Metal base dentures
There are two types of metal dentures: Standard and Modified. Standard metal dentures do have metal in direct contact with a portion of the gum, but the metal used are non-allergic. The modified metal denture is very similar apart from one difference – it does not have any metal in direct contact with the gum. A plastic liner is used between the metal structure of the denture and the gum. Both hard and soft plastic can be used. Soft is the preferred liner, but does need to be relined every year.
Why would I need metal dentures?
Some cases will require the denture to be narrow. If they are made out of plastic, they tend to be very weak and can easily break. Metal dentures offer the required strength in such cases.
Lower jaws can be very problematic when they lose teeth. Using a metal denture can add stability to the jaw and will also be more comfortable for the patient.
