Obstructive sleep apnea (OSA) can be a debilitating, even life-threatening, condition. The most favorable treatment for patients with OSA is multidisciplinary care by a team that represents various dental and medical disciplines. Prescribed therapies might include weight loss, behavior modification, oral appliances, soft tissue surgery, skeletal surgery, or some combination of approaches. When orthognathic surgery has been used, often only the anteroposterior dimension is addressed, and the transverse dimension is overlooked. The treatment presented here demonstrates the important role that transverse expansion of the maxillary and mandibular arches can have for patients with severe OSA. An initial stage of maxillary and mandibular transverse distraction osteogenesis was performed, followed immediately by fixed orthodontic treatment. After appropriate orthodontic alignment, leveling, and coordination, a second surgical stage consisting of maxillary and mandibular advancement was performed. Marked enhancements in occlusion and facial morphology, and a profound improvement in the OSA, were obtained.

A calcifying epithelial odontogenic tumour (CEOT) is a rare benign odontogenic tumour of epithelial origin accounting for approximately 1% of all odontogenic tumours. The intraosseous form occurs more commonly in the posterior mandible whereas the extraosseous form is common in the anterior maxilla. CEOT is often asymptomatic and presents with a painless swelling of the mandible.

Objectives: This study determined the prevalence and risks of definite sleep bruxism (SB) among children and adolescents presenting for orthodontic treatment.
Methods: This was a cross-sectional study of 7-16-year-old subjects pursuing orthodontic treatment for the first time. The presence or absence of SB was determined using an overnight mandibular movement monitoring inertial measurement sensor, worn by each participant for two consecutive nights.

The posterior mandible is the primary area for occlusal function. However, long-term tooth loss in the posterior mandible often leads to rapid absorption of both buccal and lingual trabecular bone plates and subsequent atrophy of the alveolar ridge. This ultimately results in horizontal bone deficiencies that complicate achieving an optimal three-dimensional placement for dental implants.

Aims And Background: The study of the morphology of soft tissues as well as hard tissues of the orofacial region holds prime importance. A very less information is known about the lips (soft tissues) and maxillo-mandibular arches (hard tissue structures) in primary dentition. Henceforth, there is a need to classify, find the prevalence and correlation of various lip shapes, and arch forms in primary dentition.

Introduction Unilateral cleft lip and palate (UCLP) often leads to maxillary hypoplasia and skeletal Class III malocclusion, with conflicting evidence on mandibular asymmetry. This study evaluated vertical mandibular asymmetry in UCLP patients, comparing them with non-cleft individuals having skeletal Class III and Class I malocclusions. Methods Mandibular asymmetry was evaluated using orthopantomograms (OPGs) from 90 subjects divided into three groups of 30 each: UCLP group, non-cleft skeletal Class III, and non-cleft skeletal Class I.
