Ridge expansion with acellular dermal matrix and deproteinized bovine bone: a case report.

Reduction of the original height and width of the alveolar bone of an edentulous site precludes optimal positioning of implant fixtures and may esthetically compromise the prosthesis. Ridge expansion at the time of extraction can prevent the need for ridge reduction and reduces the number of surgical interventions.A patient with a narrow ridge with buccal deformity was treated for the staged placement of an implant. The tooth was extracted. The socket was expanded with an osteotome and an acellular dermal matrix graft was applied as a barrier membrane. The underlying bone showed good healing with maturity and the acellular dermal matrix had the potential to increase the keratinized tissue in the extraction area.
