Restoration of badly broken, endodontically treated posterior teeth

Abstract

It is generally agreed that the successful treatment of a badly broken tooth with pulpal disease depends not only on good endodontic therapy, but also on good prosthetic reconstruction of the tooth after the endodontic therapy is complete. Often, we come across an endodontically treated tooth with little or no clinical crown in routine clinical cases. In such cases, additional retention and support of the restoration are difficult to achieve. Two case reports are discussed here where structurally compromised, endodontically treated, posterior teeth were restored using the Richmond crown in the first case, and by the use of two nonparallel cast posts in the second case.

“…Such situations further get complicated when there is deep bite with no/very less overjet in anterior teeth; as oblique forces are maximum and core reduction should be adequate to provide indicated thickness for ceramic/metal ceramic crown to achieve desirable esthetics. mishra et al 8 Richmond crown is very much indicated in situations with very less incisal clearance to accommodate core+cement+crown thickness.…”

“…The main purpose of a “post” is to retain a core in a tooth that has lost its crown structure extensively. [ 4 ] The main application of Richmond crown is that it can be used in the badly broken single tooth where the remaining height of the crown is very low. The advantages of using this design include custom fitting to the root structure, low or no stress generation at the cervical margin, and high strength when the “post and core” are two separate entities.…”
