Abstract
Aim: This study was designed to compare between the use of Khoury's bone shell technique vs titanium-reinforced PTFE membrane for 3D-ridge augmentation of atrophic posterior mandible.
Materials and methods: Sixteen patients were equally and randomly assigned to either the Khoury or PTFE group. In Khoury group, a mandibular bone block was harvested, split and then fixed to augment the mandibular defect using osteosynthesis screws. In PTFE group, augmentation was achieved using Titanium-reinforced PTFE membranes fixed with bone tacks/screws. A mixture of autogenous and xenogenic graft material at a 1:1 ratio was used in both groups. Vertical and horizontal bone gain were obtained using cone-beam computed tomography (CBCT). Preoperative dimensions were compared with the final dimensions obtained 6 months postoperatively.
Results: No significant complications or neurosensory dysfunction were encountered. A solitary patient in the Khoury group experienced limited wound dehiscence, which was treated conservatively. For both groups, there were no significant differences between preoperative and postoperative vertical (p = 0.849 and 0.569) and horizontal (p = 0.778 and 0.367) dimensions.
Conclusion: No significant differences exist between the augmentation dimension which can be obtained using either Khoury of Ti-PTFE membranes.
Clinical significance: Both approaches are delicate and necessitate surgical expertise and experience. Both techniques can be used to achieve predictable augmentation results with a low rate of complications. How to cite this article: Shaker AES, Salem AS, El-Farag SAA, et al.

期刊介绍：
The Journal of Contemporary Dental Practice (JCDP), is a peer-reviewed, open access MEDLINE indexed journal. The journal’s full text is available online at http://www.thejcdp.com. The journal allows free access (open access) to its contents. Articles with clinical relevance will be given preference for publication. The Journal publishes original research papers, review articles, rare and novel case reports, and clinical techniques. Manuscripts are invited from all specialties of dentistry i.e., conservative dentistry and endodontics, dentofacial orthopedics and orthodontics, oral medicine and radiology, oral pathology, oral surgery, orodental diseases, pediatric dentistry, implantology, periodontics, clinical aspects of public health dentistry, and prosthodontics.
