Description

Technical Field

[0001] This utility model relates to the field of oral medical device technology, specifically to an adjoint point shaping device. Background Technology

[0002] For ease of description, the surfaces of two adjacent teeth that come into contact are called the proximal surfaces of the teeth. These proximal surfaces are typically curved, and the contact between two proximal surfaces is usually a point contact, called the contact point. Normally, two teeth form a close contact relationship, meaning they fit tightly together at the contact point to prevent food from getting stuck between them.

[0003] In dental clinics, when performing direct resin fillings on posterior teeth, after preparing the cavity and placing the molding piece, space wedge, and retaining ring, it is not certain whether the molding piece will be in close contact with the adjacent teeth after using the segmental molding piece or the retaining ring on the molding piece to separate the teeth. Small gaps often exist, which prevent the resin from forming a tight contact relationship after filling, resulting in food impaction and filling failure.

[0004] The above problems urgently need to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide an adjacency point shaping device that can be used to push and extrude a forming sheet during resin filling and resin curing, so that the forming sheet is in close contact with the adjacent tooth, so that the resin forms a better adjacency surface during curing and forms a close adjacency relationship with the adjacent tooth.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An adjacent point shaping device includes: a handle, a guide portion provided on the handle, a working head provided on the guide portion, the working head being a flattened ellipsoid and having an arched notch provided on the working head.

[0008] Optionally, the handle is rod-shaped, with a guide portion at each end of the handle, and each guide portion having a working head. The two guide portions have different guiding directions, and the two working heads have different tilt angles relative to the handle.

[0009] Optionally, the working head includes a working surface, which has an outwardly convex arc in both the horizontal and vertical directions, and the point corresponding to the top of the notch on the working surface is the point with the greatest outward convexity.

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

[0011] Optionally, the first rod portion, the second rod portion, and the third rod portion gradually taper along their extension direction.

[0012] Optionally, the handle is provided with a pinching part, and the pinching part is provided with a plurality of arc-shaped grooves along the circumference.

[0013] Optionally, a connecting portion is provided between the pinching portion and the guiding portion, and the connecting portion is provided with a plurality of annular grooves spaced apart.

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

[0015] In this invention, after preparing the cavity, placing the molding piece, inserting the space wedge and clamping ring, the molding piece is positioned within the gap between two adjacent teeth, C-shaped and covering the sidewall of the restored tooth. The other side of the molding piece contacts the adjacent tooth. After filling the cavity with resin, the contact point shaping device is inserted into the mouth, with the working head 3 placed inside the cavity, notch 31 facing downwards. The working head 3 is used to press the molding piece towards the adjacent tooth, ensuring close contact between the molding piece and the adjacent tooth. Resin filling continues, and some resin enters the notch 31. After the resin hardens, the contact point shaping device is removed. Because the resin that entered the notch 31 hardens along with the resin in the cavity, the hardened resin presses against the molding piece, ensuring close contact even after the device is removed due to the pressure of the hardened resin. Resin filling continues until the cavity is completely filled. The hardened resin then forms a new contact surface, creating a tight connection with the adjacent tooth. Attached Figure Description

Detailed Implementation

[0021] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this invention. Rather, they are merely examples of apparatuses or methods consistent with some aspects of this invention.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the utility model as described in the claims. Additionally, the complete contents of the structures represented in the following embodiments are not limited to those necessary for the solution of the utility model as described in the claims.

[0024] See Figure 1-4 This utility model provides an adjacent point shaping device, including: a handle 1, a guide portion 2 on the handle 1, and a working head 3 on the guide portion 2. The working head 3 is an approximately flattened ellipsoid. The working head 3 has an arched notch 31. See also... 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 compress the forming sheet, the notch 31 faces downward. When the working head 3 is inserted into the mouth by holding the handle 1, since the guide part 2 does not extend in a straight line but has a three-dimensional extended shape, it is easier to insert the working head 3 into the tooth cavity when adjusting the position of the working head 3 by holding the handle 1.

[0025] Procedure: After preparing the cavity, placing the molding piece, inserting the space wedge and clamping ring, the molding piece is positioned within the gap between two adjacent teeth, C-shaped and covering the sidewall of the restored tooth. The inner side of the molding piece forms the sidewall of the cavity, while the outer side contacts the adjacent tooth. After filling the cavity with a portion of resin, insert the contact point shaping device into the mouth, with the working head 3 placed inside the cavity, notch 31 facing downwards. Hold the handle 1 and move the working head 3, pressing the molding piece towards the adjacent tooth to ensure close contact. Continue filling with resin; some resin will enter the notch 31. After the resin hardens, remove the contact point shaping device. Because the resin that entered the notch 31 will harden along with the rest of the resin in the cavity, the hardened resin will press against the molding piece, ensuring close contact even after the device is removed due to the pressure of the hardened resin. Continue filling with resin until the cavity is completely filled. The cured resin will then form a new contact surface, creating a tight connection with the adjacent teeth.

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

[0027] The two guide sections 2 have different directions of extension and different bending angles. Simultaneously, the two working heads 3 also have different tilt angles, allowing them to be used for repairing teeth in different locations and for different types of cavities.

[0028] Optionally, the working head 3 includes a working face 32, see [reference needed] Figure 2-4 The working head 3 can have two working surfaces 32, each with an outwardly convex arc in both the horizontal and vertical directions, so that the working surface 32 approximates or is identical to the outwardly convex shape of the original tooth sidewall. Thus, when the working head 3 extrudes the forming sheet, the working surface 32 will fit against the inner surface of the forming sheet, compressing the inner surface of the forming sheet into a shape more closely resembling the original tooth sidewall. Point A, corresponding to the apex of the notch 31 on the working surface 32, is the point with the greatest outward convexity. The notch 31 has an arched surface; the apex of the arched surface can be understood as a line, and the intersection of this line and the working surface 32 is point A. During resin filling and curing, the cured resin within 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 21, the second rod 22, and the third rod 23 have different extension directions, thus forming a three-dimensional extension shape, so that when the working head 3 is located in the tooth hole, the handle 1 is at an angle that is easy to hold and operate.

[0031] Optionally, the first rod portion 21, the second rod portion 22, and the third rod portion 23 gradually taper along their extension direction.

[0032] Optionally, the handle 1 is provided with a pinching part 4, and the pinching part 4 is provided with a plurality of arc-shaped grooves 41 along the circumference.

[0033] When extruding the formed sheet, a certain amount of force is required. You can place your fingers in the groove 41 to pinch the adjacent shaping device, which makes it easier to pinch and apply force.

[0034] Optionally, a connecting part 5 is provided between the pinching part 4 and the guide part 2, and the connecting part 5 is provided with a plurality of annular grooves 51 spaced apart.

[0035] The connecting part 5 is provided with multiple spaced annular grooves 51, which can increase the toughness and deformation capacity of the adjacent point molder and improve the extrusion effect of the working head 3 on the forming sheet.

[0036] Optionally, the handle 1, guide 2, and working head 3 are integrated into one piece.

[0037] In other words, the adjacent point molding unit can be a one-piece structure, specifically through injection molding. This one-piece structure is simpler to manufacture and offers better mechanical properties.
