Identifying the aesthetic and functional determinants in the collapsed dentition.

This patient's treatment involved a complex diagnostic challenge, as well as a challenging clinical sequence due to the utilization of immediate implant placement and restoration after extraction along with immediate prosthodontic restoration with sinus elevation with bone grafting. The inability to have diagnostic patient wax try-ins required a detailed and exacting diagnostic work-up which included significant laboratory diagnostic wax-ups. The utilization of the ACP Parameters of Care for Partial Edentulism for a PDI Class IV patient provided a framework in which care could be planned and executed with confidence. The availability of various reconstructive materials and techniques to create a seamless restorative result is essential to the success of this type of advanced treatment.
