A 19-year-old woman with skeletal Class III malocclusion, paranasal depression, and a low mandibular plane angle was treated with orthodontics and orthognathic surgery. Dental decompensation and protraction of maxillary right third molar to replace maxillary right second molar were performed before surgery. Clockwise rotation of maxillo-mandibular complex was applied by Le Fort I osteotomy and bilateral sagittal split osteotomies to achieve facial balance. The active treatment period was 12 months. The stable occlusion and skeletal relationship were observed after a 10-month follow-up period.

Objective: The aim of this retrospective study was to compare the effects of the Twin block and Herbst appliances on the mandibular trabecular pattern using fractal dimension analysis (FDA) of panoramic radiographs (PRs).
Methods: The PRs of 50 subjects with skeletal Class II malocclusion who underwent the Twin block (T-group, average age: 11.63±0.

The aim of this paper was to systematically review and compare the Apnoea-Hypopnoea Index (AHI), Lowest O Saturation (LSAT), Oxygen Desaturation Index (ODI), Epworth Sleep Scale (ESS), and Body Mass Index (BMI) between dentofacial (skeletal) classes I, II, and III before and after maxillomandibular advancement (MMA) for Obstructive Sleep Apnoea (OSA). The PubMed, Scopus, and CINAHL databases were searched from inception to 23 November 2022. Two reviewers screened for articles that reported occlusion/malocclusion class type as I, II, or III, and reported preoperative and postoperative AHI, LSAT, ODI, ESS, and/or BMI.

Background: Orthodontic treatment involves manipulation of tooth position that can temporarily lead to occlusal interferences capable of inducing bruxism. The objectives of this study were to determine the self-reported incidence of bruxism and its association with factors such as facial type, divergence, skeletal and dental malocclusions in orthodontic patients.
Materials And Methods: 80 patients who underwent a minimum of six months of orthodontic treatment were surveyed using a validated self-reported bruxism questionnaire for the presence or absence of bruxism.

Importance: The incidence of potentially inappropriate medication (PIM) prescribing among older adults is not as well studied as its prevalence. Estimates of factors associated with PIM incidence, such as patient age, sex, race-ethnicity, medication subsidy support, and comorbidity, are also limited.
Objective: To estimate the incidence of PIM prescribing in older adult outpatients, as well as the incidence and predictors for each PIM class, in a large outpatient electronic health records (EHR) cohort.

As maxillofacial surgery becomes increasingly digitized and the transformative impact of pre-surgical scanning and computer simulation is recognized, this clinical paper presents an algorithm for the selection of interventions in severe congenital oligodontia with Angle class-III malocclusion (OCIII) utilizing such technologies. A complex, multifactorial condition with varying degrees of craniofacial involvement, OCIII is associated with edentulous facial appearance, mandibular prognathism and deep underbite, as well as malocclusion. Our methodology involves the integration of CBCT imaging, intra- and extra- oral scanning, and 3D planning with the assessment of bone volume, number of missing teeth, skeletal discrepancies, and patient compliance in the selection of suitable treatments.
