The bilateral distal extension removable partial denture: mechanical problems and solutions.

Tbe bilateral distal extension removable partial denture has inherent problems of retention and stability, affecting not only the integrity of denture bearing tissues and associated structures, but also patient acceptance and compliance. This paper examines factors that contribute to and exacerbate the functional movement of free-end saddle prostheses, discusses techniques used to overcome these problems and lists alternative strategies for the management of the Kennedy class I patient.
