The placement of implants into extraction socket was introduced in the late 1970s. This approach has been reviewed extensively during the late decades, and seems promising. Several recent papers have presented clear clinical guidelines for patient selection and/or for an optical outcome. The majority of studies reported survival rates above 95%. There are some studies, however, reported detailed results about the esthetic outcomes. Recession of the facial mucosal margin was a common observation in several studies with immediate implants. It should be noted, however, that these studies did not select patients for immediate implant placement with inclusion criteria based on the hard and soft tissue characteristics associated with the extracted teeth. Today we knew, immediate implant placement is considered a complex procedure and should only be performed by experienced master clinicians. For studies of immediate implants, different combinations of surgical protocols (flap vs flapless surgery), grafting (bone and/or connective tissue grafts) and loading protocols (immediate loading vs early/conventional) were identified, which made it hard to draw a clear guideline procedure. The primary objective of implant therapy in the esthetic zone is an optimal esthetic treatment outcome with high predictability and a low risk of complication. Then result must be viewed from a mid- to long-term perspective. This review indicating some highlights of this technique and reveal the evidence for questions like: What are the objective criteria for immediate implant placement? Flapless or flap procedure, when why, where? The effect of placing a bone graft in the gap at immediately placed implants.do we need or we do not? Hard and soft tissue alterations in esthetic post extraction sites and immediate implant placement. Bone modelling at fresh extraction sockets immediate implant placement and how does the timing of implant placement to extraction affect outcome? Today what is the long-term result of immediate implant placement in esthetic zone? [ABSTRACT FROM AUTHOR] |
