  • Direct Filling/Restoration
  • Indirect filling /Restoration

DIRECT RESTORATION :

Direct Restoration done with (1) Silver filling, (2) Cast gold filling, (3) Glass ionomer filling, and (4) Composite Resin filling.

1. Silver filling

Also known as amalgam filling.

Pros :

  • It has high strength against chewing force.
  • It has greatest durability among all dental filling material.
  • It may be less expensive than others.

Cons :

  • Silver filling is unesthetic as it doesn’t match the tooth color.
  • While preparing cavity, removes healthy tooth structure also, to make a enough space for mechanical bond of amalgam.
  • Amalgam filling sometime create a greyish hue surrounding tooth structure.
  • In some people, there is allergic reaction of amalgam restoration due to mercury present in the amalgam.

2. Cast gold filling

Pros :

  • Cast gold filling has greatest strength and durability as compare to other dental filling material.

  • Newest generation of Glass ionomer cement has the longest durability and strength when placed in appropriate areas as compared to composite.

Cons :

  • Glass ionomer cement has a shorter durability as compared to amalgam and composite restorative material.
  • It has a weaker strength compared to other restorative materials, so prone to quick wear and tear.
  • Glass ionomer doesn’t have shade options so it’s not perfectly tooth-coloured restorative material as compared to other tooth-coloured restorative material.

4. Composite

Composite is a tooth coloured, highly aesthetic filling material.

Pros :

  • Composite filling material requires minimal tooth preparation, as the decayed parts of a tooth should be removed as compared to amalgam, it requires larger cavity preparation for a mechanical bond.
  • Composite filling micromechanically bond to the tooth surface, provide greatest retention.
  • The composite filling material is a more versatile material, it can be used to repair, chipped, broken, or fractured teeth.
  • Composite material is available in various shades to be closely matched with the shade of existing teeth.

In the second appointment, the temporary filling is removed, and check the permanent restoration, if it fits accurately, it fits permanently with dental cement.
