Acrylic Partials are not as strong and tend to break more often and more easily.
Cast partials are not as bulky, so you will have more room for your tongue to move while eating and speaking.
It is a good idea for a couple of reasons.:
1. It will help maintain the position of the natural teeth and stop them from moving or falling over.
Cast Metal Partials are supported by the teeth and sit firmly in place. Acrylic Partials sit on the tissue and because of that, there is movement. That movement allows the clasps to move up and down and can cause damage to the tissue or the tooth it is in contact with. The movement also decreases efficiency when chewing.
Once the natural teeth are removed, the bone “shrinks” because there is less blood flow and bone stimulation to maintain the bone. If you are healthy and maintain your weight, it shrinks slowly. If you get sick or loose weight, the bone shrinks faster.
If you put weight back on, the bone doesn’t regenerate, and the dentures stay loose.
Most people need to come in for permanent relines around the 2 to 3 year mark because the bone never stops shrinking. Some people go longer, some need relines sooner.
Check ups are usually suggested once a year.
