Modular Dental Drill System with Interchangeable Shafts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dental drills are inadequate for the unique challenges of implant dentistry, including limited accessibility within the patient's mouth and anatomical variations, leading to instability and inefficiency due to the need for multiple drill extensions and components.
Innovation Solution
A universal drill system with a small connection interface and interchangeable shafts of varying lengths, allowing quick changes to accommodate anatomical needs, featuring a drill system that can remove dense cortical bone and densify medullary bone for improved implant stability, while being rigid, secure, and easy to use with conventional actuator instruments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional drills with integral shafts are used, then the drill structure is simple, but the drill becomes wobbly and unstable when shaft extenders are required to accommodate different lengths
Solution Approach 1:
The drill system is divided into separate modular components: a handpiece, interchangeable shafts, and drill bits. Each shaft is a standalone component with a standardized connection interface, allowing them to be replaced without affecting the stability of other components. This segmentation eliminates the wobble issue by ensuring each component is precisely manufactured and easily replaceable.
Solution Approach 2:
A universal connection interface is designed that can accommodate multiple shaft lengths and drill bit types. The standardized interface ensures consistent coupling between the handpiece, shaft, and drill bit across all combinations, providing stable operation regardless of which specific shaft or drill bit is used. This universality maintains stability while reducing the need for multiple specialized components.
2Adaptability or versatility
If multiple drill extensions and components are used to accommodate anatomical variations, then the drill can fit different patient needs, but the number of components increases and the system becomes more complex
Solution Approach 1:
The drill system incorporates dynamically adjustable shaft lengths that can be quickly interchanged based on the specific anatomical requirements of each patient. The standardized connection interface allows the operator to select and attach the appropriate shaft length during the procedure, providing adaptability without requiring a large inventory of specialized drill systems. This dynamic interchangeability reduces the total number of components needed while maintaining versatility.
3Ease of operation
If conventional drills are used in the patient's mouth, then the drill can perform bone removal, but the limited mouth opening space makes drilling difficult and reduces accessibility
Solution Approach 1:
The drill system is segmented into a handpiece portion that can be positioned outside the patient's mouth and a shaft-drill bit assembly that extends into the treatment site. This segmentation allows the bulk of the drill mechanism to remain in the accessible oral cavity entrance while only the necessary working portion enters the difficult-to-reach areas, improving accessibility without requiring the entire drill system to be miniaturized or made more complex.

AI summary
A drill kit includes at least one shaft of a first connection type, each shaft having a different length than each other shaft of the at least one shaft of the first connection type. The drill kit further includes preparation drill bits each having a first connection geometry. The drill kit further includes compression drill bits each having the first connection geometry. Each shaft has a proximal end configured to connect with an actuator instrument and a distal end configured to connect to the first connection geometry of each of the preparation drill bits and to the first connection geometry of each of the compression drill bits. The devices and methods may optimize the ability to choose surgical access and limit needing to handle components for a touchless and more sterile or hygienic procedure and protocol.
