title: Unexpected soft tissue changes in response to root coverage using an acellular dermal matrix allograft: 12–year follow up.
abstract: A woman undergoing orthodontic treatment presented with recession and reduced keratinized gingiva on teeth 31 and 41. The patient declined creation of a donor site for conventional autogenous connective soft tissue grafting and opted for an acellular dermal matrix soft tissue substitute for root coverage. Orthodontic treatment followed, and the patient returned for orthognatic surgery after 12 years. Long-term follow up revealed that root coverage remained stable over time and creeping attachment on both teeth was observed. Unexpectedly, an increase in the width of keratinized gingiva was observed. No adverse effects of orthodontic treatment carried out after grafting were observed.
