Description

Technical Field

[0001] The utility model relates to the technical field of dental medical devices, in particular to a dental resin shaping brush. Background Art

[0002] Tooth defects are common and frequently occurring diseases in the field of stomatology, which can be caused by a variety of factors such as caries, trauma, and wear. In addition to affecting the patient's chewing function and appearance, tooth defects also affect the overall function of the oral system. Clinically, composite resins are often used to fill the patient's mouth directly, which has the advantages of convenience, speed, low price, and positive clinical effects, and is accepted by the majority of patients.

[0003] However, in order to achieve a relatively ideal treatment effect, one of the necessary conditions is that the composite resin material must be in close contact with the teeth. If the composite resin and the teeth are not in close contact, there will be gaps and defects at the contact interface between the two, which will eventually lead to white lines and coloration on the interface, affecting the appearance; the gaps and defects will also cause teeth to become sensitive and painful, and eventually lead to secondary caries, pulpitis, apical periodontitis and other problems, forcing patients to re-reinfill or undergo more complicated root canal treatment, causing greater pain to patients and more loss of money and time.

[0004] Therefore, there is an urgent need for a dental resin shaping brush to solve the problem that the composite resin and the teeth cannot be in close contact with each other during the current direct filling treatment of the teeth in the patient's mouth with composite resin.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] This embodiment provides a dental resin shaping brush, such as Figure 1 As shown, it includes a brush handle 1, a first connecting rod 2, a second connecting rod 3, a posterior teeth area shaping brush mounting seat 4, a posterior teeth area shaping brush 5, anterior teeth area shaping brush mounting seat 6 and anterior teeth area shaping brush 7;

[0025] The two ends of the brush handle 1 are fixedly connected to one end of the first connecting rod 2 and one end of the second connecting rod 3 respectively, and the other end of the first connecting rod 2 is fixedly connected to the posterior teeth area shaping brush mounting seat 4, and the posterior teeth area shaping brush mounting seat 4 is provided with a first mounting hole structure 41, and the posterior teeth area shaping brush 5 is plugged into the posterior teeth area shaping brush mounting seat 4 through the first mounting hole structure 41; specifically, the posterior teeth area shaping brush mounting seat 4 is a cylindrical structure, and the first mounting hole structure 41 includes but is not limited to other regular polyhedron holes such as circular holes or square holes , and the inner wall of the first mounting hole structure 41 is provided with a friction surface; the posterior tooth area shaping brush 5 is a conical nylon brush, and the posterior tooth area shaping brush 5 is provided with a plug-in block 51, the first mounting hole structure 41 is adaptively connected with the plug-in block 51 of the posterior tooth area shaping brush 5, and the outer wall of the plug-in block 51 is provided with a friction surface, and the posterior tooth area shaping brush mounting seat 4 and the posterior tooth area shaping brush 5 are installed or separated through the detachable plug-in of the first mounting hole structure 41 and the plug-in block 51, and the posterior tooth area shaping brush 5 can be repeatedly disinfected and can also be removed and replaced.

[0026] The other end of the second connecting rod 3 is fixedly connected to the anterior teeth area shaping brush mounting seat 6, and the anterior teeth area shaping brush mounting seat 6 is provided with a second mounting hole structure 61, and the anterior teeth area shaping brush 7 is plugged into the anterior teeth area shaping brush mounting seat 6 through the second mounting hole structure 61. Specifically, the anterior teeth area shaping brush mounting seat 6 is a flat cylindrical structure, the inner wall of the second mounting hole structure 61 is provided with a friction surface, and the second mounting hole structure 61 is adaptively connected with the plug-in end 71 of the anterior teeth area shaping brush 7; the anterior teeth area shaping brush 7 is an oblate nylon brush, and the anterior teeth area shaping brush mounting seat 6 and the anterior teeth area shaping brush 7 are installed or separated by the plug-in end 71 of the oblate nylon brush, and the plug-in block 51 and the plug-in end 71 are made of plastic material, and generate retention force with the first mounting hole structure 41 and the second mounting hole structure 61 respectively through friction. The anterior teeth area shaping brush 7 can be repeatedly disinfected and can also be removed and replaced. Since the labial and lingual surfaces of the anterior teeth are mostly flat or small arc-shaped surfaces, flat brushes are easier to operate in the anterior teeth area and are more likely to shape the labial and lingual surfaces of the anterior teeth.

[0027] In this embodiment, the posterior teeth area shaping brush 6 and the anterior teeth area shaping brush 7 are fixedly mounted on the brush handle 1 through the first connecting rod 2, the second connecting rod 3, the posterior teeth area shaping brush mounting seat 4 and the anterior teeth area shaping brush mounting seat 6, so that a pair of brushes can be used not only for posterior teeth area shaping, but also for anterior teeth area shaping. This is economical and practical, and reduces the problem of frequent replacement of anterior and posterior teeth area brushes during tooth restoration and shaping, thus saving teeth shaping time and improving work efficiency. In addition, through the detachable replacement of the posterior teeth area shaping brush 5 and the anterior teeth area shaping brush 7, not only the efficiency of teeth shaping is improved, but also cross infection is effectively avoided.

[0028] In a specific embodiment, the angle between the side wall of the posterior tooth shaping brush 5 and the center line of the posterior tooth shaping brush 5 is 20° to 30°. Since the posterior tooth cusps have a certain inclination angle, the conical nylon brush is easier to operate in the posterior tooth area and easier to shape the posterior tooth occlusal surface.

[0029] In a specific embodiment, the brush handle 1 is made of silicone material and can be sterilized at high temperature and high pressure, and the brush handle 1 is provided with anti-slip grooves 11. The anti-slip grooves 11 are used to prevent the operator from slipping due to slippery gloves or liquids during tooth shaping, which may cause poor tooth shaping effects.

[0030] In a specific embodiment, the first connecting rod 2 and the second connecting rod 3 are made of stainless steel; and one end of the first connecting rod 2 is provided with a bending portion 21, and the bending portion 21 is fixedly connected to the posterior teeth shaping brush mounting seat 4. The bending portion 21 avoids the problem that the posterior teeth shaping brush 5 is not easy to shape the posterior teeth occlusal surface due to the obstruction of tooth tissue.

[0031] Working process: After placing composite resin in the tooth cavity using an existing resin filler and preliminarily shaping it, the dental resin shaping brush in this embodiment is used to repeatedly brush the resin surface from the composite resin toward the tooth along the surface morphology of the tooth, promoting close contact between the resin and the tooth while shaping the surface morphology of the resin, avoiding bubbles, gaps, and defects between the resin and the tooth and inside the resin, preventing edge coloring, micro-leakage, and secondary caries, and at the same time smoothing the resin surface. The handle can be repeatedly disinfected, and the brush can be repeatedly disinfected and replaced after use, effectively avoiding cross infection, and a pair of brushes can be used for both posterior teeth and anterior teeth, which is economical and practical.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
