Preparation Design and Considerations for Direct Posterior Composite Inlay/Onlay Restorations
Jason Fligor, DDS
In order to ensure a functional, aesthetic, and long-lasting porcelain result, clinicians need to anticipate the strengths and limits of the restorative material, as well as the specific requisites of the presented case. As flaws in preparation design can have significant and detrimental effects on the final result, clinical comprehension of the dimensions and limitations during this step is of the utmost importance. This podcast discusses a case presentation in which porcelain restorations were placed for two adjacent teeth. Although the clinician anticipated placing inlay or onlay restorations, the degree of decay and the location of hairline fractures would necessitate prophylactic removal of a weakened or undermined cusp.

This podcast presents the factors that must be addressed when considering the type of tooth reduction required for contemporary inlay/onlay restoration. Upon completing this podcast, the listener should:
- Understand the role of correct preparation design on the success of a posterior composite restoration.
- Recognize the preparation sequence associated with successful inlay/onlay restoration in the posterior region.
