Dentaltown April 2022 - 47

Maxillary and mandibular stone casts
and wax rims were created using conventional
protocols (Fig. 9). The wax rims were inserted
into the patient's mouth to perform any
needed corrections to the midline, position
of the teeth, centric relation (CR) or OVD.
A bite registration (Virtual CADBite, Ivoclar)
was completed to record the relationship
between the maxilla and mandible (Fig. 10)
and to provide information that would be
critical for initial placement of the denture
teeth-incisal length, labial position and
occlusal plane, as well as vertical dimension
and centric occlusion.
In a conventional case, the dentist would
send the bite registration to the lab for design
of the denture teeth and request 3D-printed
try-in dentures, which would help ensure
the midline was correct and the patient
approved of the aesthetics and phonetics of
the planned prostheses before the laboratory
milled the final dentures. It must be noted
that in this scenario, depending on the degree
of changes needed for an optimal fit, the
technology to print multiple try-in dentures
is not cost-prohibitive and makes the option
of multiple try-in dentures feasible.
Because this case was unique in that
the final prosthetic had to be completed in
a single visit, the maxillary and mandibular
definitive casts as well as the labial/buccal
surfaces of the wax rim bite registration
were scanned in the in-house laboratory and
the scans uploaded into the CAD software
program (Fig. 11) for virtual articulation
of the wax rims (3Shape Ivotion, 3Shape),
virtual setup of the denture teeth and CAD
design of the complete dentures (Figs. 12-14).
Milling the definitive prostheses
The subtractive manufacturing digital
denture system used for this case (Ivotion,
Ivoclar) offers two types of definitive complete-denture
protocols.
One protocol is a denture base milled
from a prepolymerized block of polymethyl
methacrylate (Ivobase CAD, Ivoclar) along
with milled denture teeth from a block of
dual cross-linked material (SR Vivodent
CAD, Ivoclar). The milled denture teeth are
then bonded into the milled recesses using

a special PMMA bond material (Ivobase
CAD Bond, Ivoclar). The dentures are
then finished and polished and sent to the
prescribing dentist for placement.
The second protocol is a monolithic
denture milled from a bicolor disk (Ivotion).
One half of the disc is the denture base
material made of high-impact optimized
PMMA while the other half is the tooth
material made of highly cross-linked PMMA
with no filler (Fig. 15). After the virtual
design of the dentures on the CAD software
(3Shape), the bicolor disk is milled through
a single, uninterrupted milling process, then
finished, polished and sent to the prescribing
dentist for placement.
