Description

Orthodontic system for oral treatment

The embodiment of the invention belongs to the technical field of orthodontics, and particularly relates to an orthodontic system for treating the oral cavity.

Regarding early malocclusion during the growth and development stage of children, studies have shown that muscles have a critical impact on the stability of orthodontic treatment during the developmental stage, and in some cases muscle problems are the cause of oral problems, and muscles are ignored. Problems may make treatment less effective or relapse after treatment.

Orofacial myofunctional therapy (OMT) is a multidisciplinary comprehensive treatment method for the assessment, diagnosis, prevention and treatment of patients in the growth and development stage who have abnormalities in orofacial muscles and their functions. Its mechanism is to promote the normal development of craniofacial structures and the coordination and stability of the functions of the orofacial system through re-education of the nerves and muscles of the orofacial area. It is a treatment method that focuses on the cause of the disease.

In the existing technology, silicone appliances made of medical-grade silicone materials are mainly used to treat early-stage malocclusion. This type of appliance is an early appliance that uses growth and development to correct malocclusion. It has a beautiful appearance and is comfortable to wear. The characteristics of the device prevent children from refusing to wear the appliance due to the pain, causing poor physical and mental development and other problems. As a result, more and more people are using silicone appliances as a tool for early malocclusion correction.

In the current dental treatment for children, the doctor will match a silicone appliance according to the patient's current dental arch size for treatment. Existing products usually provide doctors with several sizes to choose from. Therefore, the size of the silicone appliance is relatively fixed and cannot be accurately customized according to the patient's oral cavity and dentition. Similarly, it is also impossible to achieve the correct treatment for the wrong patient. When the jaw deformity is deep overjet or crossbite, it is often the case that the silicone appliance exerts excessive corrective force on the teeth, causing the teeth in the front teeth to have undesired labial and lingual lateral tilt or the mandibular rotation or reverse rotation. This leads to treatment failure.

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, each implementation mode of the present invention will be described in detail below with reference to the accompanying drawings. However, those with ordinary knowledge in the art can understand that in each implementation manner of the present invention, many technical details are provided to enable readers to better understand the present invention. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solution claimed in this creation can also be realized. The division of the following embodiments is for the convenience of description and should not constitute any limitation on the specific implementation of the present invention. The various embodiments can be combined with each other and referenced with each other on the premise that there is no contradiction.

The "posterior tooth area" mentioned in various embodiments of this creation is defined according to the classification of teeth on pages 36 to 38 of the second edition of "Introduction to Oral Medicine" published by Peking University Medical Press, including premolars and molars. , teeth numbered 4 to 8 according to the FDI (Fédération Dentaire Internationale, International Dental Federation) notation, and teeth 1 to 3 according to the FDI notation in the anterior region. The teeth in the anterior region include central incisors, lateral incisors, and canines. In addition, for the description of teeth in the deciduous stage, the "posterior tooth area" is defined according to the classification of deciduous teeth on pages 40~41 of the second edition of "Introduction to Oral Medicine" published by Peking University Medical Press, including deciduous incision. There are three categories of teeth, deciduous canines and deciduous molars. Among them, deciduous incisors include deciduous central teeth and deciduous lateral incisors, and deciduous molars include first deciduous molars and second deciduous molars.

Studies have shown that mandibular protrusion promotes the growth rate and amount of condylar cartilage cells, enhances the functional activity of the lateral pterygoid muscles, and increases the length of the mandible. At the same time, studies have found that the stress value and displacement of the condylar cartilage surface are obviously related to the distance between mandibular protrusion and mouth opening, and are positively correlated. Therefore, it is suggested that the distance of mandibular protrusion should not be too large to prevent the stress distribution on the condylar surface from being too large and exceeding the body. pathological damage to the adaptive ability. In the past, silicone braces did not take this problem into consideration, and they always guided the mandible to the opposite edge of the front teeth at one time. The orthodontic system for oral treatment in this creation moves forward step by step for patients with deep coverage who have severe sagittal imbalance. The step-by-step forward movement is more conducive to the reconstruction of the condylar tissue, making it easier for patients to adapt.

Therefore, in order to solve the problem that when the silicone appliance in the prior art is used to treat early malocclusion cases, when the silicone appliance exerts an excessive corrective force on the teeth, the teeth in the anterior teeth area may experience undesirable labial and lingual lateral tilt or mandibular rotation or rotation. The problem of reverse rotation, and the effective reconstruction of the condylar tissue. This creation proposes an orthodontic system for oral treatment, as shown in Figure 1. In one embodiment, an orthodontic system for oral treatment is provided, including a series of appliances, and the series of appliances are designed to gradually realize the treatment plan. The series of appliances includes at least a first appliance 1 and a second appliance 2 . The first appliance 1 and the second appliance 2 may be made of polymeric materials, and the polymeric materials may be siloxane polymers or silane polymers. In one form of this invention, the silicon-containing polymer is silicone rubber, for example, medical silicone that has been recognized by the dental field in my country. The silicone material is particularly soft and comfortable against the consumer's gums and other oral tissues. It also has a certain ability to elastically deform.

Continuing to refer to Figures 2 and 3, the first appliance 1 includes a first bearing portion 11 that is in contact with at least part of the teeth. The first bearing portion 11 is arranged parallel to the occlusal surface or the horizontal plane and is in contact with the jaw surface of some of the teeth. The lingual edge of the first bearing part 11 extends toward the gums to form the first inner wall 12 located on the lingual side of the dental arch. Specifically, it may extend 1 mm to 3 mm in the maxillary and mandibular directions respectively to cover the lingual surfaces of the maxillary teeth and mandibular teeth. Part of the gum area. The labial and buccal edges of the first bearing part 11 extend toward the gum direction to form the first lateral wall 13. Similarly, the second lateral wall 23 may extend 1 mm to 9 mm in the maxillary and mandibular directions respectively to cover the labial teeth of the maxillary teeth and the mandibular teeth. The side and part of the gum area, and the first lateral wall 13 can block the contact between the labial and buccal muscles and the dentition, thereby eliminating the influence of the muscles on the tooth correction during the correction process. The first outer wall 13, the first bearing portion 11 and the first inner wall 12 surround a first upper groove 14 defining the upper dental arch and a first lower groove 15 defining the lower dental arch; the front teeth of the first upper groove 14 The area has a first distance L1 in the sagittal direction from the anterior area of the first inferior groove 15 for the first stage of the treatment plan.

The second appliance 2 in the orthodontic system has a similar shape to the first appliance 1. Specifically, the second appliance 2 includes a second bearing portion 21 that is in contact with at least part of the teeth. The second bearing portion 21 is parallel to the occlusal plane or the horizontal plane. Set up and in contact with the maxillofacial surface of part of the teeth. The lingual edge of the second bearing part 21 extends toward the gums to form a second inner wall 22 located on the lingual side of the dental arch. Specifically, it may extend 1 mm to 3 mm in the maxillary and mandibular directions respectively to cover the lingual surfaces of the maxillary teeth and mandibular teeth. Part of the gum area. The labial and buccal edge of the second bearing part 21 extends toward the gum direction to form a second lateral wall 23. Similarly, the second lateral wall 23 may extend 1 mm to 9 mm in the upper and lower jaw directions respectively to cover the upper and lower jaw teeth. The side and part of the gum area, and the second outer wall 23 can block the contact between the labial and buccal muscles and the dentition, thereby eliminating the influence of the muscles on the tooth correction during the correction process. The second outer wall 23, the second bearing portion 21 and the second inner wall 22 surround a second upper groove 24 defining the upper dental arch and a second lower groove 25 defining the lower dental arch; the anterior region of the second upper groove 24 There is a second distance L2 in the sagittal direction from the anterior region of the second inferior groove 25 for the second stage of the treatment plan. The first distance L1 and the second distance L2 are different.

In the book "Orthodontic Clinical Treatment Based on Respiratory and Perioral Muscle Function" written by Etsuko Kondo and translated by Bai Yuxing, Yang Li, and Zhao Hong, it is mentioned that "any orthodontic appliance, no matter how effective it is in aligning teeth, can The stability of the final position of the teeth still depends on the mechanical balance between multiple functions such as the oral and jaw system and the respiratory system." Therefore, the orthodontic system in this creation uses appliances to treat dentition problems or malocclusion. When problems arise, the condition of the perioral muscles is also used as one of the reference factors, and the lateral wall structure of the appliance is used to block the contact between the labial and buccal muscles and the dentition, thereby eliminating the influence of the perioral muscles on the correction and making the correction more accurate and reliable. .

In some embodiments, as shown in FIG. 4 , vertically upward, the height H1 of the first lateral wall 13 / the second lateral wall 23 in the anterior tooth area is between 19 mm and 26 mm, and the height H2 in the posterior tooth area is between 8 mm and 13 mm. time to meet the adaptability of the appliance to the patient's oral conditions during the wearing process, such as to meet the matching relationship for dental arches of different sizes. And for the braces used at different stages, the size can also be changed according to the needs of correction to provide the accuracy of correction.

In some embodiments, the correction plan can be divided into multiple correction stages to gradually adjust the sagittal relationship between the maxilla and the mandible. For example, when the second stage corresponding to the second appliance 2 is a subsequent stage to the first stage corresponding to the first appliance 1, the second distance L2 is smaller than the first distance L1, and the second distance L2 is closer to the first distance L1. Treatment goals.

In some embodiments, as shown in FIG. 3 , the first distance L1 is between 3 mm and 5 mm; the second distance L2 is between 1 mm and 3 mm. For example, an orthodontic system for treating the oral cavity includes three appliances, and the sagittal distances between the anterior teeth area of the upper groove and the anterior teeth area of the lower groove of the three appliances are 1 mm, 3 mm, and 5 mm respectively. The first appliance 1 and the second appliance 2 are any two of the three appliances.

In other embodiments, when the first stage and the second stage are adjacent stages of the treatment plan, the difference between the first distance and the second distance is between 1 mm and 5 mm. Preferably, the difference between the first distance and the second distance is 2 mm or 3 mm. Furthermore, from the first stage to the second stage, it can be understood that the maxillary dentition or the mandibular dentition moves alone, or the maxillary dentition and the mandibular dentition move together.

In some embodiments, an orthodontic system for treating the oral cavity may be used to treat cases of deep overbite or underbite. When the orthodontic system was used to treat deep coverage cases, as shown in Figure 2, the relative arrangement of the first upper groove 14 and the first lower groove 15 in the sagittal direction and the relative arrangement of the second upper groove 24 and the second lower groove 25 in the sagittal direction. The relative position relationship in the sagittal upward direction is consistent. Specifically, the anterior tooth area of the first upper groove 14 is closer to the labial side than the anterior tooth area of the first lower groove 15, and the anterior tooth area of the second upper groove 24 is closer to the labial side than the second lower groove. The front teeth area of 25 is closer to the labial side, that is, the front teeth area of the first lower groove 15 is closer to the tongue than the front teeth area of the first upper groove 14, and the front teeth area of the second lower groove 25 is closer to the tongue than the second upper groove 25. The anterior teeth area of the groove 24 is closer to the tongue body. Through the first appliance 1 and the second appliance 2 in the orthodontic system, the patient can gradually reduce the amount of coverage to achieve a correct overbite coverage relationship.

When the orthodontic system was used to treat crossbite cases, as shown in Figure 5, the relative arrangement relationship between the first upper groove 14 and the first lower groove 15 in the sagittal direction and the relative arrangement relationship between the second upper groove 24 and the second lower groove 25 are shown in Figure 5. The relative positional relationship in the sagittal direction is consistent. For example, the anterior tooth area of the first lower groove 15 is closer to the labial side than the anterior tooth area of the first upper groove 14, and the anterior tooth area of the second lower groove 25 is closer to the labial side than the second upper groove. The anterior tooth area of 24 is closer to the labial side, that is, the anterior tooth area of the first upper groove 14 is closer to the tongue than the anterior tooth area of the first lower groove 15, and the anterior tooth area of the second upper groove 24 is closer to the tongue than the second lower groove. The anterior region of groove 25 is closer to the tongue body. Or as shown in FIG. 6 , the relative arrangement relationship between the first upper groove 14 and the first lower groove 15 in the sagittal direction is inconsistent with the relative positional relationship between the second upper groove 24 and the second lower groove 25 in the sagittal direction. The patient can achieve a correct coverage relationship through the first appliance 1 and the second appliance 2. For example, the anterior region of the first lower groove 15 is closer to the labial side than the anterior region of the first upper groove 14, that is, the anterior region of the first lower groove 15 is closer to the labial side. The lower groove 15 is in front of the first upper groove 14; the anterior tooth area of the second upper groove 24 is closer to the labial side than the anterior tooth area of the second lower groove 25, that is, the second upper groove 24 is in the second lower groove 25 In the front, in this case of treating crossbite patients, the second appliance 2 can be the last appliance in the orthodontic system to treat the oral cavity. The target position of the second stage is also the final target position of the final correction. The second appliance Aligner 2 provides the correct overbite coverage relationship.

In some embodiments, as shown in FIGS. 7 and 8 , the first appliance 1 or the second appliance 2 is also provided with a torque ridge 3 that prevents labial and lingual lateral rotation of some teeth in the anterior region. For example, the inner surface of the first inner side wall 12 and/or the inner surface of the first outer side wall 13 is provided with a torque ridge 3 . The inner surface of the second inner side wall 22 and/or the inner surface of the second outer side wall 23 is provided with a torque ridge 3 . The torque ridge 3 is formed by the inner surface protruding toward the tooth, and the protrusion height of the torque ridge 3 in the vertical direction is less than or equal to 0.5 mm.

In some embodiments, as shown with reference to Figures 7 and 8, the torque ridge 3 is disposed adjacent the incisal ends of the teeth in the anterior region. When the surface on one side of the groove pushes the tooth to move in the sagittal direction, the surface on the other side of the groove, adjacent to the incisal position of the tooth, bulges toward the tooth to form a torque ridge 3 to prevent the tooth from undesired labial and lingual movement during movement. tilt towards.

For example, in a case where the first appliance 1 is used to correct a deep overbite, as shown in FIGS. 9 and 10 , the anterior region of the first lower groove 15 of the first appliance 1 is larger than the anterior region of the first upper groove 14 . The dental area is closer to the tongue body. The inner surface of the first lateral wall 13 of the first upper groove 14 exerts a lingual force F1 on the teeth 100 in the maxillary anterior region. The teeth are prone to lingual rotation at the incisal position. Therefore, on the first medial wall 12 The inner surface of the first upper groove 14 is provided with a torque ridge 3; the inner surface of the first inner wall 12 of the first lower groove 15 will exert a labial lateral movement force F2 on the teeth 200 in the mandibular anterior region, Teeth tend to rotate labially at the incisal position. Therefore, a torque ridge 3 is provided on the inner surface of the first outer wall 13 located in the first lower groove 15 .

For another example, in a case where the first appliance 1 is used to correct an crossbite, the patient's mandibular front teeth are located in front of the maxillary front teeth, which is what we often call the sky. The mandibular front teeth need to be retracted and/or the maxillary front teeth need to be retracted. The anterior teeth are pulled. Therefore, in response to the above situation, as shown in FIGS. 11 and 12 , the anterior tooth area of the first upper groove 14 of the first appliance 1 is closer to the tongue than the anterior tooth area of the first lower groove 15 . The inner surface of the first medial wall 12 of the first upper groove 14 exerts a labial lateral movement force F3 on the teeth 100 in the maxillary anterior region. The teeth tend to rotate labially at the incisal position. Therefore, on the first lateral wall 13 The inner surface of the first upper groove 14 is provided with a torque ridge 3; the inner surface of the first outer wall 13 of the first lower groove 15 will exert a lingual lateral movement force F4 on the teeth 200 in the mandibular anterior region, Teeth are prone to lingual rotation at the incisal position. Therefore, a torque ridge 3 is provided on the inner surface of the first inner wall 12 located in the first lower groove 15 .

In some embodiments, as shown in FIGS. 7 and 8 , the torque ridges 3 may be connected or discontinuously arranged in the anterior tooth region. When the torque ridges 3 are connected and arranged in the anterior tooth area, the torque ridges 3 continuously cover at least 4 teeth along the direction of the dental arch curve. Alternatively, the torque ridges 3 cover at most 3 teeth in a spaced manner and at least 2 teeth. Or, for the position of a tooth prone to labial and lingual tilt, a torque ridge 3 is provided along the mesio-distal direction of the tooth.

In some embodiments, the vertically upward height of the first bearing portion 11 in the anterior teeth region is consistent with the vertically upward height of the second bearing portion 21 in the anterior teeth region. The vertical height of the first load-bearing part 11 and the second load-bearing part 21 in the anterior teeth area is the target overbite relationship in the orthodontic plan. For each pair of appliances in the orthodontic system, the vertical height of the load-bearing part in the anterior teeth area is All are kept consistent, allowing the teeth in the maxillary and/or mandibular anterior area to be gradually depressed to achieve the target overbite relationship.

In some embodiments, with reference to FIG. 13 , under the arrangement of the teeth in the current orthodontic stage, the height of the bearing part of the appliance in the posterior region compensates for the gap between the surface of the posterior region of the bearing part and the teeth at the corresponding position. X. Moreover, as the orthodontic treatment progresses, the vertical height of the posterior teeth area of the bearing part of the appliance gradually decreases, gradually flattening the Spee curve (mandibular longitudinal curve), thereby preventing premature contact of the anterior teeth and causing the opening of the posterior teeth. Jaw problems, so that when the front teeth are retracted during the correction process, the lower front teeth will not cause the lower front teeth to hit the rear front teeth in advance. This allows the occlusal relationship to be gradually adjusted during the correction process.

For example, as shown in FIGS. 14 and 15 , in the first stage of the treatment plan, the height of the posterior region of the first bearing part 11 in the vertical upward direction compensates the surface of the posterior region of the first bearing part 11 and the height at the corresponding position. Space between teeth X. In the second stage of the treatment plan, the vertically upward height of the posterior region of the second bearing portion 21 compensates for the gap X between the surface of the posterior region of the second bearing portion 21 and the teeth at the corresponding position. The height X1 of the first bearing part 11 in the posterior tooth area is greater than the height X1 of the second bearing part 21 in the rear tooth area. The height X1 of the first bearing part 11 in the posterior tooth area is between 15 mm and 2 mm; the height X2 of the second bearing part 21 in the rear tooth area is between 6 mm and 2 mm.

In some embodiments, as shown in Figures 16 to 19, the surface of the bearing part of the appliance is provided with a jaw pad 4 that adjusts the vertical occlusion relationship of the upper and lower jaws and is detachably connected to the bearing part. The jaw pad 4 is detachably connected to limit at least two The degree of freedom of snapping ensures that the jaw pad 4 can remain stable on the bearing part after installation and will not move or fall during use.

In addition, the height of the jaw pad 4 compensates for the gap between the surface of the posterior teeth of the bearing part and the teeth at the corresponding positions. The jaw pad 4 is arranged along the dental arch curve on the bearing part. The jaw pad 4 can cover one or more of the posterior teeth. Multiple teeth. The gap between the back teeth surface of the height compensation bearing part of the jaw pad 4 and the teeth at the corresponding positions mainly includes the following situations: In the first case, the jaw pad 4 only contacts the occlusal surface of the corresponding teeth without exerting clinical influence. Orthodontic force, in this case, the designed height of the jaw pad 4 at this tooth position is equal to the gap formed by the current arrangement of teeth in the posterior tooth area. In the second case, the jaw pad 4 exerts clinical correction/intrusion force on the corresponding teeth. For example, in this case, the designed height of the jaw pad 4 at this tooth position is greater than the gap formed by the current arrangement of teeth in the posterior area. Therefore, the jaw pad 4 can exert a corrective force toward the gums after the jaw pad 4 contacts the teeth.

In some embodiments, the jaw pads 4 are continuously arranged along the direction of the dental arch curve. The advantage of the continuous arrangement of the jaw pads 4 is that the Spee curve can be gradually leveled by adjusting the height of the jaw pads 4 in different orthodontic processes.

In some embodiments, when the jaw pad 4 is continuously arranged along the dental arch curve in the posterior region, the height of the jaw pad 4 may gradually decrease from an end adjacent to the anterior region to an end away from the anterior region. Alternatively, the height of the jaw pad 4 may gradually increase from an end adjacent to the front teeth area to an end far away from the front teeth area. The height of the jaw pad 4 is specifically the height of the jaw pad 4 in the vertical direction, and the height of the jaw pad 4 can be set between 0 and 15 mm.

In other embodiments, the jaw pads 4 are spaced apart along the direction of the dental arch curve. The advantage of continuously setting the jaw pads 4 is that when individual teeth need pressure, the jaw pads 4 are installed at the corresponding position of the tooth on the bearing part; or, when individual teeth need to be elongated, the jaw pads 4 are installed at the corresponding position of the adjacent tooth on the bearing part. The jaw pad 4 allows the teeth that need to be elongated to have elongation space. The spacing of the jaw pads 4 can achieve precise correction of individual teeth, and the required height of the jaw pads 4 can be flexibly replaced for different orthodontic stages.
