Restoration of endodontically treated teeth/Build-ups, posts & pins

By Dr.Swathi Pai on Thursday 1 May 2008 with 0 comments



Factors to consider when deciding to restore a tooth with a core build-up

  • Extent of the carious involvement.
  • Restoration/remaining tooth structure..
  • Success of endodontic treatment.
  • Periodontal health status.
  • Occlusion/function requirements.
  • To resist fracture restorative techniques.
  • Should conserve as much dentin as possible.
  • Provide cuspal protection.

''Reagan concluded that a properly completed amalgam restoration with cuspal coverage has the same.''

Resistance to fracture as an unrestored tooth

  • Composite and glass ionomer lack the physical and mechanical properties necessary to function as cusp coverage restorations and load bearing restorations in posterior teeth.
  • Excellent results have been obtained in using composite to restore root canal treated teeth with minimal access preparation and most coronal tooth structure remaining.
  • Cuspal coverage restorations of endodontically treated posterior teeth can be either a core material followed by a casting; or an amalgam core combination amalgam crown.
  • Adequate retention can be achieved from the pulp chamber alone if its height is 4mm or greater.
  • Condensing amalgam into canals, slots, amalgapins, and boxes improves retention.
  • Self threaded pins are an option to increase retention but have inherent risks of crazing and cracking of the dentin or perforation into the PDL.
  • Premolar teeth require post retention more often due to the smaller pulp chamber and dentin available for other internal retentive features.
