Description

Technical Field

[0002] Malocclusion has a relatively high morbidity rate in children's growth and development, and there are multiple factors causing malocclusion. Invisible orthodontics often requires tipping the posterior teeth too high to correct crossbite or reconstruct occlusion in a timely manner. Traditional tipping can be achieved by forming cavities on the surface of the appliance / cavities with filling, or bonding a tipping outside the appliance.

[0003] Most tips are of a fixed shape, difficult to adapt to different patients, and the orthodontic effect is not good. Summary of the Invention

[0004] The purpose of the present invention is to provide a dental appliance assembly, a method for determining an appliance, and an electronic device, which are helpful to improve the accurate adjustment ability of the appliance for tooth displacement and occlusion relationship.

[0005] In a first aspect, the present invention provides a dental appliance assembly, including a first appliance and a second appliance disposed opposite to each other. The first appliance includes an appliance body and an occlusion structure located on the occlusal surface of the appliance body. The occlusion structure is used to adjust the relative positional relationship of the upper and lower teeth, and at least one of the height, shape, and surface slope of the contact surface of the occlusion structure with the second appliance is different in

[0006] a first direction, where the first direction is one or more of the sagittal direction, the vertical direction, and the horizontal direction.

[0007] A possible implementation is that at least one of the height, shape, and surface slope of the occlusion structure in the first direction is different to achieve the orthodontic target or orthodontic force requirement for specific teeth in a timely manner.

[0008] A possible implementation is that the orthodontic target is tooth intrusion, and the height of the occlusion block at the position of the tooth to be intruded is higher than other parts of the occlusion block.

[0009] A possible implementation is that the orthodontic target is tooth extrusion, and the height of the occlusion block at the position of the tooth to be extruded is lower than other parts of the occlusion block.

[0010] A possible implementation is that the occlusion structure is a tip or the thickness of the diaphragm on the first appliance is greater than the structure formed at other positions.

[0056] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0057] Malocclusion has a high incidence rate in children's growth and development, and there are multiple factors that cause malocclusion. Invisible braces often need to raise the posterior teeth with jaw pads to achieve crossbite correction or occlusion reconstruction. Traditional jaw pads can form a cavity / filled cavity on the surface of the appliance (the filling body can be fixed on the teeth or separated), or a jaw pad can be bonded outside the appliance. Most jaw pads have a fixed shape, and a few jaw pads take into account the cusp structure of the opposing teeth, so that their surfaces are designed to match the opposing teeth, so as to better achieve the locking of the upper and lower jaws. The current jaw pads are basically designed according to the bite record obtained by the clinical appliance through oral scanning or silicone to determine the position relationship between the upper and lower jaws, but this upper and lower jaw relationship may not necessarily meet the treatment purpose in some treatments, especially in some fine jaw position designs, lacking the ability to accurately adjust the jaw position through further design and control of the jaw pad height and surface slope. The essence of a jaw pad is to form a specific protruding structure on the teeth or orthodontic appliances, thereby changing the occlusal relationship between the upper and lower jaws, forming a treatment for jaw position adjustment, providing a spatial channel for orthodontic treatment, or by changing the occlusal state of the teeth and exerting bite force on specific teeth to produce the effect of depressing the teeth.

[0058] The current jaw pads are designed based on the bite record obtained by oral scanning or silicone through clinical orthodontic appliances to determine the position relationship between the upper and lower jaws. However, this upper and lower jaw relationship may not meet the treatment objectives in some treatments. In particular, in some sophisticated jaw position designs, there is a lack of ability to accurately adjust the jaw position through further design and control of the jaw pad height and surface inclination.

[0059] These fine adjustments cannot be simply determined by the positional relationship between the upper and lower jaws determined by the bite record obtained through oral scanning or silicone before clinical treatment. Instead, further design is required on this basis to form a specific upper and lower jaw positional relationship, occlusal relationship, and bite force relationship by adjusting the height, surface slope, and shape of the jaw pad along the dental arch. On the basis of obtaining the clinical jaw position, the jaw pad with directional adjustment function is formed by controlling the distribution of the jaw pad height and surface slope along the dental arch.

[0060] The present embodiment provides an occlusal structure, an invisible braces and a method for determining the braces. The occlusal structure or the invisible braces with an integrated occlusal structure used has at least one of the distribution of height, shape and surface slope relative to the dental arch, so that the occlusal structure has a directional adjustment function. On the basis of the existing jaw pad, the ability of the jaw pad to accurately adjust the jaw position and occlusal relationship is further improved.

[0061] like Figure 1 As shown, this embodiment provides a method for generating an appliance, which includes:

[0062] S1: Obtain the patient's first maxillomandibular relationship.

[0063] S2: Determine a corrective appliance according to the first maxillomandibular relationship, wherein the corrective appliance includes an occlusal structure, and a second maxillomandibular relationship formed by the occlusal structure in a first direction is different from the first maxillomandibular relationship.

[0064] In one embodiment, when the outer surface of the orthodontic appliance is in contact with the opposing jaw, a second maxillo-mandibular relationship is formed.

[0065] In the present application, the first maxillomandibular relationship may be a maxillomandibular relationship with an unspecified jaw position, or may be a maxillomandibular relationship with a specified jaw position.

[0066] In a possible implementation manner, the first maxillomandibular relationship can be obtained through an oral model acquisition method such as three-dimensional oral scanning or occlusal silicone mold model recording.

[0067] In a possible implementation, the first maxillomandibular relationship may be a maxillomandibular position relationship specified by a doctor based on an oral model of the patient and pulled by the patient's muscle movements or fixed by auxiliary measures.

[0068] In a possible implementation, the first upper and lower jaw relationship may also be a positional relationship that is manually adjusted using a virtual model of the upper and lower jaws in a virtual environment such as a computer.

[0069] In another possible implementation manner, the first maxillomandibular relationship may also be a maxillomandibular relationship obtained by simulation based on a software algorithm.

[0070] In view of medical treatment plans, especially oral treatment plans such as orthognathic orthodontics, factors such as the patient's oral structure, the type and degree of malocclusion lesions, and the patient's individual oral physiological characteristics may be comprehensively considered. Therefore, for some patients, the first maxillomandibular relationship may not necessarily meet the treatment objectives in certain medical treatments. Especially in some delicate jaw position designs, precise adjustment of the jaw position is required.

[0071] In some embodiments, the second maxillomandibular relationship may be the maxillomandibular position relationship expected to be adjusted on the basis of the first maxillomandibular relationship during the treatment process.

[0072] A possible implementation method is to obtain the second maxillomandibular relationship based on the adjustment of the occlusal structure in the first direction.

[0073] A possible implementation method is that the first direction includes one or more of the sagittal direction, the vertical direction, and the horizontal direction.

[0074] In the specific implementation process, there are various ways to change the occlusal structure in the first direction to achieve the second occlusal relationship.

[0075] A possible implementation method is that the occlusal structure includes at least one of the relative height, shape, and surface slope distribution of the dental arches. A possible implementation method is that the occlusal structure includes a change in at least one of the relative height, shape, and surface slope distribution of the dental arches.

[0076] A possible implementation method is that the surface of the occlusal structure includes at least one of the following:

[0077] At least partially continuously distributed; at least partially discretely distributed; at least partially linearly distributed; at least partially linearly distributed.

[0078] A possible implementation method is that along the sagittal direction, at least part of the occlusal structure has a higher height closer to the posterior teeth side; or

[0079] Along the sagittal direction, at least part of the occlusal structure has a lower height closer to the posterior teeth side.

[0080] A possible implementation method is that the occlusal structure includes at least one of the relative height, shape, and surface slope distribution of the dental arches.

[0081] A possible implementation method is that the first direction includes one or more of the sagittal direction, the vertical direction, and the horizontal direction.

[0082] A possible implementation method is that the height of the occlusal structure is 0.5 - 1 mm.

[0083] A possible implementation method is that the height change amount of the occlusal structure satisfies 0.5 - 1 mm.

[0084] Optionally, the second maxillomandibular relationship may have only a slight difference from the first maxillomandibular relationship. For example, there is no difference in tooth No. 4, while there is a 1 mm difference in tooth No. 7.

[0085] In one possible implementation, the occlusal structure is arranged along the dental arch direction and covers at least one tooth.

[0086] In one possible implementation, the occlusal structure is provided on the left jaw and the right jaw.

[0087] In one possible implementation, the slope distribution includes: the left jaw and the right jaw having the same horizontal inclination.

[0088] In one possible implementation, the occlusal structure can be a part of the orthodontic appliance, or an accessory added to the orthodontic appliance, or a structure such as a bite plate or a jaw plate that is used in cooperation with the orthodontic appliance.

[0089] The occlusal structure of the present application will be illustrated below by taking a bite plate as an example.

[0090] In one possible implementation, the structure of the occlusal structure may include a distribution structure of at least one of the height, shape, and surface slope relative to the dental arch.

[0091] In one possible implementation, based on the first maxillomandibular relationship, a further precisely adjusted second maxillomandibular relationship is designed, so that the second maxillomandibular relationship performs a directional adjustment of the jaw position and occlusal relationship relative to the first maxillomandibular relationship, or generates a tooth biting force of the upper and lower jaws different from the first upper and lower jaw relationship to achieve a specific medical treatment goal. Thus, the second maxillomandibular relationship better meets the personalized needs of different patients, formulates a more precise medical treatment plan for the patients, and improves the effect of medical treatment.

[0092] In one possible implementation, in terms of the positional relationship, there may be the following various situations between the second maxillomandibular relationship and the first maxillomandibular relationship.

[0093] In one possible implementation, in the side view direction, the occlusal plane of the second maxillomandibular relationship rotates clockwise or counterclockwise relative to the occlusal plane of the first maxillomandibular relationship.

[0094] In one possible implementation, in the front view direction, the occlusal plane of the second maxillomandibular relationship rotates clockwise or counterclockwise relative to the occlusal plane of the first maxillomandibular relationship.

[0095] In one possible implementation, in the occlusal plane view direction, the occlusal plane of the second maxillomandibular relationship rotates clockwise or counterclockwise relative to the occlusal plane of the first maxillomandibular relationship.

[0096] In a possible implementation, in the direction of the occlusal plane view, the occlusal plane of the second maxillomandibular relationship is translated and offset relative to the occlusal plane of the first maxillomandibular relationship in at least one of the sagittal, vertical, and horizontal directions.

[0097] In a possible implementation, in addition to the above positional relationship, the second maxillomandibular relationship may also include other positional relationships obtained by further adjustment on the first maxillomandibular relationship.

[0098] In a possible implementation, according to the conditions of different patients and different medical treatment purposes, the position of the second maxillomandibular relationship relative to the first maxillomandibular relationship can be flexibly adjusted.

[0099] In a possible implementation, by adjusting the height, shape, and surface slope distribution of the occlusal structure relative to the dental arch, the occlusal structure is formed into a structure with at least a partially changing height trend, so as to utilize the change of the height and / or surface slope of the occlusal structure to adjust the first maxillomandibular relationship to the second maxillomandibular relationship, forming an adjusted maxillomandibular position relationship, occlusal relationship, or bite force relationship.

[0100] In a possible implementation, at least one of the height, shape, and surface slope distribution of the occlusal structure relative to the dental arch. For example, the occlusal structure is formed into at least a partially continuous distribution or at least a partially discrete distribution; or at least one of the height, shape, and surface slope distribution of the occlusal structure relative to the dental arch is adjusted to form the occlusal structure into at least a partially linear distribution or at least a partially non-linear distribution.

[0101] In a possible implementation, when the occlusal structure is at least partially continuously distributed, the adjustment of the occlusal structure is applied to the dental arch in at least a partially continuous manner, forming at least a partially smooth height change, which is suitable for situations requiring progressive adjustment, so that a more natural and progressive jaw position change can be achieved. When the occlusal structure is at least partially discretely distributed, the adjustment method of the occlusal structure is based on at least partially discrete points or regions as units, forming at least a partially discontinuous height change, which is suitable for situations including concentrating on adjusting specific regions, so that local adjustment of teeth can be achieved.

[0102] In a possible implementation, when the occlusal structure is at least partially linearly distributed, the occlusal structure can be at least partially uniform or increased or decreased according to at least a partially specific ratio. It is suitable for situations requiring uniform adjustment.

[0103] In a possible implementation, when the occlusal structure is at least partially non-linearly changed, it can be adjusted more flexibly according to the needs of specific teeth or regions, which is suitable for situations requiring personalized and differentiated adjustment and is closer to the actual condition of the patient's oral cavity.

[0104] A possible implementation is to adjust the occlusion structure so that it is at least partially higher in height closer to the posterior tooth side along the sagittal direction; or to adjust the occlusion structure so that it is at least partially lower in height closer to the posterior tooth side along the sagittal direction.

[0105] A possible implementation is that the overall height change trend of the occlusion structure is at least partially continuously variable, so as to effectively balance the biting force and accurately control the jaw position.

[0106] A possible implementation is that, according to the conditions of different patients, the occlusion structure can be set on the left jaw, or the right jaw, or both the left and right jaws; and can be set on the lower jaw, or the upper jaw, or both the upper and lower jaws. The size and range can be adjusted according to actual needs and are not limited here.

[0107] A possible implementation is that, according to the conditions of different patients, the occlusion structures set on the left jaw and the right jaw can have the same horizontal inclination, or different inclinations can be set respectively according to the conditions of the left and right jaws.

[0108] A possible implementation is that the occlusion structure is set along the dental arch direction and covers a range of at least 1 tooth. Optionally, the occlusion structure is set along the dental arch direction and can cover the range of teeth No. 4 - 7. Of course, the occlusion structure can also adopt a discrete structure and only set some of the tooth regions to achieve the effect of precise control.

[0109] There can be various ways to set the occlusion structure on the orthodontic appliance.

[0110] A possible implementation is to form a convex cavity structure or a solid structure with at least one change in height, shape, and surface slope relative to the dental arch on the invisible orthodontic appliance, so that the cavity structure or the solid structure constitutes the occlusion structure;

[0111] A possible implementation is to fix the occlusion structure on the upper surface of the invisible orthodontic appliance, and the occlusion structure has at least one change in height, shape, and surface slope relative to the dental arch.

[0112] A possible implementation is that the occlusion structure can be integrated on the invisible orthodontic appliance or be an additional occlusion structure.

[0113] A possible implementation is that when the occlusion structure is a cavity structure, the weight of the occlusion structure can be reduced to improve the wearing comfort. In addition, the cavity can be filled with a solid, such as materials like photocuring resin and gel, to improve its structural strength and ensure sufficient stability and support.

[0114] A possible implementation is that when the occlusion structure is additionally set, its material can also be photocuring resin, gel, etc., and it can also be a solid structure or a cavity structure.

[0115] This embodiment also provides an occlusal structure, which has changes in height, shape and surface inclination relative to the dental arch. When the occlusal structure is set on the orthodontic appliance, the outer surface of the orthodontic appliance and the outer surface of the opposing orthodontic appliance / teeth are in contact with each other, forming a second maxillomandibular relationship that is different from the first maxillomandibular relationship.

[0116] In one possible implementation, the first maxillomandibular relationship is a specified maxillomandibular position relationship obtained by traction by the patient's muscle movement or fixed by auxiliary measures, or is an maxillomandibular position relationship obtained by manual adjustment based on a virtual model, and the second maxillomandibular relationship is an maxillomandibular position relationship expected to be obtained by adjusting the first maxillomandibular relationship during the correction process.

[0117] In a possible implementation manner, the engaging structures form at least a partially continuous distribution or at least a partially discrete distribution; or form at least a partially linear distribution or at least a partially linear distribution.

[0118] In one possible implementation, the height of the occlusal structure along the sagittal direction is higher as it approaches the posterior tooth side.

[0119] In one possible implementation, the height of the occlusal structure along the sagittal direction is lower as it approaches the posterior tooth side.

[0120] In a possible implementation, the occlusal structure covers the range of teeth No. 4 to No. 7.

[0121] In a possible implementation manner, the engaging structure is a solid or hollow structure.

[0122] In one possible implementation, the surface of the occlusal structure is provided with at least partially continuously distributed microstructures, such as different types of lines, grooves, protrusions and other microstructure features, so as to increase the friction of the surface of the occlusal structure.

[0123] This embodiment also provides an invisible brace, on which a convex cavity structure or solid structure with a height, shape and surface slope relative to the dental arch is formed, the cavity structure or solid structure constitutes an occlusal structure, and when the outer surface of the brace and the outer surface of the opposing brace / tooth are in contact with each other, a second maxillomandibular relationship different from the first maxillomandibular relationship is formed;

[0124] In one possible implementation, the first maxillomandibular relationship is a specified maxillomandibular position relationship obtained by traction by the patient's muscle movement or fixed by auxiliary measures, or is an maxillomandibular position relationship obtained by manual adjustment based on a virtual model, and the second maxillomandibular relationship is an maxillomandibular position relationship expected to be obtained by adjusting the first maxillomandibular relationship during the correction process.

[0125] In a possible implementation, the occlusal structure forms at least partially continuous distribution or at least partially discrete distribution; or forms at least partially linear distribution or at least partially non-linear distribution.

[0126] In a possible implementation, when the occlusal structure is at least partially linearly distributed on the invisible orthodontic appliance, along the sagittal direction, the height is higher closer to the posterior teeth side, or along the sagittal direction, the height is lower closer to the posterior teeth side.

[0127] In a possible implementation, the occlusal structure is formed within the range of teeth No. 4 - 7 of the invisible orthodontic appliance.

[0128] In a possible implementation, a filler is provided in the cavity structure of the occlusal structure.

[0129] In a possible implementation, at least partially continuously distributed microstructures are provided on the surface of the occlusal structure.

[0130] The following further illustrates this implementation manner with several embodiments.

[0131] As Figure 2a and Figure 2b shown, Figure 2a is the first maxillomandibular relationship obtained from clinical impression taking, Figure 2b is the adjusted second maxillomandibular relationship. When designing the occlusal pad, an occlusal pad is provided on the posterior teeth of the mandible according to the first maxillomandibular relationship, so that the upper and lower jaws are in occlusion and consistent with the first maxillomandibular relationship after occlusion. However, in actual medical treatment, the doctor may hope that the more posterior teeth are depressed more, but do not want the occlusal force to be concentrated only on the terminal molars. By setting the occlusal structure 1, the height distribution along the dental arch is higher closer to the posterior teeth, and the variation is usually controlled within the range of 0.5 - 1 mm. In this way, the posterior teeth can receive a greater occlusal force, but under the action of the occlusal force, through the slight deformation of the orthodontic appliance, the premolars can also bear a certain amount of occlusal force.

[0132] As Figure 3a and Figure 3b shown, Figure 3a is the first maxillomandibular relationship obtained from clinical impression taking, Figure 3b is the adjusted second maxillomandibular relationship. The doctor may hope that the molars are subjected to less force in order to elongate the molars, and then the occlusal structure 1 can be adjusted so that the height distribution along the dental arch is lower closer to the posterior teeth, and the variation is usually controlled within the range of 0.5 - 1 mm. In this way, the force borne by the posterior teeth is smaller, and even a slight intermaxillary space may be generated.

[0133] As Figure 4 shown, by changing the thickness of the invisible orthodontic appliance 2 along the dental arch direction to change the occlusal state, the second maxillomandibular relationship is formed, and the thickened solid structure can be segmented or gradually changing.

[0134] As Figure 5 shown, by forming a cavity bulge on the invisible orthodontic appliance 2, the occlusal state is changed by the height change of the bulge structure, and the second maxillomandibular relationship is formed.

[0135] As Figure 6 shown, the occlusal structure formed on the invisible orthodontic appliance 2 is a plurality of discontinuous bulge structures.

[0136] In Figure 6 , the horizontal slopes of the occlusal structures set on the left and right jaws are different, so that the occlusal plane between the upper and lower jaws is inclined, thereby effectively correcting crossbite or generating the desired occlusal force. At this time, the upper occlusal plane in the front view rotates counterclockwise. In addition, crossbite can also be corrected or the desired occlusal force can be generated by different heights of the variable-height bodies on the left and right half jaws.

[0137] The embodiment of the present application provides a method for adjusting jaw position using an invisible orthodontic appliance, including obtaining the first maxillomandibular relationship according to the doctor's instructions; setting variable-height bodies on the orthodontic appliance; adjusting the distribution of the height, shape and surface slope of the variable-height bodies along the dental arch so that when the outer surface of the orthodontic appliance abuts against the outer surface of the opposing orthodontic appliance / tooth, a second maxillomandibular relationship different from the first maxillomandibular relationship is formed;

[0138] A possible implementation, the variable-height body can be a change in the local thickness of the orthodontic appliance shell, a convex cavity structure on the surface of the orthodontic appliance (the cavity can be filled with a solid, such as materials like photocuring resin, gel, etc.), or a solid / cavity occlusal pad fixed on the surface of the orthodontic appliance (such as materials like photocuring resin, gel, etc.);

[0139] A possible implementation, the distribution of the height, shape and surface slope of the variable-height body along the dental arch can be a discrete distribution or a continuous distribution; this distribution can be a linear distribution or a non-linear distribution;
