The existing front traction intraoral device is mainly divided into two main types of traditional tooth anchorage type and bone anchorage type, wherein most of traditional tooth anchorage type is adhered to teeth through a fixing appliance, and a traction hook made of metal and an outer mouth cover are used for elastic traction. The intraoral anchorage mainly originates from teeth and hard palate, indirectly transmits orthopedic force to the maxillary periosteum and surrounding bone seams, promotes subperiosteal osteogenesis and bone seam osteogenesis, thereby achieving the purpose of stimulating the development of the maxillary bone, and the defects are mainly represented in the following steps: 1. the intraoral device has large volume, is difficult to clean and easy to decayed tooth, and has poor comfort for patients; 2. the metal device is arranged in the mouth, so that potential dangerous factors such as ulcers, mistakes, impact injuries and the like are easy to occur to teenagers; 3. adverse dental effects such as extension and advancement of the molar, and increased tilt compensation of the upper and lower incisors are greater. The bone anchorage type is mainly characterized in that a micro-implant is implanted in a specific area of the maxilla, and elastic traction is carried out between the head of the implant and an extraoral front traction mask. Although the bone-supporting anti-bone treatment effect is remarkable and the dental adverse effect is reduced, the defects still exist: 1. anterior traction is mainly performed on teenagers with insufficient development of the upper jaw, which is an invasive operation, the infant has a certain problem in cooperation, and the implanted implant has the risks of infection and falling off; 2. the implanted implants are all metal and have influence on head X-ray shooting.

The utility model is further described below with reference to the drawings and specific examples, which are not intended to be limiting.
Referring to the illustration, the anterior traction arm device of the bracket-free invisible appliance comprises at least one cheek arm 1, one end of the cheek arm 1 is designed to be three-dimensionally printed in a one-piece type or detachably extended to the cheek area of the maxillary posterior teeth of the bracket-free invisible appliance 0, the other end extends towards the maxillary cuspid area, the outer end part of the cheek arm 1 extending towards the maxillary cuspid area is provided with a traction knot 2, and the traction knot 2 is used for fixing an elastic ring (rubber ring) and is connected with an external mask traction frame through the elastic ring.
In a preferred embodiment, and as shown with reference to FIG. 1, the buccal arm 1 is one piece and extends from the buccal side of the maxillary first molar or maxillary first premolars or maxillary second premolars of the non-bracket contact appliance 0 toward the maxillary cuspid region.
In another preferred embodiment, the buccal arms 1 are two, one extending from the buccal side of the maxillary cuspids of the non-bracket contact appliance 0 and the other extending from the buccal side of the maxillary first molar or the maxillary first anterior molar or the maxillary second anterior molar of the non-bracket contact appliance 0, the two buccal arms 1 meeting at a point where the traction junction 2 is located where the two buccal arms 1 meet. It will be appreciated that the arrangement described above allows for an angle between the two cheek arms 1, the angled design of the two cheek arms being better able to incorporate and utilize the anchorage of the overall dental arch.
The traction force point of the cheek arm 1 is as close as possible to the maxillary impedance centre. Specifically, the height of the traction knot 2 and the cheek arm 1 and the sagittal position where the cheek arm 1 merges are as close to the maxillary impedance center as possible according to the depth of the vestibular sulcus of each person, and when the application point of traction is as close to the maxillary impedance center as possible, the curative effect of anterior traction is optimal, which is more favorable for realizing the overall movement of the maxilla. The impedance center of the maxilla is a center point in biomechanics, and the impedance center refers to the center of motion resistance restrained around an object when force acts on the object and does not change with external force. The three-dimensional coordinate value of the impedance center of the maxilla is on the median sagittal plane, the height of the impedance center is at the lower edge of the pyriform hole, and the front-rear position is between the second premolars and the first molars. The anterior traction of orthodontics is mainly used for enabling the maxilla to grow and move in the sagittal direction, and the traction force point is closer to the center of resistance of the maxilla, the maxilla is more likely to move.
