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

  • The tooth which has to be filled e.g. if front tooth has to be filled we only consider the tooth color materials which give esthetic looks so in that case composite is the option.
  • Type of cavity i.e. the cavity is big or small.
  • Properties of the material like whether the particular material is indicated for the specific cavity
  • Cost of the filling material –some materials are expensive and some are cheap. Silver amalgam filling is cheaper than the composite filling.

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.

Composites are available in many shades so according to the color of the tooth shade is selected to give esthetic results. Composites are resins which have light sensitive agent in t. this can be cured with the light to make it hard. Before putting the resin in the cavity the area is treated with a agent that is called as the etching process. After that the bond is applied which is cured by the light above this the composite is placed and is cured with light.

  • LEE SOREY, the only disadvantage with resin based materials is that they donot completely polymerize so the unreacted monomers can leach out of the resin matrices. The adverse reactions (though rare) to resin based filling include skin or mucosal reactions termed as lichenoid reactions. The reaction subsides upon the removal of filling. Direct contact of resin with skin can lead to dermatitis or eczema.

  • are there any reactions (allergies)to the resin based filling
