Abstract:
There is currently no standardized method for testing dentures made of dental ceramic materials. This creates problems for comparisons between studies concerning strength in materials and geometry. The geometry of the maxillary first premolar was used for the analysis. The modeled crown has two underlying layers, a thin cement layer closest to the crown that attaches the crown to dentin. Simplifications are made so that dentin geometry is modeled in CAD as a cuboid and the cement layer above follow its geometry. For the actual analysis, a FE-analysis has been made of different loading position

Abstract:
The desire to replace missing teeth with the aim to improve health and quality of life dates back to a thousand years ago. Although research on dental crown designs, materials and techniques has increased in recent years and is expected to grow in the future. In the past few decades, dental crown studies have gained high importance in dentistry due to their functionality, biocompatibility and good mechanical properties. This paper provides a comprehensive review of history and evolution of dental crowns. The goal of this study is to understand the dental crown materials and the differences in

Abstract:
Abstract Metal ceramic restorations have been used in fixed prosthodontics since the 1950s, but the lack of aesthetics, the inclination to use metal-free materials, possible allergic reactions to metals, and the high cost of high noble alloys have increased the use of all-ceramic materials. The ongoing development of ceramic materials led to the introduction of zirconia to fixed prosthodontics over a decade ago. The mechanical properties of zirconia have proven to be excellent, but the clinical outcome of conventional fixed zirconia restorations over the long term is unclear. This retrospectiv

Abstract:
Restoring the masticatory function requires a strong restoration which can withstand the masticatory load and survive other challenging conditions in the oral cavity. Historically, several materials were proposed to restore aesthetic and function of the missing teeth such as ivory, bones or even natural teeth obtained from human donors. Since the 1960s, metal ceramic technology has been a very successful application to replace missing tooth/teeth. However, aesthetic and biocompatibility disadvantages of the metal ceramics encouraged the development of strong and competitive metal-free restorat

Abstract:
Crowns have been used since the 5th century AD to improve both the form and function of teeth in the mouth. A great proportion of the total expenditure on dental care is spent on the provision and replacement of crowns and bridges and the number is increasing every year. A full coverage crown is a restoration placed over a single prepared tooth or it acts as an abutment in a bridge for the restoration of a missing tooth or teeth. Crowns are considered successful only when they meet both the aesthetic and functional requirements of the patient. For these to be met, certain principles for the pr

Purpose: The purpose of this study was to evaluate esthetic posterior stainless steel crowns (EP-SSC) and compare their relative shear strengths.Methods: Sixty EP-SSC were compared. 15 crowns from NuSmile® Primary Crowns, Kinder Krowns, and Dental Innovators 1UP and EC Crowns were studied. The crowns were cemented to a typodont tooth then thermally cycled in water baths to simulate oral conditions. Shear strengths were evaluated by subjecting these crowns to simulated forces of occlusion.Results: The force required to cause shearing of the esthetic facings was statistically significant.

Abstract:
Coroas cerâmicas têm sido amplamente utilizadas, entretanto, problemas relacionados com a fratura destes materiais persistem principalmente nos sistemas ceramocerâmicos na região de molar. As hipóteses nulas testadas foram que o desenho da infraestrutura e o tipo de material não terão efeito significante na resistência à fadiga. Coroas metalocerâmicas e ceramocerâmicas foram fabricadas sobre o preparo de um molar superior, o qual reproduzia a complexa morfologia dos preparos dentários. Quatro grupos foram estabelecidos (n=10 por grupo) baseados no desenho das infraestruturas (padrão ou alterad

Abstract:
A longevidade das coroas cerâmicas depende, entre outros fatores, de sua adaptação ao pilar, bem como da distribuição das tensões nas mesmas. Não há um consenso sobre a melhor adaptação dos copings de zircônia feitos em CAD/CAM em relação aos métodos convencionais, podendo haver uma influência da contração de sinterização sobre esta. O presente estudo avaliou as alterações dimensionais decorrentes do processo de sinterização em três diferentes marcas comerciais de blocos de zircônia, relacionando-as com a adaptação de copings confeccionados por um sistema CAD/CAM, além de avaliar como a adapta

Inicialmente, este projeto investigou o comportamento biomecânico de diferentes coroas monolíticas convencionais sobre dentes e a distribuição de tensões na camada de cimento (Artigo 1). Como objetivo principal, este estudo avaliou o efeito do princípio do mínimo preparo dental no comportamento biomecânico, confiabilidade e translucidez de coroas monolíticas posteriores em cerâmica.

Abstract:
Maxillary sinus pneumatization is a frequently encountered problem in the dental implant rehabilitation of the posterior maxilla. Maxillary sinus augmentation (MSA) using a lateral wall approach is a well-established and commonly utilized surgical technique for overcoming this bone deficiency and allowing implant placement. MSA is still in the refinement process with a large degree of variation in all aspects of the technique including; the surgical protocol, the anatomical site, the choice of material, the site of autogenous bone harvesting, the timing of implant surgery and the use of barrie
