Description

An oral multifunctional ruler

technical field

The utility model relates to the technical field of oral tooth measurement, in particular to an oral multifunctional ruler.

Background technique

In the process of dental implant surgery, the correct implant site is very important for the long-term stability of implant restoration. In order to improve the accuracy of implantation, more and more control sites such as surgical guides and surgical navigation are used in clinical practice to guide implants. implantation. However, on the one hand, this type of method has disadvantages such as complicated process and high cost, and most cases are still implanted by free hand. Defects in the site can only be found during inspection.

Before performing dental implant surgery, it is necessary to determine whether the size of the missing tooth space can meet the minimum diameter implant placement. During implant surgery, it is necessary to locate the implant site. The gap between the implant and the implant is enough to meet the minimum requirements. During oral examination, it is necessary to accurately measure the degree of mouth opening and the degree of deviation of the mouth opening; during tooth preparation, it is necessary to measure the size of the tooth and judge the degree of grinding of the tooth tissue. Whether the thickness meets the restoration space requirements; in addition, the periodontal probe also needs to measure the depth of the periodontal zone.

However, the current oral measuring rulers have the following problems: 1. The implantation guides of various implant manufacturers are only suitable for their own products and lack versatility; 2. In the process of clinical operation, multiple measurements need to be performed at the same time, which increases the use of testing The number of instruments increases the time and inconvenience of the operation.

Utility model content

The utility model aims to provide an oral multi-function ruler, which solves the problems that the current oral measuring ruler lacks versatility and cannot integrate various detection instruments. , setting the first tooth circle and the second tooth circle can ensure the precise placement of the implant, and the new type is convenient to use and has complete functions.

In order to realize the above-mentioned technical effect, the technical scheme adopted by the present utility model is as follows:

An oral multifunctional ruler, comprising a ruler part and a positioning ruler, the ruler part and the positioning ruler are integrally formed, the positioning ruler is provided with a first tooth circle and a second tooth circle, the first tooth circle and The second tooth circles are superimposed and arranged, and a probe is connected to the left side of the straight edge through a rotating shaft.

Preferably, the probe and the ruler part are in an interference fit, and the ruler part is provided with a limiting block to limit the included angle between the probe and the vertical direction to be 45°.

Preferably, the length of the ruler is 30mm, the width is 2mm, and the thickness is 1.5mm, the length of the positioning ruler is 7mm, the width is 6mm, and the thickness is 1.5mm, and the length of the probe is 8mm and the width is 1.5mm. is 1mm and the thickness is 0.5mm.

Preferably, the center of the first tooth circle is located at the coordinates (4, 2.5) of the positioning ruler, and the center of the second tooth circle is located at the coordinates (4, 1.5) of the positioning ruler.

Preferably, the diameters of the first tooth circle and the second tooth circle are 2.5 mm.

Compared with the prior art, the beneficial effects of the present utility model are:

1. A positioning ruler is set up, with a measurement interval of 6mm and 7mm, which can immediately measure whether the size of the missing tooth space meets the requirements of implant restoration, which solves the current problem of inability to accurately determine whether the remaining space can be used for dental implants during oral surgery testing. ;

2. The first tooth circle and the second tooth circle are set in the positioning ruler, which can ensure the accurate placement of the implant, and at the same time make the buccal bone volume of the labial and buccal side of the final hole preparation to be 2mm, which can ensure the long-term stability of the bone volume after repair. Due to the high cost of using customized personalized guides in implant surgery, it is rarely used clinically, and freehand operation is usually used. Problems affecting subsequent restorative treatment;

3. The thickness of the ruler part and the positioning ruler of this new type of multi-function ruler is 1.5mm, and the width of the ruler part is 2mm. After placement, it can quickly measure whether the space between implants and adjacent teeth, implants and implants meets the minimum requirements. The space requirement solves the problem that the gap between the implant and the temporary tooth, and the implant and the implant cannot be accurately judged during the current implant operation, resulting in bone resorption and affecting the final restoration effect;

4. The new multi-function ruler can measure the degree of mouth opening and the degree of mandibular deviation at the same time, and can be accurate to 1mm, which solves the problem that the current mouth opening and mandibular deviation cannot be accurately measured during the inspection of the mouth, which affects the severity of the disease. question of judgment.

Detailed ways

The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model, but not to limit the present utility model.

Example:

Referring to accompanying drawing 1, a kind of oral multi-function ruler, including ruler part 2 and positioning ruler 3, described ruler part 2 and positioning ruler 3 are integrally formed, and described positioning ruler 3 is provided with first tooth circle 4 and second Two tooth circles 5, the first tooth circle 4 and the second tooth circle 5 are superimposed and arranged, which can take into account the requirements for preparing holes for implants with various diameters. , periodontal pocket measurements can be performed.

The probe 1 and the ruler part 2 are in an interference fit, and the ruler part 2 is provided with a limiting block 7 to limit the angle between the probe 1 and the vertical direction to be 45°, so as to prevent the probe 1 from rotating excessively in actual use. When in use, probe 1 into the periodontal pocket with a force of 20g to measure the periodontal depth, and the setting of 45° allows for a more comfortable holding operation.

The length of the ruler part 2 is 30mm, the width is 2mm, and the thickness is 1.5mm; the length of the positioning ruler 3 is 7mm, the width is 6mm, and the thickness is 1.5mm; the length of the probe 1 is 8mm, and the width is 1mm and the thickness is 0.5mm.

The center of the first tooth circle 4 is located at the coordinates (4, 2.5) of the positioning ruler 3, the center of the second tooth circle 5 is located at the coordinate (4, 1.5) of the positioning ruler 3, and the first tooth circle 4 and the second tooth circle 5 have a diameter of 2.5 mm.

The first tooth circle 4 and the second tooth circle 5 can perform planting positioning.

The principle and use process of the present utility model:

When implanting in the anterior aesthetic area, the width of the labial bone of the implant should be 2mm and the distance between adjacent teeth should be 1.5mm. When preparing an implant with a diameter of 4 mm, a positioning drill can be used to fix the point at the position of the center coordinate (4, 2.5) of the first tooth circle 4 . Then prepare holes in sequence, so that the prepared holes have a bone thickness of 2mm between the labial bone plates and at least 1.5mm away from the adjacent teeth. If it is required to have a 2mm gap with the adjacent teeth, the positioning drill can be placed 0.5mm outside the first tooth circle 4, that is, the first tooth circle 4 and the second tooth circle 5.

If the implant preparation with a diameter of 3.5mm is performed, the hole preparation is performed on the round edge of the first tooth circle 4, which is close to the straight edge direction, and the 2mm labial bone thickness can also be guaranteed after preparation.

When preparing the posterior teeth area, prepare to place a 5mm diameter implant. When preparing the hole, choose the center of the second tooth circle 5, that is, the position of the coordinate (4, 1.5). After the hole is prepared, the bone thickness of 1.5mm on the buccal side can be guaranteed. There is a 2mm distance from the adjacent teeth.
