Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of subgingival cleaning, and in particular relates to a toothbrush kit for subgingival cleaning. Background Art
[0002] As attached Fig.11 As shown, Fig.11 The current clinician inserts a probe into the periodontal pocket to detect the depth of the periodontal pocket. The gap between the teeth and the gums is called the periodontal pocket, which forms a favorable environment for the growth of specific bacteria. The depth of the periodontal pocket of a normal person is 0-3mm. Since normal people have strong immunity and good oral hygiene, even if there is soft plaque, dental plaque will not cause periodontal disease; however, for patients with periodontitis and people with potential risks of periodontitis (such as smoking, poor oral hygiene, genetic factors, etc.), the depth of their periodontal pockets will be greater than 3mm, so the periodontal pockets need to be cleaned to reduce or treat periodontitis and prevent the occurrence of periodontitis. The current cleaning method is to tilt the bristles of an ordinary toothbrush at a 45° angle to the root of the tooth, so that part of the bristles of the toothbrush can enter the periodontal pocket to clean the gums. However, the cleaning depth of this cleaning method is limited, and excessive force may squeeze the gums, causing gum pain in patients, and in severe cases, it will aggravate the condition. Utility Model Content
[0003] The utility model aims to provide a toothbrush kit for subgingival cleaning which can conveniently clean the gums in the periodontal pocket and can also avoid the user feeling pain.
[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a toothbrush kit for subgingival cleaning, comprising a base and a toothbrush, the base is used to be sleeved on the crown of the tooth and is provided with a matching groove that cooperates with the crown, the end of the base deviating from the matching groove is provided with a limiting groove that penetrates up and down, the limiting groove extends along the circumferential direction of the tooth and is arc-shaped, the toothbrush comprises a handle, a brush rod and a brush head, the brush head has bristles, the brush rod is located between the brush head and the handle, the brush rod passes through the limiting groove, and the limiting groove can limit the swing angle of the brush rod in the front and back direction of the teeth.
[0005] When in use, the operator puts the base on the crown of the tooth, then extends the brush rod of the toothbrush into the limiting groove, and extends the brush head of the toothbrush into the periodontal pocket. The operator holds the handle and moves the toothbrush up and down, so that the brush head can clean the tooth root.
[0006] The sizes of the brush rod and the brush head are similar to the sizes of the end of the existing probe, so that the brush rod can be inserted into the periodontal pocket.
[0007] The diameter of the brush rod is slightly smaller than the width of the limiting groove.
[0008] The limiting groove extends along the circumferential direction of the tooth and is arc-shaped, and its curvature is related to the curvature of the tooth.
[0009] The base sleeve of the present solution is arranged on the crown of the tooth, so that the brush rod can be positioned. When the brush rod swings in the limiting groove along the front-back direction of the tooth, the rod wall of the brush rod will contact the groove walls on the opposite sides of the limiting groove along the front-back direction of the tooth, thereby limiting the swinging angle of the brush rod and preventing the brush rod from squeezing the gums, causing pain to the user and causing gum damage; at the same time, the size of the brush rod in the solution is similar to that of a medical probe, so it can be inserted into the periodontal pocket to clean the teeth.
[0010] Preferably, the limiting groove comprises a narrow section and a wide section from top to bottom, and the width of the wide section gradually increases from top to bottom.
[0011] The limiting groove comprises a narrow section and a wide section, so that when the brush rod is inserted and swung, the brush head has sufficient swing space, thereby increasing the fit between the bristles of the brush head and the teeth.
[0012] Preferably, the end of the base deviating from the limiting groove is provided with a first extension portion extending along the opening direction of the limiting groove, and the first extension portion is used to contact the back side of the tooth; the base is provided with a second extension portion extending downward between the positioning groove and the limiting groove, and the second extension portion is used to contact the front side of the tooth.
[0013] When the base is sleeved on the crown of the tooth, the first extension portion and the second extension portion can contact the back side or the front side of the tooth, so that the base is more stable and the stability of the toothbrush during cleaning is ensured.
[0014] Preferably, the brush rod comprises a thick section and a thin section, the brush head is fixed on the thin section, and the diameter of the thick section is greater than the width of the limiting groove.
[0015] The diameter of the thick section is larger than the width of the limiting groove, which can prevent the brush head from excessively extending into the periodontal pocket.
[0016] Preferably, the thin segment includes a thin segment body and an adjusting rod, the thin segment body is hollow and plug-fitted with the adjusting rod, the brush head is arranged at the end of the adjusting rod, and the length of the adjusting rod extending to the outside of the thin segment body is adjustable.
[0017] The adjusting rod is plugged into the thin segment body, so that the length of the adjusting rod extending outside the thin segment body is adjustable, so that the user can find a suitable length to clean their teeth. The length of the adjusting rod extending outside the thin segment body is adjustable, and a radially extending screw hole can be provided on the thin segment body to clamp the adjusting rod by screwing a bolt; or a protrusion is provided on the adjusting rod, and the protrusion is clamped in the thin segment by a buckle to limit the axial position of the protrusion, etc.
[0018] Preferably, the outer wall of the adjusting rod is provided with protrusions evenly spaced along the axial direction, and the thin segment body is provided with two groups of buckle groups spaced along the axial direction, each group of the buckle groups includes two oppositely arranged buckles, and a space for limiting the axial movement of the protrusion is formed between the two buckle groups, and the distance between the two oppositely arranged buckles is smaller than the width of the protrusion.
[0019] Since the size of the toothbrush for subgingival cleaning is small, the conventional screw fixing method is troublesome. The buckle is used to limit the axial movement of the protrusion, which makes it easier for users to use. The buckle is made of rubber material and can be deformed, so that when the adjustment rod is inserted, the buckle can be deformed to allow the protrusion to pass through. However, when the user does not apply force, the width of the protrusion is greater than the distance between the buckles, so the protrusion cannot pass between the two buckles.
[0020] Preferably, the buckle assembly is located at the opening of the thin segment body.
[0021] It is convenient for operators to observe the engagement between the buckle and the protrusion during insertion.
[0022] Preferably, the thin segment body is provided with an axially extending plug-in hole, the outer wall of the adjusting rod is in contact with the hole wall of the plug-in hole, the inner edge cross-sectional shape of the plug-in hole is non-circular, the thin segment body is provided with a make way hole for making way for the protrusion, the make way hole extends axially and is connected with the plug-in hole, and the buckle group is arranged in the make way hole.
[0023] The plug-in hole is non-circular so that when the adjusting rod is plugged into the thin section, the adjusting rod will not rotate in the circumferential direction.
[0024] Preferably, the bristles of the brush head include first bristles extending laterally, and the lower end of the brush head is provided with second bristles arranged downward and obliquely.
[0025] The second bristles arranged at a downward inclination at the lower end of the brush head can increase the contact depth of the tooth surface and can deeply clean the teeth.
[0026] Preferably, the matching groove is covered with a layer of rubber.
[0027] Since the shapes of different teeth vary greatly, a layer of rubber is provided in the matching groove so that the teeth can be better confined in the matching groove.
[0028] The utility model has the advantages of being able to easily clean the gums in the periodontal pocket and preventing the user from feeling pain. BRIEF DESCRIPTION OF THE DRAWINGS
