简要总结
This case series trial aims to evaluate the effect of a modified pedicle subepithelial connective tissue graft in creating anatomical papilla around one-stage delayed implant in the esthetic zone to establish better esthetics.
详细描述
- Preparation of the implant site will be prepared by a crestal incision on the ridge bisecting the existing keratinized mucosa and vertical releasing incisions extending to the vestibule. The papillae of the adjacent teeth are not included in the flap design.
- A full thickness flap will be raised buccally exposing the underlined ridge of the implant site. A surgical drill guide will be used for the precise placement of the pilot drill. After pilot drill application, the osteotomy will be prepared with the corresponding size of parallel drill.
- The implant will be placed in the recipient site by means of an insertion device. The implant neck will be positioned flushing with the crestal bone level.
- The healing abutment extension of the implant will be placed in such a way that the head of the implant protruded about 2 to 3 mm from the bone crest.
- Reassessment of the case to assure absence of any signs of inflammation and presence of normal tissues before the surgical procedure
