Dental Implant Drilling Gauge with Correctable Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dental implant placement methods are costly and uncertain, especially when dealing with narrow bone crests or anatomical complexities, as they require expensive equipment and lack effective verification and correction of drilling guides.
Innovation Solution
A method and stent device for manufacturing a drilling template using a plaster model of the jaw, where a drill guide is introduced and corrected by replacing a stake with a part having a different axis, and then immobilized in a thermoformed resin gutter, allowing for precise positioning and verification using tomography or other imaging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If expensive equipment and software are used for digital planning and drilling guide production, then drilling precision is improved, but device cost and complexity increase
Solution Approach 1:
The patent creates a physical copy (drilling guide) based on digital planning data, allowing the information to be transferred to a tangible form that can be directly used during surgery without requiring expensive real-time digital guidance equipment
Solution Approach 2:
The drilling guide is designed as a disposable, inexpensive physical template that can be manufactured cheaply and discarded after use, eliminating the need for expensive reusable equipment and reducing overall system cost
2Manufacturing precision
If digital drilling guides are used for implant placement, then drilling direction accuracy is improved, but the ability to verify and correct position is lost
Solution Approach 1:
The patent incorporates verification holes and reference markers in the drilling guide that allow direct visual and physical verification of position during surgery, providing immediate feedback on whether the drilling direction and location match the planned position
Solution Approach 2:
The physical drilling guide acts as an intermediary between the digital planning phase and the surgical execution phase, allowing manual verification and correction of position through direct observation and adjustment before drilling begins
3Reliability
If minimal incisions are made to preserve bone and reduce post-operative consequences, then bone healing is improved, but drilling accuracy becomes more difficult to achieve
Solution Approach 1:
The drilling guide is prepared in advance based on digital planning and verified before surgery, allowing the surgeon to proceed with minimal incisions while maintaining drilling accuracy through pre-positioned reference markers and verification holes

AI summary
The invention relates to a drilling gauge for placing a dental implant that comprises carrying out the following operations: making a gypsum model (1) of the jaw to be treated; in the gypsum model (1) drilling a bore (12) along an estimated axis; inserting into said bore (12) a portion of a stent and adapting on the other protruding portion a bore guide (3); checking the position of the bore guide (3), correcting the position of the bore guide (3) by replacing the stent (2) with another one (4) having a protruding portion with an axis different from that of the portion inserted into the bore (12) and selected so that the guide (3) is correctly positioned; making a splint of cast or heat-shaped resin on the gypsum model (1) while trapping and immobilising the guide (3) in order to form the drilling gauge.
