Technical Field

[0001] The utility model relates to the technical field of oral medical devices, and particularly relates to a filling and forming device for adjacent tooth defects. Background Art

[0002] In the clinical operation of filling adjacent caries, the usual operation is as follows: First, insert a matrix band between the carious tooth and the adjacent tooth, then clamp the matrix band and the carious tooth together with a matrix band retainer, and then insert a wedge into the gap between the carious tooth and the adjacent tooth, so that the matrix band adheres to the adjacent caries of the carious tooth under the extrusion of the matrix band retainer and the wedge. Finally, fill the adjacent caries. In this way, a relatively large number of auxiliary tools are required during the fixing process of the matrix band, and the fixing operation is cumbersome, so that the filling operation of adjacent caries is time-consuming and likely to cause discomfort to the patient; especially for defects that simultaneously involve the adjacent surfaces and the lingual sides of the mandibular anterior teeth, the traditional matrix band cannot fit well with the tooth surface, and it is relatively difficult to shape when filling with nanocomposite resin, which greatly affects the treatment efficiency and effect.

[0003] The patent with the publication number CN218792541U discloses a dental filling auxiliary component and a forming arc piece. Among them, the dental filling auxiliary component includes a rubber dam clamp and a bendable and deformable forming arc piece. The rubber dam clamp is used to clamp both sides of the tooth to be filled; the forming arc piece includes an isolation part and two insertion parts. The two insertion parts are respectively arranged at both ends of the isolation part. The isolation part is used to be inserted into the first gap between the tooth to be filled and the adjacent tooth to fit the tooth to be filled, and the two insertion parts are inserted into the second gap between the rubber dam clamp and the tooth to be filled.

[0029] Embodiment

[0030] In the embodiment of the present application, please refer to Figure 1 and Figure 2 Figure 1 It is a schematic structural diagram of an occlusal surface dental defect filling and forming device provided by an embodiment of the present application, Figure 2 ​It is a top view of an occlusal dental defect filling and forming device provided by an embodiment of the present application; the present application provides an occlusal dental defect filling and forming device, including a fixed former 1 and two locking devices 2; the fixed former 1 is in an "x" shape and is vertically arranged at the interdental space; the two locking devices 2 are respectively arranged on the buccal side and the lingual side of the fixed former 1; the locking device 2 presses against the fixed former 1 to fit and fix with the tooth surface, so as to repair the occlusal root caries on the tooth body 3.

[0031] The above-mentioned fixed former 1 is in an "x" shape from an overlooking perspective, conforming to the structure between two adjacent teeth, being able to fit the tooth surface more closely, and facilitating the locking device 2 to fix the fixed former 1.

[0032] In an embodiment of the present application, please refer to Figure 3 and Figure 4 , Figure 3 is a schematic structural diagram of the fixed former provided by an embodiment of the present application, Figure 4 is a schematic structural diagram of the fixed former from another perspective provided by an embodiment of the present application; the fixed former 1 includes a forming arc piece 11 and a fixing arc piece 12; both the fixing arc piece 12 and the forming arc piece 11 are made of micro-elastic materials, which are convenient for the locking device 2 to apply force. In the natural state, they are both semi-circular arc-shaped, and the length and the radian of the semi-circular arc should match the affected teeth of the patient. The height is not lower than the enamel part, and the thickness is 0.1 mm, which is for adapting to people with smaller interdental spaces; the inner arc surface of the forming arc piece 11 fits with the side of the affected tooth close to the root caries; the fixing arc piece 12 fits with the adjacent tooth close to the root caries on the side of the affected tooth, and its inner arc surface fits with the side of the adjacent tooth close to the root caries; one end of the locking device 2 is connected to the fixing arc piece 12, and the other end is connected to the forming arc piece 11.

[0033] It should be noted that since there is a lingual fossa on the tooth body on the lingual side, those skilled in the art should adjust the radian of the forming arc piece 11 according to the actual situation to make it fit the tooth body completely.

[0034] In order to enhance the stability of the fixed former 1, a fixing part 13 is arranged between the fixing arc piece 12 and the forming arc piece 11; the outer arc surfaces of the fixing arc piece 12 and the forming arc piece 11 are vertically attached at the interdental space, and this attachment part is welded or bonded, which is the fixing part 13. For adapting to people with larger interdental spaces, the thickness of the fixing part 13 can be increased.

[0035] The above-mentioned forming arc piece 11 is adhesively connected or clamped with a sealing edge 111 on the side close to the gingiva. The forming arc piece 11 and the sealing edge 111 are integrally formed. The height of the sealing edge 111 is 1 mm, and the thickness and length match those of the forming arc piece 11. The sealing edge 111 made of silica gel material is embedded in the gingiva, avoiding damage to the gingiva while closely adhering to the tooth root and preventing excess filling material from getting under the gingiva.

[0036] A number of filling and curing openings 112 are provided on both the buccal and lingual sides of the formed arc piece 11. The present application does not limit the number of filling and curing openings 112, and those skilled in the art should make adjustments according to actual needs. The filling and curing openings 112 are located above the sealing edge 111 and are arranged vertically. The filling and curing openings 112 can be holes of any shape, preferably round holes, which are convenient for matching with the filler, and the diameter should be adapted to the caliber of the filler. In the early stage, a liquefied colloidal material, such as nano-flowing resin, is filled through the filling and curing openings 112. The colloidal material needs to be injected in layers. Every time 1 mm is injected, it is necessary to irradiate the colloidal material with a light curing lamp through the filling and curing openings 112 to harden the colloidal material.

[0037] A notch 113 is horizontally provided above each of the filling and curing openings 112 (i.e., in the middle of the buccal and lingual sides of the formed arc piece 11). The length of the notch 113 is about one-third of the length of the formed arc piece 11. One end of the notch 113 starts from the edge of the formed arc piece 11 and extends towards the fixing part 13 for filling the solid resin material.

[0038] Exemplarily, when filling the solid resin material, first widen the distance between the upper half of the formed arc piece 11 divided by the notch 113 and the tooth surface of the affected tooth. After the solid resin material is filled, attach and fix the upper half to the tooth surface of the affected tooth.

[0039] A protective edge 121 is bonded or clamped to the side of the fixed arc piece 12 close to the gum. The height of the protective edge 121 is 1 mm, and the thickness and length are matched with the fixed arc piece 12. The protective edge 121 made of silica gel is embedded in the gum to prevent the fixed arc piece 12 from damaging the gum.

[0040] A number of limiting grooves 122 for cooperating with the locking device 2 are provided in the middle of the buccal and lingual sides of the fixed arc piece 12. The present application does not limit the number of limiting grooves 122, and those skilled in the art should make adjustments according to actual needs. The limiting grooves 122 are arranged horizontally and can be holes of any shape, preferably vertically elliptical holes, which can shorten the distance between the limiting grooves 122 while being beautiful, so as to realize more gear adjustments of the locking device 2, be more applicable to a wider range of people, and have stronger practicability.

[0041] In the embodiment of the present application, please refer to Figure 5 , Figure 5 is a schematic structural diagram of the locking device provided by the embodiment of the present application; the locking device 2 includes a fixing member 21, a torsion spring 22 and a clamping block 23; the fixing member 21 is provided on the formed arc piece 11; one end of the torsion spring 22 is connected to the fixing member 21, and the other end is connected to the clamping block 23; wherein, the clamping block 23 is tightly connected to the fixed arc piece 12 through the limiting groove 122.

[0042] The fixing member 21 is preferably cylindrical, arranged perpendicular to the outer side of the formed arc piece 11, and placed above the notch 113. Its bottom surface is welded or bonded to the outer side of the formed arc piece 11 to fix the locking device 2 to the formed arc piece 11.

[0043] One end of a torsion spring 22 is welded or clamped to the side of the fixing member 21, and a clamping block 23 is welded or clamped to the other end of the torsion spring 22. Because the device is small in size, a single-turn torsion spring 22 is selected. The torsion spring 22 is a common prior art and will not be described in detail here.

[0044] The clamping block 23 is preferably in a triangular block shape so as to better engage with the limiting groove 122 .

[0045] In summary, the present application provides a device for filling and molding proximal tooth defects, including a fixed former 1 and a locking device 2; the fixed former 1 is in an "x" shape, conforming to the structure between two adjacent teeth, can better fit the tooth surface, and is vertically arranged in the tooth gap; the locking device 2 is respectively arranged on the buccal and lingual sides of the fixed former 1; the locking device 2 controls the fixed former 1 to fit and fix the tooth surface so as to repair proximal root caries.

[0046] Operation process: Grind off the carious tissue and prepare a hole, apply an etchant on the hole, rinse it with water after 20 seconds, and blow it dry with an air gun; place the fixing part 13 vertically at the tooth gap, insert the sealing edge 111 and the protective edge 121 into the gums, and at the same time, fit the formed arc piece 11 with the affected tooth, and fit the fixed arc piece 12 with the adjacent tooth on the carious side of the root surface of the affected tooth; apply adhesive (liquid) in the hole, then blow it gently through the filling and curing port 112 and illuminate it with a light curing lamp for 20 seconds; then fill the flowing resin material and the paste resin material in turn.

[0047] When filling the flowing resin material, first press the torsion spring 22 toward the tooth side to fix the clamping block 23 in the appropriate limiting groove 122, while making the forming arc piece 11 and the fixed arc piece 12 completely fit with the tooth surface, and inject the flowing resin through the filling and curing port 112;

[0048] Fill with paste resin material, first pull out the upper part of the forming arc piece 11, and after filling it with resin material, press the torsion spring 22 to fix the block 23 in a suitable limit groove 122, and use a curing lamp after the forming arc piece 11 and the fixed arc piece 12 are completely fitted with the tooth surface.

[0049] When disassembly is required, use tweezers or other tools to reach into the coil of the torsion spring 22 and pull it toward one side of the arc piece 11 to make the clamping block 23 escape from the limiting groove 122, and then take out the entire device.

[0050] Application Process

[0051] Dental matrix bands are medical instruments commonly used in dental treatment and diagnosis. Existing dental matrix bands are strip-shaped and lentil-shaped. When the strip-shaped matrix band is used for dental interdental spaces, it needs to be fixed on the teeth by turning a wrench to isolate the interdental space. Its disadvantages are as follows: the operation is complex; when the doctor turns the matrix band in the patient's oral cavity by hand, it causes strong discomfort to the patient; inappropriate operation force is also likely to cause injury to the patient; it is unhygienic; it is relatively easy to be damaged during use, resulting in waste; it cannot fit well with the tooth surface; sometimes it is necessary to overly enlarge the cavity to use it, causing tooth damage. The lentil-shaped dental matrix band is composed of multiple components, all of which are separate parts and must be used together with several accessories to play the role of isolation. It needs to be used in combination with a fixing ring, a lentil-shaped matrix band, a fastening needle, and forceps. Its disadvantages are as follows: there are many accessories, the operation is complex, and multiple accessories need to be used in combination; the technical requirements for doctors are high; the damage rate is high during repeated use. Due to the inability to fit with the tooth surface, the above two types of matrix bands are not suitable for lingual, proximal, and root surface caries of mandibular anterior teeth; and the plastic matrix band cannot be fixed and is prone to deformation, so it cannot better restore the tooth surface contour.

[0052] Therefore, the present application provides an occlusal and proximal dental defect filling and forming device. First, grind away the carious tissue and prepare the cavity. Then, before filling, an etchant needs to be applied to the cavity, rinsed with water after 20 seconds, and dried with an air gun head; the fixing former 1 with an "x" - shaped design is used to fit with the tooth body 3. When installing, press the locking device 2 inward to fix the device and then fill the filling material;

[0053] Apply an adhesive (liquid) to the cavity, then gently blow through the filling curing port 112 and irradiate with a light - curing lamp for 20 seconds. Next, flowable resin and paste - like resin are filled successively. When disassembly is required, use tools such as forceps to loosen the torsion spring 22 and remove the entire device.

[0054] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
