Abstract
The aim of the study is to clinically and radiographically evaluate the primary stability of short (5.5mm) implants versus standard length (10mm) implants placed with osteotome sinus floor elevation. The present study consisted of a total of 12 patients (8 females and 4males, aged 30-60years) with a maxillary posterior edentulous area whom were recruited from the outpatient clinic of the Periodontology department, faculty of oral and dental medicine, Cairo University between 2016 and 2017. The patients were randomly assigned to one of two groups on the day of the surgery: group A: Short implants (5.5 mm in length). group B: Standard length implants (10 mm in length placed with osteotome sinus lift technique).
Clinical parameters including implant stability, Post-operative pain and swelling, crestal bone loss, probing depth, gingival recession, modified plaque and bleeding index were measured
