[0002] Invisible braces are an important part of modern orthodontic technology. In the process of invisible braces, accessories of the same color as the teeth and transparent braces are required. Specifically, transparent accessories are bonded to the tooth surface, and then transparent braces are installed on the bonded accessories for correction. The accessories play a role in retention and force application. The firmness and stability of the attachment bonding affect the patient's correction process and correction effect. If the attachment falls off, it may cause the invisible braces to come off, prolong the correction process, and other unfavorable situations.

[0003] The material used to make up the attachment is a light-curing resin, which needs to be used in conjunction with a template. The template is provided with an attachment molding cavity, and the light-curing resin is filled into the attachment molding cavity and light-cured to form an attachment. In clinical practice, in order to ensure the firmness and stability of the attachment bonding and the convenience of removing excess resin around the attachment, four-hand operation is required: while one person operates the light-curing device to light-cure the light-curing resin, another person is required to pressurize the attachment molding cavity and the surrounding template, and the pressing process cannot block the light of the light curing. It is usually difficult to operate due to factors such as poor vision and narrow oral cavity, and multi-hand operation brings a lot of discomfort to patients. Utility Model Content

[0026] Example 1

[0027] A conversion head of an invisible correction accessory light curing lamp, comprising: a main body part and a connecting part;

[0028] like Figure 1 As shown, the main body portion includes a connecting end 1 and a pressing end 2 opposite to each other, the connecting end 1 is connected to the light curing lamp through a connecting portion 3, and the pressing end 2 is used to apply pressure to the attachment;

[0029] The main body is provided with a middle hollow channel 4 which passes through the surface of the connecting end 1 and the surface of the pressing end 2, and the middle hollow channel 4 is used to allow the curing light of the light curing lamp to irradiate the light curing resin in the accessory molding cavity 9;

[0030] The cross-sectional shape of the middle hollow channel 4 is the same as the shape of the accessory forming cavity 9;

[0031] The material of the main body is an elastic porous material; preferably, the material of the main body is a TPE-based elastic porous material; because the material is soft and elastic, it can achieve a better pressing effect on accessories of the same shape and slightly larger size.

[0032] The material of the main part is absorbent and can absorb saliva in the patient's mouth, effectively isolating moisture.

[0033] Since the middle hollow channel 4 has the same shape as the accessory molding cavity 9, during light curing, the main body can be pressed and rubbed against the side wall of the accessory molding cavity 9 to apply downward pressure and press the template 8 as a whole. The operation is simple and can be completed by one doctor, which also reduces the discomfort caused to the patient.

[0034] The connecting part 3 is a sheet of double-sided adhesive, which is used to bond the main body to the light curing lamp.

[0035] The shape of the sheet-like double-sided adhesive is the same as the shape of the surface of the connecting end 1, so that the connecting end 1 can be effectively bonded to the light curing lamp.

[0036] The sheet-like double-sided adhesive adhered to the surface of the connection end 1 is covered with a smooth film 5, which can be torn off and can maintain stickiness for a long time before use. When in use, the smooth film 5 is torn off and the main part is bonded to the light curing lamp.

[0037] The middle hollow channel 4 is arranged at the geometric center of the surface of the pressing end 2 of the main body part, so that force can be evenly applied around the middle hollow channel 4 when pressing.

[0038] In order to ensure that the pressing end 2 presses the accessory molding cavity 9 and the surrounding template 8 evenly, the end surface of the pressing end 2 has the same shape as the template 8 around the pressed accessory molding cavity 9.

[0039] In order to ensure that the main body has a certain strength, the side wall thickness of the main body is greater than 1 mm.

[0040] Preferably, the cylindrical main body can be in different colors, such as black, blue, etc., to symbolize accessories of different shapes for easy distinction.

[0041] The method for preparing the conversion head of the invisible correction accessory light curing lamp in this embodiment is as follows: Figure 2 As shown, the following steps are included:

[0042] S1. Using industrial 3D design software to design and build a 3D model of the main part according to the size and shape of the attachment, the cross-sectional shape of the middle hollow channel 4 is the same as the shape of the attachment, and the cross-sectional shape is not larger than the size of the attachment;

[0043] S2. Using 3D printing equipment, selecting elastic porous materials, and preparing a conversion head of an invisible correction accessory light curing lamp according to the three-dimensional model;

[0044] S3. Install the connecting part 3 on the connecting end 1 of the adapter to obtain a conversion head for the invisible correction accessory light curing lamp.

[0045] The printing material is TPE material, that is, thermoplastic rubber, which is a widely used 3D printing raw material.

[0046] Since there are many shapes of accessories, including rectangle, crescent, etc., and multiple models are included, the corresponding accessory molding cavity 9 also has various shapes. Different accessories require corresponding intermediate hollow channels 4 of different shapes. The main body of the conversion head of the invisible orthodontic accessory light curing lamp is prepared by a 3D printing method. It can be flexibly adjusted according to the shape of the accessory and the condition of the tooth surface, and the manufacturing method is simple and fast.

[0047] In S2, the elastic porous material is a foamed porous TPE-type material, which forms a porous structure through a foaming process and effectively absorbs liquid.

[0048] In S3, the sheet-like double-sided adhesive is cut into the same shape as the surface of the connection end 1 of the main body part, and is pasted on the surface of the connection end 1 of the main body part.

[0049] The method for using the conversion head of the invisible correction accessory light curing lamp comprises the following steps:

[0050] Step 1: Figure 3 As shown, the accessory molding cavity 9 of the template 8 is filled with light-curing resin, and then the template 8 with the accessory molding cavity 9 filled with light-curing resin is buckled onto the tooth surface 7 of the patient;

[0051] Step 2: Place the connection end 1 of the conversion head of the invisible correction accessory light curing lamp on the light curing lamp 6, so that the curing light passes through the middle hollow channel 4 and is emitted from the opening of the middle hollow channel 4 of the pressing end 2;

[0052] Step 3: Press the pressing end 2 of the conversion head of the invisible orthodontic accessory light curing lamp on the template 8 around the accessory molding cavity 9, and make the accessory molding cavity 9 located in the middle hollow channel 4, and press toward the tooth surface 7 during the light curing process until the light curing is completed, to obtain the accessory 11 cured by the light curing resin;

[0053] Step 4: Remove the template 8 and grind the excess resin material 10 around the attachment 11 except for the attachment to obtain Figure 4 The attachment 11 is shown firmly bonded to the tooth surface 7.

[0054] In step three, since the template 8 is made of transparent material, the curing light can pass through the template 8 and irradiate onto the light-curable resin to achieve the curing of the resin.

[0055] Among them, the template 8 includes an accessory molding cavity 9, and the template 8 around the accessory molding cavity 9 can fit with the tooth surface 7. The method of preparing the accessory 11 bonded to the tooth surface 7 by using the template 8 with the accessory molding cavity 9 is the prior art, and the present technical solution does not improve on this.

[0056] Since the main body has a certain elasticity and the cross-section of the middle hollow channel 4 is the same as the shape of the accessory molding cavity 9, the main body of the conversion head can effectively press the photocurable resin in the accessory molding cavity 9 through the friction force of the side of the accessory molding cavity 9; it can maximally standardize the forming shape of the photocurable resin in the accessory molding cavity 9, squeeze the excess resin material 10 out of the accessory molding cavity 9, overflow and form a thin sheet of excess resin material 10 between the surrounding template 8 and the tooth surface 7. Since the photocurable resin itself can guide light, the photocurable resin that is compressed thinly under the main body will also be cured into a thin sheet. The thin sheet of excess resin material 10 is easier to grind, which greatly saves the doctor's operation time.

[0057] On the other hand, the photocuring process takes a long time. The porous main body can absorb the saliva in the patient's mouth, effectively isolating it from moisture, eliminating the need for doctors to suck saliva, and further simplifying the doctor's operating steps.

[0058] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
