The present invention relates to an improvement of a lingual bracket for a molar tooth for coupling an orthodontic wire by being bonded and fixed to the lingual side of a last molar tooth for lingual orthodontics, particularly, for fast and easy coupling of a wire on a lingual bracket for a molar tooth. To this end, the present invention provides the lingual bracket for a molar tooth comprising a head unit on a base unit, wherein: a coupling groove is formed in a parallel direction to the base unit, that is, in a vertical direction on the center of the head unit such that inner support pieces and outer support pieces are formed on both sides thereof; and curved upper locking hooks are formed toward the base unit on the upper ends of the inner support pieces and lower locking hooks having guide grooves are formed on the lower parts of the outer support pieces, so that, during use, the lingual bracket for a molar tooth is bonded and fixed to a side portion of the molar tooth by using the base unit and an end of a wire located on the lingual side is inserted into the vertical coupling groove having an open top and is coupled by using coupling rings. |
