Description

Technical Field

[0001] The invention relates to the technical field of dentistry, and in particular to a device and method for measuring the width of keratinized gingiva and alveolar ridge in an edentulous area. Background Art

[0002] The width of keratinized gingiva has a certain impact on the long-term success of dental implants. Some studies have shown that when the width of keratinized gingiva is <2mm, plaque accumulation and gingival inflammation around the implant will increase. However, some studies have shown that under good oral hygiene conditions, the width of keratinized gingiva has almost no effect on soft tissue inflammation, but there is a risk of increased gingival index, plaque index, and probe bleeding index.

[0003] Periodontal disease is one of the two most common oral infectious diseases in my country and the leading cause of tooth loss in adults. Surveys show that the periodontal health and oral hygiene of the middle-aged and elderly population in my country are poor, and the situation is not optimistic. Therefore, from the current situation of oral hygiene in my country, if the patient's oral implant is to be maintained in a long-term stable and effective manner, the keratinized gingiva around the implant is still very important.

[0004] Therefore, the measured value of preoperative keratinized gingival width can help us predict the prognosis risk of peri-implant gingivitis in patients, determine the necessity of keratinized gingival transplantation in advance, guide the design of surgical soft tissue incisions, etc. Considering the long-term stability and aesthetics of the implant, it is generally believed that a keratinized gingival width of 2mm is still necessary for Chinese implant sites.

[0005] When natural teeth are present, the keratinized gingiva is measured from the gingival margin to the mucogingival junction, divided into the buccal and lingual sides. Currently, the measurement of keratinized gingiva is mainly done using periodontal probes and calipers in clinical practice. However, the anatomical structure of the alveolar ridge in the edentulous area is complex, and the keratinized gingiva is not a flat and regular structure. Therefore, it is impossible to accurately measure the keratinized gingiva using periodontal probes, calipers and other measuring tools. Summary of the invention

[0006] The purpose of the present invention is to provide a device for measuring the width of keratinized gingiva and alveolar ridge in an edentulous area, so as to solve the problem that the keratinized gingiva cannot be accurately measured by the existing method of measuring the keratinized gingiva using a probe and a caliper.

[0007] In addition, the present invention also provides a measuring method based on the above measuring device.

[0008] The present invention is achieved through the following technical solutions:

[0009] A device for measuring the width of keratinized gingiva and alveolar ridge in the edentulous area, comprising a main ruler, a sliding ruler and a soft ruler;

[0010] The main ruler is an L-shaped structure, and the L-shaped structure includes a working section and a fixed section, and the fixed section is used for slidingly setting the sliding ruler;

[0011] The sliding ruler is slidably arranged on the fixed section of the main ruler, and the bottom of the sliding ruler is flush with the bottom of the working section of the main ruler;

[0012] One end of the soft ruler is fixed to the working end of the working section of the main ruler, and the other end is slidably arranged on the working end of the sliding ruler. The working end can be clamped on the buccal and lingual side of the edentulous area. The soft ruler is provided with a measuring unit for characterizing the width of the alveolar ridge, and the soft ruler is made of a flexible material;

[0013] At least one of the sliding ruler and the working section is provided with a scale for measuring the gingival width.

[0014] The flexible material used in the present invention is a prior art, which is flexible but not elastic. Specifically, flexibility means that the tape measure can conform to the shape of the alveolar ridge and be distributed on the keratinized gingival surface of the edentulous area. Inelasticity specifically means that the tape measure will not become longer under the action of tension, thereby ensuring the accuracy of the tape measure measurement.

[0015] The working principle of the present invention is as follows:

[0016] Place the working end of the main ruler on the buccolingual side of one side of the edentulous area, and then use the sliding ruler to make the working end of the sliding ruler on the buccolingual side of the other side of the edentulous area. Finally, adjust the soft ruler to conform to the shape of the alveolar ridge and distribute it on the surface of the keratinized gingiva in the edentulous area. Read the scale: after the sliding ruler is fixed, the fixed section reading of the main ruler is the buccolingual width of the alveolar ridge in the edentulous area, and the reading of the soft ruler is the total width of the alveolar ridge in the edentulous area. That is, the distance between the main ruler and the sliding ruler can measure the buccolingual width of the alveolar ridge, and the soft ruler can measure the overall width of the keratinized gingiva.

[0017] The sliding ruler of the present invention is slidably arranged on the fixed section of the main ruler, and the working ends of the main ruler and the sliding ruler can be respectively clamped on the buccal and lingual sides of the two sides of the edentulous area by adjusting the sliding ruler. At this time, since the soft ruler is made of flexible material, it can conform to the shape of the alveolar ridge and be distributed on the keratinized gingival surface of the edentulous area. The width of the keratinized gingiva on the buccal and lingual sides can be measured by the main ruler and the sliding ruler, and the total width of the alveolar ridge in the edentulous area can be measured by the soft ruler with high accuracy.

[0018] Furthermore, it also includes a counterweight block arranged at the end of the tape measure.

[0019] The setting of the counterweight block ensures that the tape measure has no bending on the surface of the alveolar ridge, thus ensuring the accuracy of the measured value.

[0020] Furthermore, the working end of the sliding ruler and the working end of the main ruler are both provided with outwardly inclined working surfaces, and the tops of the working surfaces can be clamped on the buccal and lingual sides of the edentulous area.

[0021] Further, the initial position of the scale is set at the top of the working surface.

[0022] The above settings are convenient for reading.

[0023] Furthermore, the scale on the sliding ruler is arranged on the inner side thereof, and the scale on the working section of the main ruler is arranged on the inner side of the working section.

[0024] The above settings are convenient for reading.

[0025] Furthermore, the measurement unit is a scale or a color band mark.

[0026] Furthermore, the ribbon marking includes a plurality of ribbons arranged at even intervals, and the length of the ribbons is determined by the spacing between adjacent ribbons.

[0027] The width of the alveolar ridge in the edentulous area can be determined by the color band.

[0028] Furthermore, scales are provided on both the fixed section and the working section of the main ruler.

[0029] Furthermore, the minimum measurement units of the main ruler, sliding ruler and soft ruler are all in mm level.

[0030] mm-level readings can further improve measurement accuracy.

[0031] Furthermore, the soft ruler is made of synthetic fiber polypropylene, and the main ruler and the sliding ruler are made of steel.

[0032] The synthetic fiber polypropylene and steel are both prior art.

[0033] The measuring method based on the edentulous area keratinized gingival width and alveolar ridge width measuring device comprises the following steps:

[0034] S1. Place the working end of the main ruler on the buccal and lingual side of the edentulous area.

[0035] S2. Adjust the sliding ruler so that the working end of the sliding ruler is stuck on the buccal and lingual side of the other side of the edentulous area;

[0036] S3. Adjust the tape measure to conform to the shape of the alveolar ridge and distribute it on the keratinized gingival surface of the edentulous area;

[0037] S4. Read to determine the width of keratinized gingiva and alveolar ridge.

[0038] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0039] 1. The soft ruler part of the present invention can conform to the shape of the alveolar ridge and can accurately measure the width of the keratinized gingiva in the edentulous area, solving the problem that the current measurement of the keratinized gingiva in the oral cavity lacks accurate, efficient measurement means and clear measurement methods.

[0040] 2. The present invention can accurately measure the width of the keratinized gingiva on the buccal and lingual sides of the edentulous area through the main ruler and the sliding ruler, and guide the design of the soft tissue incision for implant surgery accordingly to ensure that a certain amount of keratinized gingiva exists around the implant.

[0041] 3. The present invention can measure the width of keratinized gingiva in edentulous areas with different alveolar ridge widths and alveolar ridge shapes by means of a sliding ruler.

[0042] 4. The present invention can determine the prognosis risk of peri-implant gingivitis in patients by measuring the total width of keratinized gingiva in the surgical area and analyzing its buccal and lingual distribution, determine the necessity of keratinized gingival transplantation in advance, and guide the design of surgical soft tissue incisions.
