Conventional treatment protocols in implant therapy follow a process of healing for 3 months, after tooth extraction, prior to implant placement, and a second healing phase of 3 to 6 months, after implant placement, prior to placement of an implant restoration. This conventional approach was first developed as it was thought that any forces placed onto the implant prior to bone healing would be detrimental to the osseointegration process. Immediate implant placement and immediate loading options have considerably shortened the overall treatment times and inconvenience to patients compared with conventional implant placement and loading protocols.1,2 

Few studies on immediate placement and loading of implants in the premolar area have been published and have demonstrated adequate short-term outcomes with survival rates ranging between 82.4% and 100%.3–7  A randomized controlled trial on immediately placed and restored maxillary anterior implants concluded that there were no significant...
