About

The present study aims to evaluate the clinical outcomes of immediate implant placement with connective tissue graft or socket shield. Previous studies have demonstrate the intact buccal bone plate plays an important role in the stability of peri-implant soft tissue around immediately placed implants. However, it remains controverisal whether soft tissue stability could be achieved in immediate implant placement with connective tissue graft or socket shield.

Enrollment: 40 estimated patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Patients in need of single implant treatment in anterior maxilla Patients with small dehiscence in the buccal bone plate （<2mm vertical bone loss and <5mm horizontal bone loss） Patients with natural teeth adjacent to implant site

Trial design

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: None (Open label)

---

40 participants in 2 patient groups, including a placebo group

Control Group

Placebo Comparator group

Description:

Patients in the control group will follow the conventional treatment protocol combined with connective tissue graft. Briefly, hopeless tooth will be extracted atraumatically. Implant will be placed in the palatal side and grafting materials will be filled in the buccal gap. Then, connective tissue graft will be harvest from palatal and fixed between bucall mocosa and bucall bone. Healing abutment will placed and collegan sponge will be used to seal the wound. After 4 months, implant impression and crown delivery will be finished.

Treatment:

Procedure: Immediate implant placement

Procedure: Connective tissue graft

Test Group

Experimental group

Description:

Patients in the test group will receive conventional immediate implant placement combined with socket shield technique. Briefly, the hopeless teeth will be splited from mesial and distal, the buccal part will be preseved and the palatal part will extracted. Implant will be placed in the palatal side and grafting materials will be filled in the buccal gap. After 4 months, implant impression and crown delivery will be finished.

Treatment:

Procedure: socket shield technique

Procedure: Immediate implant placement
