Fifteen consecutive patients aged from 18 to 60 years, considered eligible after clinical and radiographic evaluation, were allocated in 2 groups (flapped and flapless) that underwent delayed implant placement protocol with SLActive and measurement of stability (ISQ) by the Ossetll device. Marginal bone loss (MBL) was estimated by cone beam computed tomography (CBCT) during three different periods of time. The mean values of implant stability and marginal bone level significantly decreased after 8 weeks, while ISQ and MBL significantly increased or remained unchanged after 24 weeks, compared with baseline data. Apart from one patient, who suffered from transient numbness following surgery, spontaneously and completely resolved 3 weeks later, no serious complications were reported throughout the study. These results demonstrated that ISQ and MBL were affected by many factors (age of the patient, bone density at the recipient site and functional implant zone where the traumatic and ischemic zones were highly affected during the 2nd and 3rd follow-up appointments, respectively).
