Free Soft Tissue Grafts FSTG) Using Autograft Palatal Donor Tissue vs. Xenograft Collagen Matrix (Zderm™)

Brief Summary

Participant in this study are asked to participate because they have teeth or dental implants that were identified as having very little gum tissue and would benefit from gum tissue graft surgery. This study has 2 groups that differ only in the material that will be used at the graft site: * Gum tissue taken from the patient's own palate (standard of care group) * Commercially available collagen matrix derived from porcine (pig) Achilles tendon (FDA-approved for the surgery done in this study). Both materials have been in use in dental practices for many years, but no studies have directly compared the outcomes between palatal tissue and the porcine collagen matrix we will use in this study. Participants will be randomized into one of the 2 groups using sealed envelopes (the process is like flipping a coin). All the study visits will take place during regular dental appointments that would be scheduled even if not participating in this research.
