Purpose: Inserting Implants in the posterior of maxilla is a big challenge for dental Implantologist, especially if there is no enough crestal bone height. Press-fit implants are well known and have a good secondary stability with no primary stability.   This in vivo study aims to evaluate a new technique in inserting simultaneous those non primary stable press-fit implants with internal sinus lift for poor crestal bone height in posterior maxilla.

Material and methods: 12 Press-fit implants were inserted in the posterior maxilla for 8 patients by immediate sinus floor elevation with synthetic bone grafts. All implants obtained the primary stability with stabilizers of titanium mesh membranes and mini screws. Patients got over implants prosthesis after 3-6 months. Results: 11 implants of 12 have been well Osseointegrated. Patients were satisfied by using this technique. As to success rate it was 91.6%. Conclusion: This study showed that internal sinus lifting in poor residual bone height is Not a contra indication for Simultaneous Implants with Internal Sinus Lifting
