Purpose The aim of this study was to evaluate the efficacy of autologous intraoral onlay bone grafting ( OBG ) in correlation with long‐term survival rates of dental implants placed in the augmented bone. Materials and Methods A retrospective study was conducted on 214 patients who received a total of 633 dental implants placed in 224 autologous intraoral block OBG augmentations, combined with B io‐ O ss – mixed with platelet‐rich plasma ( PRP ) and covered by platelet‐poor plasma ( PPP ) – as scaffold, with a follow‐up time up to 137 months (mean 39.9 ± 30.9 months). Results A total of 216 OBG cases were successful (96.4%), and most of the augmentations were uneventful (88.4%). Bone graft exposure was moderately associated with bone graft failure (χ 2 = 3.76, p = .052). The healing period after implant placement was 4–6 months (mean 5.6 ± 2.56). The majority of the 591 implants survived (93.4%). The cumulative survival rate of the implants was 83%. Conclusions We suggest that augmentation of severely atrophied jaw bone through the placement of horizontal and/or vertical intraoral OBG s in combination with B io‐ O ss saturated with PRP and covered by PPP should be considered a reliable, safe, and very effective surgical technique for obtaining high bone graft survival rate and high long‐term implant survival rate.
