The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, this utility model is further elaborated.Specific embodiment described herein is only in order to explaining this utility model, and is not used in restriction this utility model.
As shown in Figure 1 and Figure 2, the orthodontic retainer 1 that the of the present utility model and body biomechanics compatibility is good is the rounded or oval-shaped circle silk in cross section or the rectangular flat filament in cross section, wherein the cross-sectional diameter of circle silk is 0.010～0.022 inch, the transversal face length of flat filament is 0.010～0.018 inch, and wide is 0.025～0.032 inch.As shown in Figure 3, orthodontic retainer 1 in use, the doctor can bend orthodontic retainer circular arc or the depression that adapts for the tongue side curvature variation with denture by finger tip or instrument, it is continuous U-shaped, in order to fully fitted in the tongue side of orthodontic retainer patient denture, the convenient follow-up cementation that carries out.For orthodontic retainer 1 being convenient to be bonded in the tongue side of denture, the surface of orthodontic retainer 1 is handled by acid etching and/or sandblast etc. and is formed rough surface.
Exist rigidity to cross strong and the not good enough shortcoming of plastic type for the stainless steel material orthodontic retainer that generally uses, this utility model uses NiTi base alloy to make orthodontic retainer.NiTi base alloy is the class in the alloy, the NiTi based multicomponent alloy that NiTi base alloy comprises the NiTi bianry alloy and added other constituent elements.Its expansion and contraction reaches 107 times more than 20% fatigue life, and its corrosion resistance is better than best medical stainless steel at present.Aspect mechanical characteristic, stainless steel material and tissue biomechanical compatibility are poor, and compliance is very limited, and strain rate and increases or reduces along with the effect of external force obviously is linear about 1%.
By contrast, tissue such as skeleton, tendon etc. can reach about 10% strain rate, and its strain rate and external force are non-linear relation, after causing that the external force disappearance of deformation takes place, its deformation energy is restored by very little stress, and the tissue ring that load/non-load curve surrounds has tangible hysteresis quality.Because NiTi base alloy also has the mechanical characteristic similar to tissue, so the biomechanical compatibility that the NiTi base closes is better than rustless steel.Because orthodontic retainer directly is bonded on the tongue side of just abnormal patient's denture, along with just abnormal patient chews, speech etc. can often produce deformation, so the better NiTi base of biomechanical compatibility alloy obviously is more suitable for making the mucosity type orthodontic retainer than rustless steel.
NiTi base alloy exists two kinds of different crystal structure phases, i.e. Ovshinsky bulk phase and martensitic phases under the temperature change situation.Phase transformation during the cooling of NiTi base alloy is Ovshinsky bulk phase-R phase-martensitic phase in proper order, and wherein R is that Pedicellus et Pericarpium Trapae is square mutually; Austenite is the state of temperature when higher (be higher than Af: i.e. the temperature that begins of austenite), is cube, and hard, shape is more stable; State when martensitic phase is temperature relatively low (be lower than Mf: i.e. the temperature that finishes of martensite) is hexagon, is ductile, and repeatability, instability, more yielding.This utility model utilized that martensite NiTi base alloy plastic type is good, rigidity is low, can bend repeatedly and characteristics such as easy fracture not, it is applied in the making of orthodontic retainer, and makes the NiTi base alloy silk of this orthodontic retainer in the human oral cavity environment, be in the martensitic phase state all the time.
Should be pointed out that the above specific embodiment can make those skilled in the art more fully understand this utility model, but limit this utility model never in any form.Therefore; although this description has been described in detail this utility model with reference to drawings and Examples; but; those skilled in the art are to be understood that; still can make amendment or be equal to replacement this utility model; in a word, all do not break away from technical scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the middle of the protection domain of this utility model patent.
