Özet: Alveolar ridge splitting technique with immediate implant placement is usually performed to overcome the deficiency of the alveolar bone width and significantly shortens the treatment time. In the mandible there is a higher risk of malfractures and a lack of initial stability for the implants, so the two-stage technique is recommended. The present study reports the clinical results of the two-stage ridge technique in the posterior region of the mandible. A total of 12 patients with an edentulous narrow alveolar bone ridge in the posterior mandibular region were included in the present study, Two-stage ridge splitting technique was applied to increase the width of alveolar bone. After 4 months of surgery, 15 dental implants were inserted in the expanded ridges. The alveolar bone width, complications of the surgery, and survival rate of dental implants were evaluated. The mean bone gain in the width of the alveolar bone was: after surgery 2.8 mm (SD: 0.53) (range, 2.1 – 3.6 mm), and after 4 months of surgery 2.22 mm (SD: 0.23) (range, 1.9 – 2.6 mm). One case of wound dehiscence was recorded. The survival rate of implants was 93.3 % after 6 months of functional loading. 84.61% of the expanded areas were successful in providing an adequate width. This technique can be considered a safe procedure with satisfactory results if appropriate cases selected.
