ABSTRACT
Most removable partial denture frameworks constructed today are one-piece castings. This article presents the Component Partial, a removable partial denture in which the framework is constructed in pieces. Such construction ensures a more accurate fit of the RPD.

A laboratory study was designed to determine the effect of ""deactivation'' of stressbreakers on abutment tooth movement and ridge displacement. The Ticonium hidden-lock and the pin-Dalbo precision stressbreakers were tested. Results showed that ridge displacement was significantly decreased when the Dalbo was made rigid, and tooth movement was significantly decreased (during bilateral loading) when the hidden lock was made rigid.

A modified hygrosopic gold casting technique has been described. It utilizes a dual-wax pattern with controlled amounts of water added to the setting investment to better influence both the location and amount of investment expansion. This technique has been used since 1970 with excellent clinical results.
