Operative dentistry is the science and art

Defect that occurs in the hard tooth

Operative dentistry
1. Caries
2. Discolored teeth
3. Congenetically
malformed teeth
4. Fractured teeth
5. Diastema
closure
7. Old restoration
replacement or
repair
Dental restorations or fillings are used to
restore function and integrity to the
structure of teeth
1.
Direct restoration
2.
Indirect restoration
Direct restorations are
performed by placing
the restorative
material directly into
tooth cavity
Examples: amalgam,
glass ionomers, resin
ionomers & composite
fillings
Indirect restorations involve materials that have
been fabricated outside the mouth
Examples include: inlays, onlays, veneers,
crowns and bridges
An intracoronal
restoration
prepared outside
the mouth and
luted into the
cavity
An extension of an
inlay that covers
some, but not the
entire, occlusal
surface of the
tooth
Development of materials and operative
techniques to bond restorative materials
completely to tissues of teeth
1. Reduce the
necessity for
extensive tooth
preparation
2. Strengthen the
remaining tooth
structure
3. Less microleakage
& less recurrent
caries
4. increased retention of restoration
