Description

The track elastic force spring of mouth cavity orthodontic balance appliance

Affiliated field:

Be employed rectification parts when when wrong jaw is ground one's teeth in sleep in rectification, moving near far away in the stable equilibrium appliance in the mouth cavity orthodontic field.

Background technology:

Clinically at present, few to the method for correcting the distomolar malposition, utensil mainly contains the elastic force rod and at the arch wire end curved the completion is set.Because the morphology factor of mandibular bone restriction; At the Horizontal Branch of mandibular bone and the exchange area of ascending branch; Just third molar zone adopts arch wire to place curved form to correct low level and hide third molar or other of impaction and grind one's teeth in sleep, and curved compressing gingiva takes place usually and stops maybe can't implementing operation.In upper jaw zone because of operating difficulties too in too remote; Use the elastic force rod to use arch wire curved relatively; The use of elastic force rod is than the curved easy point of arch wire, but the elastic force rod can only reverse the axial of tooth body, to corrigent process prerequisite is provided; Can not torsional axis in closing gap, need to change utensil and could accomplish correcting process.Say that objectively the limitation that these two kinds of methods exist is relatively large in corrigent process.In recent years adopt implant anchorage to increase the outer anchorage of jawbone and accomplish moving of grinding one's teeth in sleep; Though the method can provide new anchorage point; But the cost cost is too high and operation requires also high; Universal comprehensively clinically still difficult, the raising overall clinical level that the advantages of simplicity and high efficiency operator scheme could be faster and better.

Summary of the invention:

According to the grind one's teeth in sleep dissect physiology form in district of physical mechanics principle and oral cavity; Grind one's teeth in sleep with the oral cavity and to make demands before the stabilizing to of dissect physiology form in district;, simple efficiently for requiring with the physical mechanics principle with clinical manipulation for instructing thinking, manufacture and design track elastic force spring according to clinical situation of grinding one's teeth in sleep the district.Track elastic force spring is made up of interior spring, outer spring, rail silk and rail chair.The interior spring spring body of spring outside is inner, and the rail silk is inner at the spring body of interior spring, and rail chair is at the free-end of interior spring with outer spring both sides, and the bulk shape of interior spring and outer spring is a circle.The spring silk is that diameter is 0.25 millimeter a high-elastic steel wire; The steel wire of interior spring is shorter than the steel wire of outer spring, and the steel wire of interior spring is grown into 6.2 millimeters spring body through rotary winding shape, and the diameter of circular hole is 1 millimeter in the spring body; Every steel wire of spring body is arranged side by side; Middle no gap, the spring silk free-end of interior spring is that level is stretched out, the horizontal line that the parallel spring body of the free-end that level is stretched out is arranged; Two free-end horizon distances equal 1 millimeter of the diameter of circular port in the spring body, and are parallel with two horizontal lines that the spring body forms respectively at norma lateralis two free spring silk horizontal lines.The spring body diameter of bore of interior spring is 1 millimeter, and the circular overall diameter of interior spring is 1.5 millimeters.Circular port is greater than the overall diameter of interior spring in the spring body of outer spring, and the diameter of circular hole is 1.5 millimeters in the spring body of outer spring, and there is a bending at two end dissociative places of outer spring; The center of circle is crooked 0.55 millimeter in the outside spring spring of this bending body; The horizontal afterwards spring body both sides of stretching to, two free-end horizon distances equal 1 millimeter of the diameter of circular port in the spring body, and interior spring stretches into after the outer spring; Two free spring silks of two free-ends of interior spring and outer spring are arranged side by side each other, and the spring coil of outer spring has more 1 circle than the spring coil of interior spring.The rail chair form is oval, and maximum inner diameter length is 3 millimeters, and the shortest interior path length is 1.5 millimeters; Thick is 1 millimeter, in the oval front of rail chair two perforation is arranged, and is respectively trapezoid rail hole and circular rail point hole; The length of side is 0.35 millimeter on the trapezoid rail hole, 0.9 millimeter of the following length of side, and height is 0.7 millimeter.Circular rail point bore dia is 0.5 millimeter.The area in trapezoidal rail hole is greater than the area in circular rail point hole.The rail filament diameter is 0.45 millimeter a high-elastic steel wire, and length is 25 millimeters, and the rail silk is 2.Spring merged in the spring body circular hole of afterwards interior spring with outer spring in 2 rail silks inserted simultaneously; Circular hole in the spring body of spring in the rail silk crosses; The one-sided free-end of every rail silk inserts in the trapezoidal rail hole of rail chair with the free-end of interior spring, outer spring respectively jointly; The other end of every rail silk is then stretched in the injection point hole, and two free-ends weld fixing in the rail hole.Interior spring, outer spring and rail silk all are to form with high-elastic steel wire manufacturing, and the rail silk also can be manufactured with high-elastic twisted wire and form, and rail chair then is to manufacture with medical metal to form.

Specific embodiments:

At first clean the corona face, then cheeks band or single cheek side pipe band are fixed on the corona.Draw back track elastic force spring according to the size in a gap of grinding one's teeth in sleep, the distance of drawing back is larger than actual distance, the free-end of rail silk is burnt salmon pink insert the cheek side pipe after cooling on alcohol burner, can the closing gap use with the rail silk back bending after the annealing.It should be noted that when using track elastic force spring and must strengthen the stable of anchorage, prevent anchorage loss.This spring uses when drawing back the back for closing gap, and that does not draw back then is used for opening clearance through adnexa increase resistance.Back bending afterburning use of annealing again again occur then stretching in tired in strength, then remove adnexa during opening clearance, moving to free-end increases new adnexa and accomplishes moving of tooth body.
