In addition, with the aging of the population, edentulous jaws have been created, and the number of patients wearing dentures is increasing. In determining the jaw position of these patients, X-ray examination, impression sampling, occlusal sampling, etc. are performed to create a study model or working model, and the dentist's anatomical knowledge, intuition and patient's prosthesis are attached. I decided to rely on that feeling. However, the dentist's method of inducing the maxillary position or sensing the patient's sensation under tension is a state in which pronunciation of the daily life, movements of the oral muscles such as eating and drinking are ignored, and is often different from habitual exercise. In some cases, a semi-adjustable articulator, a fully adjustable articulator, an occlusal plane plate, etc. are used in an attempt to improve this. Furthermore, Ojima et al. Have proposed a dynorty system combining a semi-adjustable articulator and an occlusal plane plate that can move up and down based on the average anatomical data of Japanese people.

Ignore what you do, take occlusion, take impression,
Based on this, a study model or working model was prepared, teeth were deleted, a prosthesis was attached, and the normal jaw position was estimated. In some cases, such treatment may worsen the symptoms. Ojima et al. Have proposed a diversity system that combines an occlusal plane plate that can move up and down. In this case as well, it is not possible to obtain the normal jaw position in many cases because it is not a method for measuring the normal jaw position considering the movement of the jaw up, down, front, back, left, and right, and it is difficult to make fine adjustments because it cannot be adjusted in the oral cavity. Yes, there was a need for improvement.

判定できることを見出した。[Means for Solving the Problems] The inventors of the present invention developed a maximum occlusal pressure in the normal jaw position as a method for determining the jaw position in the oral cavity in consideration of the movement of the jaw in the up-down direction and the front-back, left-right direction. Using the jaw lift amount measuring spacer and the occlusal pressure measuring instrument, guide the jaw to the position where the maximum occlusal pressure is obtained, and then position the dentition in the vertical direction or the position of the jaw. The normal jaw position can be determined by a simple method, by determining from the thickness of the lift amount measuring spacer, and by reading the position of the dentition or jaw, for example, by transferring it to a plastic substance to read the deviation to the front, rear, left and right. Found.

問題点を解決できることを見出した。In addition, in order to give a quantitative reading to the front-back and left-right deviation, a tray with a grid-like scale having a grid-like scale on the occlusal surface and the cheek side is used, and this is used together with the jaw lift amount measuring space. Guide the jaw to the position where the maximum occlusal pressure can be obtained by combining the tool and the occlusal pressure measurement device, and then determine the vertical dentition or the position of the jaw from the thickness of the jaw lift amount measurement spacer before and after. It has been found that the problems can be solved by directly or indirectly transferring by reading a scale with a shift in the left-right direction on a tray.

It was devised so that the patient's sensation (eg swallowing) could also be confirmed by combining the above.

口腔内で正常顎位を測定する方法に関する。The present invention relates to a method for measuring a normal jaw position by finding out the occlusal position where the maximum occlusal pressure is obtained, paying attention to the occurrence of the maximum occlusal pressure in the normal jaw position. The first invention uses a jaw lift amount measuring spacer and an occlusal pressure measuring instrument to determine the occlusal position at which the maximum occlusal pressure can be obtained, and the position of the dentition or jaws in the up, down, front, back, left, and right directions at that time is determined by, for example, plasticity. It relates to a method for measuring a normal jaw position in the oral cavity, which is characterized in that it is transferred to a substance and read.

These occlusal pressure sensors are used by inserting them between spacers, and are thin and highly accurate with a thickness of about 100 μm, and are suitable for carrying out the present invention. The recording of the occlusal position at which the maximum occlusal pressure is obtained is performed by transferring the position of the dentition or the jaw at that time to, for example, a plastic substance, and thereby the normal jaw position is determined. As the plastic material, a silicone-based impression material, an alginate impression material, a modeling compound, or the like is used. When measuring the positional relationship between the upper and lower jaws, it is used to take an impression of the upper and lower tooth patterns and / or jaw shapes in advance and reproduce the positional relationship between the normal jaw positions.

(2) Obtain the impression of all jaws as usual, manufacture a plaster model, accurately reproduce the occlusal height and the front, rear, left, and right positions measured in (1) on the articulator, and mount the working model. (3) On the working model, occlusal ridge construction and artificial tooth arrangement are performed.

It has become possible. Further, in the production of all dentures, the time required for occlusal acquisition at the occlusal ridge is shortened, and the artificial tooth arrangement can be directly performed, which reduces the number of patient visits.
