| 摘要 |
The invention discloses braces for dentifacial functional orthopaedic and periodontal treatment made of natural or synthetic, flexible and food material, generally consisting of a double cradle (or trough), these two cradles having externally, in a plane, a flaring U-shape and separated by a thick horizontal partition (3). They are characterised in that: (a) the portion of the cradle designed for receiving the lower incisors has a limited curve, and, preferably, the shape of a straight channel (4); (b) the length of the channel designed for receiving the lower incisors is sufficient for fitting in the lower four incisors; (c) the height of the side lingual (2) and vestibular (1) partitions defining the channel designed for receiving the lower incisors (4), from the thick horizontal partition (3), is at least equal to the height of the incisors up to their neck.
