Description

That is, in FIGS. 15 to 19, reference numeral 21a denotes a retainer for upper jaw teeth, and reference numeral 21b denotes a retainer for lower jaw teeth. The upper teeth retainer 21a is a substantially U-shaped metal support in which both ends 25a of the wire portion 23a contacting the outer side surfaces 5a of the upper teeth 3a, 3a, ... are located inside the upper teeth 3a, 3a. linked to part 27a, the said metallic support portion 27a fixed upper dental 3a, 3a ... inner surface 7a, 7a ... are compatible irregularities 29a, 29a ... synthetic resin portion 31a having a said wire portion 23a The upper jaw teeth 3a, 3a, ... are inserted into the gaps 33a between the projections 29a, 29a, ... of the synthetic resin portion 31a. On the other hand, the lower jaw retainer 21b is a substantially U-shaped metal in which both ends 25b, 25b of the wire portion 23b in contact with the outer surfaces 5b, 5b of the lower teeth 3b, 3b, ... are located inside the lower teeth 3b, 3b, ... linked to manufacturing support portion 27b, the lower jaw teeth 3b, 3b ... of the inner surface 7b, 7b ... are compatible irregularities 29 b, the synthetic resin portion 31b having a 29 b ... is fixed to the metallic support portion 27b, the wire The lower jaw teeth 3b, 3b, ... are inserted into the gaps 33b between the portions 23b and the irregularities 29b, 29b, ... of the synthetic resin portion 31b.

The wire portions 23a and 23b are formed of, for example, a cobalt chrome alloy. The metal supporting portions 27a and 27b are formed of, for example, a titanium alloy, a cobalt chromium alloy, or a PGA (platinum alloy). The synthetic resin portions 31a and 31b are formed of, for example, a material having appropriate flexibility such as polycarbonate and acrylic resin.

A metal third reinforcing member 39, 39 whose one end 39 'is fixed to the metal supporting portion 27a is penetrated through the synthetic resin portion 31a of the upper jaw retainer 21a, and the synthesis of the metal third reinforcing member 39, 39 is performed. The other end 39 '' projecting from the resin portion 31a is fixed to the wire portion 23a.

In order to achieve the above object, the maxillary dental retainer of the present invention comprises a wire of the lip line contacting the outer surface of the tooth, and a reinforcing wire provided with the concavities and convexities fitted on the inner surface of the tooth and the inter-clasp bridge. Of the above-mentioned reinforcing wire extending from the C-clasp on the lip side, crossing the palate posterior edge, consisting of a palatal edge resin floor which is largely hollowed out leaving only 4-5 mm from the outer edge embedded with the crosslinking wire, the labial lines of wire were placed along the vicinity of teeth tooth neck section is wax wearing each other and are embedded in the interior of a given said marginal resin bed, the resin edge of the dentition side tooth neck portion is anterior, posterior teeth is to minimize resin thickness by up to crown contoured portion.

In addition, the lower jaw dental retainer according to the present invention is formed by using a lip of the wire in contact with the outer surface of the tooth and an outer peripheral edge of the reinforcing wire embedded with the concavities and convexities matching the inner surface of the tooth. consists of a palatal edge resin bed in the form of hollowed the most leaving only 5 mm, the reinforcing wires extending from C clasp labial, said that along a vicinity of teeth tooth neck portion of the labial lines wires are wax wearing each other and are embedded in the interior of a given said marginal resin bed, the resin marginal teeth neck part is anterior of the dentition side, the resin thickness and posterior portion until crown contoured portion It was minimized.

Wire 104 along a vicinity of teeth tooth neck are the C clasp 100 Jiro wear.

Wire 108 along a vicinity of teeth tooth neck portion is the C clasp 105 Jiro wear.
