During the process of losing teeth, the fabrication of an immediate removable complete denture usually plays an important role. The path from natural to a prosthetic occlusal system separates itself into a phased and a non-phased treatment. Various patient-related factors are of importance in the decisionmaking process for a phased or a non-phased treatment, such as the patient’s time available, the medical indication, the complexity of the natural occlusal system, and the motivation for treatment. A positive result can be more confidently predicted in the case of a phased treatment than a non-phased treatment. Placement of an immediate removable complete denture requires immediate aftercare. Particularly in the case of non-phased treatment, the fabrication of a new complete removable denture will be required within 1 year.
