Abstract: Objective To observe the histological effect of acellular dermal matrix(ADM)on insufficiency in guide keratinized tissue regeneration. Methods 6 cases of single anterior tooth implantation in the hospital in 2016 were included in the study. 3 cases were treated with immediate tooth extraction and implantation. Bone substitution materials were grafted in the space between the tooth extraction socket and the implants. The keratin-ized tissue dehiscence was covered by double layers of acellular dermal matrix membrane(Heal-All?,ZH-BIO, China),which was fixed to the adjacent soft tissue by suturing. Another 3 cases were routinely treated with delayed implantation of single anterior tooth. All the cases were subject to harvesting of the cover soft tissues of implants with a punch 4 months later. The new grown soft tissues were histologically observed. Results All cases were sur-vived. The new grown keratinized tissues were observed. Conclusion Acellular dermal matrix can guide the aug-mentation of keratinized tissues.
