In this module students will apply what they have learned about engineering and biomechanics from the previous module towards how to prepare & design bonded ceramics. This module will build on the previous module and add further knowledge and evidence in how to design ceramic restorations to be more fracture resistant, function more harmonious with the natural tooth, and how to avoid catastrophic failures both biologically and structurally. Overlays, Onlays, & Inlays will be discussed in terms of design, pro's & con's, and indications/recommendations for use.
