Equipoise: Removable Restorative Solutions for Today’s Dentistry

 

The Equipoise System provides you with a complete system for esthetic partial denture design from conventional to semi-precision milled and precision C&L attachment applications.

Equipoise Clasp Preparation Guidelines:

                                                                                                                                                                  The E-clasp is a lingual back-action clasp that is fully reciprocated, vertically and horizontally.

Rest Preparation:

The occlusal rest is prepared with a cylindrical diamond stone. On bicuspids the rest should be spoon-shaped and encompass 1/3 the mesiodistal width of the tooth and at least 2/3 of the buccolingual width. Rests on the incisors are prepared over the cingulum or on the incisal edge of the tooth. The cingulum rest should be at least 1 millimeter deep and one-half the width of the tooth mesiodistally away from the edentulous area. The incisal rest should be at least 1.5mm deep and 1.5mm wide.

Inter Proximal Preparation:

An interproximal access of at least 1mm is necessary to give the minor connector enough strength to support a well contoured rest. This preparation is made by removing 1/2 mm of enamel from the abutment and 1/2 mm enamel from the adjacent tooth. A 1mm tapered diamond stone is recommended. Rubber wheel or polish cut surfaces.

 

The Equipoise Balance of Force Principle

 The Equipoise principle of partial denture design protects, preserves and strengthens abutment teeth while directing all masticatory forces down the long axis of the abutment tooth. This is accomplished through the use of Equipoise Class II Lever design. The Class II lever design has the rest (fulcrum) opposite of the retentive tip of the clasp (resistance arm) and the denture base (the effort arm). The clasp arm always moves in the same direction as the denture base while directing all forces down the long axis of the retaining abutment tooth. With the Class II lever design you always obtain stability during mastication and retention only when needed against dislodging forces.

Equipoise C&E Milled Design

The C&E Milled Design features the application of a milled abutment crown (12 degree milled undercut) with a precision c-rest (for stabilization and reciprocation) and conventional E-clasp (for retension). This semi-precision shows no metal while maintaining proper contact with the adjacent tooth.
