Immediate implant placement (IIP) has been an attractive treatment concept for both patients and clinicians due to reduced surgical interventions and total treatment span. Although soft-tissue alterations or midfacial recession have been demonstrated in previous studies, recent studies have reported positive result following IIP with the modification of surgical interventions. However, high-quality evidence (≥Ib: evidence from at least one randomized controlled trial) on comparing the clinical outcome of IIP with early implant placement (type 2) is limited.
