Soft tissue dehiscence coverage around dental implants following an acellular dermal matrix allograft: a case report.

Acellular dermal matrix allograft (ADMA) is an alternative to a free gingival graft for keratinized tissue augmentation and root coverage. Soft tissue dehiscence is one of the major complications that can occur after replacing a missing tooth with a dental implant; it can lead to esthetic problems and have a negative impact on the long-term success of the implant. Soft tissue dehiscence coverage is not as predictable around dental implants as it is on root surfaces. This article describes a case involving soft tissue dehiscence, in which an ADMA was used to increase the width of keratinized mucosa around an implant-supported prosthesis, resulting in complete implant surface coverage due to the phenomenon of creeping attachment.
