Face rack type tractor for burying impacted tooth

Abstract

The invention provides a face rack type tractor for burying an impacted tooth. The tractor comprises a casing, wherein the casing is mounted on a face rack; one end of a transverse support rod is vertically fixed on the casing; the other end of the transverse support rod is hinged with one end of a telescopic rod through a first spheric joint; a first connecting ring is arranged at the other end of the telescopic rod; the first connecting ring is sleeved with a second connecting ring which is mounted at one end of a force measuring traction rod; the other end of the force measuring traction rod is hinged with an impacted tooth holding mechanism through a second spheric joint. By adopting the tractor provided by the invention, traction can be carried out on the basis of a conventional facerack, and the tractor can be adjusted for 360 degrees outside a mount according to demands; the facial arch outside the mouth is adopted as anchorage to tract the impacted tooth, so that side effectscaused by a tooth arch as the anchorage are avoided; meanwhile, the traction force can be adjusted by a mechanism inside the mouth according to demands, the barrier of tooth movement can be avoided asmuch as possible, and adjacent tooth root absorption can be avoided.

Description

technical field [0001] The invention belongs to the field of medical aids and relates to an impacted tooth, in particular to a surface frame retractor for an impacted tooth. Background technique [0002] Impacted teeth are common dental and jaw deformities, which can occur in any position of the whole dentition. These dental and jaw deformities will seriously affect the facial appearance and masticatory function, and often affect the health of adjacent teeth. Early treatment of impacted teeth is very important for the prognosis of impacted teeth and adjacent teeth. The earlier the orthodontic treatment is started, the better the effect. Early orthodontic treatment can adjust the position of the tooth root, so that the impacted teeth and adjacent teeth are out of contact, and the undeveloped tooth root can promote its final root growth potential, so that the tooth root can continue to develop. Otherwise, short roots, curved roots, and even root resorption will inevitably occ...
