Thickness and Accuracy of Superplastic Ti-6Al-4V Alloy Denture Frameworks


PMID: 9171489

The thickness and adaptation of superplastic forming Ti-6Al-4V alloy denture frameworks were investigated using cross-sectional measurements. The frameworks for maxillary com plete dentures were fabricated from Ti-6Al-4V disks of thicknesses ranging from 0.75 to 1.30 mm. Although the thickness of each disk was reduced by superplastic forming, the completed framework had more than 78% of the original disk thickness. Differences in the thickness did not significantly affect either the thickness ratio of the framework to the disk or the gap discrepancy between the framework and the working cast. The accuracy of fit of the framework would satisfy ordinary clinical requirements.
