Cast Metal Partial Dentures

Cast Metal Partial Dentures, as the name suggested, have a metal frame work on which the acrylic and teeth are built on.  It is a lot more stable in the mouth since the metal arms of the partial directly hook onto the teeth in the mouth. The disadvantages are that some of the natural teeth may have to be modified to make room for the metal arms from the cast metal partial dentures and may not be aesthetically pleasing since metal parts may be visible when one smiles. And the teeth where the metal arms may lean on can become mobile over time.

Transitional Partial Dentures

Transitional Partial Dentures can be used to replace one or more missing teeth temporarily until one can decide to do a more permanent replacement such as cast metal partial denture or a fixed porcelain bridgework (if the space is restorable with the bridgework).  It can be used as a more permanent partial denture also since more teeth can be added onto the existing transitional partial denture when additional teeth are lost soon after.  If one has already lost a significant number of teeth and is planning to take out more teeth in the immediate future, transitional partial denture is the best way to start.  Transitional partial dentures have little or no metal. Transitional partial dentures will not be as stable as the Cast Metal Partial Dentures and can cause the eventual mobility of the teeth where the metal arms lean or clasp onto.

Complete Dentures

Complete Dentures are for those who no longer have any teeth left in their mouth. The advantages of wearing complete dentures include being able to chew food more efficiently and looking younger again.  The disadvantage is the instability of these dentures.  Since there are no stationary natural teeth for the dentures to hold onto, they tend to move around in the mouth more than partial dentures.  The lower dentures have the highest rate of movement due to the powerful tongue muscle.  Additional adhesive such as Fixodent may be needed to achieve better stability.  Also, if one has been without teeth for a long time or has never worn any type of dentures previously, it will take time to get used to living with artificial prosthesis in one’s mouth.  In addition, one will have to re-learn the basic functions such as eating and speaking with the dentures.
