Filter by:Bone healing after tooth extraction may be affected by defects in the buccal wall of the alveolus, such as fenestrations and dehiscences. Therefore, it is advisable to perform a surgical procedure such as guided bone regeneration after tooth extractions. Different biomaterials are used for this purpose. The aim of this study is to investigate the qualitative and quantitative histological changes in human biopsies taken after 6 months of healing of extraction sockets with buccal wall defects. For this purpose, the defects of 36 patients (18 per group) will be augmented with injectable biphasic calcium phosphate (I-BCP) or bovine xenograft (BX) after extraction. After six months of healing, bone biopsies will be taken and processed to the qualitative and quantitative histological analysis.
The primary objective of this study was to compare the efficacy of using allograft, autogenous tooth graft, and beta-tricalcium phosphate for alveolar ridge preservation (ARP) by examining the alveolar ridge height and width at baseline and 3 months after the ARP both clinically and radiographically. The secondary objective was to evaluate the quality of the newly formed bone using histomorphometric analysis.
Thirty-six patients (19 females and 17 males) that required implant placement in esthetic zone participated in this study and were blindly allocated 12 patients per group, all patients had ARP either with I-PRF with xenograft, HA with xenograft or xenograft alone, the sockets were sealed with free gingival graft harvested from the palate.
The aim of this study is to compare two pre-prosthetic surgical techniques for augmentation of vertical mandibular ridge defects in preparation for implant placement, the first using customized ceramic membranes and the second using tenting titanium screws in conjunction with particulate bone graft and collagen membrane (modified sausage technique).
