Background This study aimed to analyze the effectiveness of virtually designed polyether‐ether ketone (PEEK) sheets to delineate and maintains the three‐dimensional patient's maxillary alveolar ridge. Materials and methods Fourteen patients (34 implants) with severely atrophied anterior maxillary alveolar ridges underwent rehabilitation using custom‐made CAD/CAM PEEK sheets acting as a containment system for interpositional mix of particulate autogenous and xenogeneic bone graft, fixed by mono‐cortical screws. Radiographic Assessment included measurements of linear changes in the vertical and horizontal dimensions on cross‐sectional cuts of computed tomography (CBCT) using special software. Results Wound healing was uneventful for all the patients except one patient that showed wound break down 2 weeks postoperatively, which did not affect the outcome of the procedure. CBCT scans were interpreted to compare the quantity of both vertical and horizontal bone preoperatively and 6 months postoperatively. Statistical analyses demonstrated a significant difference between the results of both time intervals, with a mean vertical and horizontal bone gain was 3.47 mm(±1.46) and 3.42 (±1.1) with a P‐value of (.0001). The customized sheets were removed 6 months postoperative with the successful placement of dental implants. Conclusion The virtual planning of three‐dimensional maxillary alveolar ridge augmentation utilizing patient‐specific PEEK sheets deemed successful to restore the deficient ridge and to accommodate suitable size dental implants.

Purpose To review the primary additive manufacturing (AM) technologies used to fabricate metals in implant dentistry and compare them to conventional casting and subtractive methods. Methods The literature on metal AM technologies was reviewed, and the AM procedures and their current applications in implant dentistry were collated and described. Collection of published articles about metal AM in dental field data sources: MEDLINE, EMBASE, EBSCO, and Web of Science searched. All studies related to AM technology description, analysis, and evaluation of applications in implant dentistry, including AM titanium (Ti) dental implants, customized Ti mesh for bone grafting techniques, cobalt‐chromium (Co‐Cr) frameworks for implant impression procedures, and Co‐Cr and Ti frameworks for dental implant‐supported prostheses were reviewed. Results Literature has demonstrated the potential of AM technologies to fabricate dental implants, root‐analog implants, and functionally graded implants; as well as the ability to fabricate customized meshes for bone grafting procedures. Metal AM technologies provide a reliable method to manufacture frameworks for implant impression procedures. Co‐Cr and Ti AM frameworks for implant‐supported prostheses provide a clinically acceptable discrepancy at the implant‐prostheses interface. Conclusions Additional clinical studies are required to assess the long‐term clinical performance, biological and mechanical complications, and prosthetic restoration capabilities of additively manufactured dental implants. Moreover, further studies are needed to evaluate their long‐term success and survival rates and biological and mechanical complications of AM implant‐supported prostheses.

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.
