case_images: (a) Soft tissue fenestration of 3 x 3 mm at the labial site of the maxillary left canine implant, 2 mm apical to the mucosal margin. (b) CBCT radiographs showing apical labial bony dehiscence and vertical bone loss of 5.56 mm in depth at the mesial and distal surfaces of the implant. (c) The implant presented soft tissue dehiscence of 4 x 4 mm exposing the fixture at 2 weeks after initial debridement.

case_images: Mucosal fenestration of 3 x 3 mm was noted at the labial implant site, 2 mm apical to the mucosal margin (Figure 1(a)). The labial soft tissue of the implant disappeared and presented as 4 x 4 mm soft tissue dehiscence (Figure 1(c)).
case_images: (a) Recipient site with partial thickness flap creating an envelope. (b) Donor site for harvesting the soft tissue graft of 16 x 8 mm. (c) Graft placement.

case_images: The recipient site was prepared by creating a partial thickness envelope flap at the labial aspect of the implant and extended 6-7 mm mesially, distally, and apically (Figure 2(a)). The graft was de-epithelialized, except for the area that lay over the exposed implant fixture (Figure 2(b)).
case_images: (a) Clinical appearance at the follow-up periods after surgery. (b) CBCT radiographs at 2 years after surgery demonstrating the remaining intrabony defect depth 3.75 mm at the mesial and 4.95 mm at the distal surfaces of the implant. The width of the intrabony defect was narrower than the pretreatment.

case_images: The soft tissue around the graft was slightly inflamed and edematous (Figure 3). The mucosal margin covered the implant neck which indicated some creeping after the connective tissue grafting (Figure 3). CBCT radiographs demonstrated the improvement of the intrabony defect in depth (3.75 mm at mesial and 4.95 mm at distal) and width when compared to the pretreatment (Figure 3).
