METHOD FOR APPLYING FIXED RETAINER MADE FROM FIBROUS TAPE Russian patent published in 2014 - IPC A61C13/38 

FIELD: medicine.

SUBSTANCE: plastic impression tray is prepared by dissecting its sides. A vestibular border is dissected on the remained front side. A wax tape is adhered on the middle of a lingual surface of front teeth. The prepared impression material is applied on the tray. The tray is introduced from the side of the oral cavity outside until the material fills the space above cutting edges. The impression is delivered back; and the wax tape is mechanically removed from the impression. A fixed retainer is prepared and placed into a slot on the impression. The teeth to be splinted are prepared. The impression is inserted with a fibrous tape and mounted on the teeth. The fibrous tape is polymerised with halogen light from the outside through interdental spaces. The impression is removed, the fibrous tape is additionally polymerised with halogen light from the side of the oral cavity. An excessive length of the polymerised fibrous tape is dissected, and a surface of the fibrous tape is treated with a layer of adhesive composite. By using the elastic silicone impression for the fibrous tape adaptation, the method enables preserving a natural surface structure of the splinted teeth and positioning the fibrous tape of the slot-free retainer exactly on the teeth by abrasion of solid dental tissues.

EFFECT: stabilising the teeth after orthodontic care.
