Iqulunqwe yi-monomer kunye ne-oligomer kwaye iqulethe amaqela asebenzayo asebenzayo.Inokuqalisa ukusabela kwepolymerization ngokuqalisa ukukhanya phantsi kweradiation ye-UV ukuvelisa ifilimu enganyibilikiyo.I-resin ephilisiweyo yokukhanya, ekwabizwa ngokuba yi-photosensitive resin, yi-oligomer enokuthi yenzeke ngokukhawuleza utshintsho lomzimba kunye neekhemikhali ngexesha elifutshane emva kokutshiswa kukukhanya, kwaye emva koko i-crosslink kunye nokunyanga.I-resin enyangekayo ye-UV luhlobo lwe-photosensitive resin enobunzima obuphantsi bemolekyuli.Inamaqela asebenzayo anokuthi anyangeke yi-UV, njenge-unsaturated double bonds okanye amaqela e-epoxy.I-resin enyangekayo ye-UV yintlaka ye-matrix yeengubo ezinyangekayo ze-UV.Idityaniswe ne-photoinitiator, i-diluent esebenzayo kunye nezongezo ezahlukeneyo ukwenza iingubo ezinyangekayo ze-UV.
I-resin enyangekayo ye-UV yenziwe nge-monomer kunye ne-oligomer.Iqulethe amaqela asebenzayo kwaye inokuqalisa i-polymerization reaction by light initiator phantsi kwe-UV irradiation ukuvelisa ifilimu enganyibilikiyo.I-Bisphenol I-epoxy acrylate ineempawu zesantya sokunyanga ngokukhawuleza, ukuxhathisa okulungileyo kwikhemikhali ye-solvent kunye nobunzima obuphezulu.I-polyurethane acrylate ineempawu zokuguquguquka okulungileyo kunye nokuxhatshazwa kokugqoka.I-resin ehlanganisiweyo ephiliswayo yinto eqhelekileyo esetyenziswayo yokuzalisa kunye nokulungisa izinto kwiSebe le-Stomatology.Ngenxa yombala wayo omhle kunye namandla athile oxinzelelo, idlala indima ebalulekileyo kwisicelo seklinikhi.Siye safumana iziphumo ezanelisayo ekulungiseni iziphene ezahlukeneyo kunye nemingxuma yamazinyo angaphambili.
Ukuthelekiswa konyango lomlomo
Kwiindawo ezinzulu zecaries, iindlela ezininzi zokubuyisela ngokwemveli zineengenelo kunye nezingeloncedo zazo: i-amalgam inobulukhuni obuphezulu kunye nokumelana noxinzelelo oluqinileyo, kodwa ayinakuncamathela (akukho ndlela-mbini yokutsalwa), ixhomekeke kuphela kumatshini wokuzinzisa, inobuchwephesha, kwaye iye yancamathela. ukudleka okuthile kunye netyhefu.Uhlalutyo lwezinto ezinyibilikisiweyo lubonisa ukuba iMercury, isilivere, ithusi kunye ne-zinc zinyibilikile [2];I-samente ye-ionomer yeglasi inokubambelela kakuhle, kodwa inobunzima obunzima, ayigugi kwaye kulula ukuyitshintsha umbala;I-Inlay (kubandakanya i-alloy, iplastiki kunye ne-porcelain) ukubuyisela, ukulungiswa kwesiseko sesithsaba sokubuyisela, isithsaba seqokobhe lesinyithi kunye ne-porcelain edityaniswe kwintsimbi yokubuyisela isithsaba zisetyenziswa ngokubanzi kwiklinikhi, kodwa ukulungiswa kwezinyo kunokugqoka okukhulu, inkqubo enzima kunye neendleko eziphezulu.
I-resin ehlanganisiweyo ye-UV enyangekayo isetyenziswa kakhulu eklinikhi.Inokusebenza kakuhle, umbala omhle kunye ongapheliyo, ukusebenza okulula, ixabiso eliphantsi kwaye lithandwa kakhulu.Kodwa i-photosensitive resin ine-phototropism.Indlela yokuzalisa ngokuthe ngqo emlonyeni iyamkelwa, kwaye umthombo wokukhanya uvela kwicala elinye, elibophelelekile ukuba libangele ukuba i-polymerization ye-resin ezantsi kunye nodonga lomqolomba alulunganga njengomphezulu, okubangela ukuqhekeka kwi-junction. amazinyo asezantsi [3].Olunye uphando lubonise ukuba iqondo lokunyanga le-resin edibeneyo emva kokunyanga ukukhanya yi-43% ~ 64% [3].Enyanisweni, ezo zigcwalisi zidlala kuphela i-1/2 ~ 2/3 yezinto zabo eziphathekayo.Ukuze kusonjululwe le ngxaki, umaleko ukugcwaliswa (2 mm umaleko ngamnye) ngokuqhelekileyo isetyenziselwa ukunyanga ukukhanya eklinikhi, kodwa umaleko ngamnye le ndlela evezwe kwindawo efumileyo kumqolo womlomo, ngoko kukho isitakhi n- I-1 "iileya" ekuzaliseni eziziingqimba enye.Ngoku isetyenziswa ngokubanzi kwiingubo kunye neenki.
