Recentry, the opportunity, which the ceramic materials such as zirconia and lithium disilicate are used as the
material of the abutments and superstructure, has been increased. This is because they are better in esthetics
and biocompatibility as compared to titaniums.
Because each of these ceramic materials has both advantages and disadvantages, it is necessary to distinguish
on a case-by-case basis.
Three cases of the implant prosthesis, in which zirconia and lithium disilicate are used are reported and
discussed.
