Sinus Dental Implant with Stepped Drilling Segments for Controlled Cutting
Solution Overview
Problem
Conventional sinus dental implants tend to idle in the alveolar hole without further cutting when in contact with the bottom, risking injury to the sinus membrane due to excessive force application.
Innovation Solution
The sinus dental implant features a drilling end with spiral cutting flutes and drilling segments of varying heights, allowing for gradual cutting and preventing excessive penetration, while maintaining contact with the alveolar hole bottom.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the conventional sinus dental implant uses horizontal drilling segments at the same level, then the structure is simple, but the implant idles in the alveolar hole without cutting further when contact with the bottom
Solution Approach 1:
The drilling zone is divided into multiple drilling segments with different height levels. Each drilling segment has a different axial position, creating a stepped structure that allows sequential engagement with the bone at different depths, preventing idle rotation and enabling continuous cutting progress.
Solution Approach 2:
The invention transitions from a two-dimensional horizontal drilling segment configuration to a three-dimensional stepped configuration with varying axial heights. This dimensional change allows the drilling segments to engage the bone at different depths, creating a progressive cutting action that eliminates idling.
2Productivity
If the dentist applies more force to drive the drilling end through the bottom, then the implant can penetrate further, but the sinus membrane may be injured
Solution Approach 1:
The stepped drilling segments create a dynamic, progressive cutting action where each segment engages the bone at a different stage of penetration. This dynamic engagement distributes the cutting force over time and depth, allowing controlled progression through the bone bottom without sudden force spikes that could injure the sinus membrane.
Solution Approach 2:
The invention changes the geometric parameters of the drilling segments by varying their axial heights. This parameter variation creates a stepped configuration that modifies the force distribution and cutting progression, enabling safe penetration through the bone bottom while controlling the maximum force applied at any single moment.
3Ease of manufacture
If the drilling segments are at the same level, then the manufacturing is easy, but the implant cannot cut and move further when in contact with the bottom
Solution Approach 1:
The drilling zone is segmented into multiple levels with different axial heights. This segmentation creates a stepped structure that maintains manufacturing feasibility through standard machining processes while enabling progressive cutting action that continues through the bone bottom without idle rotation.

AI summary
A sinus dental implant includes a main body, an external thread, and a plurality of spiral cutting flutes. The main body has opposite connection end and drilling end. The drilling end has a centered recess surrounded by a drilling zone and communicable with the spiral cutting flutes. The external thread and the spiral cutting flutes are extended in two different spiral directions. The drilling zone is divided by the spiral cutting flutes into a plurality of drilling segments, each of which has two sides located at different heights to thereby include a lower and an upper drilling portion. When the sinus dental implant is implanted into an alveolar hole to contact with a bottom thereof, the lower drilling portions at the drilling end cut the bottom of the alveolar hole slowly, so that the sinus dental implant can drill further in the alveolar hole instead of idling therein.
