Osteo-implant Bone Healing Chamber Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bone screws and artificial dental implants require extensive parameterization design, which is time-consuming and often results in unfit implants due to varying bone conditions and bite forces among patients, leading to reduced bone integration ratios and increased surgical failure rates.
Innovation Solution
The osteo-implant features a fixing segment with a thread and at least one bone healing chamber located at the thread root, where the section area of the bone healing chamber decreases gradually towards the implant end, optimizing bone healing and integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If parameterization design is used to optimize bone screw or artificial dental implant, then the fitting precision is improved, but the design time is significantly increased
Solution Approach 1:
The patent applies parameter changes by systematically varying geometric parameters of the implant (thread pitch, diameter, chamber dimensions, depth, and distribution) to optimize both fitting precision and healing acceleration. The fixing segment includes multiple parameters such as thread pitch (0.5-2.0mm), outer diameter (3.0-6.0mm), and bone healing chamber dimensions that can be adjusted to match different patient bone conditions and bite forces, thereby achieving high fitting precision without requiring exhaustive parameterization design for each case.
2Loss of time
If a universal implant design is applied to all patients, then the design time is reduced, but the bone integration ratio is reduced due to varying bone conditions and bite forces
Solution Approach 1:
The patent applies local quality by creating regions with different properties within the same implant. The fixing segment contains bone healing chambers with varying dimensions, depths, and distributions along the implant length, allowing different sections to serve different functions: some regions prioritize bone ingrowth while others provide structural support. This local differentiation enables the universal implant to adapt to varying bone conditions and bite forces across different patient anatomies, maintaining high bone integration ratios without requiring custom design for each patient.
3Reliability
If the bone healing chamber area is increased to accelerate bone healing, then the bone integration ratio is improved, but the supporting strength of the implant is reduced
Solution Approach 1:
The patent resolves this contradiction through parameter optimization by establishing specific ranges for bone healing chamber dimensions and their spatial distribution. The chamber diameter is controlled at 0.2-0.8mm with depth at 0.5-2.0mm, and the pitch between chambers is maintained at 0.3-1.5mm. These parameter ranges are designed to provide sufficient surface area for bone ingrowth while maintaining adequate structural integrity. The thread parameters (pitch, diameter, depth) are also optimized to compensate for the material removed by chambers, ensuring both bone integration and supporting strength are achieved simultaneously.

AI summary
An osteo-implant is provided, having a fixing segment and an implant end. The fixing segment is provided with a thread and at least one bone healing chamber. The bone healing chamber is located at a thread root of the thread. The bone healing chamber is a chamber inwardly depressed from a surface of the fixing segment. The fixing segment has a central axis. In the same section of the fixing segment, an area of a section, which is parallel to and passes through the central axis, of the at least one bone healing chamber closer to the implant end is smaller.
