Short-length (6 and 8 mm), wide-diameter (4.8 mm) implants were placed into the lateral part of the maxilla in 28 patients, as they had insufficient bone height. The 6-and 8-mm length implants were placed into the sights where the average bone heights were 6.3 and 9.9 mm, respectively.
Although a 6-mm implant was lost in early phase,remainder 47 implants were undergoing maintenance in the 22 month of an average follow-up time.
