Accurately estimating treatment length and identifying cases likely to finish very early or require extended time can significantly enhance treatment planning and patient communication. This study aimed to develop and compare machine learning (ML) models for predicting continuous orthodontic treatment duration and for classifying short-duration (≤12 months) and long-duration (≥30 months) treatments using a large, diverse clinical dataset.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;A total of 10,553 completed orthodontic cases were extracted from 120,000 records in the FMBO database. Seventy percent of the data was used for training and 30% for testing. Seven regression algorithms (Linear Regression, OLS, Bagging, Random Forest, Gradient Boost, AdaBoost, XGBoost) were evaluated. Classification models (Logistic Regression, Random Forest, Gradient Boost, XGBoost, AdaBoost, Bagging) were developed to identify short and long treatments. Class imbalance was addressed using class weighting and optimized probability thresholds (0.24 for short, 0.16 for long). Model performance was assessed using MSE, &lt;i&gt;R&lt;/i&gt; &lt;sup&gt;2&lt;/sup&gt;, precision, recall, F1-score, confusion matrices, and AUC.

The most influential predictors across regression models were age at treatment start, extraction plan, facial convexity, skeletal pattern, overjet, and overbite.
