摘要

Metal wire teeth brace is manufactured in different sizes, for patients of different ages comprises a bow of one of the following alloys: (i) Chrome cobalt alloys (e.g. blue Elgiloy); (ii) beta titanium alloys, e.g. TMA; (iii) flexible nickel-titanium alloys, e.g. m-Niti; or (iv) stainless steel alloys. Metal wire teeth brace is manufactured in different sizes, for patients of different ages and the tooth bow size. The brace comprises wire of minimum strength 0,017 x 0,025 inch and max. strength 0,021 x 0,025. The wire bow comprises one of the following alloys: (i) Chrome cobalt alloys (e.g. blue Elgiloy); (ii) beta titanium alloys, e.g. TMA; (iii) flexible nickel-titanium alloys, e.g. m-Niti; or (iv) stainless steel alloys. The wire bow is inserted into mouth on certain teeth (a) in front: on the brackets of the teeth no. 21/12 and (b) in the back: into the tape auxiliary tubes of the teeth no. 6/6. The bow does not contact the remaining teeth, brackets or tapes. The wire bow bends downward behind teeth no. 2/2 and to the height of the cut edge of the teeth no. 2/12 vertically, and runs horizontal for 2-3 mm. Then the wire turns upward again, and runs horizontal to the rear on a somewhat higher level than the height of the front section of wire, which runs between the teeth 2/2, so that it runs somewhat higher than the slot of the Bracket of the teeth No. 5/4/3/3/4/5.
