The purpose of the message was the comparison of change in the width and quality of keratinized tissue created in the lower vestibuloplasty area. Preliminary results of the case-control study involving 71 patients showed that autotransplantation managed to create the necessary buffer zone with the desired thickness of the mucosa and is particularly justified in cases of «washing board effect». However, the method is technically complicated and more expensive and painfull for patients. The use of alternative materials of artificial origin, such as «Mucograft» and bloodstatic and desinfecting sponge simplifies the procedure technique thereby reducing operational risk but often does not lead to the formation of a fully keratinized gingiva.
