Dental Implant Fixture With Continuous Thread And Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dental implant fixtures require additional drilling when switching to a different size, leading to cumbersome operations and potential misalignment or damage to the alveolar bone during implantation.
Innovation Solution
The development of an implant system with first and second fixtures featuring continuous spiral thread parts and bone damage prevention parts, allowing for direct implantation of a second fixture without additional drilling and preventing misalignment and bone damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different-sized fixtures are used for implantation, then the implant can be adapted to different patient needs, but additional drilling and drill selection is required which complicates the procedure
Solution Approach 1:
The patent applies universality by designing fixtures with standardized body dimensions and thread specifications that allow a single drill size to be used across multiple fixture variants. Different fixture sizes achieve adaptability through modular design elements rather than requiring different drilling operations, simplifying the overall implantation process while maintaining versatility.
Solution Approach 2:
The fixture design segments the threading portion from the body portion, allowing the threaded section to vary in diameter while the body and drilling requirements remain standardized. This segmentation enables size adaptability in the implantation interface without affecting the drilling and insertion process.
2Strength
If thread part is formed on the entire outer surface of the fixture body, then firm coupling with alveolar bone is achieved, but bone damage occurs in the opening area during implantation
Solution Approach 1:
The patent applies local quality by creating a non-threaded region at the opening area of the fixture body where the outer surface is smooth, while maintaining threaded portions in other areas for bone coupling. This localized differentiation protects the alveolar bone during implantation in the opening area while preserving firm coupling strength in the threaded regions.
3Ease of operation
If cutting edge portion is formed by discontinuing the thread part, then fixture implantation is facilitated, but misalignment with desired implantation direction occurs
Solution Approach 1:
The patent applies preliminary action by forming a guide portion at the opening area that extends in the desired implantation direction before the threaded coupling portion. This guide portion is prepared in advance to establish correct alignment, and the threading is then formed to follow this predetermined direction, ensuring both ease of insertion and precise alignment.

AI summary
Disclosed are a fixture for a dental implant and an implant system comprising the same. The implant system of the present inventive concept comprises: a first fixture having a first body part and a first continuous screw part which is formed in a spiral around the outer circumferential surface of the first body part and is formed continuously without a break; and a second fixture having a second body part that is identical to the first body part, and a second continuous screw part which is formed in a spiral around the outer circumferential surface of the second body part and which has an outer diameter that differs from that of the first continuous screw part. The present inventive concept allows implant operations to be carried out in a more straightforward fashion than hitherto since, even if initial fixture placement fails, a subsequent fixture can be placed straight away without any further drilling work.
