Objective: The aim of this study is to clinically evaluate the stability of short implants (5.5mm) versus standard implant (10mm) placed with osteotome sinus floor elevation in patients with edentulous posterior maxilla. Materials and Methods: The purpose of this study is to clinically evaluate the stability of short implants (5.5mm) versus standard implants (10mm) placed with osteotome sinus floor elevation technique in medically free patients. This study included 16 implants placed in 16 patients. With 8 implants in every group. Results: Pain and swelling were measured 12 and 8 days respectively after dental implant placement. Recession, probing depth, bleeding and plaque indices were recorded 4 months and 12 months after the day of implant placement. Conclusion: After analysis of the data of this present study, we can conclude the following: The two implant placement protocols showed comparable implant stability quotient (ISQ) and implant success. In terms of crestal bone loss, no statistically significant difference was found between both groups initially, 6 and 12 month followup. Except after 4 months, a significantly higher mean crestal bone loss was recorded in long implants with sinus lift Higher results of post-operative pain and swelling (12 and 8 days respectively) were evident in the control group (standard implant with osteotome sinus floor elevation) than the intervention group (short implant 5.5mm). but found to be statistically insignificant PPD, and MPI showed no statistically significant difference between both groups. MBI showed a significant higher values in long implants after 4 months (p=0.006) than short implants
