Grafted versus non grafted ultrasonic ridge splitting technique with simultaneous implants placement into narrow posterior mandibular alveolar ridge: a clinical and radiographic study

Abstract

The present study was designed to compare clinically and radiographically between the traditional methods and the ultrasound in ridge splitting technique (RST) with simultaneous implant placement into narrow posterior mandibular alveolar ridge. This study was carried out on 20 patients with partial edentulous narrow posterior mandibular alveolar ridge. Patients were divided randomly into two equal groups (group I was treated with RST with osteotome and simultaneous implant placement into their ridges associated with bone graft as a gap filler after splitting; group II was treated with RST by the ultrasound and simultaneous implant placement into their ridges associated with bone graft as a gap filler after splitting). Patients were evaluated clinically to assess probing depth and implant stability quotient, and radiographically to assess the alveolar ridge width and the marginal bone level measurement parameters at 3, 6, 9, and 12 months. The results of the present study showed no significant difference of postpartum depression and significant difference in implant stability quotient between the two groups at the second interval, and there was a superiority of the group ll in marginal bone level between the two groups at the different intervals with statistically significant difference, especially at the end of the observation.
