Several soft tissue graft materials have been utilized over the years as alternatives to the autogenous connective tissue graft for reducing patient morbidity. In particular, a novel volume-stable xenogeneic collagen matrix (VXCM) has recently been introduced for soft tissue augmentation at implant sites. The VXCM is porous in nature, and its mechanical properties suggest utilizing a specific flap approach when treating multiple adjacent gingival recessions (MAGRs). Herewith, a minimally invasive surgical technique is described in combination with VXCM for treatment of MAGRs. Five patients with 16 MAGRs were treated with this approach. All sites healed uneventfully, and patients reported minimal discomfort. At 6 months, the technique resulted in a mean root coverage of 94.73%, and complete root coverage was achieved in 13 sites (81.25%). The proposed minimally invasive approach may have potential to enhance flap blood supply and graft vascularization, promoting rapid healing with minimal postoperative discomfort. In addition, this approach can result in satisfactory clinical, esthetic, and patient-reported outcomes. Future adequately powered clinical trials are needed to validate the findings of this preliminary report.
