Description

Technical Field

[0001] The utility model relates to the field of medical instruments, and in particular comprises a front teeth forming sheet. Background Art

[0002] The adjacent surfaces of teeth are prone to caries. In clinical treatment, filling and restoration are often required, and molded sheets are widely used in the restoration process.

[0003] The forming sheet conforms to the contours of the tooth's adjacent surfaces, pressurizing and shaping the filling material. However, to ensure a quality installation, it must be placed close to the gums. However, forming sheets are generally thin. Consequently, the gum-facing end of existing forming sheets can easily penetrate into the gingival sulcus, damaging the epithelium and causing harm to the patient. Furthermore, this damage can cause bleeding within the gingival sulcus, adversely affecting subsequent resin bonding and creating hygiene and operational challenges.

[0004] Therefore, there is an urgent need for a forming sheet to solve the above problems existing in the treatment process of anterior teeth. Utility Model Content

[0005] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a front teeth shaping sheet.

[0006] The two sides of the anterior teeth forming sheet in the width direction are bent toward the same surface to form an arc surface for fitting the adjacent surfaces of the anterior teeth.

[0007] The front teeth forming piece has a middle concave arc in the middle of one end facing the gum, and two lower protrusions are respectively provided on both sides of the middle concave arc. The front teeth forming piece is inserted into the gap between the front teeth, and the middle concave arc matches the contour of the gingival papilla between the front teeth.

[0008] Preferably, both sides of the anterior teeth forming piece in the width direction are inclined toward the inclination direction of the anterior teeth.

[0009] Preferably, the lower protrusions on both sides and the concave arc in the middle of the front teeth forming piece are both circular arcs and are connected in an arc shape.

[0010] Preferably, the height of the anterior teeth forming piece is greater than the height of the anterior teeth crown, and the width of the anterior teeth forming piece is greater than the thickness of the anterior teeth.

[0011] Preferably, the front teeth forming piece is curved in the height direction, and the curvature is the same as the curvature in the width direction, so as to fit the contour curve of the front teeth side in the height direction.

[0012] The beneficial effects of the utility model are:

[0013] 1) The utility model provides a front teeth forming piece with two side downward protrusions and a middle concave arc on one end facing the gums, so that when the front teeth forming piece is inserted between the front teeth, the protruding gingival papilla of the gums is not damaged while ensuring the normal function of the front teeth forming piece, thereby improving safety and comfort and avoiding the problem of difficult treatment caused by bleeding gums.

[0014] 2) The utility model sets the front teeth forming piece as an arc surface, so that it fits the side contour of the front teeth that need to be covered, and the inclination angle of the front teeth forming piece and the front teeth match, which better assists clinical treatment.

[0018] The present invention will be further described below with reference to the following embodiments. The following embodiments are provided solely to facilitate understanding of the present invention. It should be noted that, within the scope of the present invention, modifications may be made by a person skilled in the art without departing from the principles of the present invention. Such improvements and modifications are also within the scope of the claims of the present invention.

[0019] As an example, Figure 1 and Figure 2 As shown, this anterior teeth forming sheet has two sides of the anterior teeth forming sheet 1 in the width direction bent toward the same plane to form an arc surface, which is used to fit the adjacent surfaces of the anterior teeth; the anterior teeth forming sheet 1 is bent in the height direction, and the bending direction is the same as the bending in the width direction, which is used to fit the contour curve of the side edges of the anterior teeth in the height direction.

[0020] The front teeth forming piece 1 is provided with a central concave arc 3 in the middle of one end facing the gums, and two lower protrusions 2 are provided on both sides of the central concave arc 3. The front teeth forming piece 1 is inserted into the gap between the front teeth, and the central concave arc 3 matches the contour of the gingival papilla 6 between the front teeth.

[0021] The schematic diagram of the front teeth forming piece 1 inserted between the front teeth is as follows Figure 2As shown, the anterior teeth on one side of the curved surface of the anterior teeth forming sheet 1 are the inner anterior teeth 4, and the anterior teeth on the other side are the outer anterior teeth 5. The anterior teeth forming sheet 1 is inserted along the gap between the inner anterior teeth 4 and the outer anterior teeth 5 until the adjacent anterior teeth are separated, thereby wrapping the adjacent surface of the inner anterior teeth 4. At this time, the protruding gingival papilla 6 between the inner anterior teeth 4 and the outer anterior teeth 5 is located in the middle concave arc 3, so that the gingival papilla 6 and the gingival sulcus will not be scratched by the edge of the anterior teeth forming sheet 1. The lower protrusions 2 on both sides are respectively stuck in the inner and outer sides of the oral cavity to ensure that the position of the anterior teeth forming sheet 1 is fixed.

[0022] Since the cross-section of the crown of the human front teeth is tilted to a certain extent, in this embodiment, both sides of the front teeth forming sheet 1 in the width direction are tilted toward the inclination direction of the front teeth, thereby improving the fit between the front teeth forming sheet 1 and the adjacent surfaces of the front teeth.

[0023] The lower protrusions 2 on both sides and the concave arc 3 in the middle of the front teeth forming piece 1 are all arcs and connected in an arc shape, so that the outer contour of the front teeth forming piece 1 is rounded as a whole and is not likely to cause damage to the patient.

[0024] Since the intergingival papilla 6 between the teeth is not a single protruding structure, but a state in which a gingival valley is sandwiched between two intergingival papillae 6, the specific shape of the central concave arc 3 can also be set to match the contours of the intergingival papilla 6 and the gingival valley, further improving its fit with the adjacent surfaces of the anterior teeth.

[0025] The height of the front teeth forming piece 1 is greater than the height of the tooth crown, that is, the height of the front teeth exposed outside the gums, and the width of the front teeth forming piece 1 is greater than the thickness of the front teeth crown.
