Fit Accuracy of Removable Partial Denture Frameworks Fabricated with CAD/CAM, Rapid Prototyping, and Conventional Techniques: A Systematic Review

Table 4

Comparison of fit and accuracy of RPD frameworks constructed with conventional and digital techniques.

Digital framework	Material	Fit accuracy (μm)
		Mean	SD
CAD/CAM	Co-Cr alloy and PEEK	41.677	15.546
SLM/SLS	Co-Cr alloy	97.452	32.575
Conventional framework
Lost wax technique	Co-Cr alloy	114.063	77.704

Co-Cr: cobalt chromium; PEEK: polyetheretherketone; CAD/CAM: computer-aided designing and computer-aided manufacturing; SLM: selective laser melting; SD: standard deviation; SLS: selective laser sintering; μm: micrometer; RPD: removable partial denture.
