In the above operating environment, according to a first aspect of the present embodiment, a method for determining a gap required for orthodontic treatment is provided. Fig. 2 shows a flow diagram of the method, which, with reference to fig. 2, comprises:
s201: determining a first gap value required for orthodontic treatment, wherein the first gap value is indicative of a degree of crowding of a patient's dentition;
s202: determining a second gap value required for orthodontic correction of the tooth, wherein the second gap value is indicative of an amount of gap required to flatten the Spee curve;
s203: determining a third gap value required for orthodontic treatment, wherein the third gap value is used for indicating a difference relationship between the current dental arch prominence and the standard dental arch prominence of the patient;
s204: determining a fourth gap value required for orthodontic treatment, wherein the fourth gap value is used for indicating an amount of molar movement required for converting the current occlusion state of the patient to a standard occlusion state; and
s205: and determining the total gap required for orthodontic treatment of the patient according to the first gap value, the second gap value, the third gap value and the fourth gap value.
As described in the background above, currently, in orthodontic procedures, a doctor needs to consider whether there is a position for placing a tooth in a desired position if he wants to move the patient's tooth to an aesthetic position. Therefore, in the orthodontic treatment, the doctor needs to calculate the gap required for orthodontic treatment, which is equivalent to an intermediate parameter, and the doctor can design the treatment plan and select a specific treatment device by referring to the intermediate parameter. However, there is no method for determining the gap required for orthodontic treatment, and most doctors roughly calculate the gap required for orthodontic treatment by experience, and determine a design scheme and select a specific treatment device by experience.
In view of the above technical problem, the present embodiment proposes a method for determining a gap required for orthodontic treatment, which first determines a first gap value required for orthodontic treatment to indicate a degree of crowding of a patient's dentition. Wherein the dentition crowding level represents the difference between the patient's existing dentition length and the due dentition length, which is the sum of the widths of all teeth.
A second gap value indicative of the amount of gap required to flatten the Spee curve for orthodontic treatment is then determined. Wherein the amount of clearance required to flatten the Spee curve refers to the local space (i.e., clearance) required to flatten the Spee curve. Second, a third gap value indicative of a differential relationship between the patient's current and standard arch prominences is determined as required for orthodontic treatment. In which, if the mouth of the patient is not protruded or dented, it is necessary to ensure that the teeth of the patient are not protruded or dented. Thus, in this embodiment, it is desirable to determine the differential relationship between the patient's current and standard arch prominence.
Further, since the occlusion of the individual molars has certain requirements and standards, the present embodiment also requires determining a fourth gap value required for orthodontic correction to indicate the amount of molar movement required to transition the patient's current occlusion to the standard occlusion. Finally, the total gap required for orthodontic correction of the patient is determined according to the first gap value, the second gap value, the third gap value and the fourth gap value. The unit of the first gap value, the second gap value, the third gap value and the fourth gap value can be millimeters. In this way, four gap values required for orthodontic correction can be determined, and the total gap required for orthodontic correction can be accurately determined according to the four gap values. Thus, the present embodiments provide a method for determining a gap required for orthodontic treatment, which can assist a doctor in designing a treatment plan and selecting a specific treatment device. Further solves the technical problems that the prior art lacks a method for determining the gap required by tooth orthodontics and cannot assist doctors in designing treatment schemes and selecting specific treatment devices.
Optionally, the operation of determining a first gap value required for orthodontic treatment comprises: determining a current arch length of the patient; determining a width of each tooth of the patient; determining a target arch length required by the patient according to the width of each tooth of the patient; and determining a first gap value based on the current arch length and the target arch length.
Specifically, referring to fig. 3A and 3B, a current arch length of the patient is first determined, then a width of each tooth of the patient is determined, and a target arch length required by the patient is determined according to the width of each tooth of the patient, wherein the target arch length is equal to the sum of all tooth widths. Finally, a first gap value is determined based on the current arch length and the target arch length. For example, a difference between the current arch length and the target arch length is calculated, and the calculated difference is taken as the first gap value. Wherein the first clearance value is negative when the existing dentition length is less than the due dentition length and positive when the existing dentition length is greater than the due dentition length. In this way, the first gap value required for orthodontic correction can be determined quickly and accurately.
Optionally, determining a Spee curve of the patient's dentition; determining a depth of the Spee curve; and determining a second gap value based on the depth of the Spee curve.
Specifically, referring to FIG. 4, the Spee curve of a patient's dentition is measured and the depth of the Spee curve is determined. In the process of determining the depth of the Spee curve, a straight line is firstly used for connecting two end points of the Spee curve, then the vertical distance between the lowest point of the Spee curve and the straight line is determined, the determined vertical distance is the depth of the Spee curve, and finally the depth of the Spee curve is determined as a second gap value required by orthodontic treatment. In this way, the second gap value required for orthodontic correction can be determined quickly and accurately.
Optionally, the operation of determining a third gap value required for orthodontic treatment comprises: determining a current arch prominence of the patient; and determining a third gap value according to the current dental arch prominence and a preset standard dental arch prominence.
Specifically, if the mouth of the patient is not protruded or dented, it is required to ensure that the teeth of the patient are not protruded or dented, and thus it is required to determine the current dental arch prominence of the patient, and then compare the current dental arch prominence with a preset standard dental arch prominence, thereby determining a third gap value required for orthodontic treatment. Wherein the second gap value is a positive value in the event that the current arch prominence is less than the standard arch prominence. In the case where the current arch prominence is greater than the standard arch prominence, the second gap value is a negative value. In this way, the third gap value required for orthodontic correction can be determined quickly and accurately.
Optionally, the operation of determining the current arch prominence of the patient comprises: determining a straight line between a first preset point located in the maxilla of the patient and a second preset point located in the mandible of the patient; determining a first vertical distance of an incisor in the patient's upper jaw relative to a straight line; determining a second perpendicular distance of incisors in the patient's mandible relative to the straight line; and determining the current arch prominence of the patient according to the first vertical distance and the second vertical distance.
In particular, for example and without limitation, a first predetermined point located in the patient's maxilla, such as the connection point of the maxilla to the nose, and a second predetermined point located in the patient's mandible, such as the patient's chin, may be predefined. Referring to fig. 5A and 5B, in the present embodiment, a straight line between the first preset point and the second preset point is first determined, then a first vertical distance of the incisors in the patient's upper jaw with respect to the straight line is determined, and a second vertical distance of the incisors in the patient's lower jaw with respect to the straight line is determined. Finally, the current arch prominence of the patient is determined according to the first vertical distance and the second vertical distance. Illustratively, standard arch prominence defines a standard vertical distance of the maxillary central incisors from a straight line in the range of 5.0-9.4 mm, with the maxillary central incisors having an optimal vertical distance of 7.2 mm from a straight line. The standard arch prominence defines that the standard vertical distance of the incisors in the lower jaw relative to the straight line is 2.8-7.0 mm, and the optimal vertical distance of the incisors in the lower jaw relative to the straight line is 4.9 mm.
Optionally, the operation of determining a fourth gap value required for orthodontic treatment comprises: determining a buccal apex location of a first molar of a maxilla of the patient; determining a buccal sulcus position of a mandibular first molar of the patient; and determining a fourth gap value based on the buccal cusp position and the buccal sulcus position.
Specifically, in the standard occlusal state, the buccal cusp position of the first molar of the upper jaw of the human needs to be directed to the buccal sulcus position of the first molar of the lower jaw. Wherein, the first molar is also called six-age tooth or six-age tooth. In this embodiment, it is necessary to determine the buccal cusp position of the upper first molar and the buccal sulcus position of the lower first molar of the patient, then determine the relative positional relationship between the buccal cusp position of the upper first molar and the buccal sulcus position of the lower first molar, and determine the fourth gap value required for orthodontic treatment according to the relative positional relationship. Wherein the fourth gap value is negative in a case where a buccal apex position of the upper jaw first molar is located rearward of a buccal sulcus position of the lower jaw first molar. The fourth gap value is positive when the buccal cusp position of the maxillary first molar is located forward of the buccal sulcus position of the mandibular first molar. In this way, the fourth gap value required for orthodontic correction can be determined quickly and accurately.
Further, referring to fig. 1, according to a second aspect of the present embodiment, there is provided a storage medium. The storage medium comprises a stored program, wherein the method of any of the above is performed by a processor when the program is run.
It should be noted that, for simplicity of description, the above-mentioned method embodiments are described as a series of acts or combination of acts, but those skilled in the art will recognize that the present invention is not limited by the order of acts, as some steps may occur in other orders or concurrently in accordance with the invention.

Through the above description of the embodiments, those skilled in the art can clearly understand that the method according to the above embodiments can be implemented by software plus a necessary general hardware platform, and certainly can also be implemented by hardware, but the former is a better implementation mode in many cases. Based on such understanding, the technical solutions of the present invention may be embodied in the form of a software product, which is stored in a storage medium (e.g., ROM/RAM, magnetic disk, optical disk) and includes instructions for enabling a terminal device (e.g., a mobile phone, a computer, a server, or a network device) to execute the method according to the embodiments of the present invention.
