Conventional Bridges: Impression Techniques course for Dental Practice
This session will outline the properties of various impression materials used to record tooth preparations for crown and bridgework. Factors influencing selection of appropriate impression material will also be discussed, as will various techniques which enhance accurate recording of surface detail.
Learning objectives
By the end of this session you will be able to:
- classify impressions materials and explain their advantages and disadvantages
- select an appropriate material to record impressions for crown and bridgework
- describe the different techniques for recording such impressions along with their limitations
- list techniques that aid accurate recording of subgingival margins
Accurate impressions are an absolute necessity when providing crown and bridgework. Failure to produce an accurate record can lead to a compromised restoration which may fail to be seated on the abutments and/or be associated with poor marginal integrity, which in turn can result in microleakage.

- knowledge of the different types of impression materials used in restorative dentistry
- knowledge of properties of an ideal impression material
- completed the e-Den sessions in Module 9 Replacement of teeth/Bridgework:
