Evaluation of the Gothic arch tracing(According to Prof. Gerber)

• Classical pointe form– The symmetry indicates

an undisturbed movement sequence in the joint and uniform muscle guidance

Herbert Frick ICDE

• Classical flat shape– This figure indicates pronounced lateral motion of condyles

in the joint

Herbert Frick ICDE

• Asymmetrical shape – this figure indicates a

pronounced impediment in the protrusive excursion of the left mandibular joint

Herbert Frick ICDE

• Arrow point is non-existant– This figure indicates weak to

slack movement, particularly of retrusive excursion components; registration must be repeated and more concise motion are requested

Herbert Frick ICDE

• The vertical line extends over the arrow point– This tracing was created

by either forcefully pulling or pushing back the mandible

– The figure may also been traced with a protruding mandible

Herbert Frick ICDE

• A miniature arrow– This figure indicates cramped movements, poorly placed

and painful registration plates, long-term absence of teeth with obstructed movements in the joints, defective prosthesis, etc.

Fixation of the centric occlusion

• Checking the centric with secured record bite basis

• Aligning the funnel-shaped opening of the fixing plate with the needle point

Herbert Frick ICDE

• Fabricating the key with fast setting plaster or hard silicone

• Marking the central line
