Cast Partial Dentures

Statics - The fundamental principles

Kennedy Class I

Example:

  • Kennedy Class I
  • bilateral, free-end saddle

Äußerer Belastungspunkt

Verkürzung

Äußerer Belastungspunkt

Klammerspitze

In this case it is not possible to achieve an ideal static solution. The same procedure: Indirect occlusal support

Ausdehnung der Sattelteile
(Schneeschuheffekt)

Distales Satteldrittel
außer Funktion

Breite
Transversalverbindung

Kippmeider einsetzen

Wide transverse connector. Maximum extension of the saddles.

Example:

  • Kennedy Class I
  • bilateral, free-end saddle

Widerstandshebel

Klammerspitze

Angriffshebel

In this case, a slightly better static solution is possible. Rotation angle R2 across the tuberosity, the saddle area is extended generously.

The denture base can be constructed in a slightly more delicate design.
