Description

Technical Field

[0001] The present invention relates to the technical field of dental orthodontic appliances, and in particular to a transparent orthodontic appliance and an orthodontic force detection method. Background Art

[0002] As a new correction technology, transparent braces are used for orthodontic treatment of patients with malocclusion. They are widely favored by patients because they do not have the wires and brackets used in traditional correction, are comfortable to wear, and do not affect the appearance. This invisible correction technology inherits the traditional concept of malocclusion correction and is a perfect combination of modern stomatology, computer-aided three-dimensional diagnosis, personalized design and digital molding technology. When using invisible correction technology, the doctor generates a digital dental model based on the patient's individual dentition. The orthodontist uses special software to formulate a treatment plan, design the final tooth arrangement goal and tooth movement steps, and output the modeling after each step of tooth movement according to the orthodontic plan to make a series of personalized transparent braces. Patients gradually complete the correction by wearing them on time and replacing them regularly. The transparent braces are made of a human-safe medical resin film, which is wrapped around the teeth and exerts a certain orthodontic force on the teeth. It is recognized by consumers for its comfort and beauty.

[0003] Currently, the collection of patient dental data mainly uses traditional impression-taking and digital mouth scanning technology. For patients who use clear braces, a series of clear braces to be worn in the future (usually 3-6 months) are designed after a mouth scan or impression-taking. Patients change their clear braces approximately every week. During this period, they can only be replaced according to the wearing time recommended by the doctor. Patients cannot intuitively monitor the stress state of the clear braces. If any abnormal problems occur during the process, they can only be resolved when the patient notices discomfort and actively seeks out a doctor. Real-time monitoring cannot be achieved, which often leads to the deviation of treatment from expectations, subsequent scrapping of clear braces, and prolonged treatment time.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] The purpose of the present invention is to provide a transparent appliance and an orthodontic force detection method to solve the problems existing in the above-mentioned prior art, so as to facilitate timely observation of the orthodontic condition of the transparent appliance so as to take timely measures.

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Embodiment 1

[0032] This embodiment provides a transparent appliance 1, see Figure 1 , including an appliance body 11 and at least one stress color-developing component 12. The stress color-developing component 12 is arranged on the appliance body 11 to correspond to the outer side of the tooth to be orthodontic. The stress color-developing component 12 is used to display different colors under the action of different sizes of orthodontic forces on the tooth to be orthodontic.

[0033] By arranging a stress color-developing component 12 on the outer side of the orthodontic appliance body 11 corresponding to the tooth to be orthodontically treated, as the position of the tooth to be orthodontically treated is orthodontically adjusted, the orthodontic force between the orthodontic appliance body 11 and the tooth to be orthodontically treated gradually decreases, thereby gradually reducing the orthodontic force exerted on the stress color-developing component 12 and gradually changing its displayed color. The change in the orthodontic force can be judged based on the change in the displayed color, which facilitates timely and intuitive observation of the orthodontic condition of the transparent appliance 1 so as to respond in a timely manner.

[0034] Furthermore, the number of stress color display components 12 can be determined according to the number of teeth to be orthodontically treated, thereby facilitating the determination of the orthodontic condition of each tooth to be orthodontically treated.

[0035] In the optional scheme of this embodiment, it is more preferred that the transparent braces 1 provided in this embodiment also include a control component 13, and the control component 13 is used to be arranged on the braces body 11 for corresponding to the outer side of at least one normal tooth, and the control component 13 is used to show the display color of the stress color-developing component 12 when it is not affected by the orthodontic force of the tooth to be orthodontic; by comparing the displayed color of the stress color-developing component 12 with that of the control component 13, the color change of the stress color-developing component 12 can be judged, thereby facilitating the judgment of the orthodontic situation.

[0036] Among the optional solutions of this embodiment, it is more preferred to refer to Figure 2 The stress color-developing component 12 and the control component 13 both include a color-developing layer 14 and a transparent film layer 15 which are sequentially arranged away from the appliance body 11; the color-developing layer 14 is fixedly connected to the outer side of the appliance body 11, and the transparent film layer 15 is used to deform under the action of orthodontic forces of different sizes on the teeth to be orthodontically deformed to show different transparencies, so that the displayed color of the color-developing layer 14 can pass through the transparent film layer 15 and be displayed to the outside world in different degrees, and the orthodontic condition can be judged by observing the displayed colors of different degrees, i.e., depths.

[0037] In the optional scheme of this embodiment, it is more preferred that the stress color-developing component 12 and the control component 13 also include a transparent elastic layer 16, and the transparent elastic layer 16 is arranged between the color-developing layer 14 and the transparent film layer 15 and connected to the transparent film layer 15. The transparent film layer 15 is used to deform under the action of orthodontic forces of different sizes on the teeth to be orthodontically treated to show different transparencies and cause the transparent elastic layer 16 to undergo elastic deformation. At the beginning of orthodontics, the tensile deformation of the transparent film layer 15 is the largest. As the orthodontics progresses, the tensile deformation of the transparent film layer 15 gradually decreases, and the deformation is restored with the assistance of the elastic restoring force of the transparent elastic layer 16 to adjust the transparency of the transparent film layer 15.

[0038] In the optional scheme of this embodiment, it is more preferred that the stress color-developing component 12 and the control component 13 also include a transparent protective layer 17 fixedly arranged on the side of the transparent film layer 15 away from the transparent elastic layer 16, and the transparent protective layer 17 is fixedly connected to the orthodontic device body 11; the transparent protective layer 17 is used to protect the transparent film layer 15 from external damage, wherein the transparent elastic layer 16 and the transparent film layer 15 are fixedly bonded and arranged between the color-developing layer 14 and the transparent protective layer 17.

[0039] In the optional scheme of this embodiment, it is more preferred that the color developing layer 14, the transparent protective layer 17 and the orthodontic device body 11 are all made of medical polymer materials, and the color developing layer 14 includes a color coating layer, wherein the color coating layer can be red or blue coating.

[0040] Among the optional schemes of this embodiment, it is more preferred that the transparent film layer 15 is made of PVA / laponite material, that is, a nano-composite material mixed with polyvinyl alcohol (PVA) and Laponite (a layered silicate material). When the transparent braces 1 are subjected to stress, the transparent film layer 15 will deform to form a rough structure with cracks and creases, which greatly improves the light scattering performance and makes it opaque. When the transparent braces 1 are not subjected to stress, the transparent film layer 15 will return to a flat and smooth structure and gradually regain high transparency.

[0041] In the optional solution of this embodiment, more preferably, the transparent elastic layer 16 is made of PDMS material, that is, polydimethylsiloxane material.

[0042] Embodiment 2

[0043] This embodiment provides an orthodontic force detection method, based on the transparent appliance in the first embodiment, comprising the following steps:

[0044] Before the transparent appliance body 11 is worn, the stress color developing component 12 is not subjected to the orthodontic force of the tooth to be orthodontized, and the stress color developing component 12 displays the first color, and the control component 13 is not subjected to the orthodontic force of the tooth to be orthodontized, and the control component 13 displays the first color;

[0045] After the transparent appliance body 11 is worn, the stress color developing component 12 is subjected to the orthodontic force of the tooth to be orthodontically treated, and the stress color developing component 12 displays a second color;

[0046] The orthodontic force exerted on the tooth to be orthodontically treated by the stress color-developing component 12 gradually decreases as the position of the tooth moves, and the color displayed by the stress color-developing component 12 starts to change from the second color and gradually approaches the first color. The magnitude of the orthodontic force is determined according to the degree of change of the second color, that is, the magnitude of the orthodontic force is determined by comparing the color displayed by the stress color-developing component 12 with the first color displayed by the control component 13.

[0047] Specifically, the relationship curve between the color development degree of the stress color development component 12 and the magnitude of the orthodontic force can be determined in advance through experiments, so as to facilitate the subsequent rough judgment of the magnitude of the orthodontic force based on the color development situation.

[0048] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as limiting the present invention.
