Description

Technical Field

[0001] This invention relates to the field of orthodontic appliance technology, and in particular to a method and apparatus for intelligently determining the diaphragm of an orthodontic appliance. Background Technology

[0002] With continuous advancements in attachments, materials, and orthodontic techniques, invisible aligners have been widely applied to correct various complex dental misalignments. Currently, when retracting teeth, invisible aligners require long-distance tooth movement, or when fine-tuning individual teeth, they require rotation or root-controlled movement. However, practical experience has revealed that the lamellae used in existing invisible aligners often do not match the orthodontic needs, easily leading to problems such as tooth tilting towards interspaces, anchorage loss, or detachment, which significantly impacts orthodontic outcomes. Therefore, providing a method to improve the accuracy of lamellae selection is crucial. Summary of the Invention

[0077] This invention discloses a method and device for intelligent determination of the diaphragm of a dental orthodontic appliance, which is beneficial to improving the reliability and accuracy of the determination of the target diaphragm, thereby improving the reliability and accuracy of the preparation of the dental orthodontic appliance, and thus improving the orthodontic effect.

[0078] Example 1

[0079] Please see Figure 1 , Figure 1 This is a flowchart illustrating a method for intelligently determining the diaphragm of a dental orthodontic appliance, as disclosed in an embodiment of the present invention. Figure 1 The described intelligent method for determining the diaphragm of orthodontic appliances can be applied to determine the diaphragm of shell-shaped pressure-film orthodontic appliances to be prepared, such as the diaphragm of invisible aligners, etc., and this embodiment of the invention is not limited thereto. Optionally, this method can be implemented by an appliance diaphragm determination system, which can be integrated into an appliance diaphragm determination device, or it can be a local server or cloud server used to process the appliance diaphragm determination process, etc., and this embodiment of the invention is not limited thereto. Figure 1 As shown, the intelligent determination method for the diaphragm of this orthodontic appliance may include the following operations:

[0080] 101. Determine the change pattern of the brace length of the orthodontic appliance to be prepared, and determine the matching target membrane set from multiple preset membrane sets based on the change pattern of the brace length.

[0081] In this embodiment of the invention, each diaphragm set includes multiple diaphragms with different elastic modulus parameters. Specifically, all diaphragm sets may include two types of diaphragm sets: one for diaphragm sets with constant brace length and another for diaphragm sets with varying brace length (e.g., decreasing brace length and increasing brace length). The elastic modulus parameter range of the diaphragms in the diaphragm set with constant brace length is earlier than that of the diaphragms in the diaphragm set with increasing brace length (e.g., the former has an elastic modulus parameter range of 1000–1300, while the latter has an elastic modulus parameter range of 1600–1750, etc.). The range of elastic modulus parameters for the diaphragms included in the diaphragm set under the length-increasing method is earlier than the range of elastic modulus parameters for the diaphragms included in the diaphragm set under the length-decreasing method (e.g., the former includes diaphragms with an elastic modulus parameter range of 1600-1750, while the latter includes diaphragms with an elastic modulus parameter range of 1750-2350, etc.). That is, the diaphragm set is arranged according to the range of elastic modulus parameters of the included diaphragms from smallest to largest. The specific parameter ranges mentioned above are not limited in this embodiment of the invention; the specific parameter ranges can be changed based on the material type, characteristics, size, etc., of the diaphragms. Furthermore, the determined diaphragm length variation method includes one of the following: diaphragm length remaining constant, diaphragm length increasing, and diaphragm length decreasing.

[0082] Furthermore, as an optional implementation, the range of elastic modulus parameters corresponding to all diaphragms in each diaphragm set is determined in the following way:

[0083] For each set of membranes to be determined, the target parameters of the materials used for all corresponding membranes are determined; the target parameters of the materials include at least one of the following: material type parameters, material cross-sectional shape parameters, material length parameters, and material cross-sectional area parameters.

[0084] Based on the target parameters of the material, determine the range of elastic modulus parameters for all diaphragms in the diaphragm set.

[0085] In this optional embodiment, the range of elastic modulus parameters that each set of diaphragms should include is determined based on the diaphragm material type, cross-sectional shape, length, and cross-sectional area, etc. The material type parameter can be understood as nickel-titanium materials or stainless steel materials with different alloy ratios, while the cross-sectional shape parameter can be understood as round / square wire nickel-titanium materials, round / square wire stainless steel materials, etc.

[0086] 102. Determine the tooth movement parameters for the different braces lengths, and based on the tooth movement parameters, identify the matching target diaphragm from all the diaphragms in the target diaphragm set.

[0087] In this embodiment of the invention, the target diaphragm is used to fabricate a dental appliance. Specifically, different changes in diaphragm length correspond to different tooth movement parameters (which can be understood as orthodontic parameters, determined based on a preset target tooth position). For example, tooth movement parameters with a constant diaphragm length include parameters for adjusting tooth rotation, parameters for tooth elongation / intrusion, and parameters for tooth root control movement; while parameters for increasing diaphragm length include parameters for mesiodistal movement, such as parameters for molar distalization and labial expansion of anterior teeth, as well as parameters for arch expansion; and parameters for decreasing diaphragm length include parameters for reducing anterior tooth torque, parameters for Spiking curve leveling, parameters for arch reduction, and parameters for closing extraction / interdental gaps. Furthermore, all diaphragms in each diaphragm set can be arranged in ascending order of their corresponding elastic modulus parameters.

[0088] As can be seen, implementing the embodiments of the present invention can intelligently determine the target membrane from the membrane set based on the change mode of the braces length and the tooth movement parameters under the change mode of the braces length, and use the target membrane to prepare the orthodontic appliance. This is beneficial to improving the reliability and accuracy of the determination of the target membrane, which in turn is beneficial to improving the reliability and accuracy of the preparation of the orthodontic appliance, thereby improving the orthodontic effect on the teeth.

[0089] Example 2

[0090] Please see Figure 2 , Figure 2 This is a flowchart illustrating a method for intelligently determining the diaphragm of a dental orthodontic appliance, as disclosed in an embodiment of the present invention. Figure 2 The described intelligent method for determining the diaphragm of orthodontic appliances can be applied to determine the diaphragm of shell-shaped pressure-film orthodontic appliances to be prepared, such as the diaphragm of invisible aligners, etc., and this embodiment of the invention is not limited thereto. Optionally, this method can be implemented by an appliance diaphragm determination system, which can be integrated into an appliance diaphragm determination device, or it can be a local server or cloud server used to process the appliance diaphragm determination process, etc., and this embodiment of the invention is not limited thereto. Figure 2 As shown, the intelligent determination method for the diaphragm of this orthodontic appliance may include the following operations:

[0091] 201. Determine the method of changing the length of the braces of the orthodontic appliance to be prepared.

[0092] 202. When the braces length change method includes the braces length not changing method, the first diaphragm set is determined from the preset multiple diaphragm sets as the matching target diaphragm set.

[0093] In an embodiment of the present invention, the first set of diaphragms includes at least a diaphragm capable of adjusting tooth rotation release, a diaphragm capable of elongating / indenting individual teeth, and a diaphragm capable of controlling tooth root movement.

[0094] 203. When the braces length change method includes the braces length increase change method, a second diaphragm set is determined from the preset multiple diaphragm sets as the matching target diaphragm set.

[0095] In an embodiment of the present invention, the second set of membranes includes at least a membrane capable of pushing molars distally, a membrane capable of labially expanding anterior teeth, and a membrane capable of expanding the arch of teeth.

[0096] 204. When the braces length change method includes the braces length reduction change method, a third diaphragm set is determined from the preset multiple diaphragm sets as the matching target diaphragm set.

[0097] In this embodiment of the invention, specifically, the elastic modulus parameters of all diaphragms in the first diaphragm set are smaller than those of all diaphragms in the second diaphragm set, and the elastic modulus parameters of all diaphragms in the second diaphragm set are smaller than those of all diaphragms in the third diaphragm set. The third diaphragm set may include diaphragms capable of reducing anterior tooth torque and leveling the Spitz curve, and may also include diaphragms capable of retracting the dental arch, etc.

[0098] 205. Determine the tooth movement parameters for the different braces lengths, and based on the tooth movement parameters, identify the matching target diaphragm from all the diaphragms in the target diaphragm set.

[0099] In this embodiment of the invention, for other descriptions of steps 201 and 205, please refer to the detailed description of steps 101-102 in Embodiment 1. This embodiment of the invention will not repeat them.

[0100] As can be seen, by implementing the embodiments of the present invention, a target diaphragm set can be determined from a set of preset diaphragms according to the specific braces change mode. This allows the diaphragm set to flexibly match the required braces change mode, thereby improving the reliability and accuracy of determining the target diaphragm set. This, in turn, improves the reliability and accuracy of subsequent determination of the target diaphragm under tooth movement parameters, so as to meet the preparation requirements of different orthodontic appliances.

[0101] In an optional embodiment, step 205 above, determining the matching target membrane from all membranes included in the target membrane set based on tooth movement parameters, includes:

[0102] When the tooth movement parameters include tooth torsion release adjustment parameters for a constant brace length, the first diaphragm is determined from all diaphragms in the first diaphragm set based on the tooth torsion release adjustment parameters, and is used as the matching target diaphragm.

[0103] When the tooth movement parameters include tooth elongation / indentation movement parameters for a constant brace length, a second diaphragm is determined from all diaphragms in the first diaphragm set based on the tooth elongation / indentation movement parameters, as the matching target diaphragm.

[0104] When the tooth movement parameters include tooth root control movement parameters for a constant brace length, a third membrane is determined from all membranes in the first membrane set as the matching target membrane based on the tooth root control movement parameters.

[0105] In this optional embodiment, the elastic modulus parameter of the first diaphragm is smaller than that of the second diaphragm, and the elastic modulus parameter of the second diaphragm is smaller than that of the third diaphragm. Optionally, the tooth rotation release adjustment parameters may include tooth rotation release adjustment direction parameters and / or tooth rotation release adjustment angle parameters; while the tooth elongation / intrusion movement parameters may include tooth intrusion height parameters, tooth elongation height parameters, tooth elongation direction parameters, and tooth intrusion direction parameters, etc.; and the tooth root control movement parameters may include tooth root control movement direction parameters and / or tooth root control movement distance parameters.

[0106] For example, when adjusting to remove tooth rotation, a first membrane is used to prepare the orthodontic appliance; when moving individual teeth, such as indentation or elongation, a second membrane is used; and when moving teeth by controlling the root, a third membrane is used.

[0107] Furthermore, the first, second, and third diaphragms can each contain multiple sub-diaphragms arranged in ascending order of elastic modulus. The specific sub-diaphragms to be used can be determined based on the magnitude of the tooth rotation release adjustment parameters, tooth elongation / indentation movement parameters, or tooth root control movement parameters.

[0108] As can be seen, this optional embodiment can determine the target membrane from the first membrane set based on specific tooth movement parameters under the condition of constant braces length, such as tooth rotation release adjustment parameters, tooth elongation / indentation movement parameters, and tooth root control movement parameters. This helps to improve the reliability and accuracy of determining the target membrane under the condition of constant braces length, and in turn, helps to improve the reliability and accuracy of the preparation of orthodontic appliances, thereby helping to meet the required orthodontic needs and improve the orthodontic effect.

[0109] In another optional embodiment, step 205 above, determining the matching target membrane from all membranes included in the target membrane set based on tooth movement parameters, includes:

[0110] When the tooth movement parameters include mesiodistal movement parameters for the change in braces length, a fourth diaphragm is determined from all diaphragms in the second diaphragm set based on the mesiodistal movement parameters, as the matching target diaphragm.

[0111] When the tooth movement parameters include arch expansion parameters for different braces lengths, the fifth diaphragm is determined from all diaphragms in the second diaphragm set as the matching target diaphragm, based on the arch expansion parameters.

[0112] In this optional embodiment, the elastic modulus parameter of the fourth diaphragm is smaller than that of the fifth diaphragm. Optionally, the mesiodistal movement parameters may include parameters for the distal direction of the molar pushing teeth, the distal distance of the molar pushing teeth, the labial expansion angle of the anterior teeth, the labial expansion distance of the anterior teeth, etc.; while the arch expansion parameters may include parameters for the direction of arch expansion, the distance of arch expansion, and the number of teeth to be expanded, etc.

[0113] For example, when pushing molars distally or expanding anterior teeth labially, a fourth membrane is used to prepare the orthodontic appliance; when expanding the arch of the teeth, a fifth membrane is used to prepare the orthodontic appliance.

[0114] Furthermore, the fourth and fifth diaphragms can each contain multiple sub-diaphragms with elastic modulus parameters arranged from smallest to largest. The specific sub-diaphragms to be used can be determined based on the magnitude of the mesiodistal movement parameters or the dental arch expansion parameters.

[0115] As can be seen, this optional embodiment can determine the target membrane from the second membrane set based on specific tooth movement parameters under the braces length increase method, such as mesiodistal movement parameters and arch expansion parameters. This helps to improve the reliability and accuracy of the target membrane determination under the braces length increase method, and in turn, helps to further improve the reliability and accuracy of the preparation of orthodontic appliances, thereby helping to comprehensively improve the orthodontic effect.

[0116] In yet another optional embodiment, step 205 above, determining the matching target membrane from all membranes included in the target membrane set based on tooth movement parameters, includes:

[0117] When the tooth movement parameters include the anterior tooth torque reduction parameters and the Spi curve leveling parameters under the change of brace length reduction, the anterior tooth torque reduction threshold range of the anterior tooth torque reduction parameters is determined according to the anterior tooth torque reduction parameters, and the Spi curve leveling threshold range of the Spi curve leveling parameters is determined according to the Spi curve leveling parameters.

[0118] Based on the anterior torque reduction parameter and the Spi curve leveling parameter, a matching target diaphragm is determined from all diaphragms included in the third diaphragm set.

[0119] In this optional embodiment, the matching target diaphragm can be further determined from all the diaphragms included in the third diaphragm set based on the anterior torque reduction threshold range where the anterior torque reduction parameter is located and the Spi curve leveling threshold range where the Spi curve leveling parameter is located, and in combination with the arch retraction movement parameter under the braces length reduction change mode.

In this way, the reliability and accuracy of the determination of the target diaphragm under the braces length reduction method can be improved, so as to meet the preparation requirements of orthodontic appliances for different orthodontic needs under the braces length reduction method.

[0121] In another optional embodiment, the step of determining the matching target diaphragm from all diaphragms included in the third diaphragm set based on the anterior torque reduction threshold range where the anterior torque reduction parameter is located and the Spiro curve leveling threshold range where the Spiro curve leveling parameter is located includes:

[0122] When the anterior tooth torque reduction parameter is located within the first torque reduction threshold range and the Spi curve leveling parameter is located within the first leveling threshold range, the sixth diaphragm is determined from all the diaphragms included in the third diaphragm set based on the anterior tooth torque reduction parameter and the Spi curve leveling parameter, and is used as the matching target diaphragm.

[0123] When the anterior tooth torque reduction parameter is located within the anterior tooth torque reduction threshold range and the Spi curve leveling parameter is located within the Spi curve leveling threshold range, the seventh diaphragm is determined from all the diaphragms included in the third diaphragm set based on the anterior tooth torque reduction parameter and the Spi curve leveling parameter, and is used as the matching target diaphragm.

[0126] In this optional embodiment, the second torque reduction threshold range is before the first torque reduction threshold range and after the third torque reduction threshold range, and the third torque reduction threshold range is after the fourth torque reduction threshold range; and the second leveling threshold range is after the first leveling threshold range and before the third leveling threshold range, and the third leveling threshold range is before the fourth leveling threshold range; and the elastic modulus parameter of the seventh diaphragm is greater than the elastic modulus parameter of the sixth diaphragm and less than the elastic modulus parameter of the eighth diaphragm, and the elastic modulus parameter of the eighth diaphragm is less than the elastic modulus parameter of the ninth diaphragm.

[0127] Optionally, the anterior torque reduction parameters include the anterior torque reduction angle parameter and / or the anterior torque reduction direction parameter; while the Spi curve leveling parameters include the Spi curve leveling height parameter.

[0128] For example, if the anterior torque reduction angle parameter is 20 degrees or more and the Spi curve flattening is 0.3 mm or less, then the sixth diaphragm is used to prepare the orthodontic appliance; if the anterior torque reduction angle parameter is 15 to 20 degrees and the Spi curve flattening is 0.3 mm to 0.6 mm, then the seventh diaphragm is used to prepare the orthodontic appliance, and so on.

[0129] As can be seen, this optional embodiment can determine the target membrane from the third membrane set based on specific tooth movement parameters under the braces length reduction method, such as anterior tooth torque reduction parameters and Spi curve leveling parameters. This helps to improve the reliability and accuracy of determining the target membrane under the braces length reduction method, which in turn helps to further improve the reliability and accuracy of the preparation of orthodontic appliances, thereby helping to comprehensively improve the orthodontic effect.
