INTRODUCTION In cases where the patient experiences trauma, the teeth may be fractured or a bone segment could be fractured causing misplaced teeth. Ceramic veneer restorations may be a solution for re-establishing the ideal position. The treatment of misplaced dental arch segment is presented and treatment options are discussed. CASE PRESENTATION A 30-years-old female Turkish patient had a h...

INTRODUCTION This article presents a 6-month case report and an in vitro evaluation of the performance of the new self-etching glass-ceramic monobond etch and prime (MEP) when applied in a lithium disilicate (LD). The MEP contains in the same bottle, along with acid conditioner and silanes. This simplifies the bonding procedures by reducing not only the number of steps, but also the working tim...

STATEMENT OF PROBLEM The color stainability of recently introduced computer-assisted design/computer-assisted manufacturing (CAD/CAM) hybrid ceramic and resin nanoceramic is unknown. PURPOSE The purpose of this in vitro study was to compare the effect of coffee staining on the color of 3 different CAD/CAM restorative materials and a nanocomposite resin. MATERIAL AND METHODS Specimens from a...

The purpose of this study was to determine the effect of cavity depth, ceramic thickness, and resin bases with different elastic modulus on von Mises stress patterns of ceramic inlays. Tridimensional geometric models were developed with SolidWorks image software. The differences between the models were: depth of pulpal wall, ceramic thickness, and presence of composite bases with different thic...

STATEMENT OF PROBLEM Production of a ceramic dental restoration that matches a target shade is dependent on porcelain thickness. Even when adequate porcelain thickness exists, clinical shade matches are difficult to achieve. PURPOSE This study predicted the thickness of dentin porcelain required to obtain a clinical shade match (</=3 DeltaE units) for a variety of dental porcelain systems and...

introduction: the purpose of the presented study was to evaluate the effect of zirconia thickness on the tensile stress of zirconia based all-ceramic restorations. methods: twenty zirconia disks with 10mm diameter were prepared in two groups using cad/cam system. the thickness of zirconia was 0.5mm in first group and 0.3mm in second group. after sintering, 0.4mm glass ceramic porcelain was appl...

STATEMENT OF PROBLEM In some clinical situations, the length of either a prepared tooth or an implant abutment is shorter than ideal, and the thickness of a porcelain crown must be increased. Thickness of the coping and the veneering porcelain should be considered to prevent mechanical failure of the crown. PURPOSE The purpose of this study was to investigate the influence of veneering porcel...

abstract : alumina (al 2 o 3 ) is one of the most practical ceramics used in making ceramic-metal armours. to improve the properties of alumina, some other materials are added to it. in this paper, sic material as nano powder is added to alumina, and four armour samples of this new ceramic with different volume fractions (v.f. ) including 0%, 5%, 10% and 15% of sic particles are made. then, the...

Significant progress has been achieved in ceramics since the late 1990s1-4). In particular, new technological innovations such as heat-pressed5,6), injection-molded7), slip-cast8), and glass-infiltrated ceramics9-11) have widened the use of ceramics in prosthetic and operative dentistry. However, properties such as brittleness limit their use in applications such as fixed partial dentures. Sinc...
