PURPOSE Previous studies considering retention of cast metal restorations to implant abutments incorporated some degree of frictional fit due to internal surface nodules and roughness of the restoration. In comparison, CAD/CAM restorations have minimal surface irregularities, possibly impacting retention. There is insufficient knowledge of retentive force of CAD/CAM restorations to titanium abu...

We show that the simple fact that a monopolist sells a good in units which are indivisible may well induce him to select a quality for his product which is not the highest one, even if no cost of any sort is attached to quality improvement. ∗CORE, université catholique de Louvain †CEREC, Facultés universitaires Saint-Louis & CORE, université catholique de Louvain 1.

Dentists can be a funny bunch. We all, for the most part, like new technology and gadgets, yet it is very difficult for some of us to change the way we do things, especially when it comes to our practices. Some of our colleagues would be content if they could continue doing procedures and using clinical techniques just as they learned them in dental school. If they never had to learn anything n...

Dual cure resin cements polymerize in the self-cure mode when light cannot pass through. Purpose: Measure bond strength of 4 dual cure resin cements to dentin/enamel in self – cure mode. Method: Pretreated e.max rods were cemented to molars ground to flat dentin/enamel using 4 adhesive/cement combinations under force (100g) for 8 minutes. The experiment repeated with specimens in incubator (37°...
