Definition
A complete denture (CD) is a removable dental prosthesis that replaces all teeth and associated structures in a completely edentulous arch and is supported entirely by the oral mucosa and underlying bone.
Principles of Successful Complete Dentures
Unlike RPDs, complete dentures are fully mucosa-supported, so biomechanics differ significantly.
