It is the bridge of the usual incisal teeth. In this case, though a prosthesis is made referenced on the position of the canine tooth.

If the position of the canine tooth is wrong in the right and left...........

A photograph inside the mouth

Mark the cusp of the model of the upper jaw in the occlusion rim in the dentate Arch.	Confirm that it intersects vertically in the Median-Sadittal-plane.	Confirm that it is parallel in the Camper's line.

It adapts the occlusion rim in the Dentate Arch in the mouth.
Adjust a front view with the occlusal plane plate to intersect vertically in the median-sadittal-plane, and, adjust a lateral view to become parallel in the Camper's line.
And this patient must try so that it isn't confused because the position of the left-right eye is wrong.
At this time, you measure a distance to the incisal angle of the incisal tooth from the arbitrary hinge axis point.

You transfer the distance to the incisal angle of the incisal tooth from the arbitrary hinge axis point measured with the patient in the Articulator, and put an occlusion rim in the dentate arch on the template (occlusal plane support unit) set on the Articulator, and it mounts the upper jaw model.

On that occasion, write down an an anterior median line from the patient, and write down an a posteior median line in the occlusion rim in the dentate Arch on the model.

By this, the upper jaw model is mounted with the environment which is the same as the condition which a patient is presumed directly by an Articulator.

The next photographs is based steps.

If a wax up is done in accordance with the template (occlusal plane support unit), the position of the incisal edge is only good.

No thing needs to be worried about a tooth shaft, a tooth length, and others.

An occlusal plane by the occlusion rim in the dentate arch employed first can reappear as it is in the prosthesis.
