NCT04029324

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.

Study Arms (2)

Immediate implant placement

ACTIVE COMPARATOR

Implants are placed immediately after extraction

Procedure: tooth extractionProcedure: Implant placementProcedure: Bone augmentation

Early implant placement

PLACEBO COMPARATOR

Implants are placed 4-8 weeks after extraction

Procedure: tooth extractionProcedure: Implant placementProcedure: Bone augmentationProcedure: Coronally repositioned flap

Interventions

Under local anesthesia, tooth will be extracted atraumatically.

Early implant placementImmediate implant placement

Dental implants will be placed according to the instructions in fresh sockets or alveolar ridge.

Early implant placementImmediate implant placement

Bone substitute will be used to augment or maintain the bone contour.

Early implant placementImmediate implant placement

After periosteal releasing incision, mucoperiosteal flap will be sutured at a more coronally position

Early implant placement
