The present study was conducted to evaluate clinically the initial stability of implants placed in dynablast putty DBM allograft using osstell based on the concept of resonance frequency analysis. The study involved twelve extraction sockets of 1st and/or 2nd mandibular molar teeth. The patients were chosen from the outpatient clinic in the oral and maxillofacial surgery department, faculty of oral and dental medicine, Cairo university and October 6th university based on the inclusion exclusion criteria previously mentioned. The need for extraction was confirmed by clinical and radiographic examination. Therefore, patients were grouped as follows: Group A (2 months group): comprised six extraction sockets left after graft was placed to heal, so the implant can be inserted after 2 months. Group B (6 months group): comprised six extraction sockets filled with graft as a method of alveolar ridge preservation and then implant is to be inserted after 6 months. Teeth were atraumatically extracted using a periotome and lower molar forceps, hand piece in some cases. The dynablast was packed to fill the socket to the level of the crestal bone; the socket was then sutured with figure of eight sutures using 3 / 0 black silk. Pressure pack was applied to the wound
