The use of all-ceramic crowns offers the potential for improved aesthetic results compared to conventional ceramometal crowns. Silica/glass-based all-ceramic crowns are more translucent than alumina or zirconia-based crowns and therefore have better optical properties. However, they are mechanically weaker and need to be used in conjunction with resin bonding cements. It is accepted that adhesion between ceramics and resin cements is provided by two major mechanisms namely micromechanical attachment and chemical bonding. Due to its resistance to aggressive chemical agents, chemical bonding of zirconia is difficult when compared to silica-based ceramics materials.
In this paper, we discuss the luting modalities of both glass ceramics and zirconia based ceramics through a clinical report. It describes a case of rehabilitation of a missing lateral incisor and a peg lateral incisor using zirconia Cantilever Bridge and a ceramic veneer. Depending on material properties, the zirconia based restoration was mechanically bonded meanwhile the ceramic veneer was chemically bonded. The final result was esthetically acceptable and the patient was satisfied.
