LITERATURE REVIEW Indirect Osteotome Maxillary Sinus Floor Elevation: An Update ´ Javier Romero-Millan, DDS Luis Martorell-Calatayud, DDS ˜ Maria Penarrocha, PhD, DDS* ´ Berta Garcıa-Mira, PhD, DDS 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. Key Words: indirect sinus elevation, osteotome technique, osteotome sinus floor elevation INTRODUCTION trophy of the alveolar crest and pneumatization of the maxillary sinus limits the quality and quantity of residual bone, therefore complicating the placement of implants in the posterior maxillary area.1,2 Various classifications have been established to determine the most appropriate treatment based on the pattern of alveolar resorption: Misch3 established 4 groups in function of the bone height existing between the free margin of the alveolar process and the floor of the maxillary sinus. In 2009, Chiapasco and Zaniboni4 established another classification according to the height and width of the alveolar ridge and the intermaxillary relationship of the patient. The need to increase bone volume has led to the development of maxillary sinus augmentation procedures,5 although other therapeutic options are available to resolve this anatomic limitation, such as the use of angulated, zygomatic, or pterygoid implants.6–9 Indirect osteotome maxillary sinus floor elevation (OMSFE) is generally employed when the Department of Oral Surgery, University of Valencia, Valencia, Spain. * Corresponding author, e-mail: maria.penarrocha@uv.es DOI: 10.1563/AAID-JOI-D-11-00160 A residual bone height is equal to or greater than 6 mm10; in cases with higher resorption, the direct sinus elevation technique is used.2,11,12 The indirect osteotome technique offers a number of advantages: the surgery is more conservative, sinus augmentation is localized, there is a low rate of postoperative morbidity, a shorter time to implant loading is possible than with the direct technique, and high survival rates of around 90% are obtained.5,13 The aim of this study was to review publications reporting on indirect OMSFE and to evaluate the influence of the graft material, the gain in bone height, and the amount of bone resorption. Likewise, the aim was to assess the complications of this surgical technique and the survival rates of implants placed in these areas. MATERIALS AND METHODS Inclusion criteria and search strategy Studies indexed in PubMed published between January 1999 and January 2010 on patients treated by OMSFE were analyzed. Only human clinical studies using the indirect osteotome technique with simultaneous placing of implants, a minimum of 10 patients, and at least 1 year of follow-up were included.
