Yakhiwe nge-monomer ne-oligomer futhi iqukethe amaqembu asebenzayo asebenzayo.Ingaqalisa ukusabela kwe-polymerization ngesiqalisi sokukhanya ngaphansi kwemisebe ye-UV ukuze ikhiqize ifilimu engancibiliki.I-resin ephulukisiwe ekhanyayo, eyaziwa nangokuthi i-photosensitive resin, iyi-oligomer engabhekana noshintsho olusheshayo emzimbeni namakhemikhali ngesikhathi esifushane ngemuva kokukhanyiswa ukukhanya, bese i-crosslink futhi yelaphe.I-UV resin elaphekayo iwuhlobo lwe-photosensitive resin enesisindo esiphansi samangqamuzana.Inamaqembu asebenzayo angelapheka nge-UV, njengamabhondi amabili angagcwele noma amaqembu e-epoxy.I-resin yelapheka ye-UV iyinhlaka ye-matrix yezingubo ezilaphekayo ze-UV.Ihlanganiswe ne-photoinitiator, i-diluent esebenzayo kanye nezithasiselo ezihlukahlukene ukuze kwakhiwe i-UV eyelaphekayo.
I-resin eyelaphekayo ye-UV yakhiwe i-monomer ne-oligomer.Iqukethe amaqembu asebenzayo futhi ingaqalisa ukusabela kwe-polymerization ngesiqalisi sokukhanya ngaphansi kwemisebe ye-UV ukuze ikhiqize ifilimu engancibiliki.I-Bisphenol I-epoxy acrylate inezici zejubane lokuphulukisa ngokushesha, ukumelana okuhle kwe-solvent yamakhemikhali kanye nobulukhuni obuphezulu.I-polyurethane acrylate inezici zokuguquguquka okuhle nokumelana nokugqoka.I-resin ehlanganisiwe ephulukisiwe iyinto evame ukusetshenziswa yokugcwalisa nokulungisa eMnyangweni Wezifo Zesisu.Ngenxa yombala wayo omuhle namandla athile acindezelayo, idlala indima ebalulekile ekusetshenzisweni komtholampilo.Sithole imiphumela egculisayo ekulungiseni amaphutha ahlukahlukene kanye nezimbotshana zamazinyo angaphambili.
Ukuqhathaniswa kokwelashwa ngomlomo
Kuma-caries ajulile endaweni enkulu, izindlela eziningi zokubuyisela zendabuko zinezinzuzo zazo kanye nokubi: i-amalgam inobulukhuni obuphezulu nokumelana nokucindezela okuqinile, kodwa ayinakunamathela (ayinandlela-mbili), incike kuphela ekushumekeni ngomshini, inokukhasa, futhi ukugqwala okuthile nobuthi.Ukuhlaziywa kwezinto ezincibilikisiwe kubonisa ukuthi iMercury, isiliva, ithusi ne-zinc ziyancibilika [2];Usimende we-ionomer wengilazi unokunamathela okuhle, kodwa unobunzima obumpofu, awukwazi ukumelana nokugqoka futhi kulula ukushintsha umbala;I-inlay (kufaka phakathi i-alloy, ipulasitiki kanye ne-porcelain) ukubuyiselwa, ukubuyisela okuyisisekelo komqhele womqhele, umqhele wegobolondo lensimbi kanye ne-porcelain ehlanganiswe nokubuyisela umqhele wensimbi kusetshenziswa kabanzi emisebenzini yomtholampilo, kodwa ukulungiswa kwamazinyo kunokuguga okukhulu, inqubo eyinkimbinkimbi kanye nezindleko eziphezulu.
I-resin ehlanganisiwe ye-UV isetshenziswa kabanzi emtholampilo.Inokusebenza okuhle, umbala omuhle futhi ohlala njalo, ukusebenza okulula, izindleko eziphansi futhi zithandwa kakhulu.Kodwa i-photosensitive resin ine-phototropism.Indlela yokugcwalisa eqondile emlonyeni iyamukelwa, futhi umthombo wokukhanya uvela ohlangothini olulodwa, okubophezelekile ukuthi ubangele ukuthi i-resin polymerization phansi kanye nodonga lomhume alulungile njengendawo engaphezulu, okuholela ekuqhekekeni lapho kuhlangana khona. amazinyo angaphansi [3].Ezinye izifundo zibonise ukuthi izinga lokuphulukisa le-resin eyinhlanganisela ngemva kokwelashwa okukhanyayo lingama-43% ~ 64%[3].Eqinisweni, izigcwalisi ezinjalo zidlala kuphela i-1/2 ~ 2/3 yezakhiwo zazo ezibonakalayo.Ukuze kuxazululwe le nkinga, ukugcwaliswa kwezingqimba (2 mm kungqimba ngalunye) kuvame ukusetshenziselwa ukwelapha ukukhanya emtholampilo, kodwa ungqimba ngalunye lwale ndlela luvezwa endaweni enomswakama emgodini womlomo, ngakho-ke kunenqwaba ye-n- 1 "izendlalelo" ekugcwaliseni okuyizendlalelo ezilodwa.Manje isetshenziswa kabanzi kuma-coatings kanye noyinki.
