Abstract

The first composites in indirect technique (Mörmann 1982, Touati 1983), made using microfilled resins, were not a great success because of their mediocre properties. On the other hand, in view of the good results obtained with the feldspar ceramics used for the facets, these were introduced for later inlays-onlays posterior.However, the number of fractures of the restorations initiated a return of the practitioners towards the composite in view of the constant evolutions of the material with time.

Composites have evolved a lot in the last decades (from micro-filled composite to nanohybrid), not only in terms of mechanical properties (decrease of polymerization stress ...) but also in their ease of work (choice of color, injectable materials, polishing ...). In addition, the realization of the contact point is much easier with the current material available (metal matrices fine and pregalbées, spacer ring ...). Therefore, nowadays, one can expect a longevity of at least 10 years for a direct composite inserted in a small cavity.
