E-clasps are designed on the mesial or distal aspect of the teeth facing the edentulous area. It is a lingual back-action clasp that is fully reciprocated, vertically and horizontally. The clasp always moves in the same direction as the denture base while directing all forces down the long axis of the retaining abutment tooth. Equipoise clasp are placed on canine and premolars, in clinical cases of Kennedy Class I and II.

When existing abutments are used, a rest and guide plane are created in the abutment teeth opposite the edentulous area. This technique enables the abutment tooth to move properly during mastication along the long axis eliminating destructive horizontal forces. Retention is achieved with a back action clasp that engages the undercut facing the edentulous area. The clasp moves away from the undercut during mastication and passively retains the abutment tooth. Protection and preservation of the abutment teeth and function are most important, and can be easily and readily acquired if four simple engineering laws are applied with understanding and the basic physiology of the tooth is not violated. Without proper tooth preparation, or when indicated, properly contoured crowns, a RPD can not function properly. Equipoise® designed partials can easily be incorporated within your partial combination cases.
