A UNIQUE SOLUTION By Sol Soroca - C.D.T., Pres. Flexite
Our patient is a male in his late fifties. He has four remaining lower anterior teeth
that have been sheered down by attrition. The Alveolar bone appears to be firm and
the teeth are solid.
We have several choices:
(1) Leave the teeth as is and make a simple lower partial. But how would you clasp
(2) A couple of buccal arms? We could do a lower acrylic partial with silicone gaskets.
But silicone is hard to keep clean and is known to pickup bacteria. The anterior teeth
would still be unesthetic.
(3) We could propose individual posts and porcelain crowns. Do we splint the crowns
and consider a stress-breaker type of attachment? Sounds plausible, but can the patient
afford the costs and be willing to go through the process? The answer is no! So what is
the next best prognosis? Here's what we recommended to our friend Stewart.
We start with an excellent elastic impression from the dentist.
Models poured and articulated. Pins inserted in elastic
impression for stabilization.
Note excessive abrasion on occlusals.
Anterior undercuts blocked out for duplication.
Bite block made for bite registration.
Anterior waxup with posterior extensions
transferred to duplicated model.
Note extensions on saddle connecting to anteriors.
Note flat sheet of wax to form sprue and concavity
of wax in entry area. Note 1/2 inch of wax which
will be softened over Bunsen burner and put into
Note convexity shape of wax in entry hole. By
compressing other half of flask against the soft
wax we create the convexity.
Anteriors are injected with Flexite MP or Acetal
tooth shade plastic. (Completed and Polished)
Lateral, cuspid and first bicuspid setup for initial
tryin with wax rim.
Completed setup and waxup.
Lingual view of waxup prior to investing in flask.
View of flasked case and method of spruing.
One piece overdenture in pre-completed stage.

Patient with lower lip extended.
We have created an overdenture which gives the appearance of a separate
lower anterior bridge and a separate lower partial. This is made possible
with our Flexite thermoplastics which have compatible tooth color and tissue
shaded plastics. During the injection process there is complete fusion between
the tooth color and the pink color. Anterior shades can be modified by adding
our bonding agent and tooth color acrylics to the labial surface.
No tooth grinding.
No discomfort to the patient.
Restores lower anterior esthetics.
Moderate cost to the patient.
Hygienic.(Easier access to maintain cleanliness)
