Evaluation of the Regenerative Capacity of Demineralized Bone Matrix vs Fat Graft in Alveolar Cleft Model in Albino Rats.

Aim: This study was performed to evaluate the regenerative capacity of demineralized bone matrix vs fat graft, both guided by pericardium membrane in alveolar cleft model in albino rats.

Materials And Methods: A total of 72 rats were required in this study. A surgical bone defect with a 7 mm length × 4 mm width × 3 mm depth was created as a model of an alveolar cleft, then the rats were divided randomly into four equal groups each group contained 18 rats: control group (defect only), the membrane group (the defect was covered by the pericardium membrane), the demineralized bone matrix (DBM) group (the defect was filled with DBM guided by pericardium membrane) and fat group (the defect was filled with a fat graft guided by the pericardium membrane).

The Effect of Topical Application of Hyaluronic Acid on the Stability of Immediate Loaded Dental Implants in the Posterior Maxilla: Clinical and Animal Study.

To assess the effect of topically applied hyaluronic acid (HA) on the stability of immediately loaded implants in the posterior maxilla. For the clinical study, a total of 20 implants were placed in 14 patients seeking the replacement of missing single or multiple posterior maxillary teeth. The patients were randomly divided into two groups.

Evaluation of Two Computerized Methods for Presurgical Volumetric Analysis in Secondary Alveolar Cleft Bone Grafting: A Prospective Study.

Aim: The purpose of this study is to evaluate presurgical computerized volumetric analysis in secondary alveolar cleft bone grafting (SABG) and the time taken for calculation using cone-beam computed tomography (CBCT) via two different software programs.

Materials And Methods: Twelve patients with unilateral alveolar clefts were investigated using CBCT. Two independent investigators did presurgical volumetric analysis for each patient's CBCT data using two different methods.
