Special measuring ruler for oral cavity gap

Abstract

The invention discloses a special measuring ruler for the oral cavity gap. The measuring ruler comprises a main body and a measuring part, wherein the measuring part is arranged at one end of the mainbody and is vertical to the main body; the measuring part is one of two halves which have the same structures obtained by halving a cone along the center vertical surface; the bottom of the measuringpart is fixed on the main body, the bottom radius of the measuring part is 1.0 mm, and the top radius of the measuring part is 0.1 mm; the arc surface of the measuring part is aligned with the side surface of the main body; a first graduated scale is arranged on the outer side wall of the half cone along the height direction; the measuring range of the first graduated scale is 0.1 to 1.0 mm; andthe precision of the first graduated scale is 0.1 mm. According to the measuring ruler disclosed by the invention, the measuring part and the main body are vertically installed to form the measuring ruler and the measuring part is the half cone; in a use process, the half cone is put into the tooth gap position, the tooth gap space can be directly read through the radius of the located cone circumference of the tooth gap, so that the gap between the front tooth and the rear tooth is conveniently measured; and a first main ruler and a second main ruler matched with the measuring ruler are installed, so that the goal of directly measuring the oral cavity gap outside oral cavity beside a chair is achieved.

Description

technical field [0001] The invention relates to a special measuring ruler for oral cavity space, which belongs to the technical field of dental space measurement. Background technique [0002] Intraoral gap measurement is helpful for doctors to understand the patient's tooth alignment. At present, there are two methods for measuring the gap in the oral cavity: one is through the model analysis method, that is, it needs to be measured outside the oral cavity with a special orthodontic ruler after taking the mold and filling the mold. The gap data measured by this measurement method are accurate, but the measurement It takes a long time, and the direct measurement of the intraoral space cannot be quickly completed by the chair, which is not conducive to the inspection and evaluation in orthodontic treatment; the second is to measure through the measuring device. The measurement of the gap is difficult to measure the gap between the posterior teeth. The reason is that it is to...

At present, there are two methods for measuring the gap in the oral cavity: one is through the model analysis method, that is, it needs to be measured outside the oral cavity with a special orthodontic ruler after taking the mold and filling the mold. The gap data measured by this measurement method are accurate, but the measurement It takes a long time, and the direct measurement of the intraoral space cannot be quickly completed by the chair, which is not conducive to the inspection and evaluation in orthodontic treatment; the second is to measure through the measuring device. The measurement of the gap is difficult to measure the gap between the posterior teeth, because the volume is too large to extend into the oral cavity to measure the gap between the posterior teeth, and the scale is close to the measuring end, so it cannot be read outside the oral cavity

The invention patent with the patent number "201521051288.1" discloses a interdental gap measuring device. Although it solves the problem of two-handed operation, it is still difficult to measure the gap between the posterior teeth and take readings outside the oral cavity, and the measurement range and accuracy when measuring the tiny gap has limitations
