Original articles describe the digital alveolar support technique, digital impression strategies for more predictable final restorations, a modified All-on-4 concept that retains teeth for natural dentofacial esthetics, and a new crown-lengthening approach for optimal soft tissue healing. "Biomaterials Update" explores gradient multilayered zirconia for expanding the indication of monolithic zirconia to the esthetic zone. These are but a sampling of the information-packed articles in this beautifully produced annual publication.
