Indirect Osteotome Maxillary Sinus Floor Elevation: An Update
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.
