Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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 Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Immediate implant placement

Implants are placed immediately after extraction

Group Type ACTIVE_COMPARATOR

tooth extraction

Intervention Type PROCEDURE

Under local anesthesia, tooth will be extracted atraumatically.

Implant placement

Intervention Type PROCEDURE

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

Bone augmentation

Intervention Type PROCEDURE

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

Early implant placement

Implants are placed 4-8 weeks after extraction

Group Type PLACEBO_COMPARATOR

tooth extraction

Intervention Type PROCEDURE

Under local anesthesia, tooth will be extracted atraumatically.

Implant placement

Intervention Type PROCEDURE

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

Bone augmentation

Intervention Type PROCEDURE

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

Coronally repositioned flap

Intervention Type PROCEDURE

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