  • Title: [Less invasive sinus lift using the technique of Summers modified by Lazzara].
    Author: Defrancq J, Vanassche B.
    Journal: Rev Belge Med Dent (1984); 2001; 56(2):107-24. PubMed ID: 11508121.
    Abstract:
    The sinus floor elevation (sinus lift) is a procedure used for treating patients with very large pneumatisation of the maxillary sinus and thereby with severe atrophic maxilla (height of the residual alveolar bone between 5 and 8 mm). A modification of this technique is the osteotome sinus floor elevation: this is a less invasive method of creating sites with osteotomes by crestal approach in locations with insufficient bone for insertion of oral implants. With larger osteotomes, bone graft substitutes are placed through the osteotomy site to provide a sinus floor elevation and an augmentation of the crestal bone. Therefore, via the osteotome technique, longer oral implants can be inserted.
