The aim of this study was to evaluate the use of a new collagen matrix (Mucograft®; Geistlich Pharma AG, Wol- husen, Switzerland) in the soft tissue reconstruction after excisional biopsy. The healing of soft tissues after bioptical excision tends to heal by secondary intention. To avoid this, the soft tissue grafts can be harvested from the palate, retromolar pad, or (if available) edentulous site. Disadvantages of harvesting the graft from the retromolar pad and edentulous site are minimal amount of tissue availability and thinner grafts are obtained. The use of collagen matrix is also reported in literature and could represent an optimal solution in the future. Mucograft® is a pure collagen type I and III matrix of porcine origin without further cross-linking. Mucograft® consists of pure porcine collagen obtained by standardized, controlled manufacturing processes. The product made up of porcine collagen has a bilayer structure. The compact layer consists of compact collagen fibers which has cell occlusive properties and allows tis- sue adherence as a prerequisite for favourable wound healing. This layer protects against bacterial infiltration in open healing situations and has appropriate elastic properties to accommodate suturing. A second layer consists of a thick, porous collagen spongious structure. In this paper, we report about a case of surgical site healing after biopti- cal excision proliferative verrucous leukoplakia of the hard palate.
