METHOD FOR MANUFACTURING G.V. STEPANOV'S THERAPEUTIC RETAINER Russian patent published in 2015 - IPC A61C7/00 

FIELD: medicine.

SUBSTANCE: method for manufacturing a therapeutic retainer involves taking an impression of a jaw, making working and diagnostic casts, creating a preparation depot, forming and cutting a retainer. Before creating the therapeutic preparation depot, a clinical contour height included into the therapeutic retainer is detected on the working cast with using a parallelometer; the therapeutic retainer is bordered on the working cast: the first border from vestibular and buccal surfaces 2 mm above the transitory fold on the lower jaw and 2 mm below the transitory fold on the upper jaw, avoiding all mucosal cords and frenulums; the second border from the lingual surface is marked along the alveolar process of the lower jaw 1-1.5 mm above the mouth floor or for the upper jaw on the palatal surface is marked 10-15 mm short of the line A. The borders are marked to deposit a therapeutic preparation: on the lower jaw - from the vestibular, buccal and lingual surface from the gingival crest to the transitory fold along the alveolar process within a projection of dental roots or on the upper jaw - from the vestibular, buccal or palatal surfaces from the gingival crest to the transitory fold along the alveolar process within the projection of dental roots. The space for depositing the therapeutic preparation is created so that it stops 1-2 mm short of the border of the therapeutic retainer; between the therapeutic preparation depot borders marked on the cast, a layer 0.5-1 mm thick of a silicone impression compound is placed; the working cast is placed into a vacuum moulder; the cast is crimped with a thermoplast; the therapeutic retainer is cut along the borders marked on the casts; a relief incision is made from the first left molar to the first right molar along the vestibular surface of the therapeutic retainer above the marked clinical contour; the therapeutic retainer is ground and polished.

EFFECT: invention provides ensuring a low risk of deformities by using a single thermoplastic plate with no additional elements introduced, and also promotes maintaining the optimum drug concentration by making the space within the projection of the dental roots.
