Ultra‐sonic bone surgery (USBS) has been recently introduced as a novel osteotomic technique. This clinical study reports on the application of this new technique to perform ridge‐split procedures. Over a period of 3.5 years, 57 patients underwent a split‐crest procedure with the aim to place 230 implants, 78 in the mandible and 152 in the maxilla, in order to rehabilitate nine full arches, three hemi‐arcades, 43 partial bridges and 24 single crowns. The initial ridge width varied between 1.5 and 5 mm, average was 3.2 mm. The final width of the ridge ranged from 4 to 9 mm, average was 6 mm. The split length varied between 4.5 and 40 mm, average was 15 mm. Inserted implants were 3.25–5 mm in diameter however most of them (82.4%) were standard implants of 3.75 mm; implant length was classically 10–13 mm. Two hundred and twenty‐eight (99.1%) out of the 230 planned implants were placed, the two non‐suitable sites were in the maxilla. In the mandible, the ridge augmentation procedure was drastically eased by performing a basal longitudinal discharge notch. At second stage surgery, eight implants failed to osseointegrate; the success rate for the placed implants was 96.5%. All implants have been loaded for at least 2 months and no implant was lost after loading. One hundred and eighty‐one and 77 implants have been loaded for at least 6 and 12 months, respectively. The 3‐year life‐table analysis of loaded implants showed a cumulative survival rate of 100%. The split‐crest procedure performed with USBS showed to be safe and comfortable.
