Abstract
Purpose: The aim of this study was to evaluate 1 year cumulative survival rate of implants placed on augmented sinus using Osteon®, bone graft material and to assess height of the grafted material radiographically. Material and
Methods: 10 maxillary sinuses were augmented in 10 patients and 25 implant fixtures were installed simultaneously or after 6 months healing period. The height of the sinus graft material was measured using panoramic images immediately after augmentation and up to 19 months subsequently. Changes in the height of the sinus graft material were calculated with respect to implant length and original sinus wall height.
Results: The cumulative survival rate was 100% in all 25 implants. Additionally, normal healing process without any complication was observed in all patients. The mean crown/Implant ratio was 1.25. The mean marginal bone loss was 0.95㎜ and the mean resorption rate of Osteon® was 0.05㎜/month. The fastest resorption site of Osteon® is the first molar area. The grafted material was well maintained in sinus and decreased slightly over 1 year.
Conclusion: In conclusion, It can be suggested that Osteon® may have predictable result when it was used as a grafting material for sinus floor augmentation.
