Description
Technical Field
The utility model belongs to the technical field of orthodontic device, especially, relate to a removable vertical nearly well slope second molar orthodontic device.
Background
In orthodontic clinical work, the most common is to move the teeth of a patient so as to achieve a good occlusion relationship. When the molar teeth are inclined in the mesial direction, the molar teeth cannot be normally occluded with the jaw teeth. If the angle of inclination of the molar teeth is small, oral problems such as local food impaction may occur. If the inclination angle of the molars is larger, the inclined molars are often inhibited from growing, namely, the molars are failed to erupt due to physical barriers in the eruption path of the molars or abnormal positions of teeth. The greater clinical impact on the patient is the mesial slope of the second molar. Common factors for mesial tilt of maxillary or mandibular second molars include: the first molars are missing after the second molars erupt; the first molar falls off in the dentition replacing period and no gap maintainer is placed; the second molar erupts over large inclination angle towards the mesial direction.
In the orthodontic clinical work, the mode of vertically inclining the second molar teeth to the mesial is commonly used, and the defects are as follows:
