calcifying epithelial odontogenic tumor is a rare odontogenic neoplasm. its occurrence in the maxillary sinus is very rare. maxillary tumors tend to be locally aggressive and may rapidly involve the surrounding vital structures.  we report a case of calcifying epithelial odontogenic tumor involving maxillary sinus in a 48 years old female patient with the oral mucosal involvement. the purpose o...

introduction: ameloblastic fibro-odontoma is a rare, benign, asymptomatic tumor. the term ameloblastic fibro-odontoma was first used by hooker in 1967 as a separate lesion from ameloblastic odontoma.   case report: this case report describes an eleven years old female with large ameloblastic fibro-odontoma in the right maxillary sinus.   conclusion: there is a low potential for recurrence after...

Background: The thickness of maxillary sinus floor may reduce markedly because of protrusion of root apices of posterior teeth into the sinus. The possibility of oro-antral communication after extraction is highest for a maxillary first molar, as this tooth erupts first and is frequently extracted early. Aim: To assess the relationships between the roots of the maxillary first molar and the max...

AIM The purpose of this study is to evaluate the necessary number of pro-prosthetic interventions in view of the implanto-prosthetic rehabilitation of the defective prosthetic fields. MATERIALS AND METHODS We investigated a lot that included 230 patients aged between 18 and 82 who benefited from implant-prosthetic rehabilitation, the type of graft used, the types of membranes selected as well...

Chronic maxillary atelectasis (CMA) is characterized by a progressive decrease in maxillary sinus volume. The factors that promote the stage progression of CMA remain poorly understood. Here, we describe the time course of anatomical changes in a 40-year-old woman with stage II CMA that progressed to stage III disease. She did not show stage progression until she started to develop repetitive s...

maxillary sinus aplasia and hypoplasia are rare conditions that can cause symptoms such as headaches and voice alteration. the majority of patients are asymptomatic, but these conditions must be noticed for importance of differential diagnosis such as infection and neoplasms. conventional radiographs could not differentiate between infl ammatory mucosal thickening, neoplasm, and hypoplasia of t...

Removal of a maxillary third molar is a common dental procedure, and oral surgeons rarely experience accidental displacement of a maxillary impacted third molar into the maxillary sinus as a complication of this procedure. In the case in which such displacement occurs, the molar is removed via a transantral (Caldwell-Luc) approach through bone removal or window osteotomy of the anterior wall of...
