Sequential Sinus Lift Drill Bits for Crestal Membrane Elevation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sinus lift procedures for dental implants are cumbersome, painful, and risky due to lateral approaches or vertical knocking techniques, leading to prolonged surgery, discomfort, and high chances of sinus membrane perforation.
Innovation Solution
A set of serial drill bits with different configurations and sizes is used to drill an implant hole vertically via the alveolar crest, ensuring safe and comfortable surgery by sequentially elevating the sinus membrane without perforation, using a universal connection with a motor driving device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If lateral approach is used to lift sinus membrane, then sinus membrane can be accessed, but surgical time is prolonged and surgical complexity increases
Solution Approach 1:
The patent inverts the conventional lateral approach by using a vertical approach through the alveolar crest. Instead of accessing the sinus membrane laterally through extensive flap elevation, the drill bit approaches the sinus membrane vertically from the crestal direction, dramatically reducing surgical time and complexity while achieving the same goal of membrane access and elevation
2Reliability
If vertical knocking technique is used to lift sinus membrane, then membrane can be elevated, but patient discomfort and anxiety increase
Solution Approach 1:
The patent replaces the mechanical knocking action with a controlled rotational drilling action. Instead of using osteotomes to knock and break bone (which causes palpable impacts and jarring noise), the drill bit gradually removes bone through rotation, eliminating the harmful mechanical impacts that cause patient anxiety and discomfort while achieving the same membrane elevation effect
3Ease of operation
If conventional drill bits are used for sinus lift, then implant hole can be drilled, but risk of membrane perforation increases
Solution Approach 1:
The patent applies local quality by designing drill bits with specific configurations tailored for sinus lift procedures. The drill bits have optimized geometries including progressive diameter reductions and specific fluting patterns that enable controlled bone removal while minimizing lateral forces on the sinus membrane, thereby reducing perforation risk while maintaining ease of operation
Solution Approach 2:
The patent uses a set of serial drill bits with progressively smaller diameters. The larger diameter drill bits are used first to create the initial implant hole and elevate the membrane, then progressively smaller drill bits are used to refine the hole and further elevate the membrane. This preliminary action with larger bits creates initial membrane elevation that protects against perforation during subsequent drilling with smaller bits
