Transparent Braces Planning With Adjacent-Tooth Movement Prediction

Solution Overview

Problem

Existing transparent braces methods fail to accurately account for the indirect effects of adjacent teeth movement during orthodontic treatment, leading to discrepancies between planned and actual treatment results.

Innovation Solution

A transparent braces design method and apparatus that predicts and quantifies the effects of adjacent teeth movement using a color map to adjust the treatment plan, ensuring smooth tooth movement and minimizing discrepancies.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If digital method is used to apply appropriate force to appropriate position on transparent braces, then individual tooth control is improved, but indirect effect of adjacent teeth on the tooth to be moved is not taken into account

Engineering Contradiction:

Improvetooth movement control precisionVSAvoidadjacent teeth indirect effect information

Core Design Contradiction:

Measurement precisionVSLoss of information

Solution Approach 1:

The patent performs preliminary simulation of tooth movement before actual treatment to predict the final position of teeth. The simulation considers not only the direct force applied to the target tooth but also the indirect effects from adjacent teeth, allowing the treatment plan to be adjusted in advance based on predicted outcomes.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements a feedback mechanism where the simulated treatment results are compared with the original treatment plan. Based on this feedback, the treatment plan is modified to account for indirect effects of adjacent teeth, ensuring that the final treatment plan incorporates information about tooth interactions that were initially overlooked.

Inventive Principle:

Principle #23Feedback

2Adaptability or versatility

If transparent braces are manufactured for each stage according to treatment plan, then treatment flexibility is improved, but treatment accuracy may deviate from planned results due to unaccounted adjacent teeth effects

Engineering Contradiction:

Improvetreatment stage adaptabilityVSAvoidtreatment result accuracy
