Abstract
Dental implants portray a highly successful treatment approach. However, implants in the maxillary posterior region were associated with compromised bone quantity and quality. Moreover, the posterior teeth are subjected to higher occlusal forces than the anterior teeth. In order to overcome these shortcomings, an array of augmentation techniques have been traditionally employed to increase the residual ridge dimension including open and closed sinus lift. Such procedures have been reported to have several drawbacks including increased patient morbidity, costs and complications. A valid alternative for such cases, is the use of short implants. The aim of this study is to clinically evaluate the primary stability of short (5.5mm) implants versus standard length (10mm) implants placed with osteotome sinus floor elevation. This study included 16 implants placed in 12 different patients with a mean age of 37.5 and age range 25-50. 8 implants were placed in the control group and 8 implants in the intervention group. Primary stability and crestal bone loss were both assessed initially and then at 4, 6 and 12 months after implant placement. Pain and swelling scores were recorded for 12 and 8 days respectively starting at the day of implant placement. Recession, probing depth, bleeding and plaque indices were also recorded at 4 months and 12 months
