| Surface retained bridge
Step-by-step:
- An 18-year old woman with congenitally missing maxillary lateral incisors
is to be treated with implant crowns.
- After the implant surgery, the missing teeth were replaced with a
Perma fiber-reinforced
surface retained Maryland bridge. The use of transparent fiber-reinforced
composite frame instead of a cast metal frame for the bridge, was justified
by the fact that the fiber-reinforced composite
frame offers superior cosmetic value, and that the composite resin luting
cements adhere better to fiber-reinforced
composite than they do to the metal. The bridge covered six teeth in
the palatinal area.
- The frame of the bridge was made of Triad Gel using
Perma fiber reinforcement. The proximal
spaces were carefully kept open to avoid the need for chairside preparation.
The attachment surface area was made as large as possible.
- Once the bridge was in place and luted, it exhibited highly aesthetic
features. Note the proximal spaces; there is no need for any chairside
preparation, which could easily break the fibers.
- A surface retained bridge can achieve both a superb aesthetic finish
and excellent functional performance.
