N2  - Purpose: The aim of the present study was to evaluate bone height gain following transcrestal sinus floor elevation using specially designed drills versus the conventional osteotome technique. Subjects and methods: Twenty two patients with one missing upper posterior tooth with  5-8 mm residual bone height beneath the maxillary sinus were randomly allocated into two groups; transcrestal sinus floor elevation with drills (test group) and transcrestal sinus floor elevation using osteotome (control group). Bone height gain was assessed 6 months postoperatively using CBCT as well as membrane perforation. Results: No statistically significant difference regarding the bone height gain after 6 months between the test (1.52 mm) and control (1.74 mm) groups was found. Only one case of membrane perforation occurred in each group representing a percentage of 9 %. Conclusion: Transcrestal sinus floor elevation is a successful technique regardless of the tools used with statistically significant difference between the initial bone height and bone height after 6 months
