Multi-Axis Dental Implant Torque Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dental implants have limitations, including a single osseointegration axis and area, leading to gaps between the implant and soft tissue that can cause infections and increased torque on a single point, resulting in implant failure, especially with wider prosthetics.
Innovation Solution
A customizable dental implant design that maximizes osseointegration by using multiple anchor points across multiple axes (X, Y, Z) and a larger surface area, incorporating various osseointegrable materials, and employing a CNC milling process to create a custom fit within the jawbone, reducing gaps and distributing forces more evenly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single titanium screw implant is used, then the implant structure is simple and easy to manufacture, but the osseointegration area is limited and torque concentration leads to implant failure
Solution Approach 1:
The implant is divided into multiple components: a plurality of pins (first, second, third pins) with different orientations, each providing separate anchoring points. This segmentation distributes the load across multiple bone-implant interfaces rather than concentrating torque on a single screw, thereby improving reliability while maintaining manufacturing feasibility through modular design
Solution Approach 2:
The invention transitions from a single-axis (Z-axis only) implant to a multi-dimensional implant system with pins extending along X, Y, and Z axes. This dimensional expansion increases the osseointegration surface area and creates a three-dimensional anchor network within the bone, enhancing mechanical stability and resistance to multidirectional forces
2Device complexity
If a single axis implant is used, then the implant design is simple, but the torque forces are concentrated on a single point causing flexing and potential failure
Solution Approach 1:
The implant structure is segmented into multiple pins oriented along different axes (X, Y, Z), creating multiple fulcrum points. This segmentation distributes torque forces across several anchor points rather than concentrating them on a single screw, reducing flexing and preventing failure while maintaining reasonable geometric complexity
Solution Approach 2:
The multi-axis pin configuration acts as a counterbalancing system where pins in different orientations provide opposing support forces. When torque is applied, the distributed pin network creates counter-moments that balance the applied loads, preventing excessive flexing and protecting the implant-bone interface from failure
3Ease of operation
If a single screw implant is used, then the implant installation is straightforward, but gaps form between the implant and soft tissue leading to infections
Solution Approach 1:
By extending pins along X, Y, and Z axes rather than using a single Z-axis screw, the implant achieves three-dimensional contact with the surrounding bone and soft tissue. This multi-dimensional configuration eliminates gaps between the implant structure and adjacent tissues, preventing food and bacterial accumulation while maintaining straightforward surgical insertion through standardized protocols
4Reliability
If multiple anchor points across multiple axes are used, then the osseointegration surface area is maximized and torque is distributed, but the implant design and manufacturing become more complex
Solution Approach 1:
The complex multi-axis structure is segmented into discrete, standardized pin components that can be manufactured using conventional techniques. Each pin is a simple cylindrical element with threading, but their strategic arrangement along X, Y, and Z axes creates the complex three-dimensional anchor pattern, separating manufacturing simplicity from structural complexity
Solution Approach 2:
Multiple pin elements are merged into a single integrated implant assembly that functions as one unified structure. The pins are positioned and secured together to form a cohesive multi-axis anchor system, combining multiple simple components into a single implant unit that achieves maximized osseointegration without requiring complex individual component design
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances the durability and longevity of dental implants by increasing the osseointegration surface area, reducing infection risks, and distributing torque across a larger volume of bone, thereby improving the stability and lifespan of the implant.
Implementation Method 1
a plurality of bone anchors (410) designed to be forced or pressed into bone to hold the implant firmly in place while healing and osseointegration ensues

AI summary
Customized dental implants feature enhanced osseointegrable qualities by manufacturing the implant post with osseointegrable material and preparing a larger post body, including a portion to cover a maximized prepared bone surface, to integrate with a jawbone. Resultant implants are more durable and provide a better fit into the oral cavity. Various implant shapes and designs are disclosed. A dental implant may feature a plurality of bone spikes to serve as anchors for the implant in a patient's mouth. Multiple anchors lessen torques experienced by the implant during use. Ideally, the anchors will also project in different axes to maximize osseointegration and strength of the bond between bone and the implant.
