Rotary Bone Powder Propelling Bit for Dental Implant
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bone powder filling tools for dental implants are inefficient, requiring excessive time and physical effort, causing discomfort to patients and strain on medical professionals due to their slow and laborious operation in increasing cortical bone thickness for tooth implantation.
Innovation Solution
A bone powder filling tool with a rotary dental instrument-connected handle and a bone powder propelling bit featuring spirally extending grooves and threads around its periphery, designed to rapidly and uniformly fill bone powder between the sinus floor and cortical bone, reducing the need for manual force and shortening procedure time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional bone powder filling tool with a pushing needle is used, then the tool structure is simple, but the filling operation is hard and slow, increasing operation time and physical effort
Solution Approach 1:
The patent replaces the manual pushing needle mechanism with a rotary drilling mechanism that utilizes rotational mechanical energy to propel bone powder. The bone powder propelling bit rotates to automatically feed and push bone powder into the cortical bone area, converting manual linear pushing into automated rotational feeding, thereby reducing operational effort and increasing filling speed
Solution Approach 2:
The patent introduces a dynamic rotating bone powder propelling bit that can rotate during the filling operation. This dynamic element allows the bone powder to be continuously fed and propelled through rotation, enabling rapid and uniform filling without requiring sustained manual pushing effort, thus resolving the contradiction between filling speed and operational effort
2Loss of time
If a conventional pushing needle tool is used, then the device complexity is low, but the operation time is increased and patient discomfort is prolonged
Solution Approach 1:
The patent replaces the simple manual pushing mechanism with a rotary drilling system that uses rotational motion to rapidly fill bone powder. This mechanical substitution dramatically reduces operation time by automating the bone powder feeding process through rotation, justifying the increased device complexity with significant time savings
Solution Approach 2:
The bone powder propelling bit serves multiple functions: it drills into the cortical bone, feeds bone powder through its grooves, and propels the powder into the target area through rotation. This multi-functionality consolidates multiple operations into a single tool, reducing overall procedure time despite increased device complexity

AI summary
A bone powder filling tool includes a handle connectable to a rotary dental instrument, and a bone powder propelling bit located one end of the handle. The bone powder propelling bit has opposing top end portion and bottom end portion, bone powder transferring grooves spirally extending around the periphery thereof from the top end portion to the bottom end portion, and bone powder propelling threads extending around the periphery thereof at different elevations for rapidly and uniformly propelling bone powder into the space between the sinus floor and the cortical bone to increase the thickness of the cortical bone in favor of the process of the subsequent tooth implanting, helping the doctor in charge of the operation save operating time and physical strength.
