DR. ASHISH RAYAREL, UK

Course Objectives

By the time the delegates has completed this cours will...:

• Critique failures in Maryland bridge design
• Evaluate the criteria determining the type of Maryland bridge prescribed
• Describe the applications for: single cantilever, fixed-moveable and fixed-fixed designs
• Incorporate design features to resist forces: lingually, occlusally and coronally
• Produce preparations showing gingival finish lines of the correct depth and position
• Demonstrate guide planes to increase the wing height and give retention/resistance form
• Present proximal grooves parallel to the tooth long axis and having mesial and distal walls
• Confine the lingual groove within the gingival and occlusal finish lines
• Respect the preservation of the grooves‘ lingual walls when placing rest seats
• Confirm fixed-fixed bridge design features show a common line of draw on all abutments

Course Aim

Attending this course will help delegates...:

• Recognise the causes of Maryland bridge failure
• Determine the features which are ideal in Maryland bridge design
• Understand the forces which can displace the bridge
• Describe how the design features resist the displacing forces
• Appreciate why we must maintain enamel in the preparation
• Realise the objective of the proximal guide plane
• Predict the consequences of not temporizing the preparation
• Discuss the options available for creating space for the bridge
• Identify the determinants for placement of the occlusal finish line in maxillary bridges
