Objective: The applications of single-structure fiber-reinforced composite (FRC) in restorative dentistry have not been well reported. This study aimed to clarify the static mechanical properties of anterior crown restorations prepared using two types of single-structure FRC. Materials and methods: An experimental crown restoration was designed for an upper anterior incisor. The restorations we...

STATEMENT OF PROBLEM Contemporary pressable and computer-aided design/manufacturing (CAD/CAM) ceramics exhibit good mechanical and esthetic properties. Their wear resistance compared with human enamel and traditional gold based alloys needs to be better investigated. PURPOSE The purpose of this in vitro study was to compare the 2-body wear resistance of human enamel, gold alloy, and 5 differe...

This Paper presents a 12 bit ADC is designed for the implementation of pipeline ADC. To design this ADC we used TIQ comparator that reduced the power consumption and area. The sample and hold circuit have high Sampling rate. This Design is implemented and verified on the LT spice switcher CAD-III in 0.18μm Technology.

Background: The purpose of this study was to investigate the effect of etching time using 9% hydrofluoric acid on Fracture Load (FL) and surface properties, such as Surface Free Energy (SFE) and Surface Roughness (SR) of three CAD/CAM glass-ceramics. Methods: Following glass-ceramics were investigated: EMP (IPS Empress CAD), KLE (KLEMA CAD/CAM glass-ceramic) and EMC (IPS e.max CAD). For FL, sta...

Objective: The current study aimed to evaluate the effect of diode laser irradiation (980 nm) and warm air drying(50°C) on shear bond strength between Lithium di-silicate (IPS e.max; Ivoclar) human dentin using both(Etch & Rinse) adhesive, Adper™ Single Bond 2 (3M ESPE) (Self-etch) UniversalTM(3M before adhesive polymerization. Material Methods: 54 sound lower molars were sectioned toobtain...

Amaçlar: Bu çalışmanın amacı, tribokimyasal yüzey işleminin (Tbc) güncel CAD/CAM post materyalleri ile kök kanal dentini arasındaki itme bağlantı dayanımına (İBD) etkisinin değerlendirilmesidir. Gereçler ve Yöntemler: Yeni çekilmiş sağlam 52 adet insan maksiller santral kesici dişleri seçildi endodontik olarak tedavi edildi. Dişler, kullanılan materyaline göre rastgele 7 gruba ayrıldı: Kompozit...

Aim The aim of the present work was to compare the elastic properties and internal structure of 4 different CAD/CAM chairside materials, by the method of Scanning Impulse Acoustic Microscopy (SIAM). Methods Four chairside CAD/CAM materials with different structures from hybrid ceramic (VITA Enamic, VITA Zahnfabrik), feldspatic ceramic (VITABlocs Mark II, VITA Zahnfabrik), leucite glass-cerami...
