Dental Drill Sets With Uniform Guide Sections for Implant Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dental drilling processes require frequent changes of reduction sleeves or drill handles, increasing workload and error risk, especially for wide drills, and lack precise guidance during implant preparation.
Innovation Solution
A set of dental drills with identical guide section diameters and heights, featuring a drill stop and optional groove or bead for maximum depth control, allowing lateral insertion into drill guides, ensuring consistent guidance and preventing over-drilling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If different reduction sleeves or drill handles are used for different drill diameters, then precise guidance is achieved, but device complexity and workload increase
Solution Approach 1:
The guide section of the dental drill is designed to have a uniform diameter across all drill sizes in the set, allowing a single reduction sleeve to guide multiple different drill diameters. This universal guide section diameter enables one reduction sleeve to perform multiple functions that previously required multiple different sleeves.
Solution Approach 2:
The guide section acts as an intermediary element between the cutting part of varying diameters and the reduction sleeve of fixed diameter. By introducing this intermediate guide section with standardized diameter, the system mediates between different drill sizes and a single reduction sleeve interface.
2Adaptability or versatility
If reduction sleeves are frequently changed during drilling, then adaptability to different drill sizes is achieved, but productivity decreases
Solution Approach 1:
A single reduction sleeve can accommodate multiple drill sizes through the standardized guide section, eliminating the need to change sleeves during the drilling sequence. This maintains adaptability to different drill diameters while significantly improving productivity by reducing tool changes.
Solution Approach 2:
The guide section is pre-designed with a standardized diameter on all drills before use, allowing a single reduction sleeve to be prepared in advance for use with multiple drill sizes throughout the entire implant preparation sequence.
3Manufacturing precision
If wide drills are used for implant preparation, then complete bone preparation is achieved, but guidance precision is lost
Solution Approach 1:
The drill is segmented into distinct functional sections: a cutting part with varying diameter for bone removal and a guide section with standardized diameter for precise guidance. This segmentation allows the wide cutting part to perform complete bone preparation while the narrower guide section maintains guidance precision through the reduction sleeve.
Solution Approach 2:
Different sections of the drill have different diameters optimized for their specific functions. The cutting part has a larger diameter for effective bone removal, while the guide section has a standardized smaller diameter for precise guidance, with each section having local quality optimized for its purpose.

AI summary
The set has two dental drills (10, 10') e.g. rose-head bur, pilot bit, profile drill, spiral drill and screw tap, comprising two shaft parts (30, 30') with two accommodating end regions (32, 32') that are provided for accommodating in a drill holder device, respectively. The shaft parts respectively have circular cylinder-shaped guiding regions (40, 40') for guiding the drills, where the guiding regions have same diameter of 2.8 mm and same height. The guiding regions have length of approximately 4 to 6 mm, and the shaft parts have a groove or bead for fastening a drill stop.
