Traditional braces retainer

In oral clinic, after the orthodontic bracket is removed, it is necessary to put on the retainer in time to maintain the corrective effect! At present, there are mainly: 1, self-setting resin and steel wire bending bracket for doctors. Due to the poor material, these stents are rough to make, and they have a strong foreign body feeling after wearing them, and they stink at a little time; 2. The retainer made of thermosetting material and steel wire filling glue has no peculiar smell, but it is generally rough and does not fit, with poor retention and poor effect; 3. The transparent retainer (pressed retainer) made of transparent colorless film is beautiful, not easy to be detected, but easy to be damaged. It needs to be made repeatedly, and it is easy to rebound with poor strength, and there are other clinical correction defects; 4. The Harry's retainer made of imported special corrective materials and steel wire inherits the traditional professional design, which is scientific and reasonable, with good retention, excellent selection of materials, exquisite production, no odor, light and comfortable fit!
