Dental Drill Guide with Slit Sleeve for Precision Implant Drilling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current drill guides for dental implants face challenges in handling small reduction sleeves, particularly in sterically hindered sites and with dental drills having wide drilling portions, leading to imprecise drilling and handling difficulties.
Innovation Solution
A drill guide with a hollow cylindrical guide sleeve featuring a longitudinal slit allows for lateral insertion of dental drills, accommodating drills with wide drilling portions and enabling precise guidance in limited spaces, and can be adjusted for different diameters and heights to fit various drilling needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If reduction sleeves with small diameters are used to guide dental drills, then drilling precision is improved, but handling difficulty increases and aspiration risk increases
Solution Approach 1:
The patent introduces a holder as an intermediary device that securely receives and stabilizes the small reduction sleeve during the drilling process. This holder acts as a mediator between the surgeon's hand and the tiny reduction sleeve, providing a larger grip surface and preventing accidental displacement or aspiration of the small component while maintaining the precision benefits of the small-diameter reduction sleeve.
2Manufacturing precision
If reduction sleeves with small diameters are used to guide dental drills, then drilling precision is improved, but aspiration risk increases
Solution Approach 1:
The holder serves as a protective intermediary that prevents the small reduction sleeve from becoming a foreign body aspiration risk. By providing a secure receiving structure that maintains control over the small component throughout the drilling process, the holder eliminates the risk of the reduction sleeve being inadvertently inhaled or swallowed, while preserving the precision advantages of using small-diameter reduction sleeves.
3Manufacturing precision
If reduction sleeves with certain height are used to achieve optimal guidance, then drilling precision is improved, but space requirement increases
Solution Approach 1:
The patent segments the guidance function into two separate components: the reduction sleeve, which provides the critical guidance and precision functions, and the holder, which provides the structural support and space-efficient mounting. This segmentation allows the reduction sleeve to be optimized for precision with minimal height, while the holder manages the overall spatial requirements through its compact design and integration with the template structure.
4Manufacturing precision
If standard drill sleeves are used in templates, then guidance precision is improved, but adaptability to different drill diameters decreases
Solution Approach 1:
The holder is designed as a universal receiving structure that can accommodate reduction sleeves of various diameters through a single standardized interface with the template. This universal design allows the same holder to work with multiple drill sizes by simply changing the reduction sleeve, providing adaptability to different drill diameters while maintaining the guidance precision provided by the template-integrated holder structure.

AI summary
The present invention relates to a drill guide (1) for use in the dental field, comprising a grip (10), a bearing surface intended to bear at least partially on a template (50) or a drill sleeve (55), and at least one guide sleeve (20). The grip (10) has a top face and an underside. The at least one guide sleeve (20) is essentially hollow cylindrical, has an upper and a lower end, and protrudes from the underside of the grip (10). The drill guide (1) is characterized by the fact that the at least one guide sleeve (20) comprises a longitudinal slit (30).
