Abstract
ABSTRACT:
Purpose: To evaluate maxillary sinus and alveolar crest dimensional changes after posterior maxillary tooth extraction, using bovine bone graft (Bio-Oss®) and platelet-rich fibrin membrane for ridge preservation. Patients and methods: Twenty-four patients were selected from those attending outpatient clinics of the Department of Oral and Maxillofacial Surgery, Faculty of Dentistry for boys Al-Azhar University, presented with maxillary posterior molar indicated for extraction. All selected patients randomly allocated into two equal groups. group one is a Study group, extraction one of maxillary posterior teeth with application of Bio-Oss® and platelet-rich fibrin membrane for ridge preservation. Group two is a Control group, extraction one of maxillary posterior teeth without any grafting material. The measurements were performed includes: distance from the bone crest (BC) to the sinus floor (SF), distance from SF to the sinus roof (SR) to evaluate maxillary sinus and alveolar crest dimensional changes after posterior maxillary tooth extraction in both groups. Results: There was statistically significant decrease in alveolar ridge height (BC to SF) and significant increase is sinus vertical dimension (SF to SR) for both groups. while there is a significant increase of bone quantity in the study group than the control group. Conclusion: It can be concluded that tooth extraction in the posterior maxilla may lead to sinus pneumatization and crestal bone loss, using Bio-Oss® and platelet-rich fibrin seemed to reduce sinus pneumatization along with minimizing crestal bone resorption.
