With a strip autograft and xenogeneic collagen matrix (XCM) technique combination, autograft harvest requirements and patient morbidity are reduced. In this histologic evaluation, 12 strip autograft/XCM biopsy samples were compared with 3 reference samples of palatal strip autografts. Tissue morphology, keratin, and collagen expression appear identical, indicating that the combined grafting technique provides desired and physiologically normal keratinized gingiva.
