    Background: Alveolar bone grafting techniques and dental rehabilitation of patients with maxillary alveolar defects is a very challenging and costly procedure. Various methods have been described to reconstruct these defects in order to facilitate the placement of dental implants. The aim of this study was to assess three dimensional (3D) maxillary ridge augmentation using two innovative, accurate, and time saving protocols. Materials and Methods: Sixteen patients (32 implants) with vertically and horizontally deficient maxillary alveolar ridges, were equally allocated into 2 groups; a mix of particulate autogenous and xenogenic bone grafts loaded in a prebent titanium mesh (Control group) vs patient specific poly-ether-ether ketone meshes (Study group). Radiographic assessment was performed preoperatively, 1 week and 6 months postoperatively. Assessment included measurements of linear changes in the vertical and horizontal dimensions on cross sectional cuts of cone beam computed tomography using special software. Finally; the percentage of 3D bone gain in each group was compared to that of the other. Results: Wound healing was uneventful for all cases except one patient in each group were the meshes were exposed 2 weeks' postsurgery. There was no statistical significance between both groups (P value = 0.2). Conclusion: Within the limitations of the sample size of this study, both techniques could be used as a successful method of ridge augmentation with no statistical significance between them. � 2019 Wiley Periodicals, Inc.

    Assessment of vertical ridge augmentation in anterior aesthetic zone using onlay xenografts with titanium mesh versus the inlay bone grafting technique: A randomized clinical trial

    The aim of this study was to evaluate the final vertical gain at the deficient anterior maxillary alveolar ridges using onlay bone grafts with titanium mesh versus inlay bone grafting. This was a single institutional randomized comparative clinical trial. The study population included 16 patients, with edentulous anterior maxillary alveolar ridges (40 implant sites) who were presented and treated at the Faculty of Oral and Dental Medicine in Cairo University from September 2013 to August 2015. Selected patients were randomly divided into two equal groups. The control group received onlay particulate xenograft together with titanium mesh as a space-maintaining device while the study group received inlay block xenograft (sandwich osteotomy) fixed with mini-plates. Assessment using cone beam computed tomography (CBCT) included the mean percentage of vertical gain at the proposed implant sites after 6 months taken from cross-sectional cuts. A total of 40 delayed implant placements were done. Results showed that there was no statistical significance between the two groups (P = 0.2); the mean percentage of 6 months postoperative vertical bone gain in the control group was 20.7% and that in the study group was 31.6%. 2017 International Association of Oral and Maxillofacial Surgeons
