Obturators

obturator
Floating obturator of the sky.

Obturators is a prosthesis used in defects of hard or soft palate. Obturators, closing the defect and risorsa mouth from the nasal cavity, promotes the normalization of breathing, eating, speech. When feeding infants with congenital defect of the sky (cleft) obturators in the form of a soft bib impose on the mother's breast, the exhaust from a thin rubber plate divides the oral cavity from the nose of the child. When artificial feeding this record attached to the horn (dummy). Obturators for permanent use have different designs. Defects in congenital cleft fill the so-called floating, i.e. mobile, obturator - thin plate, thick edges which a saddle-node cover the edge of the hard palate, and the rear part is retained by the ring-twitch muscles of the soft palate and the posterior pharyngeal wall (Fig.). Obturator appropriate to apply in the first days after birth - it protects children from inflammatory complications in the Airways and creates conditions for development of correct pronunciation. Adults with defects the hard palate used obturators in the form of a base plate made of hard plastic; with defects of both hard and soft palate that part of the obturator, which is designed for soft palate, is made of soft elastic plastic.

Obturators (from lat. obturare - plugging) - fixtures of various materials, intended to fill and clogging unnatural holes in the walls of the mouth cavity. O. needed to restore the functions of breathing, eating and speaking. O. sky applied with congenital cleft and partial penetrating the flaws hard or soft palate after damage and destroy disease processes (for example, gum).
Obturator - prosthesis of the upper jaw apply after resection of upper jaw neoplasm, rarely by gunshot wounds. Primitive ways of self-help, and first aid are composed in a temporary blockage of holes with gauze or other tissue, wax, sponge etc.,
Must be made of materials that meet the hygienic requirements. There are various designs O. depending on the shape, size and position of the defects. Currently, O. manufacture of plastics (polymethylmethacrylate), using the same methods of removing exact imprints edges of the defect and the surface of the heaven, and for the manufacture of removable dentures. Abdulrosa part can still be associated with a dental prosthesis; it must accurately, but without pressure snugly against the edges of the hole in the sky.
Gaps in congenital cleft palate fill the so-called floating, i.e. mobile, O. (Fig. 1) - thin plate, thick edges which a saddle-node grasp the edge of the hard palate, and the rear part is retained by the ring-twitch muscles of the soft palate and the back of the throat. The rear part of the floating obturator must be formed in accordance with the position and movements of the muscles of the soft palate and the back of the throat. It is advisable to use floating Acting before the eruption of the teeth (in the first days after birth) (Fig. 2). It protects children from inflammatory complications in the respiratory tract, in the hearing tube and middle ear and creates almost normal conditions for development in the future, the correct pronunciation.
Mobile suspended obturator (Fig. 3) apply with the opportunity to consolidate the support plate clasps on the teeth. To still palatal plate in the soft palate, the button
movably attached upper second piece of soft plastic covering
the soft palate cleft from the nasopharynx; when muscle contraction velopharyngeal valve this piece comes in contact with the back wall of the pharynx.
Acting for natural breast sucking mother represent rubber balloon (fill clearance gap and the lower nasal passage), coupled with a rubber tube to inflate (Fig. 4). In successful cases, sucking possible and under floating O.
