Sinus Membrane Elevation Drill Set with Guide Bushing Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During dental implant procedures, particularly sinus membrane elevation, existing drilling techniques face challenges in accurately measuring depth and direction, leading to potential damage of the sinus membrane tissue due to inadequate support and vibration of drilling tools, especially in cases with limited bone availability or narrow oral cavities.
Innovation Solution
An implant set device comprising a drill group with varying effective diameters and lengths, including initial, dilatation, sinus, and final drills, along with a guide stent and guide bushing, to ensure precise drilling and prevent sinus membrane damage by providing stable support and intuitive drill selection based on pre-determined effective lengths and diameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an auxiliary stopper is inserted into the outer circumference surface of a drill guide to adjust insertion depth, then the insertion depth can be adjusted, but the outer circumference surface of the guide is not firmly supported by the guide stent during drilling
Solution Approach 1:
The patent introduces a guide bushing as an intermediary component between the drill guide and the guide stent. The guide bushing fits into the guide hole of the guide stent and provides a stable support surface for the outer circumference of the drill guide, ensuring firm support during drilling while allowing precise insertion depth adjustment through the auxiliary stopper mechanism.
2Measurement precision
If the cutting portion of a drill is made long to use an auxiliary stopper, then the auxiliary stopper can be used for depth control, but the cutting portion becomes more susceptible to vibration or deformation
Solution Approach 1:
The guide bushing acts as a mediator that provides lateral support to the drill's outer circumference surface during the drilling process. This support prevents vibration and deformation of the cutting portion, allowing the use of longer drills with auxiliary stoppers for precise depth control without compromising cutting portion stability.
3Measurement precision
If a drill is inserted in a cutting direction with a long auxiliary stopper being interposed for narrow oral cavity structures, then the auxiliary stopper provides depth control, but there is difficulty in securing space in the vertical direction
Solution Approach 1:
The guide bushing provides a stable support structure that allows the drill with a long auxiliary stopper to be properly positioned and supported during insertion. This makes the drilling operation feasible even in narrow oral cavity structures by providing the necessary vertical space and stability.
4Reliability
If a practitioner keeps strongly pressing a drill and auxiliary stopper towards a guide stent to maintain support, then the drill remains supported, but the operation becomes more difficult and the risk of sinus membrane damage increases
Solution Approach 1:
The guide bushing serves as a passive support structure that maintains drill support without requiring strong manual pressure from the practitioner. The drill guide with outer circumference surface fits into the guide bushing, which is already securely positioned in the guide stent, providing automatic support that reduces operational difficulty and minimizes the risk of sinus membrane damage.
