Retention device

(Kosyreva T.F., Vasilyeva M.B., Voeikova O.V.)

The claimed utility model relates to medicine, directly to dentistry and orthodontics, and concerns the design of the retention device. The retention device consists of: a base 1 shortened from the roof of the mouth from photopolymer plastic and two rows of a reinforcing polymer filament 2 with a diameter of 0.35 mm, extending from the vestibular side, then continuing in the base of the device and covered with a photopolymer plastic in the cheek-b side of the crowns teeth 3 without overlapping their cutting edges and occlusal surfaces. The retention device provides an improvement in the result of the retention period after correction of various anomalies of the dentition and anomalies of the teeth.
