Interlocking Dental Surgical Template and False Teeth Set
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for accurately placing dental implants in the jawbone are imprecise, often resulting in imperfect bore drilling, tissue damage, uneven force distribution, and potential implant failure due to the lack of precise guidance during the drilling process.
Innovation Solution
A combination of a surgical template and a false teeth set that interlock to form a denture prosthesis, with the surgical template having drill holes and pin holes for secure placement, manufactured using CT scans and CNC milling, allowing for precise osteotomy drilling and bone reduction, and convertible to a temporary or final prosthesis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If freehand drilling method is used, then surgical operation is simple and quick, but implant placement precision deteriorates
Solution Approach 1:
The surgical template is prepared in advance with pre-determined drill hole positions, angles, and depths based on CT scan data and treatment planning. This preliminary preparation allows the surgeon to simply attach the template to the patient's jaw and drill through the pre-marked holes, eliminating the need for complex intraoperative calculations while ensuring precise implant placement.
Solution Approach 2:
The surgical template serves as an intermediary device between the treatment plan and the actual drilling operation. It translates the digital treatment plan into physical guidance on the patient's jaw, providing a tangible reference for drill hole positions and angles without requiring the surgeon to perform complex measurements during surgery.
2Manufacturing precision
If surgical template is used, then implant placement precision is improved, but device complexity increases
Solution Approach 1:
The surgical template is divided into multiple segments or sections, each corresponding to a specific implant site. This segmentation allows the template to be customized for each patient's unique jaw structure while maintaining a relatively simple overall design. Each segment can be independently manufactured and then assembled, reducing the complexity of creating a single monolithic template.
Solution Approach 2:
The surgical template incorporates different features at different locations to match the specific requirements of each implant site. For example, some areas may have depth stops while others have angle guides, and the material properties or surface characteristics may vary locally to optimize attachment and drilling guidance. This localized customization provides precise guidance without requiring the entire template to be overly complex.
3Manufacturing precision
If multiple surgical steps are performed separately, then each step can be optimized, but total surgery time increases
Solution Approach 1:
The surgical template combines multiple functions into a single device: it provides guidance for drill hole positioning, angle control, depth limitation, and even serves as a reference for implant placement. By merging these previously separate surgical steps and tools into one integrated template, the overall surgery time is reduced while maintaining or improving the precision of each individual step.
