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 

the teeth? 


(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

entry area.



 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 before inserting partial.




                Patient with lower lip extended.




                              Happy patient!



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.



 Non invasive.

 No tooth grinding.

 No discomfort to the patient.

 Restores lower anterior esthetics.

 Moderate cost to the patient.

 Hygienic.(Easier access to maintain cleanliness)
