Inadequate maxillary incisor display can negatively impact facial esthetics. Various treatment options exist depending on the underlying cause and severity of the condition. Skeletal anchorage was used to extrude the maxillary dentition and rotate the mandible backward, enhancing visibility of the maxillary incisors. An extrusion assembly was introduced to achieve orthodontic extrusion. Use of bite raisers and interarch elastics was also discussed. Treatment results demonstrated successful achievement of the treatment goals. In addition to optimal occlusion, the patient's facial profile improved with increased lip fullness. There was an increase in vertical facial height, and maxillary incisor display was significantly improved, resulting in a more pleasant smile. Two-year postretention records evidenced the stability of total arch extrusion to improve maxillary incisor display.

Background And Objectives: The present study aims to assess and compare the accuracy of post-space impressions captured by three different intraoral scanners (IOS) using various canal diameters.
Methods: Three extracted natural maxillary central incisors were selected and prepared for a 1 mm wide margin and a 3 mm ferrule. All steps required for the endodontic procedure were performed, and the post space was prepared using post drills.
Comparative study of torque expression and its biomechanical effects: spherical self-ligating bracket with lock-hook system versus passive self-ligating bracket and conventional bracket.

Background: Proper torque control is crucial to the outcome of orthodontic treatment. This study aimed to employ finite element analysis to compare the torque capabilities of a novel spherical self-ligating bracket with a lock-hook system against those of commonly used passive self-ligating and conventional bracket systems, as well as to reveal the biomechanical changes in the periodontal ligament (PDL) during torque expression.
Methods: A maxillary right central incisor, along with its PDL and alveolar bone, were modeled.

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.
Normative Palatal Measurements in Infants: Implications for Nasoalveolar Molding in Cleft Lip and Palate Patients.

Department of Otolaryngology-Head and Neck Surgery, Medical University of South Carolina.
Background: Children with cleft lip ± palate (CL/P) may undergo nasoalveolar molding (NAM) before surgery to achieve arch alignment and tension-free closure, yet the endpoint of arch dimensions has not been defined.
Objective: To characterize the size and shape of infant palates using anatomic landmarks on magnetic resonance imaging in infants without CL/P.
Methods: Magnetic resonance imaging of infants without cleft palate younger than 3 months were reviewed and 13 measurements were taken to define palatal shape: distance between incisive foramen (IF) and incisors (IN), IF and middle of canines (MOC), between MOCs, between first molars (FM), 2 depth and 4 angle measurements.
