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.EnglishOctober University for Modern Sciences and Artsجامعة أكتوبر للعلوم الحديثة والآدابUniversity of Modern Sciences and ArtsMSA Universitybone augmentationCAD-CAMmeshpatient specificPEEKtitaniumetherether derivativeketonetitaniumalveolar bonealveolar ridge augmentationbone transplantationcontrolled studycross-sectional studyhumanmaxillarandomized controlled trialsurgical meshtooth implantationAlveolar ProcessAlveolar Ridge AugmentationBone TransplantationCross-Sectional StudiesDental Implantation, EndosseousEtherEthersHumansKetonesMaxillaSurgical MeshTitaniumArticlehttps://doi.org/10.1111/cid.12748PubMed ID : 30895678
