Effects of Pterygomaxillary Separation on Skeletal and Dental Changes After Surgically Assisted Rapid Maxillary Expansion: A Single-Center, Double-Blind, Randomized Clinical Trial.

Purpose: Surgically assisted rapid maxillary expansion (SARME) is a procedure routinely performed to correct transverse maxillary deformities and can be performed with or without pterygomaxillary disjunction (PD). The aim of the present study was to measure the effect of the amount of expansion and stability of SARME with or without PD.

Patients And Methods: We designed and implemented a double-blind, randomized clinical trial.

Use positional screws for Le Fort I osteotomy fixation: technical note.

In recent years, several studies related to fixation systems have been published, but few suggest any variations of the Le Fort I osteotomy technique, and the use of plates and screws placed along the canine and zygomatic pillar are common. The 20-year-old patient with Crouzon syndrome presented with severe hypoplasia of the maxillary, mandibular prognathism, and class III facial pattern. The patient underwent orthognathic surgery and high Le Fort I osteotomy with the fixation of eight positional screws.

Sagittal osteotomy for the removal of deeply impacted mandibular molars: a presentation of series of cases.

Sagittal osteotomy was primarily described as a treatment for prognathism and retrognathia. It has been rarely reported as an option for the removal of deeply impacted tooth. The principal indication of this approach is when the tooth is deeply impacted on the mandibular ramus or body and it presents intimate relationship between its root and inferior alveolar neurovascular bundles.
