3 Type1 Misalignment Side of Laterality Characteristics - C1 laterality on the same side ofangular rotation- Contralateral acute angle- Skull is parallel to vertical axis- C1 is above parallelSide of Laterality
4 Type2 Misalignment Side of Laterality Characteristics Mainly by Skull - C1 laterality on the opposite side ofangular rotation- Ipsilateral acute angle- Skull is tipped toward vertical axis- C1 remains fairly horizontal- Laterality produced mainly by skullMainly bySkullSide of Laterality
5 Type3 Misalignment Side of Laterality Directly by Skull Characteristics- C1 laterality on the same side ofskull tipping- No angular rotation- C1 remains fairly horizontal- Laterality produced by skull tippingDirectly bySkullSide of Laterality
6 Type4 Misalignment Side of Laterality Characteristics - C1 laterality on the same side ofangular rotation- Contralateral acute angle- Skull is tilted away from vertical axis- C1 is above parallelSide of Laterality

8 How to Correct Misalignment? Combination of the Head piece placement and Triceps pullPatient placement is extremely crucial!Using 3-D Xray (Lateral, Nasium, Vertex) to analyze how to set the patient on the table and specific correction vector.
14 C/A? Condylar circle over Axial circle C/A is the specific vector which allows both condylar circle and axial circle to rotate the same distance, but different speed.C/A is unique to each individualCan be calculated. C/A=(A-C)/2
18 C/A?Type 1The vector is always higher than C/A in order to affect lower angle.Type 2&3The vector is always lower than C/A in order to affect head tilt.Type 4The vector is close to C/A because both lower angle and head tilt should be corrected at the same time.
