Title Resin-Based Composite Inlays Perform Marginally Better Than Porcelain Inlays
Clinical Question Do Cad/Cam-generated composite(3M Paradigm) inlays perform better clinically than Cad/Cam-generated porcelain(Vita Mark II) inlays?
Clinical Bottom Line At three years, Cad/Cam generated composite inlays (3M Paradigm) perform equally as well as Cad/Cam-generated porcelain (Vita mark II) inlays with better clinical performance in color match to the tooth and fracture resistance. (See Comments on the CAT below)

#1) 16383055Fasbinder/200543 subjects with 1-3 two-three surface carious lesions.Randomized Controlled Trial
Key resultsThere was no significant difference between the composite inlays and porcelain inlays in any clinical criteria except for color match. At three years, 86.5% of the composite restorations placed were ranked Alfa for color match while only 58.8% of porcelain inlays placed ranked Alfa for color match (P<.05).

Comments on
The Evidence
The study design is a randomized controlled trial where all the patients were similar at the start (sound occlusion, vital teeth, low caries risk). There was greater than a 90% completion rate and all subjects received 2-3 surface restorations. There was adequate follow-up and compliance for up to three years post-treatment. The study was double-blind and recall bias is unlikely with no competing interests.
Applicability In a patient with the need for a 2-3 surface posterior inlay, the use of either porcelain or composite with Cad/Cam-generated design will provide a functional, stable, durable, and esthetic restoration. The composite restorations will maintain better color match than the porcelain.
