A modified layering technique to enhance fluorescence in glass-infiltrated aluminum oxide ceramic restorations: Case report
Komine, Futoshi / Blatz, Markus B. / Yamamoto, Shogo / Matsumura, Hideo
Fluorescence, opalescence, and translucency are critical for restorative materials to mimic the optical properties and appearance of natural teeth. This case report describes the restoration of multiple anterior teeth with CAD/CAM-fabricated glass-infiltrated aluminum oxide ceramic (In-Ceram Alumina, Vita Zahnfabrik) crowns and illustrates the technical steps to achieve an adequate amount of fluorescence in the ceramic veneering material. CAD/CAM aluminum oxide ceramic copings and frameworks can be predictable and successful when replacing missing tooth structure and imitating optical properties of natural teeth. A modified layering technique enhances fluorescence within the veneering ceramic and provides an esthetic appearance of glass-infiltrated aluminum oxide ceramic restorations.
