Abstract

PURPOSE:To secrete a proper saliva by comparing a saliva quantity secreted by a permanent tooth articulation and the saliva quantity secreted by an artificial tooth articulation and executing the articulation adjustment with an articulator so that the compared articulating quantity can be approximately the same quantity. CONSTITUTION:A pressure sensor 2 is installed to a permanent tooth 1 or an artificial tooth 9 in accordance with a tooth column, articulation pressure data are fetched into a controller 3, stored into a memory 4 and displayed at an indicator 5. The saliva secreted in a mouth is collected by a means to absorb it by a saliva mining pipe, stored into a container and compared with the saliva quantity measured beforehand. The articulation adjustment is executed with a suitable articulator so that the saliva quantity secreted by the articulation of the artificial tooth 9 can be approximately matched to the saliva quantity measured beforehand. Thus, the artificial tooth to obtain the secretion of the proper saliva can be manufactured and the artificial tooth with a good physiological action can be obtained.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is designed to secrete appropriate saliva during intraoral examinations for creating functionally accurate dental prostheses such as denture bases, bridge dentures, and dental crowns. Regarding effective occlusal inspection methods.

[Conventional technology] For patients with missing teeth, artificially restoring the function of the teeth using dental prostheses such as denture bases, and helping to restore and maintain various oral functions, is an effective way to maintain health. It is a treatment method.

Conventionally, when manufacturing dental prostheses such as denture bases, the interocclusal relationship in the oral cavity was first examined, a treatment policy was decided and designed, and then a mold was taken and a working model was created. When attached to an articulator, a dental prosthesis is created by reproducing the patient's intraoral movements and interocclusal relationships.

The manufactured prosthesis is actually installed in the patient's mouth and the occlusal adjustment is completed.

However, dental prostheses such as denture bases manufactured in this way do not fully reproduce the original masticatory function by producing enough saliva when chewed well, and are currently causing problems. 0In addition to the mechanical function of chewing, chewing is an oral function that secretes sufficient saliva in response to the stimulus of taking in food, promotes chemical digestion, and is an important oral function for systemic physiological functions. . Therefore, a prosthesis that restores oral function must not only adjust the occlusal relationship, but must also be designed to provide a normal occlusal position and interocclusal relationship in which sufficient saliva is secreted.

By the way, human saliva contains digestive juices, including MS substances such as mucin, amino acids, sodium, potassium, and calcium, digestive enzymes such as amylase, maltase, and lipase, and salivary gland hormones that are important for maintaining health. The complex protein extracted from saliva is
When administered intramuscularly or orally, it is known to have physiological effects such as lowering serum calcium, increasing the number of circulating white blood cells, and lowering serum citric acid. It is known that people with strong teeth have good saliva secretion and are healthy, while people with weak teeth have poor saliva secretion and are more likely to get sick.

[Problems to be Solved by the Invention] In all of the above-mentioned conventional techniques, only the appropriateness of occlusion is adjusted by the articulator, and saliva secretion, which is important for human health, is not taken into account. .

For this reason, even if the occlusion of the dentures is appropriate, saliva secretion is insufficient and the body tends to become weak when using dentures, and this problem is especially noticeable in patients whose teeth are weakened down to the roots. It was expressed in

Therefore, an object of the present invention is to provide an effective occlusal inspection method for secreting appropriate saliva.

[Means for Solving the Problems] In order to achieve the above object, the occlusal inspection method of the present invention measures the amount of saliva secreted into the oral cavity when the patient's permanent teeth are bitten in a normal occlusal position with a predetermined occlusal pressure. a step of measuring the amount of saliva secreted into the oral cavity when the patient bites with the denture in the normal occlusal position according to a predetermined occlusal pressure; This method consists of a step of comparing the amount of saliva and the amount of saliva secreted by occlusion of the denture, and a step of adjusting the occlusion using an articulator so that the compared amounts of saliva are approximately the same amount.

[Example] Hereinafter, an example of the present invention will be described with reference to the accompanying drawings.

First, as shown in Figure 1, when the patient's permanent teeth 1 are fully aligned (approximately 10 to 30 teeth), the amount of saliva secreted into the oral cavity is measured when the patient occlusions in the normal occlusal position with a predetermined occlusal pressure. .

This is JP-A No. 61-25547, JP-A No. 61-2
Using a well-known occlusal pressure measuring device known from Publication No. 57641, etc., a plurality of pressure sensors 2 are attached to the permanent teeth 1 according to the dentition, and occlusal pressure data is sent to a controller 3 consisting of a computer via an amplifier 3A. It is captured and stored in the memory 4 and displayed on the display 5, and the user bites for a predetermined period of time under conditions such as viewing food at a predetermined occlusal pressure while looking at this display.

Next, as shown in FIG. 2, the saliva 6 secreted into the patient's oral cavity by the above-mentioned occlusion is collected by means such as suctioning through a saliva collection tube 7, and placed in a graduated container 8 as shown in FIG. 3(A). Measure the amount of saliva by placing the patient in a container or other means.

Next, as shown in FIG. 4, the amount of saliva secreted into the oral cavity when the patient bites at a predetermined occlusal pressure at a normal occlusal position while wearing the denture 9 is measured.

This involves using the occlusal pressure measurement device, attaching the pressure sensor 2 to the denture 9 according to the dentition, importing the occlusal pressure data into the controller 3, storing it in the memory 4, and displaying it on the display 5. The occlusal pressure data of the permanent teeth 1 previously stored in the memory 4 is displayed on the display 5, the two are compared, and the denture 9 is adjusted to a predetermined occlusal pressure under the same situation such as looking at food. Time bite.

Next, saliva 6 secreted into the patient's oral cavity by the above-mentioned occlusion
A is collected by means such as suctioning through the saliva collecting tube 7 in the same manner as shown in FIG. 2, and is stored in a container 8 as shown in FIG. 3 (B) and compared with the amount of saliva measured in advance.

Then, as shown in FIG. 5, the measurement of the saliva 6A and the occlusion adjustment are repeated so that the amount of saliva 6A secreted by the occlusion of the denture 9 substantially matches the amount of saliva 6 measured in advance, and the appropriate articulator 10 is adjusted. For example, using
Japanese Patent Publication No. 57-9817, Japanese Patent Application Publication No. 61-2
Adjust the occlusion in an appropriate direction as shown in Publication No. 84243, etc. If the predetermined occlusal pressure is not reached when wearing the denture 9, calculate the amount of saliva corresponding to the age addition and the positive occlusal ratio, and adjust according to the calculation result. Adjust the occlusion so that a sufficient amount of saliva can be obtained.

In this way, the patient's permanent teeth 1 are aligned (10
The amount of saliva 6 secreted into the oral cavity under specified circumstances when biting with a predetermined occlusal pressure was measured in advance during the process of manufacturing the patient's dentures, with the dentures 9 attached to the patient. , the amount of saliva 6A secreted into the oral cavity under similar predetermined conditions when biting with a predetermined occlusal pressure is measured, and such measurements and occlusal adjustments are repeated until this measured amount approximately matches the previously measured amount. Since the occlusal adjustment is performed in this manner, it is possible to manufacture a denture that allows proper secretion of saliva, and it is possible to obtain a denture that has good physiological effects.

Note that the present invention is not limited to the above-mentioned embodiments, and various modifications can be made within the scope of the gist of the present invention.

[Effects of the Invention] The present invention includes a step of measuring in advance the amount of saliva secreted into the oral cavity when the patient's permanent teeth bite at a predetermined occlusal pressure at a normal occlusal position, and a step of measuring the amount of saliva secreted into the oral cavity in response to a predetermined occlusal pressure at the normal occlusal position. a step of measuring the amount of saliva secreted into the oral cavity when the patient bites with the denture, and a step of comparing the amount of saliva secreted by occluding the permanent teeth and the amount of saliva secreted by occluding the dentures against a predetermined occlusal pressure; It is possible to provide an occlusal inspection method that is effective for secreting appropriate saliva, and includes a step of adjusting occlusion using an articulator so that the compared amounts of saliva are approximately the same.
