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.CBCT examination was made for all patients according to the following schedule:1.Pre-operative.2.Immediate post-operative grafting for both groups. 3.Two months post-operative, for group A. 4.Six months post-operative, for group A and B. The collected results were tabulated and statistically analyzed. The study results showed that there was statistically significant higher ISQ reading for group B than that of group A meaning a higher initial implant stability for group B than that of group A.Conclusion:From the results of the present study, the following can be concluded that socket grafting after extraction is recommended to preserve alveolar bone volume for future implant placement. Dynablast showed good handling properties, (increased bone volume and density as proved by radiographic results. Therefore we recommend this material for alveolar ridge preservation). OsstellTM ISQ is a reliable device for assessing implant stability as a non-invasive technique. While taking readings with OsstellTM ISQ no significant difference between the mesio-distal and bucco-lingual readings but for accurate assessment of the implant stability it should be followed up to see the change in the ISQ readings which relates to the implant stability. Further studies will be needed over a larger sample size. Follow up should be considered in future studies to evaluate the increase or decrease of the ISQ readings.
