The philosophy of restorative
dentistry has completely changed during the last decades.
There are basically two important factors, which are to blame
for this.
1 - The severe caries decline observed in the industrialized countries.
2 - the available reliable dental
adhesives.
As a consequence of this, the dentist is more often confronted with small
lesions.
Furthermore, the cavity preparation rules are not dictated
anymore mainly by the materials characteristics, but by the extension
of the lesion. The minimally invasive approach is the key to success,
because we can conserve as much sound tooth substance as possible. Sound
tooth substance is only removed to get access to the lesion and to be
able to inspect it.
Adhesive technology allows to reinforce the dental unit,
which enables the dentist to truly restore the tooth to its
original strength. For the patients, esthetics are the most
evident advantages of the adhesive
dentistry and generally they are more satisfied with tooth
colored restorations .
Also in the posterior segment, aesthetics can be easily achieved
with composite
resins, however there are some rules and limitations to
be respected.
