Digital Facial Analysis for Ideal Upper Front Tooth Shape
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for determining the ideal shape of upper front teeth are limited in accuracy and customization, as they rely on general facial parameters without considering individual facial features and statistical data, leading to suboptimal tooth reconstruction.
Innovation Solution
A new method that uses digital images of the patient's face with specific angles and features to determine ideal points for redesigning the upper front teeth, incorporating facial parameters, original teeth shapes, and statistical data, which can be integrated into software algorithms for precise tooth shape determination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If general facial parameters are used to determine tooth shape, then the method is simple and quick, but the accuracy and customization of tooth reconstruction is reduced
Solution Approach 1:
The method segments the tooth reconstruction process into multiple independent measurement components: facial width measurements, tooth position measurements, and shape parameter calculations. Each component can be measured and processed separately, then integrated to achieve high overall accuracy without requiring a single complex measurement system
Solution Approach 2:
The patent transitions from two-dimensional facial photographs to three-dimensional digital facial models and tooth models. This dimensional enhancement allows for more accurate spatial relationships and geometric calculations, improving tooth shape determination accuracy while providing comprehensive customization options
2Adaptability or versatility
If traditional facial parameter methods are used, then the process is straightforward, but the individualization and natural appearance of reconstructed teeth is compromised
Solution Approach 1:
The method performs preliminary digital scanning and modeling of the patient's existing teeth and facial structure before the actual reconstruction procedure. This preliminary action captures all necessary geometric data and enables virtual trial reconstructions, allowing for high customization without extending the actual treatment time
Solution Approach 2:
The patent creates digital copies of the patient's existing teeth and facial features using 3D scanning technology. These digital copies serve as accurate references for determining the ideal reconstructed tooth shape, enabling precise customization while automating the measurement process to reduce time investment

AI summary
A method for determining and drawing the ideal individual shape of the two front upper teeth uses at least one image of the patient's face in front view, non-smiling and with the mouth closed, and at least one image of the patient's face in front view, smiling and with closed teeth.
