The present invention relates to a tension adjusting device for use in a orthodontic maintenance device to limit the required position of the tooth after the correction or to expand the dental arch.

After the orthodontic patient completes the orthodontic treatment with the orthodontic device, the orthodontic device is removed. The orthodontic patient needs to use the orthodontic maintainer for a period of time other than the unavoidable condition of eating or brushing. Each of the posterior teeth is placed in a neat position in the upper and lower dentitions to avoid re-displacement of the teeth after correction. In addition, after the orthodontic treatment, the patient with the upper and lower dentitions must also use the orthodontic maintenance device (or the dental arch expansion maintainer) to gradually expand the upper and lower arches, thereby adjusting the upper and lower teeth. The shape and position of the column enable the upper and lower dentition rows to be aligned neatly.

The presently known configuration of a orthodontic maintenance device includes two oppositely arranged tooth row arranging members and a force adjusting device coupled between the two tooth row arranging members, the tension adjusting device being two connecting members thereof They are respectively fixed in the two-tooth row fittings, a spring is provided between the two connecting members to provide tension, and a round rod is connected between the two connecting members, and the two connecting blocks are respectively adjusted and positioned by the plurality of screws on the round rod. The relative position on the round rod, thereby changing the tension of the tension adjusting device to apply force to the two tooth row fittings.

The existing tension adjusting device applied to the orthodontic maintenance device is a small device. When the dentist performs the tension adjustment of the orthodontic maintenance device for the orthodontic patient, the dentist must use a small tool to remove the original two positioning blocks respectively. After the screw on the round rod is removed, change the position of the connecting block on the round rod, re-lock the screw to fix the two connecting blocks on the round rod, increase the spacing between the two connecting blocks, thereby expanding the large orthodontic maintainer The dentition sleeve.
