Use of onlay-type composite resin inlays in structurally involved molars

Abstract

The composite resin inlays are a low cost alternative which seeks improvements to
the direct filling methods meet the challenges of the marginal adaptation, location
of proximal contacts, allows us to improve the restoration dental anatomy and
overcome the phenomenon of contraction at large sections of material polymerized
outside the dental cavity. The objective of this article was to show the use of the
composite with indirect technique how an alternative to easy handle and significant
clinical results with the structural involvement of molars. The article reports two
cases of composite resin inlay onlay in two permanent molars structurally affected,
one endodontically treated. The collection of models is performed by the arch
alginate impression of the teeth selected, making silicone light casting the prepared
tooth and the rest in type III dental stone to obtain a die of work on drawing up the
inlay in incremental technique. The cementation process oral cavity is carried out
with dual cure resin cement. To control at six months for signs of a leak or marginal
jet we used air-dried syringe, explorer and periapical X-Ray. The clinical
examination and radiographic analysis revealed a good performance of the
restorations in the absence of mismatch or marginal pigmentation. In conclusions
the use of the composite inlays in molars with structural involvement with indirect
technique is an alternative to easy handle and significant clinical results.
