The objective of the research was to evaluate the distribution of stress produced by surgically assisted rapid maxillary expansion in the maxillary structures using the bone-supported expander device by the Finite Element Method. Material and methods: A three- dimensional model was simulated for surgery with a LeFort I osteotomy with pterygomaxillary disjunction using a bone-supported device model for the 1mm a...

Although various theories such as trauma and infection have been proposed, it is difficult to establish the pathogenesis of osteoma. Osteomas may be detected with routine radiographic examination or the tumors may enlarge and cause symptoms. O...
The main objective of the surgically assisted rapid maxillary expansion (SARME) is to increase the transversal dimension of the upper dental arch in individuals with maxillary atresia. Its effects are not restricted to the maxilla, also acting on the nasal cavity and pharyngeal airway. The present study aimed to evaluate the occurrence of dimensional changes in the nasal cavity and nasal and upper pharyngeal ai...
The maxillary sinuses are the largest of the paranasal sinuses. They consist of pneumatized bilateral cavities, lined by respiratory mucosa, identical to the nasal mucosa, consisting of pseudostratified epithelium, with hair cells and goblet cells, producing mucus. Radiographically, the maxillary sinus is seen as a radiolucent area, ovoid or rounded, with a well-defined contour, delimited by a continuous radiop...
