NCT06195761
To assess the accuracy of the computer assessed guides in horizontal bone augmentation achieved at posterior mandible using guided modified ridge splitting technique versus free hand modified ridge splitting technique
NCT06636084
The purpose of this study is to compare alveolar ridge augmentation outcomes of two types of membranes for vertical and horizontal mandibular ridge augmentation: Customized CAD/CAM Titanium Mesh versus Reinforced Perforated PTFE Mesh (RPM).
NCT06529653
The current study aimed to evaluate both the quality and quantity of gained and maintained bone width after ridge splitting utilizing autogenic bone wedges versus mixed bone particles for horizontal ridge augmentation in the anterior esthetic zone.
NCT05311332
this study aims to evaluate horizontal bone augmentation achieved at the anterior maxilla using computer-guided cortical shell bone technique and accuracy of fixation of the bone shell away from the atrophic ridge by a calculated distance which is always a challenging step for inexperienced surgeons to fix a cortical shell at the ideal position in the conventional protocol it was never guided to be precisely fixed at the proper position and angulation the problem is if it fixed with insufficient distance with proposed volume loss leads to totally insufficient volume gain for future implant placement also to evaluate the efficacy of the CAD/CAM surgical guide during chin harvesting procedures in reducing the risk of anatomical structure damage and patient morbidity with more accuracy compared with the standard technique. this trial versus free hand conventional cortical shell bone technique both harvested from symphysis area (chin).
NCT05418452
This study aimed to evaluate the efficacy of 1% metformin gel mixed with PRF, in horizontal ridge augmentation with the split-crest technique, for implant placement.
NCT03153995
The objective of this study will be to assess and compare between sub-periosteal self- inflating osmotic tissue expanders used as preparatory surgery before alveolar ridge augmentation and periosteal releasing incision using autogenous onlay block bone graft. The assessment and comparison will be based on: 1. Change in edentulous alveolar ridge in bucco-lingual dimension after alveolar ridge augmentation. 2. Quantity of the soft tissue obtained after soft tissue expansion.
NCT04376060
The primary aim of this study is to clinically, radiographically and histologically evaluate the lateral bone augmentation of the soft porcine cortical lamina (OsteoBiol®) using equine-derived bone particles (OsteoBiol®)
NCT03635658
this study is aiming to Assess postoperative complications and bone quality and quantity in augmentation of horizontally atrophic maxillary ridge using a 1:1 mixture of autograft and xenograft particulate bone covered with collagen membrane with the new Sausage technique™ versus using the same mixture covered with titanium mesh.
