TECHNICAL FIELD

[0001] The utility model relates to tooth correction technical field, concretely is a tooth preparation after preparation measurement marking ruler. BACKGROUND

[0002] The interdental clearance measuring ruler is an important tool for measuring the clearance between teeth in the dental field. With the development of oral medicine, the accuracy and efficiency of interdental clearance measurement are increasingly required. Traditional interdental clearance measuring rulers, such as a plug gauge or occlusion paper, can meet the measurement requirements to some extent, but have many shortcomings, such as limited accuracy, hygiene problems, and inconvenience of use. Therefore, various improved interdental clearance measuring rulers have appeared on the market, aiming to improve the accuracy, efficiency, and hygiene safety of measurement.

[0003] The interdental clearance measuring rulers mainly used in the existing market are mainly plug gauge type interdental clearance measuring rulers, which insert metal sheets or plastic sheets of different thicknesses into the interdental clearance to determine the size of the interdental clearance. For example, the existing patent 201621091276.6 discloses a foldable interdental clearance measuring ruler, which includes an interdental clearance measuring ruler, a hand-held handle, and a rotating shaft provided at one end of the hand-held handle. The interdental clearance measuring ruler can rotate along the rotating shaft, and different types of measuring rulers are collected in a foldable manner. The structure has the advantages of simple structure and easy portability, but has limited accuracy and is not easy to clean and disinfect, which poses a risk of cross-infection. The occlusion paper type interdental clearance measuring ruler mainly places the occlusion paper on the occlusal surface and makes the patient perform a biting action. The occlusion paper is then removed and the tooth surface is observed. If the color displayed on the tooth surface is a contact point, the tooth surface can be polished with a needle. For example, the existing patent CN202223361234.8 discloses an occlusion paper convenient for tooth adjacent surface adjustment, which aims to solve the problem that the size of the occlusion paper in the prior art is small and inconvenient to store. Therefore, the occlusion paper is generally used with scissors, and the small size of the occlusion paper makes it easy to fall off the teeth during use. The occlusion paper includes an occlusion paper body, which is connected by a plurality of occlusion papers. The size of the occlusion paper matches the size of the tooth adjacent surface. The occlusion paper is provided with a fixing member for fixing the occlusion paper on the tooth adjacent surface. The occlusion paper is set in a roll shape, and only needs to be taken off from the occlusion paper body when in use. In addition, the fixing member is provided on the occlusion paper, which can fix the occlusion paper on the tooth adjacent surface during use to prevent it from falling off. The structure has the advantages of simple operation and low cost, but has the technical problem of low accuracy. SUMMARY

[0017] In order to make the technical means, creative features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific embodiments.

[0018] As Figure 1 shown, during tooth preparation of the occlusal surface, controlling the preparation thickness of the tooth occlusal surface space is a key step. Traditionally, the doctor can rely on personal experience or use multi-layer occlusal paper to roughly estimate the thickness. However, this method is often not accurate enough.

[0019] Currently, occlusal paper is a commonly used auxiliary tool, which leaves marks after being bitten by the patient. These marks show the occlusal high point of the teeth, which helps the doctor to make subsequent adjustments. However, the occlusal paper cannot directly provide the accurate thickness of the surface space.

[0020] In order to avoid damage due to being too thin during use, the doctor needs to repair the body (such as a full porcelain crown) to have sufficient thickness and strength, so it is required to reserve sufficient surface space during tooth preparation. Therefore, we need a more convenient tooth gap measuring scale for measuring whether the repair space distance between the upper and lower dental arches of the ground teeth in the occlusion state is sufficient during tooth preparation, so that when the doctor installs the repair body on the prepared teeth after the repair body is completed, it can ensure that the occlusion of the repair body is good, the edge is tight, the retention is good, and the shape is normal.

[0021] Therefore, the present application provides a new tooth gap measuring scale 2, as Figure 2 , Figure 3 shown, specifically comprising: a hand handle 1, a gap measuring scale 2 integrally formed with the hand handle 1, a replaceable occlusal pad 3 detachably installed on the gap measuring scale 2, and a marking liquid for marking the occlusal surface of the teeth arranged on the side of the replaceable occlusal pad 3 away from the gap measuring scale 2. It allows the doctor to directly and relatively accurately measure the thickness of the preparation space, thereby greatly simplifying the tooth preparation process and improving the work efficiency. The design provides a tooth gap measuring tool integrating the hand handle 1 and the gap measuring scale 2. Through the detachable replaceable occlusal pad 3, it is not only convenient to clean and reuse, but also realizes direct marking of the occlusal surface of the teeth through the marking liquid on the occlusal pad, improving the accuracy and intuitiveness of the measurement. Using the gap measuring scale 2, the doctor can more conveniently and quickly determine whether the surface space is sufficient, ensuring that the finally produced repair body is not only beautiful but also durable.

[0022] In actual operation, the handle 1 and the gap measuring ruler 2 of this application can be designed as long strips, and the bottom surface of the handle 1 and the gap measuring ruler 2 are preferably located at the same horizontal height. The gap measuring ruler 2 mainly serves to provide a reference occlusal surface for the teeth.

[0023] The replacement bite pad 3 includes: a mounting shell 31 that is bonded to the gap measuring ruler 2. On the side of the mounting shell 31 facing away from the gap measuring ruler 2, a liquid-retaining and moisturizing layer 32, a dust-free paper 33, and a quick-penetrating surface layer 34 are sequentially provided. The replacement bite pad 3 can not only effectively store and release the marking liquid, but also keep it moist. At the same time, the design of the dust-free paper 33 and the quick-penetrating surface layer 34 improves the comfort and cleanliness of use. The mounting shell 31 is made of a breathable bottom film, the liquid-retaining and moisturizing layer 32 is mainly filled with cotton fibers, and the quick-penetrating surface layer 34 on the surface allows the colorant on the bite paper to quickly adhere to the tooth surface when the teeth are biting, and when the teeth are loosened, the excess colorant is locked in the liquid-retaining and moisturizing layer 32 to ensure the dryness and cleanliness of the oral cavity.

[0024] To accommodate different measurement size requirements, the total thickness of the replacement bite pad 3 and the gap measuring ruler 2 is 0.5-2mm.

[0025] To further protect the cleanliness of the measuring ruler, the bottom of the mounting housing 31 is also provided with a dust-free paper 33 for covering and storing the gap measuring ruler 2.

[0026] The rigidity of the measuring ruler is ensured by limiting the thickness of the gap measuring ruler 2, which is 0.08-0.2 mm.

[0027] The adhesive 4 provided on the mounting housing 31 is preferably any one of Lohmann tape, skin adhesive, or silicone-based adhesive. This choice of adhesive 4 ensures that the replacement bite pad 3 can be stably attached to the measuring scale, preventing it from falling off or shifting, thereby guaranteeing the accuracy and reliability of the measurement. At the same time, these adhesive materials are skin-friendly, improving the operational safety of the device.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
