Background: Soft tissues play the primary role of physical appearance and facial esthetics. This study aimed to establish soft-tissue cephalometric standards in North Indian adults, which can be used in diagnosis, treatment planning, and stability of orthodontic outcome and orthognathic patients.
Materials And Methods: A group of 60 individuals (30 males and 30 females) with normal occlusion and proportional facial profile were chosen. For the entire chosen sample, lateral cephalograms were obtained. Standard values of 11 soft-tissue measurements were determined.
Results: Soft-tissue measurements showed that men had greater soft-tissue facial angle (92.10°) than women (89.92°). Also, they had more nose prominence (18.10 mm) than women (16.44 mm). Skeletal profile convexity (A to N-pog) of men (0.40 mm) was less than women (1.76 mm). Basic upper lip thickness was higher in men (16.60 mm) compared to women (14.24 mm), while H-angle was higher in women (16.68°) as compared to men (14.30°). In the lower face area, inferior sulcus to the H line distance was more in men (7.30 mm) than women (4.80 mm). Men had greater soft-tissue chin thickness (14.10 mm) than women (12.84 mm).
Conclusion: The differences in soft-tissue cephalometric norms between men and women of North Indian faces were established, so the orthodontist or surgeon must individualize treatment planning, using local norms as the reference.

Objectives: To investigate whether extractions in adult anterior openbite (AOB) patients lead to improved treatment outcomes and better short-term stability.
Materials And Methods: Records of extraction (EXT) and nonextraction (NE) adult patients were identified from all patients treated with fixed appliances through the National Dental Practice-Based Research Network. Photographic Openbite Severity Index was used to assess treatment success and stability.

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 non-randomised clinical study aimed to identify the phenotypic characteristics that distinguish responders from non-responders. Additionally, it sought to establish a predictive model for treatment response to obstructive sleep apnoea (OSA) using mandibular advancement devices (MAD), based on the analysed phenotypic characteristics.
Material And Methods: This study, registered under identifier NCT05596825, prospectively analysed MAD treatment over 6 years using two-piece adjustable appliances according to a standardised protocol.

Objective: To determine the effect of the nose and chin on the cephalometric lip profile.
Methods And Material: The pre-treatment lateral cephalograms of 177 adult patients with no history of orthodontic treatment were manually traced. The sample size was divided into three vertical and horizontal groups using angle ANB and MMA to assess the difference in nose and chin forms.
