WHEN
• The oral and general health of the patient.
• The condition of the remaining teeth and tooth tissues, the periodontal condition and oral hygiene maintenance.
• Analysis of the benefits, disadvantages and long-term consequences of providing a crown or fixed prosthesis.
• Complications which limit the likelihood of clinical success.
WHY
CROWNS:
• To restore the form, function and
appearance of teeth which are badly
broken down, worn or fractured
to the extent that simpler forms of
restorations are contraindicated or
have been found to fail in clinical
service.
• To improve the form and appearance
of unsightly teeth which cannot
be managed by more conservative
cosmetic procedures.
• To reduce the risk of fractures
occurring in extensively restored teeth
including endodontically treated
posterior teeth.
• More rarely, to alter significantly the
shape, size and inclination of teeth for
cosmetic and functional purposes.
• To restore a dental implant.

FIXED BRIDGES:

stability.
