Embodiment approach 1

[0043] The bite recording instrument 1 of the present invention is based on a hard material, and its shape is formed as a substantially flat member, or further has a convex portion on a flat member, or has a shape of a convex portion and a concave portion ( figure 1 ). Because there are various states of the teeth that require restorative treatment, the shape of the occlusal teeth, etc., and the states of the teeth that require occlusal sampling, and what kind of restorative treatment is required by the patient is also varied, so , you can use the appropriate bite registration device according to the situation. The bite recording instrument 1 of the present invention is made of a hard material, so the bite sampling can be performed while the outer pteroid muscle is active, and it will not be broken even if the patient bites it, and it will not be deformed when taken out of the oral cavity. Therefore, accurate bite sampling can be performed regardless of the skill of the perform...

Embodiment 1

[0058] Using the occlusal recording instrument 9, take the situation of the right lower molar (molar) defect in the patient's oral cavity as an example to illustrate the method for occlusal sampling ( figure 2 ). Clamp the bite recording device with the bite paper holder and bite it in the patient's mouth, and let the patient confirm whether the bite vertical distance is appropriate. When the height is high, the convex part of the bite registration tool is cut, and when the height is low, resin is added to the convex part, and the patient is again asked to check the vertical distance of the bite in the patient's mouth. Repeatedly adjust until it becomes a suitable height, so as to determine the vertical distance of bite ( figure 2 , Bite vertical distance adjustment).

[0059] After the occlusal vertical distance is determined, the impression material is placed on the occlusal recording appliance, and the patient bites for occlusal sampling ( figure 2 , bite sampling). ...

Embodiment 2

[0063] Next, using an implant as an example, a method of using the bite registration tool 10 having a dome-shaped convex portion will be described ( image 3 ). In normal implant treatment, after fitting the superstructure to the base of the implant bridge, model acquisition and try-in of the artificial tooth are performed. However, since the upper surface of the superstructure is substantially flat, even if occlusal sampling is performed as it is, the relationship between the opposing remaining teeth and the artificial teeth to be attached cannot be reflected.

[0064] Therefore, after the superstructure is installed, a dome-shaped bite register is placed on the superstructure. Here, the protrusions 12 of the bite recording tool 10 are cut off one by one and placed on the superstructure ( image 3 , Bite recording appliance configuration).

[0065] In this state, the occlusion is confirmed on the working model, and the occlusal vertical distance ( image 3, Bite vertical ...

Abstract

Provided is an instrument capable of performing bite checking after accurately acquiring the occlusal vertical dimension within the oral cavity of a patient. Using these instruments in the oral cavitymakes it possible to perform bite checking in a state in which occlusion stability is reproduced by point contact, and to produce a prosthetic device. In addition, a prosthetic device can be producedirrespective of the experience of the operator by an articulator capable of reproducing the shape and movement of the mandible.

Description

technical field [0001] The present invention relates to a bite recording device, a method of using the device and an articulator. Background technique [0002] When you lose your teeth due to dental caries, periodontitis, etc., you can restore prosthetics such as crowns, dentures (dentures), and implants through treatment, but, for example, due to improper dentures Malocclusion caused by restorative treatment has also become a major problem. [0003] Occlusion, so-called occlusion (occlusal teeth), is beginning to be widely recognized as being very important for the health of the whole body. As we all know, malocclusion includes not only symptoms of severe temporomandibular joint disorder such as inability to open the mouth, jaw pain or numbness, but also various physical discomforts such as frozen shoulder, headache, and dizziness. Therefore, accurate occlusal sampling (occlusal sampling / occlusal extraction) is considered necessary in prosthetic treatment. [0004] Anato...
