model, allowing for precise placement and locking of a surgical guide during manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional separate processes for surgery planning and guide manufacturing are used, then dentists can work in familiar environments, but the manufacturing time is long and accuracy verification is delayed
Solution Approach 1:
The patent combines surgery planning and guide manufacturing into an integrated system where the articulated arm navigation device directly interfaces with the surgical guide manufacturing process. The planning software and manufacturing equipment are merged into a unified workflow, allowing real-time verification of implant positions and eliminating the time delay between separate planning and manufacturing stages.
2Manufacturing precision
If 3D imaging software is used for surgery planning, then implant position accuracy is improved, but the system complexity increases and dentists face a learning curve
Solution Approach 1:
The articulated arm navigation device serves as an intermediary between the physical cast model and the 3D imaging software. It provides a familiar tactile interface for dentists while seamlessly integrating with the planning software, reducing the learning curve by maintaining familiar operational workflows while achieving high precision through the navigation system.
3Productivity
If traditional manufacturing methods are used, then equipment requirements are simple, but the separation of planning and manufacturing reduces overall efficiency
Solution Approach 1:
The articulated arm navigation device performs multiple functions: it serves as a measurement tool for the cast model, a positioning system for the surgical guide, and a verification system for implant positions. This multi-functional device integrates planning and manufacturing capabilities, improving overall productivity without requiring entirely separate specialized equipment for each stage.

AI summary
A system and a method for manufacturing a dental implant surgical guide are disclosed. The dentist may obtain a cast model of the patient's jaw and a plurality of CT images of the jawbone and teeth by CT scanning. The system includes a cast model navigation device, a controlling module, and a computer system. The navigation device includes an articulated arm capable of holding a tool and a plurality of braking elements. The articulated arm is operated to measure the positions of markers on the cast model to provide the position registration between the cast model and the plurality of CT images. Once registered, the articulated arm is operated to simulate the target implant position under the guidance of the CT images. The arm can then be locked via the plurality of braking elements controlled by the controlling module for manufacturing of the surgical guide.
