Description

Technical Field

[0001] The present invention relates to the technical field of oral medical instruments, and in particular to an adjacency point shaper. Background Art

[0002] For the sake of convenience, the surface where two adjacent teeth touch is called the adjacent surface of the teeth. The adjacent surface of the teeth is usually arc-shaped, and the contact between the two adjacent surfaces is usually point contact, which is called the adjacent point. Under normal circumstances, the two teeth form a close adjacent relationship, that is, the two teeth fit closely at the adjacent point, so as to ensure that food will not be stuck in the gap between the teeth.

[0003] When performing direct resin filling of posterior teeth in dental clinics, after preparing the hole and placing the forming sheet, spacing wedge and clamping ring, it is impossible to be sure whether the forming sheet is in close contact with the adjacent teeth after using the segmented forming sheet or the clamping ring on the ring-shaped forming sheet to separate the teeth. There are often small gaps that prevent the resin from forming a close adjacent relationship, resulting in food impaction and filling failure.

[0004] The above problems urgently need to be solved by those skilled in the art. Summary of the invention

[0005] The object of the present invention is to provide an adjacent point shaper, which can be used to push the extruded forming sheet when filling and curing the resin, so that the forming sheet is in close contact with the adjacent teeth, so that the resin forms a better adjacent surface when curing and forms a close adjacent relationship with the adjacent teeth.

[0006] In order to achieve the above object, the present invention adopts the following technical scheme:

[0007] A proximal point shaper comprises a handle, a guide portion is arranged on the handle, a working head is arranged on the guide portion, the working head is in the shape of an oblate ellipsoid, and an arched notch is arranged on the working head.

[0008] Optionally, the handle is rod-shaped, and a guide portion is provided at each end of the handle, each guide portion is provided with a working head, the two guide portions have different guides, and the two working heads have different inclination angles relative to the handle.

[0009] Optionally, the working head comprises a working surface, the working surface has a convex curvature in both the horizontal direction and the vertical direction, and the point on the working surface corresponding to the top end of the notch is the most convex point.

[0010] Optionally, the guide portion includes a first rod portion, a second rod portion and a third rod portion, the first rod portion and the second rod portion are smoothly transitionally connected and have different extension directions, and the second rod portion and the third rod portion are smoothly transitionally connected and have different extension directions.

[0011] Optionally, the first rod portion, the second rod portion and the third rod portion gradually become thinner along their extension directions.

[0012] Optionally, a gripping portion is provided on the handle, and the gripping portion is provided with a plurality of arc-shaped grooves along the circumferential direction.

[0013] Optionally, a connecting portion is provided between the gripping portion and the guiding portion, and the connecting portion is provided with a plurality of annular grooves arranged at intervals.

[0014] Optionally, the handle, the guide portion and the working head are an integrated structure.

[0015] In the technical solution of the present invention, after preparing the tooth hole, placing the forming sheet, inserting the gap wedge and clamping the clamping ring, the forming sheet is located in the tooth gap between two adjacent teeth, and is C-shaped and wrapped on the side wall of the repaired tooth. The other side of the forming sheet is in contact with the adjacent tooth of the repaired tooth. After a portion of resin is filled into the tooth hole. The adjacent point shaping device is inserted into the mouth, the working head 3 is placed into the tooth hole, and the notch 31 of the working head is facing downward. The forming sheet is squeezed toward the adjacent tooth with the working head 3 so that the forming sheet is in close contact with the adjacent tooth. At this time, the resin is continued to be filled, and a part of the resin will enter the notch 31. After the resin is solidified, the adjacent point shaping device is taken out. Since the part of the resin that enters the notch 31 will solidify together with the other parts of the resin in the tooth hole, the solidified resin will hold up the forming sheet, so that even after the adjacent point shaping device is taken out, the forming sheet is squeezed by the solidified resin and is still in close contact with the adjacent tooth. At this time, the resin is continued to be filled until the tooth hole is completely filled. Then the solidified resin will form a new adjacent surface and form a close connection relationship with the adjacent tooth. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are only examples of devices or methods consistent with some aspects of the present invention.

[0022] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0023] The following is an explanation of the embodiments with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the invention described in the claims. In addition, the entire contents of the configurations shown in the following embodiments are not limited to the solutions required as the invention described in the claims.

[0024] See also Figure 1-4 The present invention provides an adjacent point shaping device, comprising: a handle 1, a guide portion 2 is provided on the handle 1, a working head 3 is provided on the guide portion 2, and the working head 3 is in the shape of an oblate ellipsoid, which means that the working head 3 is approximately in the shape of an oblate ellipsoid. An arched notch 31 is provided on the working head 3. Figure 2 The lower end of the working head 3 is provided with a notch 31. When the working head 3 is inserted into the mouth to extrude the forming sheet, the notch 31 is downward. When the working head 3 is inserted into the mouth by holding the handle 1, since the guide portion 2 does not extend in a straight line but has a three-dimensional extension shape, the working head 3 can be placed into the tooth cavity more conveniently when the position of the working head 3 is adjusted by holding the handle 1.

[0025] Usage process: After preparing the tooth hole, placing the forming sheet, inserting the gap wedge and clamping the clamping ring, the forming sheet is located in the gap between two adjacent teeth and is C-shaped and wrapped on the side wall of the restored tooth. The inner side of the forming sheet forms the side wall of the tooth hole, and the outer side is in contact with the adjacent tooth of the restored tooth. After filling a part of the resin into the tooth hole, extend the adjacent point shaper into the mouth, put the working head 3 into the tooth hole, and the notch 31 of the working head 3 is facing downward. Hold the handle 1 and move the working head 3 so that the working head 3 squeezes the forming sheet in the direction of the adjacent tooth so that the forming sheet is in close contact with the adjacent tooth. At this time, continue to fill the resin, and part of the resin will enter the notch 31. After the resin is solidified, take out the adjacent point shaper. Since the part of the resin that enters the notch 31 will solidify together with the other parts of the resin in the tooth hole, the solidified resin will hold the forming sheet, so that even after the adjacent point shaper is taken out, the forming sheet is squeezed by the solidified resin and is still in close contact with the adjacent tooth. At this time, continue to fill the resin to fill the tooth hole completely. The solidified resin will form a new adjacent surface and form a close connection with the adjacent teeth.

[0026] Optionally, the handle 1 is rod-shaped, and a guide portion 2 is provided at each end of the handle 1. Each guide portion 2 is provided with a working head 3. The two guide portions 2 have different guides, and the two working heads 3 have different inclination angles relative to the handle 1.

[0027] The two guide parts 2 have different guides, that is, the two guide parts 2 have different extension directions and different bending angles. At the same time, the two working heads 3 also have different inclination angles, so that the two working heads 3 can be suitable for repairing teeth in different positions and different types of tooth cavities.

[0028] Optionally, the working head 3 comprises a working surface 32, see Figure 2-4 The working head 3 can have two working surfaces 32, and the working surfaces 32 have convex curvatures in both the horizontal and vertical directions, so that the working surfaces 32 are similar to or identical to the convex shapes of the original side walls of the teeth. In this way, when the working head 3 extrude the forming sheet, the working surface 32 will fit with the inner side surface of the forming sheet, and extrude the inner side surface of the forming sheet into a shape that is more similar to the original side walls of the teeth. Point A corresponding to the top of the notch 31 on the working surface 32 is the most convex point. The notch 31 has an arched surface, and the top of the arched surface can be understood as a line, and the intersection of this line and the working surface 32 is point A. When the resin is filled and cured, the cured resin in the notch 31 forms an adjacent point at point A.

[0029] Optionally, the guide portion 2 includes a first rod portion 21, a second rod portion 22 and a third rod portion 23, the first rod portion 21 and the second rod portion 22 are smoothly connected and have different extension directions, and the second rod portion 22 and the third rod portion 23 are smoothly connected and have different extension directions.

[0030] The first rod portion 21 , the second rod portion 22 and the third rod portion 23 have different extension directions, thereby forming a three-dimensional extension shape, so that when the working head 3 is located in the tooth cavity, the handle 1 is at an angle that is convenient for gripping and operation.

[0031] Optionally, the first rod portion 21 , the second rod portion 22 and the third rod portion 23 gradually become thinner along their extending directions.

[0032] Optionally, a gripping portion 4 is provided on the handle 1 , and a plurality of arc-shaped grooves 41 are provided on the gripping portion 4 along the circumferential direction.

[0033] When squeezing the forming sheet, a certain amount of force is required, and the adjacent point shaper can be pinched by placing fingers in the groove 41 to facilitate pinching and exerting force.

[0034] Optionally, a connecting portion 5 is provided between the gripping portion 4 and the guiding portion 2 , and the connecting portion 5 is provided with a plurality of annular grooves 51 arranged at intervals.

[0035] The connecting portion 5 is provided with a plurality of annular grooves 51 arranged at intervals, which can increase the toughness and deformation capacity of the adjacent point shaper and improve the extrusion effect of the working head 3 on the forming sheet.

[0036] Optionally, the handle 1, the guide portion 2 and the working head 3 are an integrated structure.

[0037] That is, the adjacent point shaper can be an integrated structure, and can be specifically formed by injection molding. The integrated structure is simple to manufacture and has good mechanical properties.
