Corrector for correcting maxillary skeletal width disorder

Abstract

The invention discloses a corrector for correcting maxillary skeletal width disorder. The corrector comprises an expander, an implantation nail, a positioning guide plate, an implantation guide plateand transparent tooth sockets; the arch expander is fixed to the upper jaw of a patient through the positioning guide plate; then the implantation guide plate is connected with the positioning guide plate; the implantation guide plate determines the implantation position of the implantation nail; the implantation nail is implanted; and the positioning guide plate and the implantation guide plate are taken down. After fixing of the expander is completed, the transparent tooth sockets are worn on the teeth of a patient; firstly, seam expanding tooth sockets are worn sequentially, so that the gapbetween the two middle incisions is gradually increased along with the left and right upper jawbones which are gradually far away from each other after being expanded; and then closing tooth socketsare worn to gradually close the gap between the two middle incisions of the patient. The patient wears the transparent tooth socket to avoid mesial movement of the crowns of the middle incisions, andthe tooth roots of the middle incisions are gradually gathered under traction of gingival fibers, so that the requirement of root controlling movement of the middle incisions in the later period is reduced, the treatment course is shortened, and the pain of the patient is relieved.

Description

technical field [0001] The invention relates to the technical field of a maxillary width appliance and its peripheral accessories, in particular to an appliance for correcting maxillary width disorder. Background technique [0002] Maxillary Skeletal Expansion (MSE) is a new type of device for maxillary bone expansion. The expander is fixed by four implant nails that vertically penetrate the double-layered cortical bone of the maxillary bone. It is directly transmitted to the jawbone, directly opens the palatal suture, and realizes the effect of bony arch expansion. This kind of bony expander expands the age limit, and the success rate of arch expansion is nearly 100% in the case of unclosed palatal suture, and about 85% in the case of closed palatal suture, basically avoiding the traditional bone expansion The required palatal suture split surgery greatly minimizes trauma. [0003] However, the current clinical use of MSE has the following problems. One is the high posit...

Problems solved by technology

Traditionally, multiple steps such as trying on the ring, taking the impression, pouring the model, and making it by hand in the processing factory are not only tedious and time-consuming, but also increase the possibility of errors

Second, there is a high requirement for the accuracy of the implantation angle of the implantation nails

Third, because the first molars on both sides are used to make the positioning rods of the expander, a tooth-bone hybrid support type expansion device is formed, which not only causes the inevitable partial dental expansion effect, but also in the first three stages of expansion. For months, the twist or misalignment of the first molars could not be corrected, prolonging the course of orthodontic treatment
