All indirect dental restorations
must be cemented for final delivery into the patient’s mouth. The question
arises, is the cementation of the indirect restoration the final step in the
procedure or is it just the beginning of the restoration’s clinical life?
Because of this question, clinicians must remember that with a variety of
all-ceramic materials available in today’s clinical practice it is vital to
understand what type of cement will provide the best opportunity for a positive
long-term outcome. Currently, there are four major cement categories: glass
ionomer cement, resin-modified glass ionomer cement, self-adhesive resin
cement, and adhesive resin cement. Selecting the right permanent cement can
often be confusing for clinicians given that multiple factors must be
considered, including: preparation design, required bond strength, restorative
material (substrate), ability to isolate the field, and esthetics.
At the conclusion of this session, attendees should be able to:
- Understand how to match cement to crown material for optimum results.
- Compare the four major categories of final cements.
- Understand clinical techniques to make cementation of indirect restorations simpler and more predictable.
