Problem: Early loss of the primary anteriors due to severe
caries or trauma.
Solution: Replace the damaged teeth with a beautiful fixed
interim primary bridge.
Pediatric space management is often the key to preventing a serious
malocclusion in the permanent dentition. The early loss of primary anteriors
can result in the development of speech problems, tongue thrusting, abnormal
chewing and swallowing problems; abnormal growth of the maxilla and the
mandible; and even the development of a permanent of a permanent Class
II dentofacial abnormality. If the permanent teeth are not going to erupt
in six months, appliance therapy to maintain the space indicated. If
space loss has already occurred, a space-regaining device should be used
prior to placing this appliance.
Our clinical case exemplifies the premature loss of anterior teeth due
to Baby Bottle Syndrome. On the day of the extraction, the doctor delivered
a Groper Fixed Anterior Bridge. Esthetics and strength are the key advantages
to this popular design. The anterior bridge is made extra strong by attaching
each tooth separately to a specially designed, stainless steel pad (a
Space Maintainers exclusive). Each unit is then welded and soldered to
the arch wire. As you can see, within a week, the tissue is healed and
the patient is able to maintain normal speech, function and esthetics.
Treatment Procedures:
- Start by taking an accurate alginate impression of both the upper
and the lower arch and pour them up in yellow stone. Taking these impressions
prior to extracting the teeth that you intend to replace is optional.
Some clinicians like to deliver the appliance immediately and others
prefer to let the ridge heal first.
- Take a centric occlusion bite relationship. This must be done to
assure that there is an appropriate amount of occlusal clearance to
construct the appliance. It is also essential to properly set the teeth
in the best position.
- This is a fixed appliance. Both bands and stainless steel crowns
are acceptable. When using your own bands, take your impression and
pour it up without the bands in place. Let the lab fit your bands on
the stone cast. To guarantee the fit, the teeth to be banded must be
fully erupted. When using crowns, take the impressions and pour it
up with the crowns in place.
- Select a shade. Because children's teeth are very white, your standard
Bioform and Vita shade guides will generally not work. Space Maintainers
has a special Pedo-Shade Guide that will allow you to select an appropriate
shade.
- Fill out your lab slip completely. Mark your bands left and right.
Wrap your models and bite relationship separately to protect against
breakage.
- Cement the materials with glass ionomer cement. An appliance should
be used to maintain the space until the beginning of the eruption of
the adult anteriors. It may be necessary to replace this appliance
during the course of treatment, if it is going to be years before the
adult teeth are going to erupt.
