Metal Denture Base
Posted on 02/17/2012
Metal denture bases are indicated in situations of severe occlusal space limitations where no acrylic bulk is an option. Typically, they are used for tooth supported segments (i.e. metal base sits between two existing teeth) and the residual ridge is well healed. There is no acrylic attached to the denture bases aside from actual denture teeth which are joined using beads, nailheads or wire loops. Tube teeth are not recommended due to high incidence of fracture.
Among the design elements of the metal denture bases are:
1. No relief is placed under the metal denture base
2. No internal finish lines
3. External finish lines are optional and depend on method of tooth replacement
The major disadvantage of the metal base is the fact that it cannot be relined, unlike acrylic bases. This point should be well considered before designing the metal base.
