Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tooth correction, in particular to a kind of implant nail and its use method. BACKGROUND

[0002] The main purpose of orthodontics is to correct teeth, relieve malocclusion, and the core of the orthodontic process is tooth movement. In order to accurately control the movement of teeth and not to affect the position of other teeth by the reaction force, an external anchorage structure is needed to apply force to guide the teeth, so as to resist the reaction force generated in the orthodontic treatment process. Effective anchorage control is the guarantee of the success of orthodontic treatment. In clinical practice, the cost of micro-implant anchorage is low, the implantation operation is simple, the postoperative removal is easy, the impact on the quality of life of patients is small and it can provide stable anchorage. As a special anchorage, micro-implant nail provides a new idea and new tool for the development of orthodontics. The bone anchorage implanted in the jaw bone makes it possible to have "absolute anchorage". "Single operation, self-tapping design, immediate load" has become the mainstream direction of the development of micro-implant nail. Because of its simple operation, little discomfort and flexible anchorage, it has been widely used in closing the space between the teeth, retraction of the front teeth, uprighting of the molars and other aspects, constantly meeting the various needs of orthodontic treatment, and has been fully confirmed by clinical practice. Therefore, the present application provides a kind of implant nail and its use method.

[0003] In the prior art, a patent file with publication number CN104688364A and publication date of June 10, 2015 is proposed to solve the above technical problems. The technical solution disclosed in the patent document is as follows: a kind of orthodontic micro-implant anchorage nail. The anchorage nail includes anchorage nail head, anchorage nail neck and anchorage nail thread part. The anchorage nail head is composed of a solid cuboid with a thickness of 2mm. One corner of the cuboid near the neck is missing. This design is adapted to the inclination of the gum mucosa surface at the implant site, avoiding the compression of the gum by the geometry of the surface of the implant, causing inflammation of the mucosa, and being more conducive to cleaning around the anchorage nail. The top of the anchorage nail head is narrowed to form a ligation head. The trans-gum part of the anchorage nail neck is smooth in shape, 2mm long, and has an antibacterial biological coating on the surface to prevent plaque formation. The thread part of the anchorage nail includes a cortical bone segment and a cancellous bone segment. The cortical bone segment is a 2mm long continuous thread structure, and the remaining cancellous bone segment is a sparse thread structure. This structure is more conducive to the stability of the anchorage nail and reduces the shedding rate of the anchorage nail.

[0004] In order to solve the problem of easy shedding of the implant nail, the prior art uses the method of setting the ligation head of the anchorage nail, the cortical bone segment of the anchorage nail thread part and the cancellous bone segment of the anchorage nail thread part to cooperate with each other. However, the many limitations of the implantation site of the implant nail make the clinical traction very inconvenient, which further affects the patient's correction. SUMMARY
