Fracture resistance of maxillary premolars with mod cavities restored with Zirconomer: An in vitro comparative study
Aim: To test the fracture resistance of maxillary premolars with MOD cavities restored with a new Zirconia reinforced Glass Ionomer Cement (Zirconomer) and to compare it with other conventional posterior restorative materials like GIC and Amalgam. Materials and Methodology: Freshly extracted forty intact, non-carious human maxillary premolars were collected and stored in distilled water. The te...
متن کاملEffect of two types of composite fibers on fracture resistance of endodontically treated maxillary premolars: an in vitro study.
AIM The aim of the present study was to evaluate the effect of the use of composite fibers (glass fiber and polyethylene fiber) at the gingival third of mesio-occlusodistal (MOD) cavities on the fracture resistance of endodontically treated premolars. MATERIALS AND METHODS A total of 45 extracted premolars underwent endodontic treatment. MOD cavities, 2.5 ± 0.2 mm thick at the buccal and ling...
متن کاملFracture Resistance of Endodontically Treated Maxillary Premolars Restored by Various Direct Filling Materials: An In Vitro Study
The aim of this study is to compare the effect of various restorative materials on fracture resistance in maxillary premolars. Premolars (n = 64) with no restorations or cracks were selected. MOD cavities were prepared considering the buccolingual width to be equal to half of the intercuspal distance. The specimens were randomly divided into 8 groups, 8 specimens each: group A intact teeth, gro...
متن کاملEffect of Post Material and Length on Fracture Resistance of Endodontically Treated Premolars: An In-Vitro Study
BACKGROUND Endodontically treated teeth with posts are more prone to fracture. Hence, the purpose of this study was to investigate the in-vitro fracture resistance of devitalized teeth and mode of failure restored with posts of different materials and different lengths. MATERIALS AND METHODS Sixty freshly extracted human mandibular premolars were endodontically treated and then restored with ...
متن کاملEffect of marginal design on fracture resistance of IPS e.maxall ceramic restorations: Chamfer versus shoulder finish lines
Background and Aim: One of the problems of all ceramic restorations is their risk of fracture due to occlusal loads. The aim of the present study was to compare the effect of two marginal designs (shoulder and chamfer) on the fracture resistance of IPS-emax all ceramic restorations. Materials and Methods: One extracted maxillary first premolar received chamfer 50' marginal preparation (0.8 m...
