Composites are resin based tooth colored filling materials which can be bonded to the tooth. Earlier very few materials were available, when one has to go for the filling. It used to be either silver or gold restorations. These materials have very unaesthetic looks, especially if the front tooth has to be filled. When one has to choose the restorative material, number of factors are taken into consideration. Like
Types of composite filling- on the bases of how they can be used the composite fillings are divided into two types
Indirect type- this is used for making composite inlays or onlays and the composite veneers. In this is first of all impressions are taken to make the mold of the tooth cavity in which filling has to be done. It is fabricated outside the mouth in the lab and on the next appointment it is fitted in the patient’s mouth. This is comparatively expensive ad time consuming as the patient has to come minimum for two times. But strength wise the properties are better than the direct technique. Normally inlays and onlays are made when the cavity size is big.
Direct type- in this the filling of composite is done directly in the patient’s mouth. This is done in the single visit. It is indicated in closing the gaps (distema) in the front teeth.
