Comparing the Clinical Accuracy of Orienation Jaw Relation Recorded With Various Commercially Available Facebows – An in Vivo Study
Objectives: To compare the clinical accuracy of orientation jaw relation of five different commercially available articulator facebow sysems.
Methods: The accuracy of facebow transfer in the reproduction of the molar condylar distance(MCD) for subjects wih small, medium and large intercondylar distance(ICD) were compared across Artex(n=18), Denar(n=18), Hanau(n=18), Stratos(n=18) and Whipmix(n=18) facebows against the CBCT reference measurement. Oneway ANOVA(post hoc Bonferroni test) was used to analyze the variation across diferent groups.
Results: Hanau(0.15 ± 0.18) and Stratos(0.23 ± 0.33) facebow articulator systems had significantly lesser variation in the MCD compared to the Artex (0.58 ± 0.30), Denar (1.07 ± 0.27) and Whipmix(1.25 ± 0.31) facebow articulator systems (p<0.001).
Conclusions: Hanau and Stratos facebow articulator systems appear to be significantly more accurate compared to the Artex, Denar and Whipmix facebow articulator systems and so can be considered as the system of choice to fabricate complex dental restorations.
