Marginal seal comparisons between resin-bonded Class II porcelain inlays, posterior composite restorations, and
The International Journal of Prosthodontics
|May 1, 1989
Abstract:
The microleakage of indirect porcelain and direct composite resin-bonded inlays was compared with that of posterior composite resin restorations using Class II preparations of extracted molar teeth. The resin-bonded inlay restorations provided a better marginal seal at the cervical restoration/dentin interface than did the composite resin restoration. The efficacy of this marginal seal varied with the particular treatments and materials used. Resin-bonded porcelain inlays had a higher incidence of cervical excess from the composite resin luting agent than did the posterior composite resin restorations.
