The invention discloses a mandible guiding forward and fixed orthodontic combined correction device, which comprises a maxillary correction device and a mandibular correction device, wherein the maxillary correction device comprises a first
metal joint crown and a palate rod which are arranged on a first
molar and a second
premolar or a second primary
molar, a first buccal tube (the formula is shown in the formula) and a pad are arranged on the first
metal joint crown, an
upper dentition main arch wire is arranged on the first buccal tube, (the formula is shown in the formula) and a power armis arranged on one side of the pad; the mandibular correction device comprises a second
metal joint crown and a tongue arch which are arranged on the first
molar and the second
premolar or the primarymolar, a second buccal tube is arranged on the buccal side of the second metal joint crown, a
lower dentition main arch wire is arranged on the second buccal tube, the second metal joint crown is provided with (the formula is shown in the formula) a blocking arm which matches with the power arm of the pad. According to the mandible guiding forward and fixed orthodontic combined correction device,the maxillary power arm and the mandibular blocking arm are matched to realize that the mandible is guided forwards, and the fixed correction is realized through the bracket, the
upper dentition mainarch wire and the
lower dentition main arch wire arranged on the
tooth surface, so that the device has the advantages of strong support, convenient operation, good correction effect, sound patient experience and the like.
