Abstract
Provided is an instrument capable of performing maxillomandibular registration after an occlusal vertical dimension is accurately registered in the oral cavity of a patient. With the use of these instruments in the oral cavity, maxillomandibular registration can be performed and a prosthesis can be produced in a state where occlusal stability is reproduced by point contact. Further, with the use of an articulator capable of reproducing the shape and movement of the mandible, a prosthesis can be produced regardless of the experience of the operator.

An occlusion recording instrument which performs occlusal registration after an occlusal vertical dimension is determined, wherein
- the occlusion recording instrument is made of a hard material,
- the occlusion recording instrument has a length of a mesiodistal distance which requires prosthetic treatment, and
- the occlusion recording instrument has a flat plate shape, or includes a protruding portion.
An articulator comprising:
- an upper arch portion configured to support a maxilla model;
- a lower arch portion configured to support a mandible model;
- and
- a strut configured to support an upper arch, wherein
- the strut equips an upper arch support portion, which comes into contact with the upper arch portion or the lower arch portion, at an end portion of the strut,
- the upper arch portion and the lower arch portion equip a receiving portion which comes into contact with the upper arch support portion,
- the upper arch support portion has a shape imitating a condyle of a patient,
- the receiving portion has a shape imitating a fossa mandibularis, and
- the receiving portion is configured to be replaceable corresponding to the shape of the mandible of the patient.
An articulator comprising:
- an upper arch portion configured to support a maxilla model;
- a lower arch portion configured to support a mandible model;
- and
- a maxilla mounting plate and a mandible mounting plate, wherein
- the mandible mounting plate is configured to be movable so as to allow the mandible mounting plate to apply movement similar to rotation and pendulum motion defined by Monson's spherical theory.
