A metallographic evaluation of porosity occurring in removable partial denture castings.
Conveniently sized sections from six removable partial denture castings were examined metallographically for porosity. Abrupt changes in cross sectional areas were the site of porosity in some specimens; also seen were small generalized areas of porosity unlikely to be disclosed radiographically.
