JP2001128996A - Incisive papilla measuring unit - Google Patents

Abstract

PROBLEM TO BE SOLVED: To quickly and accurately execute operation for measuring the incisive papilla in manufacturing complete denture to obtain a very accurate and stable measurement value. SOLUTION: As shown in Fig. 1, this tool for measuring the incisive papilla in manufacturing a complete denture is formed by incisive papilla measuring device body 1, a screw 2, a disc 3, a lock nut 4, and a butterfly nut 5.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION It is necessary for edentulous patients to have complete denture prostheses. In order to determine the vertical position of the end of the incisor in the manufacturing process of the complete denture, it is necessary to accurately measure the distance between the incision papillae and the nose tip, so-called accurate papillae measurement. The present invention relates to an instrument used for this nipple measurement operation.

[0002]

2. Description of the Related Art Until now, there has been no such dedicated instrument for this nipple measurement operation, and a rather rough measurement method close to visual measurement has been adopted by each dentist using a vernier caliper or a scale. The measured values obtained by such a method have large errors and have a great adverse effect on the performance of the denture.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to establish an accurate and uniform technique for easily and accurately performing a conventional unstable nipple measurement operation.

[0004]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to FIGS. 1 and 2. A long funnel with a semicircular front opening is formed into a plane as viewed from the side, and the total length is reduced. 100mm
About. Then, the front semicircular straight section is raised up several mm vertically, a notch is made to dodge the lips about 60 mm rearward from this rise, and a long hole processing for moving the screw back and forth behind this back It consists of five parts: a nipple measuring instrument body, a screw, a disk that can be moved up and down by turning the screw right and left, a lock nut, and a wing nut to temporarily fix the screw at the measurement position To be used for nipple measurement work.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 4, a method for handling this device will be described. First, a semicircular portion in front of a papillometer is inserted into the oral cavity of a patient, and a straight-line rising end of several mm is inserted backward. Lightly press against the reference point, and lightly contact the upper surface of the measuring instrument with the papillae of the upper incisor. Next, move the screw back and forth, and lightly tighten the wing nut at the appropriate position to fix the front and rear positions of the disk. Then, while rotating the disk left and right with a finger, the height is adjusted so that the peripheral edge contacts the nose tip, and the lock nut is lightly tightened to fix the vertical position of the disk. Next, the nipple measuring device is taken out of the oral cavity, and the height from the upper surface of the measuring device main body to the peripheral edge of the disk is measured. If the reference value is calculated using this measured value, an accurate vertical position of the incisal end can be determined.

[0006]

According to the present invention, individual differences among practitioners are almost eliminated, accurate nipple measurement can be performed quickly and in a short time, and the occlusal height of the complete denture can be easily secured. .

Claims (1)

[Claims] 1. A flat surface as viewed from the side of a long neck funnel with a semicircular front opening is formed, and the total length is about 100 mm. Then, the front semi-circular straight part is raised vertically by several mm, a notch for dodging the lips about 60 mm rearward from this rising, and a long hole processing to move the screw back and forth behind this back. Consisting of five parts: a nipple measuring device body, a screw, a disk that can be moved up and down by turning the screw to the center and turning left and right, a lock nut, and a wing nut to temporarily fix the screw at the measurement position Used in the nipple measurement (measuring the distance between the incisor nipple and the nose tip) during the complete denture manufacturing process.
