Systematic Total Rehabilitation is very challenging, especially in patients with Periodontal Disease with Loss of Supporting Structures. Precise Treatment Planning is essential. The Treatment of Periodontal Disease begins after Conservative Pretreatment. It is not possible to predict the Soft Tissue Esthetic Outcome before the Healing Process is completed. We selected Endosteal Implants for the Augmentation of Lost Support Zones in this Atrophic Mandible. A Three-Dimensional Analysis was performed as the Basis for Navigated Implantation. After Completion of the Periodontal Treatment and Implantation, the patient must wait for approximately 6 months for the Completion of the Healing Process before Prosthetic Reconstruction Procedures can be initiated.
