In the maxillary posterior region, not only the quality of the bone is lesser, but also the volume of the bone tends to be insufficient. For this reason, sufficient intraosseous length of the fixtures is seldom secured. When the preoperative bone height is less than 10 mm, stability of implant cannot be established by the existing bone alone; socket lift, however, enables implant placement into the prosthetically ideal position. Amongst various sinus floor elevation procedures, lateral window technique and socket lift are considered as the standard methods and less invasive socket lift has been reevaluated. The present paper is to report on the clinical assessment of maxillary posterior implant treatment in combination with socket lift, covering 181 implants placed between 1992 and 2011, in 150 patients, who received the socket lift treatment at 4 clinics, members of Kyoto Institute of Implantology. The result of the survey, demonstrating applicability of socket lift to various prosthetic options and a high 10-year survival rate of implant (96.7％), suggested its clinical effectiveness.
