Report of 1633 implants in 814 augmented sinus areas in function for up to 180 months.

Purpose: The long-term success of implants functioning in sinuses augmented with a variety of materials were evaluated in 2 private practices.

Materials: Treatment outcomes of 1814 augmented sinuses, and subsequent placement of 1633 implants into 763 augmented sinuses, were assessed through clinical and radiographic examinations in 2 private practices. Statistical analysis was carried out utilizing the analysis of variance method and step-wise linear regression at P < 0.001.

Results: Eight hundred fourteen sinus augmentation procedures were performed. Eight hundred six sinus augmentation procedures were deemed successful (99.0%), as defined by implants functioning successfully in the augmented sinus areas. A variety of augmentation materials were utilized to effect sinus augmentation. Of the 1633 implants placed in augmented sinuses, 1613 were functioning successfully, yielding an accumulate success rate and function of 98.1%. The mean implant time in function was 69.1 months. The longest functioning implants had been in function for 180 months.

Discussion: The results, from 2 private offices in conjunction with numerous restorative clinicians, utilizing a variety of augmentation materials and implants, were comparable to those reported by other authors. The clinical predictability of sinus augmentation therapy and of implants functioning in augmented sinuses were reinforced.

Conclusion: Predictable sinus augmentation therapy may be obtained through the use of a variety of regenerative materials. Titanium implants of various configurations and surface topographies will function successfully in augmented sinuses over time.
