And a kind of polyparaphenylene's benzodiazole (pbo) fibre reinforced composites for gear division periodontal band and preparation method thereof.
Background technology
Periodontal disease is the frequently-occurring disease in oral cavity, is higher than dental caries in the prevalence of China's periodontal disease.Periodontal disease is periodontal tissue
Chronic progressive external destructive disease, one of its main clinic symptoms be tooth loosen.By periodontal band by agomphiasis and
Healthy tooth link is fixed together, and forms new chewing unit, to disperse gmatjpdumamicss, mitigates the load of periodontal tissue, makes to suffer from tooth
Obtain physiological rest, be that ruinate periodontal tissue wound healing creates favorable conditions, be allowed to exercise normal occlusion work(
Energy.
The material being presently available for loose tooth fixation is more, but equal Shortcomings: stainless steel silk joint composite resin band:
Aesthetic property is poor, needs to carry out tooth preparation, but the mechanical performance of tinsel and stir-in resin is poor, and both materials are unable to shape
Become chemical bond, often produce shearing force between interface, stress concentration occurs, lead to composite resin part even to completely fall off,
Ligature ruptures, and tooth loosens again, leads to Endodontic failure；Photosensitive resin binds band: although easy to operate, aesthetic property is good,
But fixing intensity is weaker, it is suitable only for and fixes temporarily；Fibrous band contracture: chemical bond can be produced with resin, have preferable aesthetic property
With biocompatibility, but the mechanical property such as existing fiber bending intensity, the modulus of elasticity in static bending, toughness is still not enough, for occlusion
