Four-year follow-up of the rehabilitation of a mandibular arch with a cementable zirconia-reinforced fixed dental prosthesis: A clinical report

Implant-supported prostheses have been used extensively to rehabilitate completely edentulous arches. Although combinations of different restorative materials have reportedly been used to fabricate such prostheses, a metal framework is usually chosen for acrylic resin reinforcement. However, cost and the frequent need to section and solder to attain a passive framework fit are disadvantages for using metal. Zirconia has been used widely in restorative dentistry as an alternative to metal. This clinical report describes the fabrication of a zirconia-reinforced cementable fixed dental prosthesis with a 4-year follow-up.
