Stepped Dental Implant Drill and Fixture Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dental implant procedures require a multi-step process using multiple drill bits of different diameters, making the process time-consuming, costly, and increasing patient anxiety and the risk of drill failure.
Innovation Solution
A quick dental implant kit featuring a drill bit with stepped cutting edges and a fixture with a long arc-shaped contour, allowing for the drilling of a single stepped hole in the jawbone, reducing the need for multiple drill bits and simplifying the procedure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple drill bits of different diameters are used to drill a hole in the jawbone, then the hole can be drilled to the required size, but the process becomes time-consuming and increases treatment cost
Solution Approach 1:
The drill bit is divided into multiple cutting edges with different diameters along its length, allowing it to perform multiple drilling functions in a single operation. The drill bit includes a first cutting edge with a first diameter and a second cutting edge with a second diameter, enabling sequential drilling of different hole sizes without changing tools.
Solution Approach 2:
The drill bit is designed to perform multiple functions - drilling holes of different diameters - within a single tool. This multi-functional design eliminates the need for a set of separate drill bits, reducing both time and cost while maintaining the precision required for different hole sizes.
2Manufacturing precision
If multiple drill bits of different diameters are used, then the required hole size can be achieved, but the device complexity and preparation cost increase
Solution Approach 1:
Multiple drill bits that would traditionally be separate tools are merged into a single integrated drill bit. The combining of different cutting edges with different diameters into one tool reduces device complexity, eliminates the need for multiple separate bits, and simplifies the overall drilling system while maintaining the precision of individual hole drilling.
3Manufacturing precision
If multiple drill bits are used in sequence, then the hole can be drilled to the required size, but the probability of drill failure increases
Solution Approach 1:
The drill bit is designed with larger diameter cutting edges positioned to engage the bone first, creating an initial cavity that guides and stabilizes subsequent drilling with smaller diameter cutting edges. This preliminary action with the larger cutting edge establishes a reliable starting point that reduces the risk of failure during the drilling process.

AI summary
A quick dental implant kit includes a fixture having an upper fine thread portion, a lower coarse thread portion and a diameter gradually reducing in direction from the top side toward the bottom side and exhibiting a long arc-shaped contour, and a drill bit having a shank connectable to and rotatable by a dental handpiece and a stepped cutter body formed integral with the bottom end of the shank and defining a plurality of stepped cutting edges for drilling a stepped hole in a jawbone of a patient for the implant of the fixture. Each stepped cutting edge defines at least five steps and at least four risers alternatively connected in a longitudinal series to fit the long arc-shaped contour of the fixture.
