Abstract

Objective: This study was performed to evaluate the primary stability of dental implants placed in closed sinus-lifting using osseodensification technique.
Subjects and methods: Ten patients with missing upper posterior teeth and inadequate bone height at least 5 mm under the floor of the maxillary sinus included in this research., secondary to sinus pneumatization, where there is not enough bone for placement of standard-length implant placed. The average age was (40:70) years old. Stability, bone height and bone density were evaluated during 9 months postoperatively.
Results: The findings of this study demonstrated that; the mean values of primary stability ISQ were 71.00±9.64. After 3 months the dental implant was exposed to assess stability, The device used was Ostell® ISQ (Ostell® ISQ, Gothenburg, Sweden), The mean values of ISQ were 72.70±7.59. According to implant stability, the stability mean values after 9 months were 76.70 6.20, which was statistically different from primary stability (p-value 0.029).
Conclusion: The osseodensification (OD) technique using Densah® Burs has the potential to greatly reduce the amount of time needed to place dental implant at the posterior maxilla while reducing trauma and postoperative discomforts.
