Tooth Diseases, Tooth Fractures
Conditions
Brief summary
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.
Interventions
PROCEDUREtooth extraction
Under local anesthesia, tooth will be extracted atraumatically.
PROCEDUREImplant placement
Dental implants will be placed according to the instructions in fresh sockets or alveolar ridge.
PROCEDUREBone augmentation
Bone substitute will be used to augment or maintain the bone contour.
PROCEDURECoronally repositioned flap
After periosteal releasing incision, mucoperiosteal flap will be sutured at a more coronally position
