“…This is in accordance with a 15-year follow-up by JeMT and JOHANSSON 14 who found similar long-term success rates after implant treatment in the edentulous maxillae in nongrafted patients. A survey of the literature on similar grafting technique as in the present study, reports survival rates varying from 49 to 95% 15,22,26,27,29,32 . The time in long-term follow-up studies varies from 12 to 124 months 26 ; only one study covered a minimum of 10 years 22 .…”

“…25,26 Soft tissue closure poses a limitation for reconstruction of the severely atrophic maxilla. In a review article, 22 partial loss of the graft because of wound dehiscence/infection occurred in 3.3% of the cases, whereas total loss of the graft occurred in 1.4% of the cases, 27,28 the majority being related to extensive reconstructions of the atrophic maxillae with iliac grafts. The overall survival rate of implants placed in conjunction with onlay bone graft was 79.5% (range, 60%-100%).…”

Purpose The severely atrophic edentulous maxilla imposes a challenge for dental implant rehabilitation. Nasal floor augmentation (NFA) is a method of augmenting bone height in the anterior maxilla. Autogenous bone has been commonly used as a graft material. Because of variations in results and lack of insufficient studies reporting the use of bone substitutes to graft the nasal floor, this study aims to evaluate the survival and success of dental implants placed in nasally grafted maxillae with osteoconductive bone substitutes. Materials and Methods Six patients with completely edentulous maxillae and inadequate height in the anterior to support implants underwent NFA. The nasal floor was exposed through an intraoral approach and grafted with osteoconductive bone graft substitutes. Twenty-four dental implants were placed, restored with a bar-retained implant-supported overdenture after a traditional healing period, and followed up after prosthetic loading. Patient satisfaction was evaluated with a questionnaire, and responses were expressed on a visual analog scale from 1 to 10. Bone levels were quantified radiographically based on a score ranging from 1 to 3, where 3 represented the highest bone support. Implants were evaluated for thread exposure and soft tissue health and were considered successful if the following criteria were met: absence of mobility; lack of symptoms; bone score of 3; and healthy peri-implant soft tissue without thread exposure. Results The age of patients ranged from 48 to 84 years, with a mean of 71.2 years. Three patients underwent NFA and simultaneous implant placement, whereas the other 3 had a mean healing period of 6.5 months before implant placement. Post-loading follow-up ranged from 4 to 29 months, with a mean of 14.2 months. The implant survival rate was 100%, with no complications. Ninety-three percent of the responses to the treatment satisfaction questionnaire had a score of 7 or greater. Bone scores ranged from 2 to 3, with 87.5% of implants having a score of 3 and 12.5% having a score of 2. None of the implants had a bone score of 1. Conclusions The use of osteoconductive bone substitutes for NFA, as shown in this small case series, is a reliable method for reconstruction of the anterior atrophic maxilla for implant-supported overdentures.

“…While the success rates of the sinus floor elevation vary between 76 and 100% and 48 and 100% of all alveolar crest onlay augmentations seem to be successful concerning implant survival. In these studies, however, it is difficult to compare the outcome of the applied techniques: Primary and secondary implant insertion were carried out, autogenous bone and bone substitutes were used, and different periods of observation have been compared with different methods 3,7,9,19,20,22,23,25,26 .…”
