Cannulated Dental Implant Placement With Guided Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dental implant installation methods lack the technology to accurately position and orient implants in the correct direction, leading to frequent misplacement and misalignment, which can require sacrificing healthy teeth and cause mechanical obstacles.
Innovation Solution
The Precision Dental Implant System (PDIS) uses cannulated implants and a Position Implant Explorer (PIE) to ensure precise alignment and orientation, allowing for repositioning if necessary, combined with cannulated drills and set screws to secure the implant in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional manual drill placement is used, then the procedure is simple and quick, but the positioning accuracy and orientation precision are poor
Solution Approach 1:
The patent introduces a guide template as an intermediary device between the surgeon's manual drilling and the bone. This template pre-defines the exact position, orientation, and depth of the implant site, allowing accurate placement without complex real-time measurements during surgery. The template acts as a mediator that translates the desired implant position into a physical guide for drill placement.
Solution Approach 2:
The guide template is designed and positioned before the actual drilling begins. All positioning calculations, orientation adjustments, and depth markings are performed in advance on the template itself. This preliminary preparation ensures that when drilling starts, the path is already predetermined and accurate, eliminating the need for complex real-time adjustments.
2Manufacturing precision
If manual drilling without guidance is used, then the procedure is fast, but the implant orientation and alignment are inaccurate
Solution Approach 1:
The guide template is prepared in advance with all orientation markings, drill hole positions, and depth indicators pre-established. This preliminary configuration of the template eliminates the need for time-consuming measurements and adjustments during the actual implantation procedure, achieving both high precision and efficiency.
Solution Approach 2:
The guide template creates a physical copy or replica of the ideal implant position and orientation based on pre-surgical planning. By transferring the planned implant geometry onto the template, which then guides the drilling, the system achieves precise reproduction of the desired implant orientation without requiring complex real-time measurement tools during surgery.
3Measurement precision
If visual/manual placement is used, then the equipment is simple, but the positioning accuracy cannot achieve 100% correctness
Solution Approach 1:
The guide template serves as a tangible intermediary that bridges the gap between digital treatment planning and physical implant placement. It translates complex 3D positioning requirements into simple physical guides that can be easily manufactured and used in the operating room, achieving high accuracy without requiring complex electronic measurement systems.
Solution Approach 2:
The patent replaces complex electronic measurement and navigation systems with a purely mechanical guide template system. The template uses physical geometry, pre-drilled guide holes, and mechanical constraints to ensure accurate implant placement, eliminating the need for sophisticated electronic equipment while achieving comparable or superior precision.

AI summary
The present dental implant, whether tapered or cylindrical, is cannulated, to allow placement over a slender post pre-embedded into the host bone. The post is a rigid, not a flexible, construct that can be placed accurately, as to position and angle, in the jawbone. With the post in the correct position, the implant is then installed directly over the temporarily anchored post, and after tightening of the implant by rotation the post is removed.
