What are the Complications of Stainless Steel Crown?

A semi-permanent restorations for the young permanent and primary teeth were done using stainless steel crowns. But, these restorations also have complications. The complications of stainless steel crown are discussed briefly below in this article. Let us examine them.

Complications of stainless steel crown

The following are the common complications that can arise with stainless steel crown preparation are:

  • Interproximal ledge:

    • A ledge will be produced instead of a shoulder free interproximal slice, if the amgulation of the tapered fissure bur is incorrect.
    • Failure to remove this ledge will result in difficulty in seating the crown.
    • When the adjacent tooth is partially erupted and the contact area is poorly established, the interproximal slice is difficult to prepare.
    • To clear the contact are, extensive subgingival tooth reduction is required which may result in formation of a ledge or damaging the erupting tooth.
    • In such a case, it may be wise to delay crowing until contact areas are properly established.
  • Crown tilt:

    • Complete lingual or buccal wall may be destructed by caries or improper use of cutting instrument.
    • This may result in finished crown tilting toward the deficient side.
    • Placement of restoration prior to crowing provides a support to prevent crown tilt, the alloy acting as a core.
    • The clinical significant of crown tilting is minimal unless it occurs on young permanent molars where supra-eruption of the opponent tooth may occur.
  • Poor margins:

    • When the crown is poorly adapted, its marginal integrity is reduced.
    • Recurrent caries may occur around open margins.
    • Chances of plaque retention and subsequent gingivitis increases with marginal discrepancy.
    • The tolerant potential of young periodontal ligament tissues is very high to an extreme amount of zinc phosphate cement pushed into lingual sulcus during the cementation procedure.
    • The foreign body was incorporated without any signs of gingivitis and discomfort to the patient.
  • Inhalation or ingestion of crown:

    • To prevent such mishaps, the rubber dam should remain in place until cementation.
    • It prevents accidental swallowing or aspiration of a crown.
    • Sometimes sudden movement may result in inhalation or ingestion of the crown.
    • If this occurs, attempt can be made to remove the crown by holding the child upside down as soon as possible.
    • If this is unsuccessful, medical referral should be done for an immediate chest X-ray.
    • If the crow is in bronchi or lung, medical consultation will probably result in an attempt to remove it by bronchoscopy.
    • The presence of cough reflex in the conscious child will reduce the chances of inhalation and ingestion of the crown is more likely.
    • Ingestion is of less consequence as the crown will usually pass uneventfully through the alimentary tract within 5-10 days.
    • But it should be diagnosed by absence of the crown on a chest radiography.

Some of the other of stainless steel crown that were noticed within the first day after the stainless steel crown due to general anesthesia include the following:

  • Younger kids had diarrhea
  • Older children were suffering with vomiting

But, more severe and moderate complaints were reported due to this stainless steel crown restoration procedure.

The above article discusses briefly about the complications of stainless steel crown. But, the stainless steel crwons are used to restore the back teeth which are badly weakened due to large fillings, pulpotomies or decay. The stainless steel crown covers the damaged tooth structure and also strengthens the tooth to prevent it from further breakdown. Though the crown is visibly apparent when the patient mouth is open, but most of them are proud to have their special tooth.
