Submargination of a resin luting cement--a clinical case report

The purpose of this case report was to examine the marginal integrity of an indirect inlay and an onlay luted with resin luting cement over a four year period. A technique to seal the occlusal margins of the inlay restoration was reported. Over time, the occlusal margins of the inlay were noticeably submarginated due to wear degradation of the resin inlay cement. The onlay margins were less affected by wear. Clinical techniques to overcome submargination problems were discussed.
