A longitudinal complicated crown-root fracture of an unerupted permanent incisor following trauma to primary teeth is reported. The development of the affected permanent tooth was not disturbed during a follow-up period of six years. Traumatic injuries to primary teeth can be transmitted to the permanent dentition because of the close relationship between the apices of primary teeth and the dev...

In the present case reports, it was aimed to present the treatment of 2 non-complicated crown fracture trauma cases using reattachment technique. In the first case 12-years-old patient was applied to our clinic due to crown fracture. In the clinic examination the tooth’s mobility was within the normal limits and tooth was not tender to percussion. There was also cold-sensitivity due to the expo...

BACKGROUND This article describes the management of a complicated crown root fracture. CASE REPORT A young patient presented with a crown root fracture of the maxillary left central incisor with an oblique subgingival fracture line. A multidisciplinary treatment approach including endodontic treatment, orthodontic extrusion, surgical extraction and intra-alveolar repositioning was used to gai...

This case report describes the management of an oblique crown-root fracture of maxillary left central incisor. After removal of the fractured fragment, endodontic treatment, the remaining tooth was provisionally restored. The tooth was then orthodontically extruded by 3 mm to raise the defect supraginigivally. Periondonal fibres were cut with a surgical blade. A metallic screw type post was ins...

Young patients are often frequently involved in traumatic dental injuries. The most common type fracture in permanent anterior teeth is a crown fracture. Direct restorative procedures using composite and fiber posts can be an esthetic and conservative approach in the case of extended fracture of an anterior root-filled tooth with little remaining coronal tooth structure. Currently, prefabricate...

The purpose of this study is to evaluate the fitting accuracy and fracture resistance of crowns using a hybrid zirconia frame made of both porous and dense zirconia. Commercial semi-sintered zirconia, sintered dense zirconia and sintered hybrid zirconia were used. Sintered zirconia was milled using the CAD/CAM system, and semi-sintered zirconia was milled and sintered to fabricate molar crown f...

This study investigated the effect of fiber reinforced composite resin (FRC) post lengths, ferrule, and full coverage metal crown on fracture resistance of endodontically treated teeth (ETT) using an experimental FRC post with the similar elastic modulus of dentin (11.5 GPa). ETT was restored according to 1 of 7 combinations of FRC post length (10, 5, 2.5, 0 mm), ferrule (0, 2 mm), and with/wit...

STATEMENT OF PROBLEM Unresolved controversy exists concerning the remaining coronal tooth structure of anterior endodontically treated teeth and the best treatment option for restoring them. PURPOSE The purpose of this study was to evaluate the effect of post, core, crown type, and ferrule presence on the deformation, fracture resistance, and fracture mode of endodontically treated bovine inc...
