English to Portuguese translations [PRO] Medical - Medical: Dentistry / distalização dos molares superiores
English term or phrase:lingual sheath
It consists of a Nance button that incorporates four occlusal rests that are bonded either to the deciduous molars or to the first and second bicuspids. An alternative method is to solder retaining wires to bands on the maxillary first bicuspids. Two TMA 0.032" springs inserted into an 0.036" lingual sheath on the maxillary molar bands are used as active elements for molar distalization. The springs are mounted as close to the centre and distal edge of the button as possible to produce a broad, swinging arc (or pendulum) of force.
