Bone Distraction Bar with Swivel Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bone distraction methods lack flexibility, predictability, and cost-effectiveness, making it challenging to achieve desired bone and soft tissue contours for dental restorations, particularly in remodeling jawbone ridges for dental restorations such as bridges or crowns.
Innovation Solution
A device comprising a bar with a first connection interface for attaching to bone fixtures and a second connection interface for a level adjustment device, allowing for precise control and flexibility in bone distraction, along with a kit of components and method for forming the device, enabling predictable bone distraction and restoration of jawbone ridges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional bone distraction methods are used, then the procedure can be performed, but the flexibility and predictability in achieving desired bone contours are insufficient
Solution Approach 1:
The distraction device is divided into multiple independent components: a bar element, a level adjustment device with swivel mechanism, and threaded engagement parts. This segmentation allows each component to be optimized independently and assembled in different configurations to achieve various distraction patterns and bone contours.
Solution Approach 2:
The level adjustment device incorporates a swivel mechanism that allows dynamic adjustment of the bar's orientation and angle during the distraction procedure. This dynamic capability enables the surgeon to adapt the distraction vector in real-time to achieve the desired bone contour with high predictability.
2Manufacturing precision
If custom distraction devices are designed for each patient, then precision is improved, but cost and complexity increase
Solution Approach 1:
The distraction device employs universal connection interfaces with standardized threaded engagement parts that can accommodate different bar configurations and adjustment requirements. This multi-functionality allows a single basic device design to serve multiple patient-specific needs through different assembly configurations rather than requiring completely custom devices.
Solution Approach 2:
The device includes pre-configured threaded recesses and engagement parts that are prepared in advance during manufacturing, allowing for rapid patient-specific customization through simple assembly rather than complex fabrication. The level adjustment device is pre-assembled with the swivel mechanism, reducing surgical complexity.
3Ease of manufacture
If simple distraction devices are used, then cost is reduced, but the ability to achieve well-defined bone endpoints is limited
Solution Approach 1:
The level adjustment device acts as an intermediary mechanism between the fixed bar element and the moving distraction components. This intermediate swivel mechanism provides precise angular control and position adjustment, enabling well-defined bone endpoints without requiring complex custom fabrication, thus maintaining cost-effectiveness.

AI summary
A device, kit, and method are provided for distracting bone. The device can comprise a bar and at least one connection interface. For example, the bar can comprise a first connection interface configured for releasable connection of the bar to at least one fixture inserted in a bone portion to be distracted. A second connection interface can be configured to connect the bar to a level adjustment device for distracting the bone portion.
