Indirect composite inlays, onlays and partial crowns in a follow-up study

Written by Pongrácz Antal, Pongrácz István-Mátyás, Vitos Gábor

New indirect (for laboratory made) composite materials are remarkable due to their high concentration of inorganic fillers (ex. Estenia, Kuraray), and their improved polimerization rate (ex. BelleGlass-Kerr). 32 inlays, onlays and partial crowns made of Estenia between 2003-2005 were examined clinically, in a 6-months recall program. The examination included: inspection with magnifying loupe and intraoral camera, checking the cementation line with the tip of a new explorer, and colouring with a plaque-disclosing solution. The occlusal wearing was appreciated with an 8μm occlusal indicator folio. It has to be mentioned, that every cavity was blocked out with HEMA containing GIC, Fuji II LC at the time of inlay fabrication. The same material was used at the part of the cavities that is near to the gums. The fixation was completed with Fuji Plus (GIC with HEMA), Panavia F2 and Maxcem (composite luting). In 4 years not a single inlay has been lost, in 3 cases fissures have been observed on the occlusal lines of cementation, and in other 4 concave surfaces on GIC after 2 years.
