Description
Technical Field
The invention belongs to the field of medical appliances, relates to a tooth reshaping device, and particularly relates to a tooth straightening auxiliary device for anterior teeth and a tooth straightening device.
Background
The transparent appliance is a series of transparent appliances manufactured by the steps of scanning the mouth, taking a model, scanning a plaster model or an impression to obtain a digital model of dentition of a patient, dividing the digital dentition model into single movable digital dentition units, rearranging the dentition units to obtain needed corrected dentition, obtaining a series of intermediate digital dentition models by a step-by-step method, printing the intermediate models in a 3D way, and manufacturing a series of transparent appliances by using a thermoplastic molding film-pressing material. The patient corrects the dentition misalignment by wearing these series of transparent appliances.
Transparent appliances present many uncertainties and inaccessible ways of movement for tooth movement. For the transparent appliance, the effect of aligning the dentition is obvious when the crowded cases are corrected, but the whole treatment effect is not as good as that of the fixed appliance, and the occlusion contact is mainly realized. The transparent appliance design is based on a digitized model, and the upper and lower jaw bite positions of the digitized model are based on the initial neutral position of the patient. When the upper dentition and the lower dentition are arranged, the occlusion of the upper dentition, the lower dentition and the dentition can be changed, but the occlusion relation after the tooth arrangement is designed is artificially determined after digital teeth are moved, and the actual occlusion position of a patient cannot be expressed. Meanwhile, the digital model based on which the existing transparent appliance is designed lacks the relation of relative movement positions of the lower jaw when the mouth is opened or closed. Therefore, the transparent appliance is often not good in the occlusion relationship of the posterior teeth after being corrected, and even opens and closes. The transparent appliance corrects the irregular dentition, the upper part and the lower part of the appliance are separated, and the upper dentition and the lower dentition are actually in occlusion relation. The position of the anterior teeth often in turn affects the initial bite position of the patient. In the process of correction, the teeth are often difficult to bite into a stable position along with the change of the positions of the teeth, and finally, the occlusion effect is poor.

Example 1 Upper anterior labial inclination coverage was greater
In the clinical situation, the patient has a large lip inclination coverage of the upper anterior teeth, and the upper and lower anterior teeth with the transparent appliance are schematically shown in fig. 3 (a). When the upper and lower anterior teeth are engaged, the lower anterior teeth are likely to be engaged posteriorly on the palatal side of the upper anterior teeth to form a deep occlusal deep coverage, as shown in fig. 3 (b). In the case of such a large upper anterior labial capsizing, the maxillary anterior occlusal locator 101 and the mandibular anterior occlusal locator 201 are designed as shown in fig. 4: designing a maxillary anterior occlusion positioner 101 at the maxillary hyoplasty occlusion site (upper anterior palatal side, middle of crown 1/3) with the lower incisor; at the cut end of the lower incisor 20, a mandibular anterior occlusal locator 201 is designed along the lower anterior occlusal vertical line 2.
The patient wears the orthodontic device of the present invention, i.e., the above-described transparent appliance is attached with an orthodontic auxiliary device (bite locator), as shown in fig. 3 (c), while the anterior mandibular bite locator 201 is positioned on the labial side of the lower incisors 20. The upper and lower teeth are engaged by the occlusion locator in a stable and comfortable position as shown in fig. 3 (d). After the patient wears the orthodontic device of the present invention for one orthodontic period, the orthodontic device is removed and a good occlusal relationship is obtained after the upper and lower teeth are straightened, as shown in (e) of fig. 3.
EXAMPLE 2 little overlying of the Upper anterior palate
In the clinical situation, the palate of the upper anterior teeth of the patient is less prone to toppling, and as shown in fig. 5 (a), the upper and lower anterior teeth of the patient are schematically shown with the transparent appliance. When the upper and lower anterior teeth are engaged, the lower anterior teeth are likely to be engaged posteriorly on the palatal side of the upper anterior teeth to form a deep bite, as shown in fig. 5 (b). For the case that the upper anterior palate is less prone to toppling, the designs of the maxillary anterior bite positioner 101 and the mandibular anterior bite positioner 201 are as shown in fig. 6: designing a maxillary anterior occlusion positioner 101 at the maxillary hyoplasty occlusion site (upper anterior palatal side, position of incisor 1/3 of crown); at the cut end of the lower incisor 20, a mandibular anterior occlusal locator 201 is designed along the lower anterior occlusal vertical line 2.
The patient wears the orthodontic device of the present invention, i.e., the above-described transparent appliance is attached with an orthodontic auxiliary device (bite locator), as shown in fig. 5 (c), while the anterior mandibular bite locator 201 is positioned at the incisor end of the lower incisors 20. The upper and lower teeth are engaged by the engaging positioner (101, 201) at a stable and comfortable position as shown in fig. 5 (d). After the patient wears the orthodontic device of the present invention for one orthodontic period, the orthodontic device is removed and a good occlusal relationship is obtained after the upper and lower teeth are straightened, as shown in (e) of fig. 5.
In conclusion, the occlusion positioner is arranged on the conventional appliance, so that when the upper and lower teeth of a patient are occluded, the occlusion positioner is always occluded at a stable and comfortable position through the upper and lower anterior mandibular teeth, the occlusion relationship after treatment is improved, and the patient obtains a more stable occlusion function. The auxiliary device for orthodontics of the invention can avoid the defect that the occlusal problem needs to be corrected by a method of restarting, remanufacturing a transparent appliance or clinically using a fixed appliance in clinical application.
