Description

Technical Field

[0001] The present disclosure relates to the technical field of dental devices, and in particular to a molding sheet for treating proximal caries. Background Art

[0002] Proximal caries of anterior teeth is a very common dental disease, and it is common for the proximal surfaces on both sides of the same interproximal space to be carious at the same time. At the same time, the requirements for aesthetic shape and color of anterior teeth filling are very high. At present, the commonly used restoration method in clinical practice is mainly resin restoration, and proximal spacers must be used as an auxiliary to restore a better proximal relationship, thereby achieving an ideal restoration effect.

[0003] In clinical practice, when repairing caries on the interproximal surfaces of adjacent anterior teeth, plastic sheets are usually used as interproximal spacers. After cleaning the caries on the two anterior teeth, resin is first used to fill the caries on one tooth and then solidified. The plastic sheet is inserted between the two adjacent anterior teeth, and then resin is used to fill the caries on the other tooth and then solidified. The plastic sheet separates the resin on the interproximal surfaces of the two anterior teeth. Finally, the plastic sheet is removed to form a gap structure between the interproximal surfaces of the two adjacent anterior teeth that is close to that between natural teeth.

[0004] However, when the caries area on the adjacent surfaces of two adjacent front teeth is large, the caries will usually extend to the lingual side of the adjacent surfaces of the two adjacent front teeth. The plastic sheet cannot support and shape the resin on the lingual side of the two adjacent front teeth. The resin will flow and accumulate under its own gravity during filling, resulting in abnormal shape of the resin on the front teeth after solidification. Multiple drilling and grinding adjustments are required to ensure that the resin on the lingual side of the front teeth does not affect the patient's bite, affecting the treatment efficiency and increasing the treatment steps and time.

[0029] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0031] Reference Figures 1 to 4 As shown, the embodiment of the present disclosure provides a molding sheet for proximal caries, including a jaw plate group 2 and a spacer 1; the spacer 1 is connected to one side of the jaw plate group 2, and the spacer 1 is located in the middle area of ​​the jaw plate group 2, the spacer 1 extends in the direction away from the jaw plate group 2, and a molding surface 211 is formed on the side of the jaw plate group 2 facing the spacer 1, part of the molding surface 211 is used for bonding and connecting with the lingual sides of two adjacent front teeth 3, part of the molding surface 211 is used for bearing the resin on the front teeth 3, the spacer 1 is used to be arranged in the gap between the two adjacent front teeth 3, and part of the spacer 1 is used to contact with the resin on the front teeth 3.

[0032] Specifically, the above-mentioned jaw plate group 2 can be selected to include a plate body structure, a spacer 1 is arranged on one side of the plate body structure, the spacer 1 is arranged in the middle position of the plate body structure, the spacer 1 extends in the direction away from the plate body structure, the spacer 1 is arranged between two adjacent front teeth 3, and the plate body structure is arranged on the lingual side of the two front teeth 3 and fits with the lingual side of the front teeth 3.

[0033] Of course, it includes two abutment plates 21, the two abutment plates 21 are arranged at an interval, and the two abutment plates 21 are in the same plane, the spacer 1 is arranged on one side of the plane where the two abutment plates 21 are located, one end of the spacer 1 is connected to the two abutment plates 21, and the other end extends in a direction away from the two abutment plates 21, so that the spacer 1 is arranged between the two front teeth 3, and the two abutment plates 21 are located on the lingual side of the front teeth 3.

[0034] An adhesive resin may be optionally provided on one side of the jaw plate group 2 facing the spacer 1 to form a shaping surface 211 on the jaw plate group 2 facing the spacer 1, and the shaping surface 211 is bonded to the side of the front teeth 3 using the adhesive resin. Of course, it is also possible to provide a glue layer formed by medical glue on one side of the jaw plate group 2 facing the spacer 1 to form the shaping surface 211, so that the shaping surface 211 can be bonded to the lingual side of the front teeth 3.

[0035] There is a gap between two adjacent front teeth 3 in the patient's oral cavity. The side of the front teeth 3 facing the patient's lips is the labial side of the front teeth 3, and the side of the front teeth 3 facing the patient's tongue is the lingual side of the front teeth 3. Caries of the front teeth 3 will occur on the side where the two adjacent front teeth 3 are close to each other. After the carious part of the front teeth 3 is removed, a space 31 to be filled will be formed. The resin is filled into the space 31 to be filled and cured, thereby completing the operation of treating caries. When the carious area is large, a larger volume of the tooth body of the front teeth 3 needs to be removed, and the space to be filled on the front teeth 3 will expand to the lingual side and the labial side of the front teeth 3, resulting in gaps in the space 31 to be filled on both the lingual side and the labial side of the front teeth 3. During treatment, the patient lies on his back with the lingual and labial sides of the front teeth 3 arranged in the vertical direction. After the resin is filled into the space 31 to be filled, since the resin has not yet solidified and is fluid, the resin in the space 31 to be filled will move toward the lingual side of the front teeth 3, resulting in an abnormal shape after the resin is solidified. Multiple drilling and grinding adjustments are required to make the shape of the front teeth 3 filled with resin adapt to the patient's oral occlusion.

[0036] The molding sheet for proximal caries provided in the embodiment of the present invention is provided with a spacer 1 and a jaw plate group 2. The spacer 1 is inserted between two adjacent front teeth 3, so that the resins on the sides of the two adjacent front teeth 3 that are close to each other will not contact each other, thereby preventing the resins on the two front teeth 3 from being connected to each other during solidification and failing to form a tooth gap; part of the jaw plate group 2 close to the tooth gap position of the front teeth 3 forms a bearing structure for the resin in the space 31 to be filled on the lingual side of the front teeth 3, and the remaining distributed jaw plate group 2 can be bonded to the lingual side of the front teeth 3, so that the jaw plate group 2 is stably arranged on the lingual side of the front teeth; the jaw plate group 2 and the spacer 1 cooperate with each other to have a plastic effect on the resin in the space 31 to be filled of the front teeth 3, thereby preventing the resin from flowing in the space 31 to be filled and forming large protrusions on the front teeth 3, so that the shape of the resin in the space 31 to be filled after solidification is adapted to the shape of the front teeth 3 itself, thereby reducing the subsequent operation of adjusting the shape of the front teeth 3 filled with resin, and improving the convenience of operation in treating the front teeth 3 with proximal caries.

[0037] When the molding sheet for proximal caries provided by the embodiment of the present disclosure is used specifically, the carious area of ​​the front teeth 3 is removed to form a space 31 to be filled, the shaping surface 211 of the jaw plate group 2 is bonded to one surface of the lingual side of the two adjacent front teeth 3, and the resin is filled into the space 31 to be filled. The resin contacts the jaw plate group 2 and the spacer 1 in the space 31 to be filled, so that the spacer 1 and the jaw plate group 2 have a plastic effect on the resin in the space 31 to be filled, and the resin is cured; after the resin is cured, the jaw plate group 2 is separated from the front teeth 3, and the spacer 1 is pulled out from the gap between the two adjacent front teeth 3, and the edges and corners of the cured resin are ground into an arc shape using a dental grinder to improve the patient's comfort after treatment.

[0038] The molding sheet for proximal caries provided by the embodiment of the present disclosure includes a jaw plate group 2 and a spacer 1; the spacer 1 is connected to one side of the jaw plate group 2, and the spacer 1 is located in the middle area of ​​the jaw plate group 2, so that when the spacer 1 is set in the gap between the two front teeth 3, the jaw plate group 2 is respectively opposite to the lingual sides of the two front teeth 3, and the spacer 1 extends in a direction away from the jaw plate group 2. A molding surface 211 is formed on one side of the jaw plate group 2 facing the spacer 1, and part of the molding surface 211 is used for bonding and connecting with the lingual sides of the two adjacent front teeth 3, and part of the molding surface 211 is used for bearing the resin on the front teeth 3 to prevent the resin from flowing to the position protruding from the lingual side of the front teeth 3 under its own gravity ; The spacer 1 is used to be set in the gap between two adjacent front teeth 3, and part of the spacer 1 is used to contact the resin on the front teeth 3, so that the resin filled on the two front teeth 3 are spaced apart from each other, and a tooth gap is formed after the resin is solidified; the jaw plate group 2 and the spacer 1 cooperate with each other to have a plastic effect on the resin filled on the front teeth 3, and under the plasticity of the jaw plate group 2 and the spacer 1, the shape of the resin after solidification is adapted to the shape of the front teeth 3 itself, avoiding the formation of large protrusions of the resin on the lingual side of the front teeth, reducing the subsequent drilling and grinding of the solidified resin to adjust the shape, and improving the convenience of treating the front teeth 3 with proximal caries, so as to improve the treatment efficiency.

[0039] Reference Figure 1 and Figure 2 As shown, in some embodiments, the jaw plate group 2 includes two abutment plates 21, and the two abutment plates 21 are spaced apart along a first direction, one end of the spacer 1 is disposed between the two abutment plates 21 and connected to the two abutment plates 21; the other end extends along a second direction toward a direction away from the abutment plates 21; a shaping surface 211 is formed on the side of the abutment plate 21 toward the front teeth 3 along the second direction, and the shaping surfaces 211 of the two abutment plates 21 are respectively bonded and connected to the lingual sides of two adjacent front teeth 3 in a one-to-one manner; the first direction is perpendicular to the second direction. With such arrangement, since it is difficult for one plate structure to adapt to the shape of the two front teeth 3 when shaping the resin on the two front teeth 3 at the same time, the shaping effect of the resin on the two front teeth 3 by one plate is poor. The two abutment plates 21 are respectively bonded to the two front teeth 3 in a one-to-one correspondence, so that the two front teeth 3 can be shaped by the two abutment plates 21 respectively, and one abutment plate 21 can adapt to the shape of one front tooth 3, thereby improving the shaping effect of the jaw plate group 2 on the two front teeth 3 when filling with resin.

[0040] Specifically, Figure 1 and Figure 2 The directions indicated by the middle arrows are the first direction a and the second direction b. The first direction a can be selected as the arrangement direction of two adjacent front teeth 3, and the second direction b is the direction from the lingual side of the front teeth 3 to the labial side. The thickness direction of the abutment plate 21 is consistent with the second direction b.

[0041] The above-mentioned abutment plate 21 can be selected to extend along the first direction a so that the two abutment plates 21 are in the same plane, and an adhesive resin can be selected to be set on the side surface of the abutment plate 21 along the second direction b facing the front teeth 3, so that the side surface of the abutment plate 21 along the second direction b facing the front teeth 3 forms a shaping surface 211; of course, it is also possible to select a glue layer formed by medical glue to be set on the side surface of the abutment plate 21 along the second direction b facing the front teeth 3 to form a shaping surface 211 on the abutment plate 21.

[0042] The distance between the two abutment plates 21 along the first direction a can be chosen to be equal to the distance between the two front teeth 3 along the first direction a, so that the two abutment plates 21 can be bonded to the two front teeth 3 one by one respectively; of course, the spacer 1 can also be chosen to be deformable, so that after the spacer 1 is connected to the two abutment plates 21, the spacer 1 between the two abutment plates 21 is deformed and can change the distance between the two abutment plates 21, so that the two abutment plates 21 can adapt to two adjacent front teeth 3 with different spacings.

[0043] The above-mentioned spacer 1 can be selectively provided with two sheet structures at one end close to the abutment plate 21, and the two sheet structures are respectively provided on both sides of the spacer 1 along the first direction a, and the two sheet structures are respectively connected to the side edges of the two abutment plates 21 close to each other along the first direction a. Of course, it is also possible to select that the spacer 1 can be selected to be connected to the side edges of the two abutment plates 21 close to each other along the first direction a on both sides of the first direction.

[0044] The above-mentioned abutment plate 21 can be selected as an arc-shaped plate, and the abutment plate 21 is bent toward the front teeth 3 so that the shape of the abutment plate 21 adapts to the lingual side of the front teeth 3, thereby increasing the bonding strength between the shaping surface 211 and the lingual side of the front teeth 3.

[0045] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in some embodiments, the separator 1 includes a connecting piece 13, a separator 12 and two wing-shaped pieces 11, one end of the separator 12 is connected to the connecting piece 13, and the other end is connected to two wing-shaped pieces 11 arranged oppositely along the first direction, and the two wing-shaped pieces 11 are bent in the first direction away from each other; the connecting piece 13 is connected to two abutment plates 21, the separator 12 is used to be arranged in the gap between two adjacent front teeth 3, and the two wing-shaped pieces 11 are respectively arranged opposite to the labial sides of the two adjacent front teeth 3. In this way, the connecting piece 13 can connect the two abutment plates 21 with the separator 12, the separator 12 separates the resin on the two front teeth 3 to avoid contact between the resins on the two front teeth 3, and the two wing-shaped pieces 11 can have a shaping effect on the resin on the two front teeth 3, so that the resin can form an arc surface after curing, so that the shape of the resin on the front teeth 3 after curing is close to the shape of the front teeth 3 itself, reducing the subsequent operation of adjusting the shape of the cured resin, and improving the shaping effect of the separator 1 on the resin on the front teeth 3.

[0046] Specifically, the connecting piece 13 can be selected as a sheet structure extending along the first direction a, one end of the separating piece 12 is connected to the middle part of the connecting piece 13 along the first direction a, and the other end of the separating piece 12 is connected to the two wing-shaped pieces 11; the two wing-shaped pieces 11 are bent along the first direction in directions away from each other, and the two wing-shaped pieces 11 can be respectively opposite to the two front teeth 3; the side surfaces of the two adjacent front teeth 3 that are close to each other along the first direction are the adjacent surfaces of the front teeth 3, and the adjacent surfaces include a first area, a second area, and a third area, and the first area, the second area, and the third area are arranged in sequence along the second direction, and the first area is located on the side of the second area close to the labial side of the front teeth 3, and the third area is located on the side of the second area close to the lingual side of the front teeth 3, and the adjacent surfaces of the front teeth 3 have an arc, wherein the first area and the second area are arcuate surfaces, and the second area is a plane.

[0047] The connecting piece 13, the separating piece 12 and one wing-shaped piece 11 are used to shape the adjacent surface of one front tooth 3. The connecting piece 13, two wing-shaped pieces 11 and one separating piece 12 are capable of shaping the adjacent surfaces of two front teeth 3. The space 31 to be filled of the front teeth 3 forms a gap on the adjacent surfaces of the adjacent front teeth 3, and the gap covers the first area, the second area and the third area. After the resin is filled into the space 31 to be filled, the separating piece 12 is opposite to the second area, part of the connecting piece 13 is opposite to the third area, and the wing-shaped piece 11 is opposite to the first area. The two wing-shaped pieces 11 are bent in a direction away from each other to form an arc structure. The resin in the first area fits with the arc structure of the wing-shaped piece 11. After the resin solidifies, the resin in the first area can form an arc surface through the shaping of the wing-shaped piece 11, so that the shape of the resin after solidification is close to the shape of the front teeth 3 themselves.

[0048] When resin is filled on the adjacent surfaces of the two front teeth 3, the two wing-shaped pieces 11 can respectively shape the resin in the first area of ​​the two front teeth 3, so that after the resin of the two front teeth 3 is cured, an arc surface can be formed in the first area, and the shape of the resin after curing is similar to the shape of the front teeth 3 itself, so as to reduce the subsequent drilling and grinding operations on the cured resin.

[0049] Reference Figure 1 and Figure 2 As shown, in some embodiments, the abutment plate 21 includes a plurality of plate bodies, which are stacked and connected to each other along the second direction. In this way, the combination of the plurality of plate bodies improves the structural strength of the abutment plate 21, so that the abutment plate 21 is not easily deformed when bearing the resin, and the abutment plate 21 has a stable shaping effect on the resin, ensuring that the shape of the resin after contacting the abutment plate 21 and curing is similar to the tooth shape of the anterior teeth 3.

[0050] Specifically, the abutment plate 21 can be selected to include multiple layers of plastic plates, the multiple layers of plastic plates have the same shape and area, the multiple layers of plastic plates are stacked along the second direction b and connected to each other to form the abutment plate 21, and the multiple layers of plastic plates can be connected by bonding, or of course, by ultrasonic welding.

[0051] The above-mentioned abutment plate 21 is a composite plate structure, so that the structural strength of the abutment plate 21 is greater than that of the spacer 1, so that the abutment plate 21 is not easy to deform. After the resin in the space 31 to be filled contacts with the abutment plate 21, the abutment plate 21 can bear the gravity of the resin in the space 31 to be filled without large deformation, so that the abutment plate 21 has a stable shaping effect on the resin in the space 31 to be filled.

[0052] Reference Figure 1 and Figure 2 As shown, in some embodiments, the connecting sheet 13 includes two sub-sheets 131, the two sub-sheets 131 are arranged opposite to each other along the first direction, and the two sub-sheets 131 are connected to one end of the separator 12 close to the abutment plate 21 along the second direction; the two sub-sheets 131 are bent in the first direction in a direction away from each other, and the ends of the two sub-sheets 131 away from the separator 12 are respectively connected to the edges of the two abutment plates 21 close to each other. With such an arrangement, the two sub-sheets 131 can shape the resin on the two front teeth 3, so that the resin can form an arc surface after curing, so that the shape of the resin on the front teeth 3 after curing is close to the shape of the front teeth 3 itself, reducing the subsequent operation of adjusting the shape of the cured resin, and improving the shaping effect of the separator 1 on the resin on the front teeth 3.

[0053] Specifically, the two sub-pieces 131 are bent in directions away from each other, so that the side of the sub-piece 131 facing the front teeth 3 forms an arcuate surface, and the sub-piece 131 is arranged opposite to the third area of ​​the front teeth 3. The resin in the space 31 to be filled contacts part of the sub-piece 131 at the gap formed in the third area of ​​the front teeth 3, so that the sub-piece 131 shapes the resin. After the resin is cured, the part located in the third area forms an arcuate surface along the arc structure of the sub-piece 131, so that the shape of the resin after curing is similar to the shape of the front teeth 3 itself, so as to reduce the subsequent drilling and grinding operations on the cured resin.

[0054] The above-mentioned two sub-sheets 131 can be selected to be connected to each other, and the separator 12 is connected to the connection between the two sub-sheets 131, so that the two sub-sheets 131 are connected to one end of the separator 12 close to the abutment plate 21. Of course, the two sub-sheets 131 can also be selected to be connected to one end of the separator 12 close to the abutment plate 21 respectively. As long as the two sub-sheets 131 are bent toward the abutment plates 21 on both sides of the separator 12 along the first direction, the two sub-sheets 131 can be connected to the two abutment plates 21 respectively, so that the sub-sheets 131 have a shaping effect on the resin on the adjacent surfaces of the anterior teeth 3.

[0055] Reference Figure 1 and Figure 2 As shown, in some embodiments, at least the connecting piece 13 is elastic. In this way, the elastic deformation of the connecting piece 13 can change the distance between the two abutment plates 21, so that the two abutment plates 21 are adapted to the two front teeth 3 with different sizes of tooth gaps, thereby improving the application range of the molding sheet for interproximal caries.

[0056] Specifically, the connecting piece 13 can be made of elastic plastic, and of course, the connecting piece 13 and the separating piece 12 can also be made elastic, or the wing-shaped piece 11, the separating piece 12 and the connecting piece 13 are not limited to being elastic. The elastic deformation of the connecting piece 13 can change the distance between the two abutting plates 21, so that the two abutting plates 21 are adapted to the two front teeth 3 with different sizes of tooth gaps, thereby improving the application range of the molding sheet for interproximal caries.

[0057] Reference Figure 1 and Figure 2 As shown, in some embodiments, the shaping surface 211 is an arcuate surface convex toward the spacer 1. Such a configuration enables the arcuate shaping surface 211 to cooperate with the shape of one side of the lingual side of the anterior teeth 3, increases the area where the shaping surface 211 fits the anterior teeth 3, improves the stability of the bonding between the shaping surface 211 and one side of the lingual side of the anterior teeth 3, and the resin forms an arcuate structure on the arcuate shaping surface 211, so that the shape of the surface of the resin solidified on the lingual side of the anterior teeth 3 is adapted to the shape of the surface of the lingual side of the anterior teeth 3 themselves.

[0058] Specifically, the shaping surface 211 is an arcuate surface, and one side of the lingual side of the front teeth 3 is an arcuate surface that is concave toward the labial side of the front teeth 3 , so that the shape of the arcuate shaping surface 211 matches one side of the lingual side of the front teeth 3 .

[0059] Reference Figures 1 to 4 As shown, in some embodiments, a bonding resin is provided on the shaping surface 211, and the shaping surface 211 is bonded and connected to the lingual side of the front teeth 3 through the bonding resin. In this way, the bonding resin is non-toxic and suitable for oral treatment, and the bonding force of the bonding resin is moderate, so that the bonding resin can bond the abutment plate 21 to the front teeth 3, and the abutment plate 21 can be removed from the front teeth 3 without using excessive force, thereby avoiding damage to the tooth body of the front teeth 3 when the abutment plate 21 is removed from the front teeth 3.

[0060] Specifically, a bonding resin can be provided on a partial area of ​​the shaping surface 211 away from the spacer 1, so that after the shaping surface 211 is attached to the lingual side of the front teeth 3, the portion of the shaping surface 211 close to the spacer 1 shapes the resin on the front teeth 3, and the portion of the shaping surface 211 away from the spacer 1 is used to bond with the lingual side of the front teeth 3 through the bonding resin.

[0061] Reference Figure 1 to Figure 2 As shown, in some embodiments, at least the spacer 1 is light-transmissive. This arrangement facilitates the resin curing lamp to illuminate the resin on the front teeth 3 through the spacer 1, so that the resin is fully cured, thereby improving the convenience of the resin curing operation.

[0062] Specifically, the spacer 1 can be made of transparent plastic so that the wing-shaped piece 11, the dividing piece 12 and the connecting piece 13 are all light-transmissive. Of course, the spacer 1 and the two abutment plates 21 can also be light-transmissive. Since most of the resins used in dental treatment are light-curing resins, at least the spacer 1 is light-transmissive, so that the doctor can use a curing lamp to irradiate the resin on the front teeth 3 through the spacer 1, thereby facilitating the curing operation of the resin.

[0063] When the molding sheet for proximal surface caries provided by the embodiment of the present disclosure is specifically used, the carious area of ​​the front teeth 3 is removed to form a space 31 to be filled, and an adhesive resin is set on the shaping surface 211 of the abutment plate 21, and the abutment plate 21 is bonded to one side of the lingual side of the front teeth 3, and two abutment plates 21 are bonded to one side of the lingual side of the two front teeth 3, and the spacer 1 is set in the gap between the two front teeth 3. The space 31 to be filled is filled with resin, and the resin contacts the part of the shaping surface 211 close to the spacer 1, and the resin of one front tooth 3 contacts the spacer 12, a partial area of ​​a sub-sheet body 131 and a partial area of ​​an airfoil 11, so that the spacer 12, the sub-sheet body 131 and the airfoil 11 jointly shape the resin on the front teeth 3, and a curing lamp is used to irradiate the resin through the spacer 1 to cure the resin in the space 31 to complete the filling operation of the proximal surface carious part of the front teeth 3. After the resin is cured, the abutment plate 21 is separated from the lingual side of the front teeth 3, the spacer 1 is pulled out from the gap between the two front teeth 3, and the edges and corners formed after the resin is cured are ground off using a dental drill to avoid scratching the tongue.
