Peñarrocha Oltra D, Agustín Panadero R, Bagán L, Giménez B, Peñarrocha MA. Indirect osteotome maxillary sinus floor elevation: an update. J Oral Implantol. 2012 Dec;38(6):799-804.
The objective was to review publications on indirect osteotome maxillary sinus floor elevation (OMSFE) procedures. Studies published between 1999 and 2010 on patients with a minimum of 1 year of follow-up were analyzed. Fourteen studies were included. Indirect OMSFE is indicated for a bone height of 6-8 mm. More bone height was gained when graft material was used. Schneiderian membrane perforation was the most frequent complication. Survival rates varied between 93.5% and 100%. Osteotome sinus membrane elevation is a predictable and effective procedure for placing implants in areas of the posterior maxilla with low bone height.
