rule by a margin of any significance is almost
certain to invite problems. 3 Inadequate
abutment support had led to delamination of
ceramic veneer from metal sub structure and
periodontal problem in abutment teeth. In this
case, a removable prosthesis was indicated as
these were insufficient number of supporting
natural teeth and large edentulous spans for
planning a fixed prosthesis. All the abutment
teeth were strengthened by splinting and full
veneer crowns. Double palatal strap major
connector for Kennedy’s class 3 modification 1,
was made as it preserved natural thermal
stimulation and taste sensation for the patient .
The quadrilateral configuration of the partial
denture effectively controlled stresses by
judiciously distributing occlusal stresses on the
abutment teeth. Quadrilateral clasping consists
of a retentive clasp at each end of edentulous
space on the terminal abutment tooth thus
providing retention and stability. Parallel guide
planes were created on the abutment for the
desired path of insertion and withdrawal. Rest
seats helped to control stresses by directing
forces transmitting to abutment teeth along the
long axis of the teeth as the periodontal
membrane is capable of withstanding vertical
forces of far greater magnitude th
