•A
74-year-old woman attended the surgery complaining of a fractured
UR1. The patient was examined and it was found that the UR1 has
broken off completely at gum level. The patient had no pain and
was only concerned about the unacceptable appearance. A pariapical
x-ray revealed no abnormalities.
•The
tooth was still vital, without a root canal filling. After all
treatment options were discussed, it was decided to build up the
tooth with a fibre-reinforced composite as the patient was loath
to leave the surgery
without an anterior central incisor.
•The
occlusion was checked with articulation paper to make sure the
fibre reinforced composite build up would not interfere with the
occlusion. A small groove preparation was completed on the palatal
side of the UL1, just about one mm – enough to accommodate the
C&B Everstick glass fibre strip.
|
|||
•The
required length of glass fibre strip was then measured in the mouth.
For this purpose an endodontic reamer and stop was used. The
required length of C&B Everstick was then cut with a pair of
scissors. Unnecessary exposure to light should be avoided and it is
recommended that the fibre strips should be returned to the packet
straight after cutting .
•Both
the prepared groove on the UL1 and the visible surface of the
fractured UR1 were then treated with 37% phosphoric acid for 10
seconds. Solobond bonding agent was then applied and light cured
according to the manufacturers instructions.
•The
UR1 was build up with a ¾ mm-thick layer of 3M Z100 MP resin based
restorative material. The glass fibre strip was secured with a
flowable composite into the groove on the palatal side of the UL1.
The free end of the glass fibre strip extending over the UR1 was
flared slightly to provide a larger surface area for the Z100
composite to bond to. Layer by layer the composite was then build up
into the shape of an anterior incisor. Care was taken that all the
fibres were covered with a thin layer of composite (also on the
palatal surface of the UL1.).
|
|||
•The
constructed UR1 was then shaped with burs, stones and discs and
finally polished to give it a smooth, shiny and natural appearance.
•The
patient was shown how to maintain the oral hygiene in this difficult
to clean area by using super floss. The super floss can easily be
threaded through the triangular space between the gingiva and the
fibre strip. A follow up appointment was arranged in a week’s time
for more polishing if necessary.
•The
patient left the surgery 45 minutes later, smiling and very content
with her restored dentition.
•This
case was a very good example where stick fibre technology was the
number one choice of treatment:
•The
patient was provided with an anterior tooth there and then.
•Strong
and durable glass fibre reinforcement.
•Minimally
invasive.
•Metal-free
and aesthetically pleasing.
•Cost
effective for both dentist and patient. Direct
and Indirect.
