The marginal fit of lithium disilicate crowns: Press vs. CAD/CAM

Abstract: This study aimed to compare the vertical marginal gap of teeth restored with lithium disilicate crowns fabricated using CAD/CAM or by pressed ceramic approach. Twenty mandibular third molar teeth were collected after surgical extractions and prepared to receive full veneer crowns. Teeth were op...

Reliability of light microscopy and a computer-assisted replica measurement technique for evaluating the fit of dental copings

J. appl. oral sci; 26 (), 2018
Abstract The aim of this in vitro study was to assess the reliability of two measurement systems for evaluating the marginal and internal fit of dental copings. Material and Methods: Sixteen CAD/CAM titanium copings were produced for a prepared maxillary canine. To modify the CAD surface model using dif...

Avaliaçäo "in vitro" da qualidade do vedamento marginal cérvico-apical de alguns agentes cimentantes utilizados na fixaçäo de um retentor intra-radicular pré-fabricado (CYTCO)

Neste estudo avaliou-se a capacidade de vedar o canal radicular com o retentor intra-radicular Cytco(Mailleffer) fixado com cimentos de óxido fosfato de zinco, ionômero de vidro ou policarboxilato. Observou-se que nenhum dos cimentos testatos foram capazes de vedar o canal radicular hermética e tridim...
