Bridges
A bridge is
one of a number of alternatives for replacing
missing teeth.
It is essential to replace missing teeth
due to the potential problems described
in the section 'Missing one or more teeth'
resulting in further tooth loss.
A bridge replaces a missing tooth by means
of two, or more, crowns which are 'bridged'
by an additional tooth over the site of
the missing tooth, as shown in the following
diagram,
 
Indications
- Replacement of missing teeth
- There the adjacent teeth need crowns
Key Benefits
- Replacement tooth, or teeth

- Support and protection to compromised
teeth

function

The procedure requires two
appointments, as per crowns (click). At
the first appointment the abutment teeth
are prepared by circumferential reduction
to make room for the supporting crowns.
An impression (or, mould) is then taken
for fabrication at a laboratory, and a plastic
temporary bridge fitted for the interim
period. Laboratory fabrication takes approximately
1 weeks. At the subsequent visit, the temporary
bridge is removed and the final bridge is
permanently cemented into place.
