In the oral orthodontic clinical work, in order to solve the problem of fixed orthodontic oral hygiene, the author made a toothbrush with fixed orthodontic treatment. Production method: 1, take a regular children’s health care toothbrush, with a sand blade along the brush head on both sides of the two rows of bristles (a total of three rows of bristles, wide 10.5L) of the root, the brush head on both sides of the plastic and bristles from the head to the handle to cut to the brush neck of the narrowest place, leaving only a row of bristles in the middle of the brush, the brush head the rest of the width of 4.5-5.5L. 2, with a diamond grinder will be the head of the brush two cutting surfaces and edges and corners of the grind grinding grinding round. 3, with scissors will stay in the middle row of 9 pairs of hairs every other handful of cut a handful, each handful of cut short 2L in order to brush the teeth when the bristles to the two neighboring teeth and arch wire formed within the triangle gap, orthodontic toothbrush production is complete. Second, the use of patients to brush the teeth first with an ordinary toothbrush brush each tooth lip, cheek, tongue, jaw and other surfaces, and then use the orthodontic toothbrush to remove the ordinary toothbrush can not brush the dead corner of the inlaid or retained material. Modification and application of bracket forceps In the process of bracket bonding, orthodontists often use conventional oral forceps or replace them with other forceps, which often lead to bracket slippage due to the smooth beak of the forceps. In view of this, the authors used oral forceps to reformulate into a special forceps for holding brackets – bracket forceps. The beak of the bracket forceps consists of a forceps cone and a forceps blade, which prevents the adhesive from blocking the bolus channel or ligating the silk groove. Tweezers cone for holding Begg groove (see Figure A); tweezers edge for holding square wire groove (see Figure B). During operation, the bracket forceps enter the oral cavity horizontally, parallel to the jaw plane, place the bracket correctly on the buccal and labial surfaces of the orthodontic teeth, and gently release the forceps beak after stabilization. This forceps has been applied to the bonding of clinical brackets in our department, and no bracket slipping phenomenon occurred. Plaster saw and ligature wire end bender homemade method Plaster saw: take a section of 1.8L stainless steel wire, the left side bent into a bow, the right side bent into a rectangular grip handle. In the grip handle between the steel wire welding two short steel wire to increase the fixed position, in the steel wire at the beginning of the end of the surface of each grinding a small groove, the teeth with ligature wire at the left end of the small groove on the winding of the two circles, two strands of twisted fixed at the end of the steel wire on the groove. The ligature wire can be replaced at any time if it breaks during use. Ligation wire end bender: take 1.8L stainless steel wire 10CM, both ends are hammered flat. One end of the edge flattening, in which the point of grinding a notch, leaving the notch end of the wire 2cm, the rest of the self-coagulating plastic embedded plastic handle made of round or polygonal, the length of about 10cm, to be plastic hardening grinding and polishing surface. When in use, the hand holding the plastic handle can be ligated wire end to each direction of the bend. Breast tooth stump cutting pliers converted bracket removal pliers Fixed orthodontic bracket removal is a laborious and time-consuming task. Our department will cut off the root of the stump of milk teeth by restructuring instead of bracket removal pliers, after more than one hundred cases of disease trial, the effect is good. Methods: Shandong Xinhua Instrument Factory production of milk teeth extraction pliers No. 6, that is, milk teeth stump cut off pliers, pliers beak end of the shear on the inner surface of the edge plane, with a fine grinding wheel grinding into about 45 degrees of inclined surface can be. When the trial period of time, the edge of the blunt, but also can continue to sharpen.
