Kama lateraller, dental anomalilerle ilişkili olabilen, sıklıkla maksiller dişlerde rastlanan, normalden küçük, silindirik, sivri şekillere sahip olabilen dişlerdir. Tedavisinde seramik veya kompozit veneer restorasyonlar kullanılabilir. Seramik doğal diş dokusunun daha fazla kaybına neden olması, maliyetli olması ve tamirinin zor nedeniyle, kama lateral tedavisinde ilk seçenek olarak tavsiye e...

STATEMENT OF PROBLEM Bonded porcelain veneers are widely used esthetic restorations. High success and survival rates have been reported, but failures do occur. Fractures are the commonest failure mode. Minimally invasive or thin veneers have gained popularity. Increased enamel and porcelain thickness improve the strength of veneers bonded to enamel, but less is known about dentin or mixed subst...

OBJECTIVES The primary aim of this research was to investigate the wear behavior and wear mechanism of five different veneering porcelains. METHODS Five kinds of veneering porcelains were selected in this research. The surface microhardness of all the samples was measured with a microhardness tester. Wear tests were performed on a ball-on-flat PLINT fretting wear machine, with lubrication of ...

STATEMENT OF THE PROBLEM The success of metal- ceramic- restorations (MCR) depends on the presence of strong bond between porcelain and metal substructure. PURPOSE The purpose of this study was to evaluate the effect of hot pressing technique on the bond strength of a metal-porcelain composite in comparison to layering technique. MATERIALS AND METHOD Thirty Nickel-Chromium specimens were pr...

Nondestructive evaluation of materials, the science of identifying the physical and mechanical properties of materials without altering their end-use capabilities, is valuable in defining relationships between properties and performance of materials. Nondestructive evaluation techniques using these relationships have current industrial applications. They are used for machine stress rating of lu...

Introduction: To achieve acceptable clinical performance, a ceramic veneer must be bonded to enamel by well-polymerized resin cement. Among different factors, thickness and translucency of the ceramic may affect the resin cement polymerization. Thus, the current study evaluated the effect of the thickness and translucency of lithium disilicate ceramic on light-cured resin cement bond strength t...

The porcelain veneer is very esthetic and conservative treatment modality for many indications. success of depends much on the method fabrication most importantly case selection. An attractive appearance with has shown to increase people’s self-confidence, personal relationship, even in his or her career. Hence veneer, it possible create amazing results yet retain considerable solid tooth struc...
