Prototype importance for implant supported zirconia bridges: a case report

Abstract

Biocompatible esthetic restorations are necessary in order to obtain successful resultswith implant therapy. Monolithic zirconia is a more recently offered option to PFM andzirconia-ceramic prosthesis. The optical properties of zirconia have been greatly enhanced,approaching those of ceramics, while the monolithic nature of the prosthesis reduces thechance of fracture or chipping and improves its structural properties. The major drawbackof theses zirconia is mechanical and thermal problems that encountered when zirconiais exposed to hydrothermal aging due to the transformation of the metastable tetragonalzirconia into the monoclinic form. This case report describes 45 aged adult female patientwith anterior maxillary mobile teeth, after clinical and radiographical examination,extraction and socket preservation were done at periodontal department, 6 months laterimplant installed and after 3 months of healing, the patient referred to prosthodonticdepartment. Screw retained temporary prosthesis were fabricated, composite build upwere done intraorally for the temporary prosthesis to achieve the esthetic and functionalocclusion. Cement retained implant supported fixed prosthesis using monolithic zirconiawere cemented and no occlusal adjustment is needed thanks to the adjusted temporaryprosthesis which served as prototype for a zirconia bridge with functional occlusion
