Description

Manufacturing method of accessory installation template assembly
Technical Field
The present application relates generally to a method of making an accessory mounting template assembly.
Background
Shell-like dental appliances made of polymeric materials are becoming more popular because of their aesthetic appearance, convenience, and cleaning benefits. In general, orthodontic treatment using shell appliances requires a series of successive shell appliances, each of which has a tooth-receiving cavity geometry that substantially matches the desired tooth arrangement for the corresponding appliance step.
In many cases, it is difficult to ensure that a correct force system with appropriate magnitude and direction is applied to the teeth by simply relying on the shell-shaped dental appliance itself. For example, when moving a tooth in the mesial or distal direction of the dental arch, although the desired movement is translation of the tooth, in practice, a large tilting moment is easily generated, so that the incisal end of the tooth is excessively moved to the same side as the movement direction, thereby causing an undesirable tilting movement of the tooth. In clinical practice, in order to avoid the above problems, in order to apply the correction force system on the teeth, which is closer to the design target, it is often necessary to additionally fix a convex attachment with a certain shape on the teeth by means of adhesion or the like, form a corresponding cavity for accommodating the attachment on the shell-shaped dental appliance, and apply an auxiliary force system to the teeth by the squeezing and friction action between the cavity and the attachment, so that the total correction force system applied to the teeth is closer to the desired force system. It follows that the attachment is critical to orthodontic treatment using a shell dental appliance.
Since the size of the attachment is typically small (e.g., 2-3mm), it is a challenge to accurately and securely fix the attachment in a predetermined orientation on the tooth surface. Accordingly, there is a need to provide a solution for precisely securing attachments to tooth surfaces in selected orientations.

The following detailed description refers to the accompanying drawings, which form a part of this specification. The exemplary embodiments set forth in the specification and drawings are for illustrative purposes only and are not intended to limit the scope of the present application. Those of skill in the art should, in light of the present disclosure, appreciate that many other embodiments can be utilized and that changes can be made in the embodiments described without departing from the spirit and scope of the present application. It will be readily understood that the aspects of the present application, as generally described and illustrated herein, could be arranged, substituted, combined, separated, and designed in a wide variety of different configurations, all of which are within the scope of the present application.
An aspect of the present application provides an accessory mounting template assembly and a method of making the same, wherein a 3D printing technique is used to make an integrated accessory mounting template assembly, which includes an accessory mounting template and an accessory, wherein the accessory mounting template holds and positions the accessory, which is detachable, and wherein the accessory is located in a predetermined orientation on the surface of a patient's tooth when the accessory mounting template assembly is worn on the patient's tooth. And after the adhesive applied to the bottom surface of the accessory is cured, mutually separating the accessory and the accessory mounting template, and removing the accessory mounting template from the patient tooth to complete the mounting of the accessory on the patient tooth.
Referring to FIG. 1, a schematic flow chart of a method 100 for making an accessory mounting template assembly in one embodiment of the present application is shown.
In 101, a three-dimensional digital model of a patient's teeth is acquired.
The shell-shaped dental appliance is used for dental orthodontic treatment, a series of successive shell-shaped dental appliances are needed, and the shell-shaped dental appliances are sequentially worn in order to sequentially reposition the dentition of a patient from the original layout to the first middle layout and the second middle layout. Each shell-shaped dental appliance corresponds to a correction step for repositioning the patient's dentition from the initial placement of the correction step to the target placement of the correction step.
In one embodiment, the three-dimensional digital model of the patient's teeth used to make the accessory mounting template assembly may be a three-dimensional digital model representing the layout of the patient's teeth when an accessory is mounted.
In one embodiment, the three-dimensional digital model of the patient's teeth may be a three-dimensional digital model of the entire dentition, for example, the entire maxillary or mandibular dentition. In yet another embodiment, the three-dimensional digital model of the patient's teeth may be a three-dimensional digital model of a portion of the dentition, for example, a segment of the dentition including teeth to which attachments are to be attached.
Methods for obtaining a three-dimensional digital model of a patient's teeth are well known in the art, and for example, a three-dimensional digital model representing a current tooth layout of a patient may be obtained by intraoral scanning, and will not be described in detail herein.
Referring to FIG. 2, a three-dimensional digital model 200 of a patient's teeth is schematically illustrated in one embodiment of the present application.
At 103, a three-dimensional digital model of an accessory mounting template assembly is generated based on the three-dimensional digital model of the patient's teeth.
In one embodiment, the following method may be used to generate a three-dimensional digital model of an attachment mounting template assembly based on the three-dimensional digital model 200 of the patient's teeth.
First, a first shell-like three-dimensional digital model 300a-1 as shown in FIG. 3A is obtained based on the outer surface of the portion of the three-dimensional digital model 200 of the patient's teeth above the predefined boundary being extended by a certain thickness. In one embodiment the predefined boundary may be the gum line, in a further embodiment the predefined boundary may also be a boundary located above the gum line (i.e. close to the crown), in a further embodiment the predefined boundary may also be a boundary located below the gum line (i.e. close to the root).
Next, a window 310a larger than the accessory size is formed at a predetermined orientation on the first three-dimensional digital model 300a-1, resulting in the three-dimensional digital model 300a-2 of the accessory mounting template as shown in FIG. 3B.
Then, the three-dimensional digital model 320a of the accessory is fitted in a predetermined orientation within the window 310a of the three-dimensional digital model 300a-2 of the accessory mounting template, and a weak connection (not shown) is provided between the edge of the window 310a and the three-dimensional digital model 320a of the accessory mounting template, resulting in the three-dimensional digital model 300a-3 of the accessory mounting template assembly as shown in fig. 3C. In yet another embodiment, the three-dimensional digital model of the accessory having the weak link is pre-designed and can be directly mounted in a predetermined orientation within the window 310a of the three-dimensional digital model of the accessory mounting template 300a-2 to obtain the three-dimensional digital model of the accessory mounting template assembly 300 a-3.
A weak link is a relatively weak link that has a mechanical strength that is lower than the mechanical strength of the component itself (referred to herein as the accessory mounting template and the accessory) and can be broken with a relatively small force without causing damage to the component itself. Such as thinner connections, or spaced connections, etc.
Referring to fig. 4, a weak connection between an accessory and an accessory mounting template is schematically illustrated in one embodiment, with spaced point connections 330a between the accessory 320a and the window 310a, whereby the accessory mounting template holds and positions the accessory 320 a.
The primary function of the attachment mounting template is to hold and position the attachment so that when the attachment mounting template assembly is worn on a patient's tooth, the attachment is in a predetermined orientation on the surface of the patient's tooth, thereby achieving accurate mounting of the attachment. Therefore, the accessory mounting template has low requirements on mechanical performance. In one embodiment, in addition to the window 310a, a plurality of other hollowed-out portions may be provided on the three-dimensional digital model 300a-2 of the accessory mounting template to save the material for manufacturing the accessory mounting template. It will be appreciated that the shapes and distribution of these hollowed-out portions may be arranged arbitrarily, for example, the hollowed-out portions may be circular and the distribution may be uniform. Therefore, the case where the shell-like accessory mounting template includes the complete housing, also includes the case where a plurality of hollowed-out portions are provided.
In yet another embodiment, the three-dimensional digital model of the attachment mounting template of the lattice-like structure (e.g., truss structure) can be generated directly based on the outer surface of the three-dimensional digital model of the patient's teeth without first generating a complete shell-like three-dimensional digital model and then hollowing it out.
In yet another embodiment, the following method may also be used to generate a three-dimensional digital model of an attachment mounting template assembly based on the three-dimensional digital model 200 of the patient's teeth.
First, a scaled-up three-dimensional digital model 320b of the attachment is added to the three-dimensional digital model 200 of the patient's teeth in a predetermined orientation, resulting in a second three-dimensional digital model 300b-1 as shown in FIG. 5A.
Next, the three-dimensional digital model 300B-2 of the shell-shaped accessory mounting template shown in fig. 5B is obtained by outwardly expanding a certain thickness based on the outer surface of the portion of the second three-dimensional digital model 300B-1 above the predefined boundary line, and the accessory receiving cavity 330B is correspondingly formed thereon.
Then, the three-dimensional digital model of the accessory is assembled in the accessory accommodating cavity 330b of the three-dimensional digital model 300b-2 of the accessory mounting template according to a predetermined orientation, and weak connection is added between the accessory accommodating cavity 330b and the three-dimensional digital model of the accessory, so that the three-dimensional digital model of the accessory mounting template assembly can be obtained.
Referring to FIG. 5C, a cross-section of the accessory receiving portion 330b of the three-dimensional digital model 300b-3 of the accessory mounting template assembly is schematically illustrated, the three-dimensional digital model 310b of the accessory is received within the accessory receiving portion 330b of the three-dimensional digital model 300b-2 of the accessory mounting template, and the three-dimensional digital model 310b of the accessory and the three-dimensional digital model 300b-2 of the accessory mounting template are secured to each other by a weak connection 340b, such that the accessory mounting template is capable of holding and positioning the accessory.
It will be appreciated in light of the present disclosure that many variations of the method of generating the three-dimensional digital model of the attachment mounting template assembly based on the three-dimensional digital model 200 of the patient's teeth, and many variations of the attachment mounting template and the structure of the attachment, are possible and are not further described herein.
At 105, the three-dimensional digital model of the accessory mounting template assembly is used to control the 3D printing device to fabricate the accessory mounting template assembly.
Currently, a variety of 3D printing technologies have been introduced into large-scale commercial applications, such as stereolithography (stereolithography), jet printing, and fused deposition modeling, and these 3D printing technologies can be used to fabricate the accessory mounting template assembly.
In one embodiment, different portions may be printed with different materials, for example, the attachment mounting template is printed with a first material, the weak link is printed with a second material, and the attachment is printed with a third material. In some cases, it is of high practical value to print different parts in different materials. For example, the attachment can be printed with a material that has a higher hardness after curing to ensure its performance throughout the dental appliance cycle; for another example, the weak link may be printed with a material that is brittle when cured to facilitate detachment of the attachment mounting template from the attachment after the attachment is affixed to the tooth surface.
In one embodiment, the accessory mounting template assembly with the adhesive coated on the bottom surface of the accessory is worn on the teeth of a patient, after the adhesive is cured, the weak connection between the accessory and the accessory mounting template is broken, and after the accessory and the accessory mounting template are separated from each other, the accessory mounting template is removed, so that the accessory is mounted.
In yet another embodiment, the attachment is formed with a hollow portion extending from the top surface to the bottom surface, after the attachment mounting template assembly is applied to the patient's teeth, an adhesive is injected into the hollow portion and spreads over the bottom surface of the attachment, after the adhesive is cured, the weak connection between the attachment and the attachment mounting template is broken, and after the attachment and the attachment mounting template are separated from each other, the attachment mounting is completed by removing the attachment mounting template.
Referring to fig. 6A, a cross-sectional shape of an attachment 320c in one embodiment of the present application is schematically illustrated. Hollow 321c of accessory 320c includes a channel extending from the top surface to the bottom surface, the bottom surface of which is formed with a sharp wall 323c protruding from the edge to enclose the adhesive inside the accessory, and the bottom surface of which is slightly recessed to form an adhesive storage chamber 325c to ensure that the adhesive substantially spreads over the bottom surface of the accessory 320c, thereby ensuring the bonding firmness of the accessory. In one embodiment, substantially the entire bottom surface of the attachment is recessed to ensure that the adhesive is spread over substantially the entire bottom surface, for example, the recessed portion may comprise more than 70%, even more than 80%, even more than 90% of the area of the bottom surface. In one embodiment, the surface of the concave part on the bottom surface of the accessory can be provided with a rugged structure to increase the contact area with the adhesive and further enhance the bonding firmness.
Referring to fig. 6B, a cross-sectional shape of an accessory 320d in yet another embodiment of the present application is schematically illustrated. Hollow portion 321d of fitment 320d includes a channel extending from the top surface to the bottom surface, and the bottom surface is formed with a slightly concave curved surface to form an adhesive storage chamber 325d to ensure the bonding firmness of fitment 320 d.
Referring to fig. 6C, a cross-sectional shape of an attachment 320e in a further embodiment of the present application is schematically illustrated. The hollow portion 321d of the attachment 320e is substantially funnel-shaped.
Referring to fig. 6D, a cross-sectional shape of an accessory 320f in another embodiment of the present application is schematically illustrated. The attachment 320f is substantially hollow, with a hollow 321f being large.
It will be appreciated in the light of the present application that, in addition to attachments for cementing to a tooth surface, interacting with shell-like dental appliances to provide an auxiliary force system for dental correction, the attachments of the present application may also be other attachments for cementing to a tooth surface, such as tongue buttons (brackets), and the like.
