Description

Orthodontic device for depressing or extending posterior teeth

Technical Field

The invention relates to the technical field of dental correcting and treating auxiliary instruments, in particular to a correcting device for depressed or elongated posterior teeth.

Background

Before oral restoration or implantation, individual tooth movement is often required to be corrected so as to obtain gaps and adjust occlusion, and thus, better treatment effect of implantation or restoration treatment can be achieved. For example, a missing occlusal (all "teeth" and "occlusal" are words taken together and refer to occlusal relationships in the art as he) tooth often has an elongated condition due to the absence of occlusal contact between teeth for a long period of time, and requires the elongated occlusal tooth to be depressed before restoration or implantation. In addition, the lower sunken teeth need to be stretched or drawn in place, so that the lower sunken teeth can obtain better adjacent relation with adjacent teeth and can restore the occlusion relation between the lower sunken teeth and the contra-occlusal teeth.

The traditional treatment scheme for depressing the upper posterior teeth adopts a plurality of anchorage nails, the upper molars are depressed in multiple directions, however, the lower molars are difficult to implant the implant nails due to the particularity of anatomical positions, and therefore, the orthodontic correction is difficult, and the positions of the depressed lower molars are adjusted by combining complex fixed correction. Conventional extended or pulled low profile treatment regimens are also often complicated by the need to incorporate complex fixed appliances for precise adjustment and control of three-dimensional position adjustment, since full occlusions or teeth (i.e., involving multiple adjacent teeth) require bonded appliances that are neither comfortable nor conducive to oral hygiene.

In view of the above problems, the present invention provides a depressed or extended posterior teeth appliance which has a dual-purpose structure, not only has a definite therapeutic effect, but also can reduce the production of materials and the clinical treatment cost.
