Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional sinus implants often inadvertently enter the sinus cavity during dental implant procedures in the maxilla area, particularly with short implants, due to their traditional structure.

Innovation Solution

A sinus implant system featuring a sinus implant with overlapping cylindrical structures of different diameters, accompanied by a drill and port graft apparatus that prevent implant intrusion into the sinus cavity by drilling and grafting bony tissue to secure the implant in place.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional structure sinus implants are used, then the implant can be applied to the maxilla area, but the implant may inadvertently enter the sinus cavity

Engineering Contradiction:

Improveimplant placement accuracyVSAvoidsinus cavity intrusion

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The implant is divided into two distinct cylindrical portions: a first cylindrical portion that remains outside the sinus bottom and a second cylindrical portion that penetrates into the sinus bottom. This segmentation allows each portion to serve its specific function while preventing the entire implant from entering the sinus cavity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The second cylindrical portion is positioned concentrically within the first cylindrical portion, creating a nested structure. The smaller diameter of the second portion relative to the first ensures that even as the implant penetrates the sinus bottom, the outer boundary is controlled and prevents sinus cavity intrusion

Inventive Principle:

Principle #7Nested doll (Nesting)

2Stability of the object's composition

If the implant penetrates into the sinus bottom, then bony tissue integration is facilitated, but the implant may get into the sinus cavity

Engineering Contradiction:

Improvebony tissue integrationVSAvoidsinus cavity intrusion

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

Different portions of the implant have different diameters tailored to their specific functions: the first cylindrical portion has a larger diameter to maintain stability outside the sinus, while the second cylindrical portion has a smaller diameter to safely penetrate and integrate with the sinus bottom bone tissue without entering the sinus cavity

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The drill apparatus is designed with a cutting portion that drills the sinus bottom to a predetermined depth and diameter matching the second cylindrical portion of the implant. This preliminary preparation ensures that when the implant is inserted, it integrates with the bone tissue at the correct depth without penetrating into the sinus cavity

Inventive Principle:

Principle #10Preliminary action
