Fixed
Bridges
Bridges
are restorations cemented in place and used to replace missing
teeth. This is just one of several options for replacing missing
teeth, with implants and dentures being the others. The material
options for bridges is the same for that of crowns, however the
longer the span of the bridge (space between abutment teeth), the
more flex it has and the higher the risk for porcelain fracture.
Bridges work best when there are solid teeth on either side of the
missing tooth. Depending on the quality of the abutment teeth
(teeth used as anchors for the bridge), and the number of pontics
(portion that replaces a tooth) the preparations on abutments may
be minimally invasive (similar to a veneer), or more invasive, like
a crown. The abutment teeth may be natural teeth or implants. The
key for longevity of bridge work is cleanliness, and strong
abutment teeth.
Case #4
- 5 Unit Bridge
This
patient had an existing bridge and one of the anchor teeth rotted
out underneath. In order to preserve this patient's smile the old
bridge was removed, bad tooth extracted, and new bridge prepared.
Final result was a great smile. The photos show the process from
initial bridge to final bridge.
Case #3
- 3 Unit Hybrid Bridge
For
this case, the abutment tooth in front of the space was a virgin
tooth, and the tooth behind the space in pretty good shape. To
minimize loss of healthy tooth structure, a combination between a
Maryland Bridge (metal sleeves that wrap around the back side of
the tooth for anchorage), and a conventional bridge (traditional
crown preps). Although this left a bit of a transition line between
the pontic and front abutment tooth, the bridge preparation was
very conservative.
Case #2
- 3 Unit Hygienic Bridge
This
individual wanted a single tooth replaced on the bottom left. As
cosmetics were not of a huge concern here, a hygienic bridge was
fabricate. This bridge is called a hygienic design due to the space
left between the gum tissue and the pontic (part of bridge
replacing the missing tooth). This allows for easier cleaning under
the pontic and better monitoring of the bridge for possible break
down and repair in the future.
Case #1
- 5 Unit Implant Bridge.
This
individual was missing 5 front teeth and did not want a removable
partial denture anymore. To provide a fixed restoration implant
placement was chosen (span to long to provide a long lasting bridge
on natural teeth). Three implants were placed and a 5 unit bridge
fabricated to be cemented to them.
