The support of bounded saddles

Abstract

This article reviews the literature on planning the support of bounded saddles of removable partial dentures or fixed bridges. Three-dimensional photoelastic analysis was used to examine stresses on removable partial dentures of different designs, and possible model structure changes raised for further investigation.

The size of occlusal rest seats prepared for removable partial dentures

“…Modification of the supporting teeth ensures that the rest can be of adequate thickness to prevent its distortion under load; that the rest does not interfere with the occlusion, and that the tooth is axially loaded. [8][9][10][11][12][13][14] The rest seat also gives a positive position for its location and prevents the whole prosthesis from moving during functional loading. 15 The design and placement of rest seats in enamel, light cured resins, silver amalgam alloy or cast restorations is part of the undergraduate curricula in the UK and USA.…”
