Aim of the study The rationale for conducting the present study is to evaluate the efficacy of porcine collagen matrix in the management of defective width of keratinized mucosa around dental implant.
Therefore, the primary objective is to evaluate the integration of porcine collagen matrix with the recipient site and measuring the amount gained of keratinized mucosa. The secondary objective is to assess the pink esthetic score around dental implant following porcine collagen matrix compared to the free gingiva graft.

| All dental implants will be placed in edentulous the area with application of free gingival graft (Group I) or with incorporation of porcine collagen matrix (Group II). | Procedure | 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. |
