Dental Surgical Guide Components for Secure, Accurate Implant Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dental implant systems lack components that ensure precise, non-rotational orientation and secure fixation of surgical guides during implant placement, leading to potential misalignment and damage to nearby teeth or bone structures.
Innovation Solution
Incorporation of irrigation channels, grooved guide bodies, threaded fixation pins, and interchangeable drill components to enhance stability and accuracy of surgical guides, including custom drills with prolongation attachments and hybrid bone taps for varied surgical conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional surgical guides are used without specialized fixation components, then the surgical guide can be easily placed, but it lacks secure fixation and precise non-rotational orientation
Solution Approach 1:
The surgical guide system is divided into separate functional components: fixation pins with threaded portions for secure attachment, master tubes with irrigation channels for fluid delivery, and guide bodies with grooves for alignment. This segmentation allows each component to perform its specific function optimally while maintaining overall system reliability.
Solution Approach 2:
Threaded fixation pins act as intermediaries between the surgical guide and the bone structure, providing secure mechanical attachment. The pins with threaded portions engage with the bone to prevent movement and rotation of the surgical guide during the procedure.
2Productivity
If surgical guides are used without irrigation channels, then the structure remains simple, but debris cannot be cleared during drilling
Solution Approach 1:
The master tube is designed to combine multiple functions: it serves as a guide for the drill bit, provides a housing for the irrigation channel, and acts as a structural support element. The irrigation channel is integrated within the master tube structure, allowing fluid delivery without adding external complexity.
Solution Approach 2:
Irrigation channels are incorporated into the master tube to deliver fluid flow for cooling the drill site and removing debris. The hydraulic system allows continuous fluid delivery through the master tube during drilling operations.
3Ease of operation
If guide bodies without grooves are used, then manufacturing is simpler, but irrigation cannot be effectively provided during drilling
Solution Approach 1:
The guide body is segmented with grooves that create separate pathways for fluid flow. These grooves divide the internal space to allow effective irrigation while maintaining a relatively simple overall structure that can be manufactured using standard techniques.
4Manufacturing precision
If surgical guides without non-rotational features are used, then placement is easier, but the implant cannot be oriented correctly
Solution Approach 1:
Non-rotational features such as asymmetric grooves, keyways, or shaped openings are incorporated into the surgical guide and master tube. These asymmetric elements prevent rotation of the implant during placement, ensuring correct orientation while adding minimal complexity to the overall structure.
