Materials and Methods for Model Development

This study looked into using an AI-ML model as a Clinical Decision Support System (CDSS) in orthodontics. It used 700 case records with clinical data, cephalometric data, and treatment plans from orthodontists. The data was split into a training set and a test set, 70:30.

Sample Selection and Data Collection

The study analyzed 42 cephalometric features from patient anatomy for the models. It went through steps like data cleaning, selecting features, adapting models, and checking their performance. This was done using cephalometric features and expert scores.

Model Architecture and Training

The model was built with a basic outline of orthodontic diagnosis and treatment planning. It had input layers with common variables and an output layer with the diagnosis and treatment type. The model used expert orthodontists’ data to learn.

First, it diagnosed skeletal jaw bases I, II, and III. Then, it predicted treatment modes for each skeletal class. This made the treatment planning more accurate.

Model	Accuracy F1 Score
Layer 1 (Skeletal Jaw Diagnosis)	84.93%
Layer 2 (Treatment Mode Prediction for Skeletal Class I)	82.22%
Layer 3 (Treatment Mode Prediction for Skeletal Class II)	81.51%
Layer 4 (Treatment Mode Prediction for Skeletal Class III)	87.08%

The best machine learning algorithms, eXtreme Gradient Boosting (XGB), Random Forest (RF), and Decision Tree (DT), were the most accurate. The overall model was about 84% accurate.

“The use of AI and ML in orthodontic treatment planning has the potential to enhance quality management and save time in diagnostic procedures, ultimately improving the efficiency and accuracy of the treatment process.”

Discussion of Findings

This study shows how machine learning can improve orthodontic treatment planning. It used a mix of clinical, photographic, and cephalometric data. This mix helped train the models better than earlier studies that only used cephalometric data.

The accuracy of the models, from 87% to 90%, was higher than before. Earlier studies used Artificial Neural Networks for specific decisions. But this study looked at more aspects of treatment planning.

This makes the results more valuable. Using different types of data makes the models better at predicting treatment plans. This leads to more tailored treatment for patients.

Factors Influencing Treatment Plan Prediction

Researchers are working hard to improve orthodontic treatment planning with machine learning predictive models. They want to know what makes treatment plan predictions accurate.

Correlation Analysis of Input Parameters

The team looked into how patient traits affect treatment results. They used a heat map and regression analysis to see how different factors connect to the treatment plan.

They also found out which factors matter most for predicting treatment plans. By listing the top ten factors, they learned what really guides treatment decisions.

This deep dive showed how things like age, gender, crowding levels, and planned tooth movements affect treatment outcomes. With this knowledge, doctors can make better treatment plans for each patient.

“By uncovering the critical factors that shape orthodontic treatment predictions, we can enhance the accuracy and effectiveness of our decision-making processes, ultimately leading to better outcomes for our patients.”

This machine learning research in orthodontics highlights the importance of data in planning treatments. As technology advances, these methods will change how we give personalized and effective orthodontic care.

Potential Applications and Limitations

This machine learning model could be a big help in orthodontics as a Clinical Decision Support System (CDSS). It’s very good at making treatment plans, just like experts. It could help less experienced orthodontists make better and more consistent choices.

But, there are some downsides to the model. The data used to train it is big, but it could get even better with more examples. Also, there’s a risk of bias in the data that needs to be looked at and fixed.

Adding more details like what the patient wants, their economic status, and other health info could make the model even better. This would help it give more complete advice on treatment plans.
