Summary

The purpose of this study is to prospectively evaluate whether including an allogeneic gum graft (PerioDerm*) during dental implant therapy improves implant health and appearance. On the day of implant surgery, participating subjects will be randomized to either receive or not receive a supplemental gum graft along with the implant. Participating subjects will also be asked to complete a brief (about 15 questions) oral health questionnaire. Participating subjects will return to the clinic about 8 weeks post surgery for digital crown impressions and again at 11-13 weeks after surgery for crown placement. Participating subjects will also return to clinic at 1 year after implant placement for implant evaluation. At this final study appointment, x-rays and a 3D intraoral scan will be obtained for the purpose of measuring alveolar volume. The health of the mucosa surrounding the implant and subject satisfaction will be assessed via bleeding upon probing and completion of a brief questionnaire, respectively.
