Adaptation of threaded dowels to dentin.
Adaptation of threaded dowels to the walls of the canals is minimal in the cervical third and maximal in the apical third. Each of the three types of dowels may cause lateral stresses and possibly fracture. Matched reamers and dowels reduce the danger of fracture. Smaller-diameter dowels maintain less contact with the dentin and avoid weakening the root. The Kurer Anchor system provided a satisfactory combination of nonlateral residual stresses which protected the root from complications.
