“Fracture Resistance of Endodontically Treated Maxillary Incisors Restored by Two Designed Endocrowns Using Two Materials”

Abstract

The best way to restore endodontically treated teeth is still controversy. There are also many newly introduced ceramic dental materials which can be used for restoration of endodontically treated teeth. Conventional and modified endocrowns were used to be compared to conventional fiber post, core and full coverage crown restoration. All specimens were restored using lithium disilicate (e.max) and Vita Enamic CAD blocks. Thirty maxillary incisors were selected without any fractures or carious lesions with approximate similarity in shape, size and morphology. All teeth were treated endodontically and divided into three major groups according to restoration designs. Samples were divided into 3 groups according to the restoration design as follow: 1. Group (C): 10 endodontically-treated maxillary incisors restored by conventional endocrowns. 2. Group (M): 10 endodontically-treated maxillary incisors restored by modified endocrowns. 3. Group (F): 10 endodontically-treated maxillary incisors restored by fiber posts, core and full coverage crowns.
