Description

Technical Field

[0001] The present application relates to the technical field of dental treatment appliances, and in particular to a prefabricated crown that is anti-slip and anti-falling. Background Art

[0002] Prefabricated crowns are a type of dental material used to repair diseased teeth. They are usually made of metal alloys or all-ceramics, such as titanium alloys, palladium alloys or cobalt-chromium alloys, all-ceramics, etc. Prefabricated crowns can cover the surface of diseased teeth, restore their function and appearance, and protect them from further damage. They can provide additional support and stability to the teeth, preventing the diseased teeth from breaking or shifting. They help restore the normal chewing function of the diseased teeth, allowing patients to eat normally.

[0003] Before installing a crown for a patient, the doctor first needs to grind the affected tooth to leave enough space for the crown. Ensure the fit and comfort of the crown with the surrounding teeth. Then, the doctor will obtain a model of the affected tooth to make a customized crown or directly select a suitable finished pre-made crown. Finally, the crown is bonded to the ground tooth with adhesive. Before bonding the crown to the tooth with adhesive, the doctor needs to repeatedly adjust the position between the tooth and the crown to ensure a better fit between the crown and the surrounding teeth. This requires the doctor to hold the crown repeatedly and for a long time. However, because the outer wall of the crown is relatively smooth. Especially for young children, the crown of deciduous teeth is relatively small and easy to slip off during the holding process, and the fallen crown is easy to be swallowed by mistake.

[0004] Therefore, the above-mentioned technical defects need to be changed urgently. Utility Model Content

[0005] In view of the above-mentioned deficiencies in the prior art, the purpose of the present application is to provide a prefabricated crown that is anti-slip and anti-falling, aiming to increase the friction between the crown and the surface, and effectively prevent the crown from slipping when the doctor holds the crown.

[0028] In addition, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.

[0029] On the one hand, the utility model provides Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a prefabricated crown that is anti-slip and anti-falling can be used to repair diseased teeth. When in use, the crown is covered on the surface of the diseased tooth to restore its function and appearance, protect the tooth from further damage, provide additional support and stability for the tooth, and prevent the diseased tooth 3 from breaking or shifting. It helps to restore the normal chewing function of the diseased tooth 3 so that the patient can eat normally. The main structure includes: a crown body 1 and an anti-slip patch 2. The crown body 1 includes a crown periphery 11 and a crown top 12. The crown top 12 is arranged on the top of the crown periphery 11. The crown top 12 and the crown periphery 12 enclose a crown cavity 13 with an opening at the lower end. The crown cavity 13 is used to accommodate the diseased tooth 3. The crown body 1 is sleeved on the diseased tooth 3 through the crown cavity 13. When in use, it is usually necessary to apply adhesive in the crown cavity 13 to enhance the connection strength between the crown body 1 and the diseased tooth 3; wherein the crown periphery 11 includes a tongue wall portion 111 facing the tongue side of the oral cavity and a buccal wall portion 112 facing the buccal side of the oral cavity, and the tongue wall portion 111 and the buccal wall portion 112 are arranged opposite to each other;

[0030] The anti-slip patch 2 includes an adhesive surface 21 and an anti-slip surface 22. The anti-slip patch 2 is adhered to the outer wall of the crown body 1 through the adhesive surface 21. The adhesive surface 21 and the anti-slip surface 22 are arranged opposite to each other, and the anti-slip patch 2 is detachably connected to the crown body 1. After the crown body 1 is fixed on the patient's tooth 3, the anti-slip patch 2 adhered to the crown body 1 can be torn off. The crown periphery 11 of the crown body 1 remains smooth. It is understandable that the adhesive used on the adhesive surface 21 of the anti-slip patch 2 is environmentally friendly and harmless to the human body. For example, water-based adhesives: water-based adhesives are more environmentally friendly than traditional organic solvent-based adhesives, and are generally harmless to the human body. This type of adhesive is mainly composed of water and a small amount of organic matter, and does not release harmful gases when used.

[0031] It should be noted that before bonding the crown body 1 to the affected tooth with an adhesive, the doctor needs to repeatedly adjust the position between the affected tooth and the crown body 1 to ensure that the crown body 1 fits better with the surrounding teeth. This requires the doctor to hold the crown body 1 repeatedly and for a long time. However, since the outer wall of the crown body 1 is relatively smooth, especially the deciduous tooth crown for children is relatively small, the crown is easy to slip off during the holding process, and the fallen crown is easy to be swallowed by mistake.

[0032] During use of the present application, the doctor can hold the crown by holding the anti-slip patch 2. The anti-slip patch 2 is made of a soft material, and the friction of the anti-slip surface 22 is relatively large. The anti-slip patch 2 is bonded to the crown body 1. Therefore, when the doctor is holding the crown body 1, the crown body 1 will not slip off, thus avoiding the risk of accidental swallowing caused by the crown body 1 slipping off during the hand-holding process, and effectively improving the efficiency of the doctor's operation. In addition, after the crown body 1 is installed, the medical staff can separate the anti-slip patch 2 from the crown body 1 to keep the surface of the crown periphery 11 of the crown body 1 smooth. Reduce the foreign body sensation in the patient's mouth.

[0033] Further, such as Figure 1 , Figure 2 As shown, the anti-slip surface 22 is arranged on the anti-slip patch 2 near the crown periphery 11, so as to facilitate the doctor to hold the crown body 1.

[0034] Further, such as Figure 1 , Figure 2 As shown, the anti-slip patch 2 is simultaneously attached to the tongue wall 111, the crown top 12 and the cheek wall 112 through the adhesive surface 21. It is understandable that when the doctor holds the crown body 1, he usually holds the tongue wall 111 and the cheek wall 112. The gap between the other two sides of the crown body 1 and the adjacent teeth is too small to be held. Therefore, in this embodiment, the anti-slip surface 22 is set on the anti-slip patch 2 near the crown periphery 11 to facilitate the doctor to hold the crown body 1.

[0035] Further, such as Figure 1 , Figure 2 and Figure 3As shown, the thickness of the anti-slip patch 2 near the tongue wall 111 and the cheek wall 112 is greater than the thickness of the part near the crown top 12. Because the clamping tool is clamped on the anti-slip patch 2 near the tongue wall 111 and the cheek wall 112 when the doctor clamps the crown body 1, the anti-slip patch 2 near the tongue wall 111 and the cheek wall 112 is subjected to the clamping pressure. In order to ensure sufficient friction, the anti-slip patch 2 near the tongue wall 111 and the cheek wall 112 needs to be configured to be thicker. Secondly, the part of the anti-slip patch 2 near the crown top 12 is a friction surface for connecting the two ends. In order to facilitate the bending and straightening of the anti-slip patch 2, the part of the anti-slip patch 2 near the crown top 12 needs to be configured to be thinner.

[0036] Further, such as Figure 1 , Figure 2 and Figure 3 As shown, the anti-skid surface 22 is provided with a first anti-skid pattern 221. The first anti-skid pattern 221 is used to increase the friction of the anti-skid surface 22 and prevent the first anti-skid pattern 221 from slipping with the clamping tool.

[0037] Further, such as Figure 1 , Figure 2 and Figure 3 As shown, at least one gripping portion 23 is provided on the edge of the anti-slip patch 2 near the tongue wall portion 111 and the cheek wall portion 112, and a gap is maintained between the gripping portion 23 and the crown body 1. As the name implies, the gripping portion 23 can help the doctor tear the anti-slip patch 2 off the crown body 1 more conveniently. A gap is maintained between the gripping portion 23 and the crown body 1, so that one side of the clamping tool can extend into the gap between the gripping portion 23 and the crown body 1, and then the gripping portion 23 is clamped to tear off the anti-slip patch 2.

[0038] Further, such as Figure 1 , Figure 2 and Figure 3 As shown, the anti-slip patch 2 is provided with a through connection hole. The medical staff can bolt a safety rope on the connection hole and pull the crown body 1 through the safety rope. When the crown body 1 accidentally falls off, the medical staff can take the crown out of the patient's mouth through the safety rope to prevent the crown body 1 from being swallowed by the patient.

[0039] Furthermore, the anti-slip patch 2 is configured as a silicone material structure. The silicone material has good elasticity and a high friction coefficient, and is suitable for use as an anti-slip material.

[0040] Furthermore, the crown body 1 is configured as an integrally formed alloy structure.

[0041] Further, such as Figure 4As shown, a second anti-slip pattern 14 is provided on the side wall of the crown cavity 13. The second anti-slip pattern 14 in the side wall of the crown cavity 13 can increase the adhesion of the adhesive, making the bonding between the crown body 1 and the diseased tooth 3 more secure.

[0042] Furthermore, arc-shaped recessed portions 25 are provided at two positions on the anti-slip surface 22 corresponding to the tongue wall portion 111 and the cheek wall portion 112, and the two arc-shaped recessed portions 25 are arranged opposite to each other. It can be understood that when the medical staff holds the crown body 1, they can pinch the position of the arc-shaped recessed portion 25 with their fingers. The curvature of the outer skin of the finger matches the inner curvature of the arc-shaped recessed portion 25. Therefore, the arc-shaped recessed portion 25 can help the medical staff better hold the crown body 1 and prevent the crown body 1 from slipping.

[0043] In summary, the present application provides a prefabricated crown that is non-slip and non-detachable. During use, the doctor can hold the non-slip patch 2 to clamp the crown body 1. Since the non-slip patch 2 is bonded to the crown body 1, the crown body 1 will not slip when the doctor is clamping the crown body 1. In addition, after the crown is installed, the medical staff can separate the non-slip patch 2 from the crown body 1 to keep the periodontal surface of the crown smooth.

[0044] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
