Description
Technical field
The present invention relates to a kind of nano-composite resin material, more particularly to a kind of gear division are interim with Nano filling compound resin
It is preced with bridge material and preparation method thereof.
Background technology
Resin starts to introduce dentistry in 20 middle of century.It has easy to operate, good colour, price more low
Advantage.But mechanical performance is poor, so being used only for making basal seat area, artificial tooth, provisional dummy etc., decades earliest
To be continued to develop with the research to resin material, its mechanical performance improved a lot more in the past, and application also constantly expands
Greatly.Especially the progress of resin material is even more to obtain many breakthroughs to foot in recent years, and be used to fix reparation field.Resin material
Much progress is a kind of new composite that the sixties, Bowen was proposed.It regard Bis-GMA as resinous substrates.And make silicon
Occur chemically to be connected for filler grain and matrix.Thus greatly improve mechanical performance.Many research surfaces, it is different big
Small, shape filler grain, and whole mechanical performance of their contents in resin to resin material have very big shadow
Ring.Since nineteen ninety-five, many companies all release the Guan Qiao resins of a new generation, have flying for matter in the internal structure of material
The distribution that jump, its internal platform have polyfunctional crosslinking agent and filler grain is also worthy of careful study greatly, compared with originally only containing double function key point
The conventional resins of son, their formula is complex, in addition to having traditional function key molecule, also containing 4~6 function key molecules
Group.This molecular structure is crosslinked there is provided more double bonds, can not only form more cross-linked networks, moreover it is possible to preferably control
The position interlinked on carbon molecules chain a little.These factors both contribute to improve wearability, elasticity, bending strength of resinous substrates etc..
Provisional crowns and bridges（provisional fixed restoration）In being dentistry fixed denture repairing and treating
An important part.Dentistry provisional prosthesis refers to patient from after initial abutment preparation to wearing final dummy
What is used in whole transition period has the fixed or movable artificial tooth of stable and function attractive in appearance.Patient is required in the process
Wear provisional prosthesis.One good provisional prosthesis, first has to ensure the health of wearer, except service life and color
The aspect of fidelity two is outer, and the requirement and final dummy to provisional prosthesis are substantially the same, it is necessary to meet many phases
Close and require.Scholars using Vahidi as representative formulated provisional prosthesis need meet multiple requirements, including it is attractive in appearance,
Comfortably, pronunciation, function, periodontal health, maxillary mandibular relation and to the diagnostic reparation of denture designing in terms of.
Duplex transportation Provisional restorative materials are because with numerous excellent performances, being widely applied to the numerous of dentistry and having controlled
Treatment field.They widely used, such as crowns and bridges, implant prostheses, it is also possible to make veneer, inlay, onlay, viscous
The many dentistry manufacturers of scaffolding ... have also been poured into substantial amounts of research fund, constantly release new generation product.
The Nano filling composite resin material that the present invention is provided, it is interim to repair in the preparation for clinically crown and bridge
