Aim: The aim of this study was to evaluate the occlusal plane inclination using various facebow systems in comparison with standard cephalometric radiographs.

Materials and Methods: Twenty subjects were selected following inclusion and exclusion criteria and lateral cephalograms were taken. Occlusal Plane Inclination (OPI) between occlusal plane and Frankfort horizontal plane (FHP) was determined and taken as control group. Two maxillary impressions were made for each subject and casts were poured. Facebow transfer was made with Hanau Spring bow and Quick mount facebow and mounted on Hanau wide vue and Whip mix articulators respectively. OPA on mounted casts were measured using Universal bevel protractor and taken as test groups and compared with that of standard cephalometric values. Then all values were subjected to statistical analysis for comparison using SPSS software version 22 IBM Corp.

Results: Shows a significant difference between Cephalometric and Hanau facebow system groups 1.9° (p = 0.046), Cephalometric and Whip-mix facebow system groups 3.6° (p = 0.001) and Hanau and Whip mix facebow system groups 1.7° (p = 0.013).

Conclusion: Sagittal inclination of occlusal plane of maxillary casts mounted on Hanau wide vue articulator was nearer to the standard cephalometric value. Hence, the Hanau facebow system was accurate when compared to that of Quick mount facebow system.
