Composite resin strip crowns


Composite is the material of choice for the restoration of primary anterior teeth. An anterior strip crowns with composite resin provides an aesthetic and durable restoration.

Method:

  1. Local anaesthesia and rubber-dam isolation should be used if possible. Alterna- tively, because of age and poor cooperation of younger children, the restorative work may be completed under general anaesthesia.
  2. Select the correct celluloid crown form depending on the mesiodistal width of the teeth.
  3. Remove the caries using a slow-speed round bur.
  4. Using a high-speed tapered diamond or tungsten carbide bur, reduce the incisal
    height by around 2 mm, prepare interproximal slices and place a labial groove at
    the level of gingival and middle thirds of the crown.
  5. Protect the exposed dentine with a glass ionomer lining cement.
  6. Trim the crown form and make two holes in the incisal corners by piercing with
    a sharp explorer.
  7. Etch the enamel for 20 seconds, and wash and dry.
  8. Apply a thin layer of bonding resin and cure for 20 seconds, ensuring all surfaces
    are covered equally.
  9. Fill the crown form with the appropriate shade of composite and seat with gentle,
    even pressure, allowing the excess to exit freely. The use of small wedges may be
    helpful in avoiding interproximal excess.
  10. Light cure each aspect (labially, incisally and palatally) equally.
  11. Remove the celluloid crown gently, and adjust the form and finish with either composite finishing burs or abrasive discs.
  12. Check the occlusion after removing the rubber dam.
