This clinical report has the objective describing a procedure involving digital placement porcelain laminate veneer restorations. The included dental facial analyzes. curve was drawn ruler used to delimitate spaces each tooth. An appro...

Dental arktaki iki daimi dişin kendi aralarında yerlerinin değişmesi sonucu gelişen alışılmadık ektopik erüpsiyon türü ‘’diş transpozisyonu’’ olarak tanımlanmaktadır. Çok sık görülmeyen bu diş anomalisi en fazla üst çene kanin dişleri tutmaktadır. Üst ön bölge dişlerde şekil ve görünüm bozukluğuna sebep olan durum, estetik kaygılarla hekimlerine başvuran hastalarda tedavisi zor anomalilerinden ...

PURPOSE The aim of this clinical retrospective study was to evaluate the clinical quality, success rate, and estimated survival rate of anterior veneers made of silicate glass-ceramic in a long-term analysis of up to 20 years. MATERIALS AND METHODS Anterior teeth in the maxillae and mandibles of 84 patients (38 men, 46 women) were restored with 318 porcelain veneer restorations between 1987 a...

compare the effect of different ceramic thicknesses on degree of conversion (dc) of 3 light-cured resin cements. methods: in this experimental in-vitro study, the degree of conversion of three light-cured resin cements, variolink veneer (ivoclar, liechtenstein), relyx veneer (3m espe, usa) and choice2 (bisco, usa) were evaluated beneath feldespatic ceramic discs (vita vmk master) with a same sh...

Using variational mechanics we present mathematical bounds on the effective modulus of a crossply laminate containing microcracks in the 90◦ plies. An average of the two bounds provides an effectively exact solution to the modulus reduction problem. The problem of predicting microcracking is reduced to finding the energy release rate for formation of a complete microcrack. From the bounds on ef...

PURPOSE Porcelain chipping has been one of the main problems of porcelain-fused-to-zirconia restorations. This study evaluates the bond strengths of layered, pressed, and adhesively bonded porcelain to yttria-stabilized zirconia substrates that have undergone traditional preparation or gas-phase fluorination. MATERIALS AND METHODS A three-point bending test was used to evaluate the bond stren...

STATEMENT OF PROBLEM Specific contributions of the core and the veneer thickness on the appearance of layered disk specimens are not well characterized. PURPOSE This study examined the effect of varying core and veneer thickness on the color parameters of layered disk specimens made of 2 ceramic systems. MATERIAL AND METHODS Disk specimens 16 mm in diameter with core/veneer thickness (mm) o...

Fast-growing tree species are important due to their short growth time before they are harvested. Both the Poplar and Eucalyptus species are fast-growing trees. These two species have been cultivated in many parts of the world, and they are used in several ways, including in the pulp and paper industry, as wood-based panels, and as structural composite lumber. In this study, laminated veneer lu...

Changbai larch (Larix olgensis Henry) is one of the main plantation species in the northern part of China, but so far its utilization has been limited to solid wood, pulping, and paper products. As part of a national initiative, the objective of this work was to develop a good understanding concerning how stand management practices affect larch wood and veneer properties. To cope with the varia...
