Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current orthodontic attachment systems face challenges in accurately determining the optimal coupling point on teeth for orthodontic attachments, leading to potential discomfort and inefficiency in orthodontic treatments due to the complexity of tooth configurations and the need for precise force application.
Innovation Solution
A computer-implemented method and system that utilize digital 3D representations of teeth to identify excluded areas and determine a coupling point by analyzing various excluded zones, such as those related to contact with opposing or neighboring teeth, gum lines, and appliance edges, ensuring accurate attachment placement and force distribution.

1Measurement precision
If conventional attachment placement methods are used, then attachment can be applied to teeth, but accurate determination of optimal coupling point is difficult leading to discomfort and treatment inefficiency
Solution Approach 1:
The patent uses digital 3D representations (virtual copies) of teeth to determine coupling points without requiring complex physical measurement devices. The system creates a digital model of the patient's dentition and performs all coupling point determinations in the virtual space, then transfers the results back to the physical attachment placement process.
Solution Approach 2:
The patent replaces complex mechanical measurement and positioning systems with computer-based image processing and automated algorithms. Instead of using physical calipers, gauges, and manual positioning devices, the system uses digital 3D scanning and software-based coupling point determination to achieve higher precision with reduced complexity.
2Manufacturing precision
If multiple excluded areas are analyzed to determine coupling point, then attachment placement accuracy is improved, but computational complexity increases
Solution Approach 1:
The patent divides the tooth surface into multiple excluded areas (gingival excluded area, occlusal excluded area, proximal excluded area) that can be independently analyzed and combined. Each excluded area is determined by specific criteria and represented as a separate region in the digital model, making the complex determination process manageable through systematic segmentation.
Solution Approach 2:
The patent performs preliminary determination of all excluded areas before finalizing the coupling point selection. The system pre-calculates gingival excluded areas, occlusal excluded areas, and proximal excluded areas based on digital 3D representations, then uses these pre-determined regions to identify the optimal coupling point, streamlining the overall process.
3Productivity
If automated coupling point determination is implemented, then treatment efficiency is improved, but requirement for digital 3D representation and processing increases
Solution Approach 1:
The patent uses a universal digital 3D representation system that serves multiple functions: it enables coupling point determination, facilitates treatment planning, supports attachment design, and aids in manufacturing. This single digital model replaces multiple separate measurement and planning processes, improving efficiency while consolidating rather than increasing complexity.

AI summary
Method for determining a coupling point for an attachment on a tooth of a subject comprising: obtaining a digital 3D representation of the tooth to which the attachment will be coupled; obtaining attachment data indicative of the attachment to be coupled to the tooth; determining, on the digital 3D representation of the tooth, a plurality of excluded areas for the coupling point based on the digital 3D representation of the tooth and the attachment data; determining the coupling point by identifying an area on the tooth which is not in the plurality of excluded areas; and storing, in a memory of the computer system, the determined coupling point.
