What is In Vitro Comparison of the Maxillary Occlusal Plane Orientation Obtained with Five Facebow Systems about?

## Statement of problem: The sagittal and coronal orientation of the maxillary occlusal plane plays an important role in the esthetic and functional outcome of dental prostheses. the accuracy of contemporary facebow transfer systems in transferring this orientation to semiadjustable articulators has not been quantified. ## Purpose: The purpose of this in vitro investigation was to analyze the sagittal and coronal orientation of the occlusal plane with 5 different facebow transfer systems. ## Material and methods: A phantom head containing a maxillary typodont (control) was oriented so that the frankfort horizontal plane was horizontal. the angle between the occlusal plane of the maxillary arch of the phantom head and the frankfort horizontal plane was measured along the sagittal and coronal planes with a digital protractor. fifteen facebow records using each of 5 facebow transfer systems (test groups) were made on the phantom head containing the maxillary typodont. diagnostic casts of the maxillary typodont were mounted on semi-adjustable arcon articulators from the facebow records. the same angles measured on the control were measured on the test groups. these angles were compared
