Restoration integrity, but not material or cementation strategy determined secondary caries lesions next to indirect restorations in vitro

Extended dental hard tissue defects resulting from large carious lesions or tooth fractures are frequently restored using indirect restorations like full and partial crowns or on- and overlays. In Germany, for example, over 2 million such restorations are placed each year under the tenets of the statutory insurance, generating costs of hundreds of million Euro annually [1]. For partial indirect restorations, metal (mainly gold) has traditionally been used (partial gold restorations, PG). Within the last three decades, partial ceramic restorations (PC) have gained popularity.
