This study refers to the problem and summarises the current concepts of treatment concerning orthodontic occlusal movement and prosthetic restoration of subgingivally located roots. Clinical cases are also presented.
The interfacial oxides formed during the oxidation stage of porcelain dental alloys are of primary importance. The purpose of this study was to identify the type of the oxides in three commercial alloys and to evaluate their adherence with the underlying alloy before and after porcelain application. X-ray diffraction analysis revealed the presence of PdO,(More)
