Background Displacement of dental implants into the maxillary sinus is rare, but it primarily occurs in patients with severe pneumatization of the maxillary sinus and/or deficiency of the alveolar process. Some complications such as the infection of the paranasal sinuses and formation of the oroantral fistula can be followed by the displacement of a dental implant. Therefore, the displaced impl...

a 7.5 year-old girl was seeking orthodontic treatment because of severe ectopic eruption of maxillary first permanent molars. it was a rare case that represented approximately horizontal view in panoramic radiograph. the severity of problem was high, but since the patient had maxillary deficiency, it was important to perform the treatment without extraction. treatment began with extraction of u...

OBJECTIVE The aim of this study was to introduce a new method for bilateral distal movement of the entire maxillary posterior segment. CASE REPORT A 17-year-old girl with Class I skeletal malocclusion (end-to-end molar relationships, deviated midline and space deficiency for left maxillary canine) was referred for orthodontic treatment. She did not accept maxillary first premolars extraction....

OBJECTIVES The objective of the present systematic review was to test the hypothesis of no difference in transverse skeletal and dental arch expansion and relapse after segmental Le Fort I osteotomy versus surgically assisted rapid maxillary expansion. MATERIAL AND METHODS A MEDLINE (PubMed), Embase and Cochrane library search in combination with a hand-search of relevant journals was conduct...

Successful replacement of the lost teeth by means of tissueintegrated implants represents a major advance in dentistry. The bone quality and quantity available in the anterior maxilla is often variable, and commonly, there is a deficiency of bone volume. Dentoalveolar defects resulting in the loss of the maxillary anterior alveolar ridge is generally a challenge for clinicians. The aim of this ...

Alveolar bone grafting is a standard method for treating alveolar cleft. To ensure the best outcome, improving the arch form as well as soft tissue quality in the area around the cleft is recommended. In this study, 11 patients who presented with alveolar cleft and collapsed maxillary arch were treated in the following sequence: transpalatal distraction osteogenesis followed by soft tissue surg...
