Early treatment for Class II malocclusion was undertaken with the objective of correcting skeletal disproportion by altering the growth pattern. A case of Class II, Division 1 malocclusion in the mixed dentition was corrected to Class I molar relationship using orthopedic cervical headgear, with nonextraction edgewise therapy. Cephalometric analysis indicated a reduction in the maxillomandibular discrepancy (ANB) correcting the Class II malocclusion to Class I malocclusion. The treatment showed that this was achieved by downward displacement and inhibition of the forward growth of the maxilla and growth of the mandible. There was no downward rotation of the mandible nor maxillary first molar extrusion. There was improvement in the jaw relationship.

The aim of this study was to determine the effects of mandibular setback surgery exceeding 5 mm on upper airway and sleep quality in skeletal Class III patients, with comparisons to Class I controls. Sixteen individuals per group were selected based on their ANB angle and surgical need. 2D and 3D airway analyses were conducted.

Background: Gingival recession defects (GRDs) pose functional and esthetic concerns and may be associated with unfavorable tooth positions. Surgically facilitated orthodontic treatment (SFOT) with clear aligners can be a valuable option for adults with severe malocclusion and GRDs.
Methods: A 28-year-old male presented with severe dental crowding, Class III dental malocclusion, localized tooth crossbites, and tapered maxillary arch.

This case report presents the multidisciplinary treatment of a male patient with a complex form of frontonasal dysplasia who presented with a 0 to 14 facial cleft, mild hypertelorism, absence of the nasal medial process of the nose, and frontonasal encephalocele. Cranial and plastic surgeries were performed to correct hypertelorism and improve the esthetic appearance of the frontonasal region. In the permanent dentition, the patient presented a Class II, division 1 malocclusion with severe maxillary constriction and bilateral posterior crossbite.

This study aimed to assess the changes in the position and size of articular spaces and anteroposterior and mediolateral condyle dimensions following orthognathic surgery. Additionally, it evaluated the correlation between these changes and mandibular movement during surgery. This experimental study examined 31 patients (16 with Class III and 15 with Class II malocclusions) who were candidates for orthognathic surgery.

Introduction: This study aimed to evaluate the stability of palatal rugae patterns after slow maxillary expansion (SME) treatment and the reliability of the rugae region as a reference region in digital superimposition.
Methods: The SME group comprised 21 subjects with Angle Class I or Class II dental malocclusion with unilateral or bilateral crossbite and constricted maxilla and were selected before the pubertal peak. Intraoral scans were captured via the intraoral scanner iTero Element software (version 1.
