Using tissue graft substitutes in root coverage procedures can avoid complications associated with harvesting an autogenous tissue graft. However, the resulting coverage rate and volume stability are generally lower when using tissue graft substitutes as compared to autogenous tissue grafts. A new volume-stable porcine collagen matrix has recently been introduced for soft tissue thickening around dental implants; however, use of this matrix in recession coverage has not been reported. This case series demonstrates a novel surgical technique and reports clinical outcomes (7 to 12 months) of a minimally invasive root coverage procedure that uses vestibular incision subperiosteal tunnel access in combination with a volume-stable collagen matrix (VISTA-X).
