PRINCIPLES OF A REMOVABLE PARTIAL DENTURE
PRINCIPLES OF A REMOVABLE PARTIAL DENTURE
A denture should be designed to obtain a balance between mechanical and biological factors. A. H. Schmidt in 1956 stated the following five principle to be considered during the fabrication of a removable partial denture.
They are:
. The dentist must have a thorough knowledge of both the mechanical and biologic factors involved in removable partial denture design. He must know about the various forces acting on the denture and soft tissues and their response to these forces.
. The treatment plan must be based on a complete examination and diagnosis of the individual patient. Any negligence in the appropriate diagnosis will lead to failure of the prosthesis.
. The dentist must correlate the pertinent factors and determine a proper plan o~ treatment. He must examine the existing oral condition and do the necessary modifications before designing a removable partial denture.
. A removable partial denture should restore form and function without injury to the remaining oral structure. It should produce adequate aesthetics and function without compromising on the health of the soft tissues.
. A removable partial denture is a form of treatment and not a cure. Even after insertion, the patient should be recalled and reviewed to ensure success of the treatment.

Direct retention
a. Retention should not be considered the prime objective of design
1. The main objective should be the restoration of function and appearance and the maintenance of comfort with great emphasis on preservation of the health and integrity of all the oral structures that remain.
b. close adaptation and proper contour of an adequately extended denture base and accurate fit of the framework against multiple, properly prepared guide planes should be used to help the retentive clasp antis retain the prosthesis.
