Orthodontic Bone Screw Plate with Elastic Fixing Members
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional orthodontic treatment methods require multiple bone screw implantations for severely misaligned teeth, making the procedure complex, painful, and risky, while also failing to efficiently apply torque forces to individual teeth.
Innovation Solution
An orthodontic correction device with a bone screw plate and elastic member that allows for adjustable corrective forces, reducing the need for multiple bone screw implants by applying forces in various directions, including torque, and positioning the device on the palatal side to minimize dental root damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If multiple bone screws are implanted for severely misaligned teeth, then the corrective force can be applied to multiple teeth, but the surgical complexity and risk increase
Solution Approach 1:
The patent combines multiple bone screw fixation functions into a single integrated bone screw device. The device includes a bone screw with a head portion that can simultaneously engage multiple elastic fixing members, each connecting to different teeth. This merging approach allows corrective force to be applied to multiple teeth through one implantation procedure, reducing surgical complexity while maintaining effective force application.
Solution Approach 2:
The bone screw device is designed with multi-functionality to handle various orthodontic correction needs. The head portion can accommodate different types and numbers of elastic fixing members, allowing the same device to apply corrective forces to different teeth configurations. This universal design enables a single device to replace what would traditionally require multiple specialized bone screws.
2Force
If multiple bone screws are implanted, then corrective force can be applied to multiple teeth, but the treatment time and patient discomfort increase
Solution Approach 1:
By merging multiple fixation functions into one bone screw device, the treatment procedure is streamlined. The single implantation procedure reduces surgical time compared to multiple separate bone screw implantations. The device can engage multiple elastic fixing members simultaneously, allowing corrective force to be applied to multiple teeth in one procedure rather than requiring sequential treatments.
3Force
If conventional bone screw device is used, then simple pulling force can be applied, but torque force cannot be applied to individual teeth
Solution Approach 1:
The device incorporates dynamic adaptability through its elastic fixing members and positioning portions. The elastic fixing members can be engaged at different positions on the bone screw's neck portion, allowing the direction and type of force (pulling or torque) to be adjusted based on individual tooth correction needs. This dynamic configuration enables the same device to provide both pulling forces and torque forces as required.
Solution Approach 2:
The bone screw device features local quality variations through its structured design. The neck portion has specific geometric features (such as ridges or positioning portions) that allow selective engagement of elastic fixing members at different locations. This localized structural variation enables different force applications (pulling vs. torque) on different teeth connected to different parts of the same bone screw device.
4Force
If multiple bone screws are implanted, then corrective force coverage is improved, but the risk of dental root damage increases
Solution Approach 1:
By consolidating multiple fixation points into a single bone screw device with multiple elastic fixing members, the number of implantation sites is reduced from multiple to one. This merging approach maintains comprehensive force coverage across multiple teeth while minimizing the number of times the surgical instrument penetrates the jawbone, thereby reducing the cumulative risk of dental root damage.

AI summary
The present invention provides an orthodontic correction device that is set up within an oral cavity of a patient. The orthodontic correction device includes a bone screw plate that has a plate, wherein the plate includes at least a positioning portion, and a surface of the plate includes at least a fixing member; at least a bone screw that is in connection with at least a positioning portion of the bone screw plate, and that is fixed by implanting into the oral cavity of the patient; at least a base body that is assembled on a surface of the teeth and including a connecting portion; and at least an elastic member, wherein a fixing end of the elastic member is assembled and fixed on the fixing member of the bone screw plate, a functioning end of the elastic member is in mutual connection with the connecting portion of the base body, and an orthodontic correction force is formed between the fixing end and the functioning end. As such, the orthodontic correction force applied to the teeth of the patient may enable the arrangement of the patient's teeth to be corrected.
