The aim of this study was to evaluate the influence different superimposition methods on accuracy and predictability conventional virtual diagnostic setups. Ten finished cases were used make a setup setup. Second molars not moved in two situations allow reference for superimposition. Conventional setups superimposed compared by second molar registration whole surface best fit method (WSBF). pos...
