Problems solved by technology

In some cases, it is difficult to take into account the size of the corrective force at the traction point with the right direction. If the impacted teeth need to move to the buccal side, the traction point is preferably on the lip side, but because the

Abstract

The invention relates to the field of orthodontic tools, in particular to an embedded tooth traction device. The device is composed of a traction hook and an appliance, the traction hook is adhered to a dental crown of an embedded tooth needing traction, the traction hook is composed of an adhesion accessory and a ligature wire, one end of the ligature wire is tied to the adhesion accessory, and the other end of the ligature wire is free and bent into a hook. The appliance is composed of an elastic traction wire and a retention device, one end of the elastic traction wire is embedded in the retention device, and the other end of the elastic traction wire is bent and connected with the free bent end of the ligature wire on the traction hook. According to the device, the traction direction of the embedded teeth can be reasonably adjusted in a three-dimensional space, meanwhile, the embedded teeth in different dentition periods can be corrected, the requirement for anchorage teeth is low, and the device is easy to manufacture, low in price and remarkable in effect.

Description

technical field [0001] The invention relates to the field of oral orthodontic correction tools, and relates to a tooth correction device, in particular to a traction device for an impacted tooth. The device is also suitable for the correction of severely misaligned teeth. Background technique [0002] An impacted tooth usually refers to a tooth that has passed the eruption period, but is still embedded in the jawbone tissue due to the obstruction of adjacent teeth, bone tissue or soft tissue. It cannot be directly observed by the naked eye in the mouth, and it needs to be discovered by imaging examination. . The prevalence rate of impacted teeth is about 13.7-16.5% in foreign studies, and about 7.33%-9.61% in domestic big data case statistics. It is a common and frequently-occurring disease in oral clinical practice. The pathogenesis of impacted teeth is complicated. Common pathological factors include abnormal position of tooth germ, premature loss of deciduous teeth, infe...
