Prediction of Aerodynamic Characteristics in Upper Airways with Lateral Cephalograms [PDF]

, 2021
Abstract Background: The lateral cephalogram is a common imaging diagnostic test for adenoid hypertrophy (AH) in clinics. The study aims to investigate the aerodynamic characteristics within the upper airway (UA) by employing a computational fluid dynamics (CFD) simulation.

Evaluation of Autoregressive Models for Predicting Two‐Dimensional Mandibular Landmark Displacement During Pubertal Growth

Orthodontics &Craniofacial Research, EarlyView.
ABSTRACT Objectives To predict mandibular landmark displacement during pubertal growth using autoregressive models. Materials and Methods The study included 225 subjects with complete cephalometric radiographs from ages 10 to 18. Data were split by subject into training (180; 83 males, 97 females) and test sets (45; 21 males, 24 females).

Artificial Intelligence in Orthodontics: A Scoping Review of Methods and Applications

Orthodontics &Craniofacial Research, EarlyView.
ABSTRACT The rapid integration of artificial intelligence (AI) into orthodontics raises important questions about which methods are being applied, how they are being validated, and what barriers remain to clinical implementation. This study was conducted to inform orthodontic practitioners, researchers, and educators about the possibilities that AI ...
