OLATE, Sergio et al. Restrospective Research in 91 Maxilary Sinus Floor Elevation Surgery for Implant Rehabilitation. Int. J. Odontostomat. [online]. 2012, vol.6, n.1, pp.81-88. ISSN 0718-381X.

Osseous graft for sinus floor elevation has been used for a long time with good results. The aim of this research was to evaluate the operatory and post operatory characteristic of 91 consecutively surgeries for sinus floor elevation. We selected medical records of 72 patient between 18 and 66 years of age for the treatment with local or general anesthesia. Data analysis was realized with a Fisher test with p<0,05 for statistical significance. In the 74.7% autogenous bone with or without biomaterial was used; in 86,8% intraoral donor site was used. We installed 101 implants with 69.3% installed in the second surgical time and the other 31 implant installed in the same surgical time with the bone graft; we did not observe any statistical relation in the survival of implants installed in surgical times one or two (p>0,05). We observed the loss of 4 implants without relation with the material used for sinus lift (p>0,05). The more common complication was membrane laceration in 18.7%, and in 13 of 17 cases with this situation the same surgery was performed at a later time. Finally, it can be concluded that the sinus lift is a recognized and safe procedure showing implant stability for adequate osseointegration.
