Problem
Dental surgery procedures require improved accuracy and reduced tissue damage, often involving multiple tools and complex steps, with a need for simpler and more cost-effective systems that minimize healing time and pain.
Innovation Solution
A dental drill system featuring a drill with a snap-lock drill stop sleeve for precise depth control, a guiding sleeve for directional alignment, and a punching sleeve for controlled tissue punching, allowing for versatile drill usage and reduced equipment complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate tools are used for drilling, guiding, and tissue punching, then functional versatility is achieved, but device complexity increases
Solution Approach 1:
The patent combines the drill, guiding sleeve, and punching sleeve into a single integrated drilling system. The guiding sleeve and punching sleeve are integrated components that work together with the drill bit, eliminating the need for multiple separate tools while maintaining all necessary functions for dental implant procedures.
Solution Approach 2:
The integrated drilling system is designed to perform multiple functions: the guiding sleeve provides directional guidance, the punching sleeve creates the initial tissue opening, and the drill bit drills the bone. This multi-functional design allows a single system to replace multiple specialized tools, reducing complexity while maintaining versatility.
2Manufacturing precision
If a fixed drill depth is used, then drilling accuracy is improved, but adaptability to different implant depths is reduced
Solution Approach 1:
The drill stop sleeve is designed with a movable, adjustable stop mechanism that can be positioned at different depths along the drill shaft. This dynamic adjustment capability allows the system to maintain precise depth control (accuracy) while adapting to various implant depths (versatility), resolving the contradiction between fixed precision and flexible adaptability.
Solution Approach 2:
The depth control mechanism is segmented into adjustable sections, allowing the stop depth to be independently modified. This segmentation enables the system to maintain accurate depth control for each specific procedure while providing overall adaptability to different implant requirements.
3Manufacturing precision
If a secure drill stop mechanism is used, then drilling precision is improved, but ease of operation is reduced
Solution Approach 1:
The drill stop mechanism uses a dynamic snap-fit design that allows for quick engagement and disengagement. The adjustable stop can be easily positioned and locked into place, providing secure depth control while maintaining ease of operation through simple, tool-free adjustment mechanisms.
Solution Approach 2:
The drill stop mechanism is pre-configured with adjustment capabilities that allow the desired depth to be set before the drilling operation begins. This preliminary setup ensures precise depth control during drilling while simplifying the actual drilling operation, as the depth control is already established.

AI summary
A dental drill system is provided, comprising a drill having a drilling part with a first end configured for drilling a hole in a jaw bone and a shank part with a second end configured for connection to a drill-rotating device and a guiding sleeve for guiding the drill. The guiding sleeve has a first side facing the drill-rotating device and a second side intended to face the jaw bone during a drilling operation. A guiding through-hole extends from the first side to the second side. A rim also extends at least partly around the circumference of the drill, and the system comprises a drill stop sleeve provided with a recess extending circumferentially around an inner side of the drill stop sleeve, allowing the drill stop sleeve to be snap-locked onto the drill. The guiding sleeve also comprises a flange that defines an end position for the drill stop sleeve.
