Description
Technical Field
The invention relates to the technical field of auxiliary devices for dental correction and treatment, in particular to a correction device for a depressed or elongated rear tooth.
Background
Often, individual teeth are required to be removed for correction before oral restoration or implantation, so that gaps are obtained, and occlusion is adjusted, so that implantation or restoration treatment can achieve a better treatment effect. For example, the abutment of a missing tooth (all "teeth" and "abutment" are taken together in a word, referred to in the art as a dental occlusion relationship, and read as he) is often elongated due to the absence of occlusal contact between teeth for a prolonged period of time, requiring depression of the elongated abutment teeth prior to restoration or implantation. In addition, the lower submerged teeth need to be stretched or pulled into place so that they can not only achieve a better abutment with adjacent teeth, but also restore the biting relationship of the lower teeth to the opposite teeth.
The traditional treatment scheme for depressing the upper teeth adopts a plurality of anchorage nails, and the upper teeth grinding is depressed in multiple directions, however, the lingual side of the lower teeth grinding is not suitable for implanting implantation nails due to the specificity of anatomical positions, so that one difficulty in orthodontic correction is often to combine complex fixed correction to adjust the position of the depressed lower teeth grinding. Traditional treatment regimens for stretching or pulling low-lying teeth are also often complicated by the need to incorporate complex fixed appliances to precisely adjust and control their three-dimensional positional adjustments, because either full-bite or full-mouth teeth (i.e., involving multiple adjacent teeth) require adhesive appliances, which are uncomfortable and not conducive to oral hygiene.
In view of the above problems, the present invention provides a device for correcting a low or extended back tooth, which adopts a dual-purpose structure, has an exact therapeutic effect, and can reduce the production of materials and the clinical treatment cost.
