Abstract

The invention discloses a children interdental space retainer and belongs to the technical field of orthodontics. One end of the outer shell is in interference clamping connection with the preformed crown, a supporting spring, a telescopic rod and a connecting plate are arranged in the outer shell, one end of the telescopic rod is connected with the inner bottom face of the outer shell, the other end of the telescopic rod is connected with the connecting plate, and the outer side of the telescopic rod is sleeved with the supporting spring. The two ends of the supporting spring abut against the inner bottom face of the outer shell and the connecting plate respectively, the connecting plate is connected with one end of a screw rod, the outer side of the screw rod is in threaded connection with a nut, the other end of the screw rod is connected with a baffle, and the end face of the nut is rotationally connected with the outer end face of the outer shell through a bearing. The use length of the supporting spring is changed through driving of the screw, then the use length of the gap retainer can be changed along with jaw growth, the problem that in clinic, a child needs to see a doctor continuously and a new gap retainer needs to be manufactured due to growth and development is solved, the doctor seeing cost of a patient is reduced, and the chair-side operation time of the patient is shortened.

Description

Technical field [0001] The present invention relates to a children's teeth gap holder belonging to the field of oral orthodontic technology. Background technique [0002] The application date is January 19, 2020, and the application number is CN202020122614.8, which is a "a double-ended wire loop gap holder", China's utility model patent, disclosed: two sidewalls of the two wire circles The fixed grooves provided with fixed blocks, fixed blocks are fixed, respectively; both ends of the limit steel wire are provided with a bump used in combination with the fixed slot, and the bump is slidably connected to the fixed slot, and the bumps and fixed grooves One-way. Preventing the appearance of the teeth from growing during the growth process, avoiding the problems of the teeth that have not been neatly in the later teeth, or the teeth that are skewer affect the teeth of the constant tooth. [0003] However, in real, with the growth of child jaw, the teeth will be displaced, and the cl...
