Repeatable predictability in impressioning is not only possible, but can be easily achieved with a fundamental knowledge of the materials that a clinician chooses and an understanding of basic clinical procedures.

This presentation will explain the clinical benefits of polyether and silicone based impression materials. A discussion of what tray material used in various tray types will ensure a result that is free from distortion. Timing is more critical in impressioning than in any other clinical procedure. This issue will be thoroughly examined in terms of the complexity of the clinical case. While hydrophilicity is important, it is of value only when the intra-oral surfaces can benefit from this property. To be covered will be the means to pre-treat the surfaces to achieve void free impressions; even deeply subgingival. While implant impressions are somewhat similar to crown and bridge impressions, certain unique factors must be considered to achieve a successful result. The unique aspects of implant impressioning will be presented.
