--When chipping or fracture of a ceramic restoration occurs in a clinical practice, the clinician must decide whether to replace or repair the prosthesis.  However, valuable information may be obtained by making an impression of the fracture surface and working with a materials scientist who can assist in determining the likely cause of fracture.  This session will provide an overview of fractography and the techniques that are required of both clinician and scientist to perform a reliable failure analysis of these clinical cases.
Attendees will be able to:
1. Identify the purpose of descriptive fractography for clinically failed restorations.
2. Describe the recommended procedure and conditions for making an impression of a fractured surface.
3. Identify the types of information that may can be obtained from failure analysis.

Dental ceramic restorations: Clinical failure analysis using descriptive fractography

Dental ceramic restorations: Clinical failure analysis using descriptive fractography
This is intended for materials scientists, dental lab technicians, and faculty who have experience with fractography and microscopy of fractured clinical restorations. 
--All-ceramic restorations are being increasingly used for posterior teeth-a zone in which the restorations are subjected to higher masticatory loads than on anterior teeth. Consequently, an increased frequency of veneer ceramic chipping or through-the-core-thickness fractures of posterior crowns may be expected. Understanding the reasons for fracture is of key importance to the dental community. To this end, the analysis of clinical failures will be described using fractographic techniques.  This comprises the fracture surface analysis of failed ceramic restorations using a stereomicroscope as well as the SEM in order to identify markings that are indicators of the direction of crack propagation. Mapping of these crack features of the failed component provide evidence of the failure initiation site and what might be done to improve the lifetime of these restorations. 
Attendees will be able to:
1. Identify basic terms and principles of descriptive fractography for clinically failed restorations.
2. Recognize classic fractographic features on different ceramic materials.
3. Improve the anatomical design of CAD-CAM ceramic framework and veneering ceramic based on the results obtained from the failure analysis.
