RIDGE PRESERVATION COMPARING THE CLINICAL AND HISTOLOGIC HEALING OF AN INTRASOCKET ALLOGRAFT VS. A FACIAL OVERLAY XENOGRAFT USING A BIORESORBABLE BARRIER MEMBRANE Evmenios Poulias, DDS September 17th, 2012 Aim. The efficacy of ridge preservation procedures using grafting materials and barrier membranes has been well established in the literature. However, the loss of horizontal width even with the utilization of intrasocket only guided bone regeneration procedures can lead to loss of soft and hard tissue contour or even compromise implant placement. The primary aim of this study was to compare ridge preservation using an intrasocket mineralized particulate cancellous allograft to an intrasocket mineralized particulate cancellous allograft plus a facial overlay with a particulate bovine xenograft, both covered with a bioresorbable barrier membrane. Clinical and histologic data was used to assess the outcomes. Methods. Twelve positive controls received an intrasocket mineralized cancellous particulate allograft 500-800 flm (lntrasocket group) while twelve test patients received an intrasocket mineralized cancellous particulate allograft 500 to 800 flm plus a facial overlay with a particulate bovine xenograft 250-1000 flm (Overlay group).

متن کاملClinical, Histologic and Histomorphometric Evaluation of Bone Strip Allograft with Resorbable Membrane in Horizontal Alveolar Ridge Augmentation: A Preliminary Study
Objective: Alveolar ridge preservation in patients with inadequate bone volume is one treatment option for successful implant placement and can be done by using bone graft materials. On the other hand, Ceno Bone has been recently produced by Hamanand Saz Baft Kish Co. as a bone bioimplant of allograft origin. This study aimed to assess the clinical, histologic and histomorphometric results of...

PURPOSE The aim of this randomized, controlled, blinded clinical study was to compare ridge dimensions and histologic characteristics of ridges preserved with 2 different graft materials. MATERIALS AND METHODS Twenty-four subjects, each requiring a nonmolar extraction and delayed implant placement, were randomly selected to receive ridge preservation treatment with either an allograft in an e...
متن کاملClinical and Histological Comparison of Extraction Socket Healing Following the Use of Autologous Platelet-Rich Fibrin Matrix (PRFM) to Ridge Preservation Procedures Employing Demineralized Freeze Dried Bone Allograft Material and Membrane
BACKGROUND The healing potential of platelet growth factors has generated interest in using Platelet-Rich Plasma (PRP) in ridge preservation procedures. A canine study was performed to determine if extraction sites treated with platelet-rich fibrin matrix (PRFM) exhibit enhanced healing compared to sites treated with non-viable materials. METHODS Four dog's extraction sockets were treated ind...
متن کاملHistological Comparison of Healing Following Tooth Extraction With Ridge Preservation Using Mineralized vs. Demineralized Freeze Dried Bone Allograft
Background: Allografts such as demineralized freeze-dried bone allograft (DFDBA) and mineralized FDBA are commonly used by clinicians for ridge preservation procedures. The primary objective of this study is to histologically evaluate and compare the healing of non-molar extraction sockets grafted with DFDBA vs. FDBA for ridge preservation. The secondary aim of this study is to compare dimensio...
