finishing and polishing.
The finished case can also
be checked in the lab
with the
Alma Gauge in order to establish that
no flasking error has taken place and
the teeth have been processed to the
prescribed measurements.
V. Weak Incisive Papilla or
Central Position
Occasionally, the incisive papilla
may be rather flat, or in the lower
ridge, the central position may not be
obvious. In these circumstances the
Alma Gauge measurements can be
enhanced by marking a spot in the
patients mouth that appears central in
position. This applies to both the
upper or the lower arch. A tissue
marking pen can be used for this
mark before impressions are taken.
Accurate transfer of this mark from
the tissue surface will help insure that
all Alma Gauge recordings will be
consistent.
The technician in the laboratory
can perform a similar task by placing
a fresh mark over the spots, allowing
a mark to be passed onto the wax
registration rims and later on to the
try-ins. All Alma Gauge readings per-
formed during a case will be taken
from the same position.
VI. Denture Duplication
Technique
With the assistance of the Alma
Gauge, a reliable technique can be
used that will allow dentist and tech-
nician to create an accurate duplica-
tion of existing dentures. The Alma
Gauge confirms the exact position of
the teeth relative to the soft tissues - a
critical first step in denture reproduc-
tion.
First, examine
the mouth and the
existing denture.
Check the vertical
dimension and
amount of free-
way space. If
these measure-
ments are found
to be adequate,
Alma Gauge measurements are taken
of both the upper and lower existing
dentures and recorded for use by the
technician. Reline type impressions
are then taken inside the old dentures,
preferably with the patient gently bit-
ing in centric occlusion. A wax bite of
this position can be recorded if it is
felt that the teeth cannot be easily
occluded by the technician. Alginate
impressions can also be taken of the
existing dentures in order to allow the
laboratory to see the relative positions
of the teeth to each other.
The technician can now pour a
model and articulate the dentures in
the recorded occlusal relationship. The
old dentures can be returned to the
patient because the laboratory techni-
cian has sufficient information to set
the teeth in the desired position.
With the use of the Alma Gauge
measurements, the anterior teeth can
be placed in exactly the same position
as the old denture. Also, by referring
to the models of the old dentures, it is
easy to arrange the teeth in the same
type of relationship. Finally, at the try-
in stage the dentist can confirm that the
position of teeth is the same as that of
the old dentures.
VII. Lost Denture Reproduction
With Alma Gauge measurements
on file, patients who misplace or break
their denture can now receive a tem-
porary replacement in less time.
Anterior tooth position can be quickly
reestablished and a decision made as
to an interim prosthesis.
