Impact of a Core Ferrule Design on Fracture Resistance of Teeth Restored with Cast Post and Core

Abstract: Objectives. To investigate the influence of a contra bevel on the fracture resistance of teeth restored with cast post and core. Materials and Methods. Sixty plastic analogues of an upper incisor were endodontically treated and prepared with 6° internal taper and 2 mm of ferrule in order to receive a cast post and core. The prepared samples were divided into two groups (n = 30); the first group serves as control while the second group was prepared with an external 30° bevel on the buccal and lingual walls.

“…Romeed and Dunne [13] compared the stress distribution between metallic posts or glass fiber posts and the dentin walls of root canals and found a significant increase in root tensions in the group restored with fiber posts, which lead to the conclusion that the modulus of elasticity of the intraradicular post is inversely proportional to the stress transmitted to the root, in agreement with other studies [6,9]. It is important to note that the stress distribution in the root dentin is the main factor leading to restoration failure, once it can generate root fractures, cement-post debonding of the dentin walls, and post mobility, which must be taken into consideration by the clinician during the proper case planning [16].…”

“…The absence of coronal walls was described as the worst scenario for tooth rehabilitation [15]. Cast posts and cores have been considered the method of choice in these cases [16]. The clinical survival of posts has shown to be improved when they are chemically bonded to the dentin, as it promotes greater retention and attenuates the weakening of the dental structure [2].…”

“…Post restoration choice and ferrule affect the prognosis of endodontically treated teeth 1,2 . Although the use of fiber reinforced composite posts is increasing in contemporary dentistry 2 , cast post and cores (CPCs) remain one of the most used post type 3,4 .…”
