Introduction: The aim of this study is to examine the effects of changes in some cephalometric values on the changes in facial age and facial aesthetics scores after surgery in patients undergoing orthognathic surgery.
Material And Methods: Preoperative and postoperative photographs of 50 patients who underwent bilateral sagittal split osteotomy and LeFort I osteotomy were evaluated by 189 evaluators. Evaluators were asked to look at the photographs and estimate the age of the patient and give a score between 0 and 10 for facial aesthetics.
Results: The mean age of 33 female patients was 22.84±0.81, while the mean age of 17 male patients was 24.52±1.21. Class 2 and Class 3 patients were affected at varying rates by changes in cephalometric values. There were also differences in the evaluation of full-face photographs and the evaluation of lateral profile photographs. The data obtained as a result of the analysis are summarized in the tables.
Conclusions: Although the data of our present study presents the relationship between facial age and facial aesthetics and cephalometric analysis results with quantitative data, it has been concluded that the evaluation process of these parameters is quite complex and may not yield optimum results in clinical evaluation.

Objective: This study constructed a new conditional generative adversarial network (CGAN) model to predict changes in lateral appearance following orthodontic treatment.
Methods: Lateral cephalometric radiographs of adult patients were obtained before (T1) and after (T2) orthodontic treatment. The expanded dataset was divided into training, validation, and test sets by random sampling in a ratio of 8:1:1.

The nasolabial angle (NLA) is one of the most critical parameters of the soft tissue profile when orthodontic treatment is required. The primary aim of this prospective cohort study was to compare the differences in the evaluation made on lateral photographs and cephalograms. The secondary aim was to evaluate the modifications of the NLA (nasal and labial components) after orthodontic treatment, including upper first premolar extraction.

Objectives: This study aims to compare the effects of two orthodontic treatment modalities for skeletal class Ⅲ malocclusion on specific changes in airway volume, morphology, palatal angle, mandibular rotation, and bone displacement. Results provide scientific evidence for the selection of orthodontic treatment plans and reduce the risk of developing obstructive sleep apnea hypopnea syndrome (OSAHS).
Methods: Thirty-six patients diagnosed with skeletal class Ⅲ malocclusion at the Department of Orthodontics, the Affiliated Stomatological Hospital of Nanjing Medical University from September 2018 to December 2023 were divided into two groups: orthodontic-orthognathic treatment group (18 patients) and camouflage orthodontic treatment group (18 patients).

Twin block appliances are commonly used to treat skeletal class II malocclusion. However, many adverse effects, such as lower incisor protrusion and a bulky nature, can be observed. To overcome these effects, a modified twin block was designed, which uses vacuum-formed hard plates (VFPs) instead of acrylic plates.

Introduction: This randomized clinical trial compared arch dimensional changes, dentoskeletal changes, and the rate of overbite correction in deep bite adults treated with fixed appliances and either maxillary incisor bite turbos (IBT) or canine bite turbos (CBT).
Materials And Methods: Forty-six deep bite subjects treated with fixed appliances were randomized into IBT (n = 23) and CBT (n = 23) groups. Changes in intercanine width (ICW), arch height (AH), and Little's Irregularity Index (LII) were analyzed from before treatment (T) to 3 months after aligning with 0.
