- the maxillary frame (51) of the articulator (5) and the plane of Frankfurt (FH; 0r-Po) are parallel, and this relationship is fundamental.
- the angle between the occlusal plane (Occlusal Plane; U1-o) and the Frankfurt plane is about 10 °
- the Barkwill angle the imaginary line connecting the center of the upper surface of the mandible and the incisor point is The angle formed is about 25 °
- the Campel plane nosal hearing line, prosthetic plane
- the occlusal plane are almost parallel
- one side of the Bonwill Triangle is about 10 cm long.
- the present inventor performed analysis using jaw movement data measured using a 6-free jaw movement measuring device and lateral cephalometric radiographs, and considered the following.
- the pendulum movement of the mandibular condyle is a part of an arc with a radius of about 12 strokes centered on the center of the joint nodule.
- the starting point (the cusp position) is about 33 ° below the Frankfurt plane (horizontal plane). This is an angular acceleration motion of about 90 ° below the front.
- the normal direction of the condylar sphere at the departure point is the vector direction of the force applied to the mandibular condyle at the cusp-fitting position. This normal line is the vertex (dental point) of the oral cone (dental cone).
- the angle formed by the occlusal plane connecting the midpoint of the upper and lower central incisors and the midpoint of the upper and lower first molars and the Frankfurt plane (horizontal plane) is about 10 ° on average in Japanese adults.
- Iizuka, Ishikawa; Reference values of case analysis method using head radiographs-Japanese adult male and female normal occlusion group, Nippon Orthodontics Journal of the Dental Society 16, 195 7] since the center line of the oral cone is orthogonal to the occlusal plane, the oral cone axis is about 10 with respect to the vertical.
- Lean forward Since the mode of movement is basically forward (frontal plane direction), it will inevitably need a bouncing element that leans forward.
- the mandible has a skull balance function (pendulum movement of the mandibular weight), but the lower jaw in the mandibular rest position (opening amount about 3 mm, opening degree about 2 °)
- the condyle makes a tangential motion about 50 ° anteriorly downward with respect to the Frankfurt plane (horizontal plane).
- the steepness is about 40 °, which is steeper than 33 °.
- the mandibular suspension movement at the time of natural opening suspended by the lateral ligament and temporal muscle is considered to be the pendulum movement of the mandibular weight around the vertex of the oral cone.
- the cusp position which is the final resting point of the upper and lower jaws
- the lower jaw molar which is the closing point of the lower jaw
- the line connecting the cusps of is arranged on an arc or a sphere centered on the center of the pendulum motion.
- this makes it possible to harmonize the pendulum movement of the mandibular weight, which is a posture balance mechanism, with dental occlusion.
- the opening and closing movements of the upper and lower jaw involve coordinated movement of the upper cervical spine.

- the joint has a high degree of freedom in rotational movement.
- the skull is about 5 with the rotation center of the occipital condyle as the rotation axis.
- the normal of condylar movement is the rotation center of the first cervical vertebra (the flexion of the lateral atlanto-axial joint, the extension axis, near the center of the dendrite, this position is the axle joint) (Corresponds to the rotation center of the median atlanto-axial joint), so that there is a high degree of freedom of movement between the first cervical vertebra and the second cervical vertebra (lateral atlanto-axial joint).
- the first cervical vertebra rotates about 5 ° posteriorly, and the normal of condylar movement passes through the center of rotation of the second cervical vertebra (the umbilical center of the third cervical vertebra) with an opening of about 15 mm. 2.
- the degree of freedom of movement is high between the cervical and third cervical vertebrae (the intervertebral disc and the facet joint).
- the normal of condylar movement is parallel to the vertical line (the mandibular condyle is suspended just below by the lateral ligament). Therefore, the posterior rotational movement below the third cervical vertebra acts to allow the mandibular condyle to pass over the joint nodule.
- About 10 for the Frankfurt plane Since the occlusal plane with the anterior inclination always passes through the rotation center of the first cervical vertebra (near the center of the tooth process) during opening and closing movement, setting the occlusal plane is important.
