Brief Summary

This study aims to compare the changes in the peri-implant mucosa during the application of two soft tissue grafting methods, which are free gingival graft (FGG) and connective tissue graft (CTG) taken from the palatine in terms of the width of the keratinized mucosa and the thickness of the peri-implant soft tissues.

Outcome Measures

Primary Outcomes (2)

  • The width of the keratinized gingiva

    The width of the keratinized gingiva will be measured using a UNC-15 probe from the middle of the alveolar process at the site studied to the mucogingival junction, which was determined by the rollover technique.

    after 1 month and 3 months

  • The thickness of the peri-implant soft tissues

    The thickness of the peri-implant soft tissues will be measured clinically by the direct transgingival propping method.

    after 1 month and 3 months

Study Arms (3)

Free gingival graft

EXPERIMENTAL

Free gingival graft will be applied and and followed for 3 months

Other: Efficacy of free gingival grafts during in the increasing of peri-implant keratinized tissue width and soft tissues thickness

Connective tissue graft

EXPERIMENTAL

Connective tissue graft will be applied and and followed for 3 months

Other: Efficacy of connective tissue grafts during in the increasing of peri-implant keratinized tissue width and soft tissues thickness

No grafts will be applied.

OTHER

No grafts of any types will be applied.

Other: No types of grafts will be made to improve the quality of the peri-implant mucosa

Interventions

Two vertical incisions will be made in the previously elevated flap against the placed implant , where these two incisions will be 10 mm apart from each other, and the free graft to will be placed in this distance (10 x 10 mm). The graft will be obtained from the donor site (the hard palate), and will be thinned to obtain a regular graft with the required thickness. After that, the graft will be moved to its correct place accurately, while avoiding leaving a distance between the graft and the tissue underneath, and the graft will be sutured well to ensure its stability and correct placement.

Free gingival graft

Vertical incisions will not be made in the previously elevated flap against the placed implant, where there is no need to suture the flap apically of the grafting place because the graft will be covered with it after fixing it in place. The area will be washed with the serum to remove the clot before fixing the graft.The graft will be obtained from the donor site according to the previously mentioned method. Then the epithelium will be removed to leave the connective tissue underneath, and then the graft will be moved to its place (buccally dental implant site) and the flap will be sutured over it.

Connective tissue graft

The simple suturing of the two surgical incisions will be done after the completion of the dental implant process, with no procedure will be made to improve the quality of the peri-implant mucosa.

No grafts will be applied.
