Keratinized Tissue Augmentation Using Augmented Gingival Matrix Compared to Free Gingival Graft Around Implants

This is a 12-month, randomized, examiner-blinded, controlled, two-arm, parallel-group, single-site clinical trial comparing a biocompatible tissue graft (Augmented Gingival Matrix barrier) with a free gingival graft (FGG) to increase the keratinized tissue around implants in medically healthy subjects. Subjects will be enrolled in a balanced manner (1:1; treatment:control) into one of the 2 following treatment arms for keratinized tissue augmentation: 1. Group A: Augmented Gingival Matrix barrier (Test group) 2. Group B: Free gingival graft (Control Group)

Inclusion Criteria: * • Willing and able to abide by the terms of the consent form and sign the Informed Consent form * Good general health as evidenced by medical history * Ages 18 and over * Edentulous or partially edentulous patients who had undergone dental implant surgery * Patients exhibiting KT/mucosa width of \>0.5 but \
