Localized management of sinus floor (LMSF) achieves implant placement and sinus lifting simultaneously. LMSF is a further application of the principles of the edentulous ridge expansion (ERE) technique. It comprises the dissection of a partial-thickness flap, the buccal expansion of the residual alveolar bone, and the fracture and elevation of the sinus floor with simultaneous implant placement. Three hundred three patients were treated with 499 implants placed using the LMSF between April 1988 and December 1993. The selected patients, who showed no signs of sinus pathology, exhibited insufficient vertical alveolar bone dimensions for the placement of dental implants with the traditional technique. The minimal residual alveolar bone height was between 5 and 7 mm. Based on the criteria established by Albrektsson and his coworkers in 1986, the success rate of the 499 implants placed with the LMSF was 97.5%.
