Regenerative strategies for anterior esthetic rehabilitation: a clinical and histologic case report

In order to solve the substantial challenge of achieving natural esthetics in compromised situations, a number of techniques and materials have been developed to restore deficient alveolar bone and maintain existing bone and soft tissue. This article reviews developments in both areas and reports on a clinical treatment in which a new form of xenograft in conjunction with a cross-linked, cell-occlusive membrane was used in a severely compromised anterior maxilla in preparation for placement of platform-switched implants.
