Brief summary
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.
Interventions
PROCEDUREConnective tissue graft
Connective tissue graft (CTG) is an oral and maxillofacial surgical procedure first described by Alan Edel in 1974. It includes the preparation the recipient site of tissue exhibiting recession by incising the gingival, obtaining the CTG from the donor site, securing the CTG at the recipient site and suturing the incised gingival tissue at both the donor and recipient sites.
PROCEDUREsocket shield technique
The procedure is used to split the teeth and preserve the buccal part
PROCEDUREImmediate implant placement
The implant will be placed in the frest socket immediately after tooth extraction
