Abstract

This study was conducted to examine the surface condition of titanium castings after sandblasting.<BR>The specimens were made using four kinds of dental titanium investments. Two kinds of sandblasting machines were used because of the difference of removability of adhering investments after observation of the range of adhering investment, and the surface roughness (Rz) was measured. Observation by optical microscope and EPMA analysis of the cross section of the specimens were carried out.<BR>1. The order of adhering investment from no range to full range was SELEVEST CB, SELEVEST D, TINVEST CB, and T-INVEST.<BR>2. The surface roughness of the specimens were as follows:<BR>SELEVEST CB: 5.4μm, SELEVEST D: 5.9μm, T-INVEST CB: 4.9μm, and T-INVEST: 5.3μm.<BR>All specimens showed lower surface roughness than Ag-Pd-Au castings.<BR>3. The ultra thin layers of the castings made with SELEVEST were removed after sandblasting. However, about 20μm reacted layers of the castings made with T-INVEST were removed after sandblasting.<BR>4. Elements that originated from the investments remained on the surface of the specimens after sandblasting. It indicated that some of reacted layers were left after sandblasing.<BR>5. There is a good possibility that elements of the sand remained on the specimens after sandblasting.
