Longitudinal Ridge Split Osteotomy and Simultaneous Implant Placement

Longitudinal ridge split osteotomy was performed in 33 cases with horizontal alveolar bone deficit, with a sufficient apical basis, that provides primary stability of the implants. The survival rate of the implants was 87, 9 %. The mean marginal bone loss is 1.586mm. Bleeding on probing is registered in 45, 5 % of the cases. There was found no correlation between the marginal bone loss and the bleeding on probing. The complication rate was 33, 4 %. In 18, 2 % of the cases was registered fracture of the vestibular bone plate.
