Marginale Adaptation von stopfbaren Kompositen und Ormoceren in Klasse-II-Kavitäten

Because of increasing aesthetic demands and the discussion about amalgam, composites are used more and more to restore posterior teeth. Packable composites and ormocers are discussed as better alternatives for amalgam as stress-bearing posterior restorations when compared to traditional hybrid composites. Aim of the study was to determine adhesive properties (quantitative and qualitative) by analysis with the SEM and by dye penetration of several packable materials in control by a traditional hybrid composite. Statistical analysis of the results showed significant differences among the tested materials. Surefil and Admira revealed the best adhesion to enamel and dentin, while Definite and Solitaire demonstrated inferior results. The control group Tetric ceram revealed for all measured data values in the middle of the range of the tested materials. The packable composites / ormocers comprise a rather inhomogeneous class of materials. The measured values of adhesion scatter in wide range. The use of these materials in stress – bearing posterior cavities cannot be recommended in general. Instead of amalgam substitutes they should be taken as amalgam alternatives that still must be improved and assert themselves in long - term clinical studies.
