Osteotome Sinus Floor Elevation without Grafting: A 10‐Year Prospective Study

Abstract

Background:Little is known about the long-term outcome of implants placed in the atrophic maxilla using osteotome sinus floor elevation (OSFE) without grafting.

Long‐term stable vertical bone regeneration after sinus floor elevation and simultaneous implant placement with and without grafting

“…The present study overall mean VBG of 7.7 ± 1.6 mm, 8.5 ± 1.9 for the grafted group, at approximately 65 months indicates predictable and stable long‐term outcomes. Similar 10‐year stable outcomes on a group of 15 patients with mean RBH of 5.4 ± 2.3 and intra‐sinus bone gain of 3.0 ± 1.4 have been recently reported . None of the 17 implants placed in RBH ≤4.8 mm failed in the present study.…”

“…Recent meta‐analysis on graft‐free sinus elevation shows that mean vertical bone gains are low (3.8 mm) and the wide range of vertical gains, 1.8‐7.9 mm, implies inconsistent outcomes . Intra‐sinus bone gain occurs primarily during the first 3 years after sinus elevation and seems to stabilize over time . The present study overall mean VBG of 7.7 ± 1.6 mm, 8.5 ± 1.9 for the grafted group, at approximately 65 months indicates predictable and stable long‐term outcomes.…”

Long‐term evaluation of osteotome sinus floor elevation and simultaneous placement of implants without bone grafts: 10‐Year radiographic and clinical follow‐up

“…Several studies have shown the long‐term outcome and clinical success of placing dental implants in the posterior maxilla using the osteotome technique . Ferrigno and colleagues evaluated the cumulative survival rate and success rates in 588 ITI implants inserted using osteotome technique with bone grafting.…”

Improvements in the Crestal Osteotome Approach Have Decreased the Need for the Lateral Window Approach to Augment the Maxilla

“…Maintenance of the space created after membrane elevation may be important for bone formation to occur (15)(16)(17)(18)(19)(20). The decision to use an osteotome method via the crestal approach allows elevation of the membrane with or without graft placement, which can result in adequate bone function for long-term implant success (7).…”

“…Crestal approach with graft placement: There are studies (18,23,24) that evaluated augmentation of the ridge using allograft and xenograft, with "bone" gains ranging from 3.5 to M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT 5 6.0 mm. These studies confirm that placing a material to maintain space will result in bone gain.…”
