Background: This study evaluates implant-borne prosthetic rehabilitation of 10 totally edentulous atrophic maxillae after bone reconstruction with a titanium-mesh technique and particulate bone graft. Methods: Ten atrophic maxillae were reconstructed with 19 titanium meshes and particulate autologous-heterologous bone. Maxillae were rehabilitated at least 5 months, with placement of 67 implants connected to the prostheses after an additional 4 months of rehabilitation. Cases were evaluated retrospectively in terms of complication rates, particularly on the amount of mesh exposure, implant survival, and success rates at the end of follow-up. Results: In seven cases, two meshes were prematurely exposed (within 4 to 6 weeks), and five were exposed later (after 4 to 6 weeks). Only two of the later exposures extended >1 cm2. Nevertheless, reconstructions allowed implant placement and prosthetic rehabilitation in all cases. Two implants were lost before loading. After mean follow-up at 39.3 (20 to 56) months since prosthetic loading, all 65 implants were functional (100% implant survival), but 15 implants demonstrated a peri-implant mean bone resorption of 2.96 mm increased bone loss, yielding a cumulative implant success rate of 76.9%. No prosthetic problem was observed. Conclusions: Use of titanium mesh with particulate bone can be considered a valid option in reconstructing atrophic maxillae to allow for implant-borne prosthetic rehabilitation. A high level of dehiscence did not compromise final outcome.
