The milled implant-supported prosthesis: a treatment alternative for the edentulous mandible

The milled implant-supported prosthesis offers the benefits of fixed and removable restorations. Its infrastructure provides the same rigidity as the fixed restoration, due to the precise fit to the superstructure that is removable to promote adequate access for hygiene, yet provides lip support and maintains close contact with the soft tissues. These advantages enhance phonetics, aesthetics, correct lip support, and maintenance. The learning objective of this article is to discuss the indications for milled implant-supported restorations, review the scientific background of materials and techniques utilized, and describe the clinical and laboratory procedures involved. An uncomplicated and cost-effective impression technique is outlined, and the numerous steps of infra- and superstructure fabrication are presented.
