Description
Technical Field
The utility model belongs to the technical field of medical instrument for the oral cavity, concretely relates to ware is rescued to upper jaw embedding impacted tooth improvement formula nance arch.
Background
Maxillary incisors and cuspids, commonly referred to as "social sexes," have an effect on the appearance, vocal function, and mental health of patients with maxillary embedded central incisors. For some embedded maxillary central incisors, the untimely treatment can cause the absorption of roots of adjacent teeth and the formation of dental cysts, and even affect the development of the maxillofacial region of a patient. The embedded impacted middle maxillary incisors often need to be moved in a large range, and the correction difficulty is large. At present, the common method is to treat the embedded tooth by combining a surgical windowing mode with an orthodontic traction mode, the method of traction of the embedded tooth to a normal position is generally fixed correction, and the fixed correction is divided into three types according to anchorage positions, but the methods have some defects:
traction of a main arch wire: the dentition is used as anchorage, and the traction device of the embedded tooth is connected to the main arch wire through an elastic wire, an elastic ring, a tension spring and the like for traction. The disadvantages are as follows: the traction direction is difficult to control, the anchorage is insufficient, local opening and closing are easy to cause, and adjacent teeth are pressed down; and bending on the stainless steel primary archwire can easily lead to labial irritation.
And (3) traction between the jaws: the mandibular dentition or mandible was used as an anchorage. The jaw traction taking the lower jaw dentition as anchorage is to traction the embedded teeth by applying a main arch wire of the lower jaw dentition; or the jaw traction taking the lower jaw as anchorage is to implant micro-implants among the roots of 2 middle incisors of the lower jaw to draw the embedded teeth. The disadvantages are as follows: the direction of the traction force is difficult to control, and a patient can form larger traction force when opening the mouth, which is easy to cause the tooth to be buried, the force application tooth to be loosened or the tooth root to be absorbed; the traction device is inconvenient for the patient to eat.
Planting anchorage: and (4) performing invasive operation.
Guide rod type appliance: the first molars on two sides of the upper jaw and the mucous membrane on the palatal side are used as anchorage, and the anchorage comprises a nano-arch, a plastic palatal support, a fixed lock groove block, a guide rod and a traction device. The hard palate is used as an anchorage part, and the direction can be adjusted by adjusting the positions of the fixed locking groove block and the guide rod, so that the traction of the embedded teeth is facilitated. The disadvantages are as follows: the operation needs to be carried out in the mouth, the operation is inconvenient, the manufacturing cost is high, and the operation is complicated when the position is adjusted by applying force every time.
SUMMERY OF THE UTILITY MODEL
To the problem that exists among the prior art, the utility model aims to provide an ware is rescued to upper jaw embedding impacted tooth improvement formula nance bow, should rescue the ware and can carry out reasonable adjustment to correcting the power direction on three-dimensional space to can not be by the problem of traction movement when avoiding current treatment impacted tooth, need not regard as anchorage with dentition or dental arch simultaneously, can greatly improve the treatment success rate of incisor in the impacted tooth embedding upper jaw.
The utility model discloses a following technical scheme realizes:

The improved nance arch appliance for the maxillary embedded impacted teeth is characterized in that the horizontal arm is formed by bending a metal wire twice and comprises a closed end and an open end, the closed end is positioned at the extension part of the labial side, and the open end is embedded in the plastic palate support.
The improved nance arch appliance for the upper jaw embedded impacted teeth is characterized in that the traction device is a palatal ring-shaped guide rod, the palatal ring-shaped guide rod is formed by bending a metal wire of a horizontal arm, and the position of the palatal ring-shaped guide rod can be adjusted according to a traction eruption path to avoid adjacent tooth resistance and control on moment in the traction process.
The improved nance arch appliance for the maxillary embedded impacted teeth is characterized in that the palatal support ring-shaped guide rod is arranged at one end close to the plastic palatal support.
The improved nance arch appliance for the upper jaw embedded impacted teeth is characterized in that the palatal ring-shaped guide rod is bent spirally.
The improved nance arch appliance for the upper jaw embedded impacted teeth is characterized in that the palatal ring-shaped guide rod is bent in a double-spiral shape which is overlapped up and down.
The utility model discloses utilize orthodontic nance bow plastics palatal support commonly used clinically to hard palate as anchorage, avoid the tradition to correct and use adjacent tooth as the shortcoming of anchorage, solved anchorage and lost and anchorage not enough scheduling problem. Simultaneously, the L type horizontal arm that nance arch stretched out can prevent to lead the eruption hook to the palatal side and move, force and moment when guaranteeing clinical afterburning, and can avoid the oppression of thrust augmentation device to palatal side mucous membrane, thereby avoid alveolar bone and the risk that the gum loses as far as possible, and the ring shape guide arm structure, be convenient for according to the actual position of tooth clinically, can be through the position of adjusting terminal traction point on the three-dimensional space, the direction of control traction force, reduce the resistance that the tooth removed, the total scope of the afterburning of also greatly increased tooth.
