Abstract

This study investigated the machinability of cast orthopedic titanium (metastable β) alloys for possible application to dentistry and compared the results with those of cast CP Ti, Ti‐6Al‐4V, and Ti‐6Al‐7Nb, which are currently used in dentistry. Machinability was determined as the amount of metal removed with the use of an electric handpiece and a SiC abrasive wheel turning at four different rotational wheel speeds. The ratios of the amount of metal removed and the wheel volume loss (machining ratio) were also evaluated. Based on these two criteria, the two α + β alloys tested generally exhibited better results for most of the wheel speeds compared to all the other metals tested. The machinability of the three β alloys employed was similar or worse, depending on the speed of the wheel, compared to CP Ti. © 2002 Wiley Periodicals, Inc.
