Clinical Outcomes of Immediate Implant Placement and Early Implant Placement

Shanghai Ninth People's Hospital Affiliated to Shanghai Jiao Tong University100 enrolled

Overview

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.
