Maxillary sinus augmentation using deproteinized bovine bone (Bio-Oss) and Impladent Dental Implant System. Part I. Comparison between one-stage and two-stage procedure.
This study was undertaken to compare implant survival after one- or two-stage sinus augmentation. Ninety-two maxillary sinuses in 77 patients were augmented with deproteinized bovine bone (Bio-Oss). These sinuses were sub-divided into two groups: Group 1 (n = 49) was operated on with a one-stage procedure, and Group 2 (n = 43) with a two-stage operation. A hundred and eighty-five implants were inserted in these augmented sinuses. Clinical and radiographical evaluations were performed and recorded according to certain criteria. The follow-up period was ranging from 16 to 44 months. Out of the implants inserted using the one-stage procedure, all survived. Two implants failed in the two-stage procedure group (98.91% implant survival). This study showed that no statistically significance was observed between the two surgical techniques (P < 0.05). Therefore, the authors concluded the type of surgical procedure (one- or two-stage) has no effect on implant survival.
