Course Aims

The morning session will consist of a gold preps lecture and the afternoon session will be a practical covering gold preps, 3/4 crowns & 7/8 crowns.

Attending this course module will help delegate to:

• Appreciate the exceptional longevity of gold preparations
• Understand their aesthetic limitations, especially in the lower dentition
• Describe their use in bridge abutments
• Conceptualise the design features for gold preparations
• Introduce the concepts of:  sharp internal line angles, the flare and the bevelled shoulder
• Discuss the properties the occlusal offset furnishes to the preparation
• Distinguish the clinical applications of the gold onlay and the 3/4 crown
• Appreciate the conservation of tooth material offered by full gold and 7/8 crowns

Course Objectives

• Appropriately select burs which produce sharp internal line angles and flared margins
• Visualize a 60 axial inclination for all features of the preparation
• Demonstrate grooves which are positioned correctly and have a line of draw
• Produce an occlusal offset which follows the buccal finish line with the correct angulation
• Demonstrate the preparation of a bevelled shoulder for gold onlays
• Prepare restorations showing the correct planar reduction with ideal tooth removal
• Demonstrate the correct placement of the functional cusp bevel
• Reproduce the boxes to show both proximal and gingival flare
• Appreciate the placement of the facial finishing bevel and the palatal supragingival chamfer
• Respect the demand gold preparations place on the operator
