Bonded ceramics and especially porcelain veneers have long been
regarded as a less invasive method of fixed prosthodontic treatment.
The guidelines for tooth preparation associated with traditional
full crowns are long established; unfortunately, there are no such
preparation guidelines regarding bonded ceramics, and a number
of different approaches have been described in the literature. It may
seem that deviating from a full-crown preparation will automatically
lead to a more minimally invasive treatment. However, when scrutinizing
the photographs and procedures described in the literature,
significant tooth reduction can often be seen even if the stated goals
were to remove as little tooth substance as possible and confine the
preparation to enamel. Thus, this paper discusses minimally invasive
approaches to tooth preparation when using bonded ceramic restorations.
