The restoration of endodontically treated teeth is one of the most important factors of the
endodontic treatment success. Due to the potential of currently available restorative materials, the
monoblock concept has been introduced for the restoration of endodontically treated teeth using prefabricated
fiber post. The attempt of this concept is to achieve mechanically homogeneous unit of root
dentin and restorative materials by using materials that are able to bond mutually and strongly to the
dentin and have the modulus of elasticity that is similar to that of the dentin. When the load is applied
on the teeth, the material together with dentin will flex leading to the homogeneous stress distribution.
This review demonstrates the monoblock concept in endodontically treated teeth in terms of definition,
classification, factors inducing monoblock, and the limitation and problems occurring with this concept.
