- 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
