Technical Field

[0001] The present application relates to the field of orthodontic technology, and in particular to a bracket bonding method. Background Art

[0002] Orthodontic brackets are a traditional medical device used to correct deformed teeth. During orthodontic treatment, the brackets and teeth are required to have a good bonding effect in order to provide convenience and reliable bonding strength for subsequent treatment.

[0003] The curvature of the existing bracket mesh bottom and the curvature of the tooth surface cannot be perfectly matched, resulting in many brackets being in an abnormal position after bonding. The straight wire theory requires that the tooth wire should be a smooth arc (without twists) in the final position of correction, which requires the bracket and the tooth surface curvature to be perfectly matched as a basis. Therefore, in the existing correction methods, the position of the orthodontic bracket when bonded to the teeth is not reasonable enough, resulting in the tooth wire still not being able to present a smooth arc when the correction is completed, and failing to meet the requirements of the straight wire theory. Summary of the invention

[0004] The purpose of the present application includes providing a bracket bonding method, which has a better bonding effect, so that the position of the orthodontic bracket on the tooth is more reasonable and more in line with the requirements of the straight wire arch theory.

[0014] According to the final target position of each orthodontic bracket and the target tooth shape, the thickness of the bonding gap between the mesh bottom of each orthodontic bracket and the tooth is determined.

[0015] In an optional implementation, the thickness of the bonding gap is controlled to be between 0.01 mm and 1 mm.

[0034] Figure 1 This is a flow chart of a bracket bonding method in one embodiment of the present application. Figure 1 As shown, the bracket bonding method provided by the present application is used to bond orthodontic brackets on teeth, and the bracket bonding method includes:

[0035] Step S100, determining the thickness of the bonding gap between the mesh bottom of each orthodontic bracket and the tooth, the thickness of the bonding gap satisfies: when the tooth is corrected to the target tooth shape, the tooth wire passing through each orthodontic bracket meets the straight wire arch requirement.

[0036] It can be understood that after the teeth are corrected to the target tooth shape, the teeth are arranged relatively neatly, but due to the uncertainty of each person's tooth surface and tooth shape, even the orthodontic brackets attached to the neatly arranged teeth may not necessarily meet the straight wire arch theory, that is, the tooth wire passing through these orthodontic brackets may not present a smooth arc shape, which will affect the correction effect. Therefore, in order to make the tooth wire smooth when the correction is completed, it is necessary to determine the position of each orthodontic bracket at the end of the correction. Usually, their positions should be neatly arranged. However, the position of the neatly arranged orthodontic brackets that can meet the requirements of the straight wire arch does not necessarily fit perfectly with the final desired tooth shape. There may be different gaps between the mesh bottom of the orthodontic bracket and the teeth. This part of the gap is to be filled with glue, that is, the bonding gap. In the embodiment of the present application, the thickness of the bonding gap between the mesh bottom of the orthodontic bracket and the tooth must first be determined. Determining the thickness of the bonding gap is the basis for ensuring that the tooth wire is a smooth arc shape (i.e., meeting the requirements of the straight wire arch) after the final correction is completed. Figure 2This is a flow chart of determining the thickness of the bonding gap between the mesh bottom of each orthodontic bracket and the tooth in one embodiment of the present application. In this embodiment, the step of determining the thickness of the bonding gap between the mesh bottom of each orthodontic bracket and the tooth may include:

[0037] Step S110, obtaining a target tooth shape according to the current tooth shape.

[0038] It is understandable that the tooth shape of each patient is different. There are differences in the current tooth shape before correction and the target tooth shape after correction. Through simulation, the target tooth shape can be obtained using the patient's current tooth shape. The current tooth shape is the tooth shape before correction, and the target tooth shape is the tooth shape expected to be achieved after correction (often neat). In a specific embodiment, the patient's tooth model (corresponding to the current tooth shape) can be obtained and imported into the software for final tooth arrangement to obtain the target tooth shape.

[0039] Step S120, determining the final target position of each orthodontic bracket according to the target tooth shape, when each orthodontic bracket is at the final target position, the tooth wire passing through each orthodontic bracket meets the straight wire arch requirement.

[0040] Step S130, determining the thickness of the bonding gap between the mesh base of each orthodontic bracket and the tooth according to the final target position of each orthodontic bracket and the target tooth shape.

[0041] In an optional embodiment, the orthodontic bracket can be arranged by software so that it is in the final target position, and the orthodontic bracket in the final target position meets the straight wire arch requirements. After the position is determined, the distance between the mesh bottom of the orthodontic bracket and the tooth surface (i.e., the thickness of the bonding gap) is calculated, the highest point of the tooth surface is screened out in the software, and the highest point between the mesh bottom of the bracket and the tooth surface is measured to ensure that the maximum distance does not exceed the preset range. It can be understood that for the patient's final target tooth shape, there may be more than one final target position of the orthodontic bracket that can meet the straight wire arch requirements. Therefore, after the bonding gap exceeds the preset range, the final target position of the orthodontic bracket can be adjusted so that the bonding gap meets the requirements. In this embodiment, the thickness of the bonding gap is the distance between the mesh bottom of the orthodontic bracket and the highest point of the tooth surface opposite the mesh bottom, and the thickness can be controlled at 0.01mm to 1mm. It should be understood that the thickness of the bonding gap should be set according to actual needs. For example, in some cases, if the highest point of the tooth surface is too high, the thickness of the gap should be appropriately reduced to avoid the bracket being too convex and causing a decrease in comfort.

[0042] It is understandable that the highest point of the tooth surface is often the position with relatively weak bonding force, because in the traditional bonding method, the adhesive between the highest point of the tooth surface and the mesh bottom of the orthodontic bracket is the least, and even after the orthodontic bracket is squeezed, the highest point of the tooth surface directly contacts the mesh bottom, resulting in weak bonding strength in this area. In this embodiment, the highest point position information of the tooth surface is obtained, and a gap of a preset thickness is reserved between the highest point and the mesh bottom, which can ensure that even the highest point of the tooth can be bonded to the mesh bottom with sufficient adhesive.

[0043] Step S200, determining the initial target position of the orthodontic bracket according to the thickness of the bonding gap and the current tooth shape.

[0044] In this embodiment, after the thickness of the bonding gap is calculated, the initial target position of each orthodontic bracket can be determined using the thickness of the bonding gap and the patient's current tooth shape. Similarly, the initial target position of the orthodontic bracket can be obtained through software. It should be understood that the initial target position of the orthodontic bracket is relative to the position of the teeth before correction. When the orthodontic bracket is in the initial target position, the distance between the orthodontic bracket and the teeth before correction is exactly the thickness of the bonding gap.

[0045] Step S300, obtaining an orthodontic locator according to the initial target position of the orthodontic bracket.

[0046] When the initial target position of the orthodontic bracket is determined, an orthodontic positioner can be made according to the initial target position. The orthodontic positioner is used to be installed in the patient's mouth to fix the orthodontic bracket at the initial target position relative to the teeth and enable the orthodontic bracket to be accurately bonded to the teeth.

[0047] Step S400: fix the position of the orthodontic bracket relative to the tooth using an orthodontic positioner, and fill the bonding gap with an adhesive.

[0048] In this embodiment, after the orthodontic bracket is fixed by using the orthodontic positioner, there is a reserved gap between the mesh bottom of the orthodontic bracket and the corresponding tooth, and the gap can be used to accommodate sufficient adhesive to make the bonding between the orthodontic bracket and the tooth stronger, and the gap is calculated, which adjusts the position of the orthodontic bracket relative to the tooth, so that the position of the orthodontic bracket after the final correction is completed can meet the requirements of the straight wire arch.

[0049] In an optional embodiment, before the step of fixing the orthodontic bracket at a target position relative to the tooth using an orthodontic positioner, the bracket bonding method includes:

[0050] A pretreatment agent is added to the adhesive for blending to increase the fluidity of the adhesive, and the blended adhesive is applied to the mesh bottom of the orthodontic bracket.

[0051] In conventional light-curing bonding, it is necessary to first apply a pre-treatment agent to the mesh bottom and the tooth surface, and then apply an adhesive to the mesh bottom for bonding. As an improvement, in this embodiment, it is necessary to first mix the pre-treatment agent with the adhesive, and then apply it to the mesh bottom. This increases the fluidity of the adhesive, so that the adhesive can more effectively bond the mesh bottom and the tooth surface.

[0052] In summary, the bracket bonding method provided in the embodiment of the present application includes determining the thickness of the bonding gap between the mesh bottom of each orthodontic bracket and the tooth, and the thickness of the bonding gap satisfies that when the tooth is corrected to the target tooth shape, the tooth wire passing through each orthodontic bracket meets the straight wire arch requirement. Then, according to the thickness of the bonding gap and the current tooth shape, the initial target position of the orthodontic bracket is determined. Then, the orthodontic positioner is obtained according to the initial target position of the orthodontic bracket, and the position of the orthodontic bracket relative to the tooth is fixed by the orthodontic positioner, and the bonding gap is filled with an adhesive. In the embodiment of the present application, since the thickness of the bonding gap between the mesh bottom of the orthodontic bracket and the tooth has been determined when the orthodontic bracket is bonded, and the thickness can meet the straight wire arch requirement, after the orthodontic positioner is used to position the orthodontic bracket, the bonding gap between the orthodontic bracket and the tooth is the most reasonable, and the tooth wire can be in a smooth arc after the correction is completed, thereby meeting the straight wire arch requirement. Therefore, the bracket bonding method can ensure a good bonding effect.

[0053] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
