Course Objectives

 By the time the delegates have completed this course 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 a draw on all abutments

Course Aim

 Attending this course will help delegates...:

• Ensure Maryland bridges works - the use of minimal enamel preps inc grooves and rest seats to create the predictability you desire, theory and practical on phantom heads
• 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
