Problems solved by technology

The above methods have the following disadvantages: (1) It is necessary to take X-ray film / CBCT (cone beam ct) to determine the position of the tooth root, which is costly and has a large radiation; (2) The positioning is not accurate, which can easily lead to improper placement of implant screws; (3) The positioning device needs to be made according to the shape of the crown, and the cooperation of the technician is required, and the operation time at the chair is long
(4) All need personalized production, high cost and no marketing value
In summary, there is no ideal micro-screw implantation device and positioning method at present.

Embodiment Construction

[0037] Attached below Figure 1-9 The present invention is described in further detail.

[0038] A planting nail positioning device, including a planting nail implanter, the planting nail implanter can refer to the prior art, like Ormco The planting nail implanter is mainly composed of three parts: the handle 1, the booster 2 and the fixing rod 3. In order to realize the positioning function, the present invention adds a planting nail positioning system ( see figure 1 ), the positioning system mainly includes a casing 4, a casing limit rod 5 and a positioning rod 6; the casing 4 is hollow and consists of a long casing 4-1 below and a short casing 4-2 above; The casing 4-1 and the short casing 4-2 are fixedly connected; the central cavity of the long casing 4-1 is provided with a fixed rod 3, that is, one end of the fixed rod 3 passes through the lumen of the long casing 4-1, When the casing limit rod 5 is not fixed with the planting nail implanter, the long sleeve 4-1 ca...

Abstract

The invention discloses a planting nail positioning device and relates to the technical field of orthodontic treatment. The planting nail positioning device comprises a planting nail implanter and ischaracterized by also comprising a sleeve, a sleeve limiting rod and a positioning rod, wherein the positioning rod is formed by a horizontal arm and a vertical arm. With simple structure and reasonable design, the device can remarkably reduce risk of injuring the root of adjacent tooth in a planting process, so as to realize accurate positioning and guide the implantation of the planting nail; meanwhile, the device shortens time of operation next to a chair, and has the advantages of convenience in operation, high practicability, great value in clinical application and broad market prospect.

Description

technical field [0001] The invention relates to the technical field of orthodontics, in particular to an implant nail positioning device and a positioning method thereof. Background technique [0002] With the development of micro-screw technology, implant screws are more and more widely used in the field of orthodontics, mainly used to enhance the anchorage of posterior teeth, retract the upper anterior teeth, move the upper and lower dental arches, depress the anterior teeth, molars, etc. , The application of implant nails has also achieved remarkable clinical results. However, in the prior art, there is a risk of damaging the root of the adjacent tooth during the implantation of the micro-implantation screw, causing the root of the adjacent tooth to resorb, or even loosening and extraction. For some patients with buccal soft tissue hypertrophy and limited mouth opening, traditional implantation techniques are also significantly limited, and even treatment can only be giv...
