Stress distribution of post-core applications in maxillary central incisors.
The purpose of this study was to evaluate the stress distribution in a maxillary central incisor restored with various post-core applications. The study used a three-dimensional finite element method. The tooth was assumed to be endodontically treated with a porcelain crown. Two different sizes of Flexi-post, Cera-post, and Composipost were compared for 200 N palatal and incisal loads. It was d...
متن کاملComparison of the Fracture Resistance of Endodontically Treated Maxillary Incisors Restored with Six Different Post and Core Systems
Background and Aim: Different methods and materials are available for post and core (P&C) fabrication. We aimed to compare the fracture resistance and failure modes of endodontically treated maxillary central incisors restored with six different P&C systems. Materials and Methods: In this in-vitro study, after endodontic treatment and coronal preparation of 60 maxillary central incisors, six d...
متن کاملEffects of post-core design and ferrule on fracture resistance of endodontically treated maxillary central incisors.
STATEMENT OF PROBLEM Studies concerning the effects of post-core design and ferrule on the fracture resistance of endodontically treated teeth remain controversial. PURPOSE The purpose of this study was to investigate in vitro the effects of post-core design and ferrule on the fracture resistance of root canal treated human maxillary central incisors restored with metal ceramic crowns. MATE...
متن کاملFinite Element Analysis of Maxillary Central Incisors Restored with Various Post-and-core Applications
The purpose of this study was to investigate the effect of rigidity of post core systems on stress distribution by the theoretical technique, finite element stress-analysis method. Three-dimensional finite element models simulating an endodontically treated maxillary central incisor restored with a zirconia ceramic crown were prepared and 1.5 mm ferrule height was provided. Each model contained...
متن کاملPost-traumatic impaction of maxillary incisors: diagnosis and treatment.
AIM To provide clinicians with useful information for immediate diagnosis and management of impacted maxillary incisors due to trauma. METHODS We present a case of post-traumatic impaction of a central right maxillary incisor in a young patient. The treatment plan consisted in the interceptive management (surgical and orthodontic), the valuation of the necessary space to move the impacted too...
