Also has a hook on each molar allowing the apparatus remains fixed. The great advantage of this retainer is that it allows some ability to move, if there is any small relapse.
Fixed retainers consist of a small gold wire or stainless steel that attaches to the inside of the teeth. Depends on the case will be placed only in incisors or canines will run through the first premolars or.
Control after orthodontic treatment
Removable retainers must be worn full time for the first two months and after that period, reduce nighttime use only. It is recommended to be used indefinitely, even after three or four years, you can start to reduce their use if advised by the specialist in dentistry and stomatology .
As it relates to the fixed retention, it will be full time from the time of placement. Your orthodontist will explain how to sanitize the area, either by using floss or interdental brushes to prevent the accumulation of calculus.
