Brief Summary

The overall objective of this project is to evaluate, over a period of 1 year, the outcomes of either conventional free gingival graft (FGG) or mesh-FGG to increase the width of keratinized mucosa (KM) at implant sites.

Outcome Measures

Primary Outcomes (1)

  • Changes of Keratinized Mucosa width (KMW)

    Measured as the distance from the muco-gingival-junction to the occlusal portion of the mucosa

    up to 1 year

Secondary Outcomes (3)

  • Changes of Keratinized Mucosa Thickness (KMT)

    up to 1 year

  • Patient Morbidity

    up to 2 weeks

  • Patient Satisfaction

    up to 1 year

Study Arms (2)

Free Gingival Graft

ACTIVE COMPARATOR

A mucogingival surgery where a conventional free gingival graft harvested from the palate is placed on a recipient site prepared to increase the width of KM at implant sites.

Procedure: Conventional Free Gingival Graft

Meshed Free Gingival Graft

EXPERIMENTAL

A mucogingival surgery where a meshed free gingival graft harvested from the palate is placed on a recipient site prepared to increase the width of KM at implant sites.

Procedure: 'Mesh Free Gingival Graft

Interventions

Implant site with insufficient dimensions of KM will be covered by a conventional free gingival graft.

Free Gingival Graft

Implant site with insufficient dimensions of KM will be covered by a expanded meshed free gingival graft.
