Misfit and microleakage of implant-supported crown copings obtained by laser sintering and casting techniques, luted with glass-ionomer, resin cements and acrylic/urethane-based agents.

The article offers information on the marginal misfit and microleakage of cement-retained implant-supported crown copings. It mentions that the crown copings have achieved by laser sintering and casting techniques. It also informs that single crown structures have developed with the help of laser-sintered Cobalt-Chromium (Co-Cr), vacuum-cast Co-Cr (CC) and vacuum-cast Nickel-Cr-Titanium.
