Intervention / Behandling |
|---|---|
|
Experimentell: dental implant with application of free gingival graft
Group I: will include 10 patients in which participants will receive dental implant with application of free gingival graft which will be taken from the hard palate to increase the width of keratinize gingiva
|
Group I: All patients will be operated under local anaesthesia;. .. Two vertical releasing incisions delineated the partial thickness flap. The flap will be apically positioned and sutured. A gingival graft will be taken from the hard palate. The graft will be 1 to 2 mm in thickness and its size will be determined depending on recipient size and free from adipose tissue. The graft will be trimmed to adapt to the shape and size of the recipient site then suturing the graft to the recipient sites by using 4-0 vicryl suture. Group II: All patients will be operated under the same local anaesthetic as in group I. Crestal incision will be performed and full thickness mucoperiosteal flap will be reflected just to access the site. Two vertical releasing incisions delineated the partial thickness flap. The flap will be apically positioned and sutured. Porcine collagen matrix will be placed in the recipient site and sutured by using 4-0 vicryl suture. |
