Dimensional fit of cast Ti-restorations
Håkon Herø, Morten Syverud, Morten Waarli and Erik Kleven | March 2nd 1993
Undersizing of cast Ti crowns has been reported to be a problem. The diameter of standardized, cylindrical crowns was studied in this investigation using a photographic technique and cold moulds. The results show that the dimensional problem can be avoided by selecting a standard phosphate-bonded investment with a sufficiently high thermal expansion coefficient.
