Interdental Filler Model Generation for Orthodontic Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Interdental gaps between teeth can cause discomfort and reduce the effectiveness of orthodontic appliances, as they can lead to bending or deformation and lack of support when wearing orthodontic devices like aligners.
Innovation Solution
A method and system for generating interdental filler models using a computing system to create a 3D representation of a surface that fills the gap between teeth, which can be used to manufacture orthodontic appliances with integrated interdental fillers, reducing discomfort and improving appliance effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If orthodontic appliances are worn by patients with interdental gaps, then the treatment can proceed, but the appliance experiences bending or deformation and provides insufficient support
Solution Approach 1:
The patent applies preliminary action by generating a virtual model of the interdental filler before manufacturing the actual orthodontic appliance. The system creates a 3D digital representation of the gap between teeth, determines the optimal shape and size of the filler, and prepares the model in advance. This allows the appliance to be designed with the filler already integrated, ensuring proper support and fit before the treatment begins.
2Ease of operation
If orthodontic appliances are worn by patients with interdental gaps, then the treatment can proceed, but the patient experiences discomfort
Solution Approach 1:
The patent applies local quality by focusing on the specific interdental gap region rather than modifying the entire appliance. The system generates a filler model that is precisely tailored to fit the gap between two specific teeth, with customized dimensions and curvature. This localized approach ensures that the filler provides the necessary support and comfort in the gap area without affecting the overall appliance design, thereby improving patient comfort while maintaining reliable fit.
3Ease of manufacture
If an automated or semi-automated system is used to generate interdental filler models, then the manufacturing process is improved, but the system complexity increases
Solution Approach 1:
The patent applies copying by creating a virtual 3D digital model of the interdental filler before producing the physical appliance. The system captures the geometry of the interdental gap and generates a digital representation that can be manipulated, analyzed, and approved before manufacturing. This virtual copy allows for automated generation and optimization of the filler design, simplifying the manufacturing process while reducing the need for complex manual modeling operations.

AI summary
Methods, systems, and apparatuses are described for generating an interdental filler model for a patient. Locations for ends of the interdental filler model may be determined. A curvature of the interdental filler model may be determined. A shape of the interdental filler model may be determined. A first arc may be determined for a first end of the interdental filler model and a second arc may be determined for a second end of the interdental filler model. A set of arcs may be interpolated between the first arc and the second arc. The set of arcs may be grounded on the patient's gingiva. The interdental filler model may be generated based on the set of arcs.
