Njengengxenye ebalulekile embonini yezokwakha, ukuxhuma okugcwele kudlala indima ebalulekile.Eminyakeni engamashumi amahlanu edlule, izinsimbi bezisetshenziswa kakhulu embonini yezokwakha kanye nezinye izinto zokusebenza zemishini.Ngenxa yokuthuthukiswa okujwayelekile kokusebenza kahle namandla ezinto zokwakha, isisindo somzimba wezakhiwo sikhula ngendlela elula, futhi isilinganiso samandla nesisindo sezinto ezihlangene nazo ziyakhula.Isakhiwo esilula kakhulu asiyona into enhle, ukumelana kwaso nomoya kanye nomthelela kuba buthaka kancane kancane, ngakho-ke kuba nengozi yokuphepha lapho sisebenzisa lezi zakhiwo.Esikhathini esidlule, abanye abantu babecabanga ukuthi isakhiwo singakhiwa kuphela ngokuthembela esisindweni sesakhiwo ngokwaso kanye nokunamathela kodaka, kodwa lokhu akunjalo, noma yisiphi isakhiwo asikhiwanga ngodaka kuphela, kulokhu konke Mechanical. izinsimbi ezifana nezinkinobho zidlala indima yazo.Ukuze wenze ukukhubazeka kwesakhiwo okubangelwa ukunciphisa isisindo.Njengoba isisindo sezingxenye zokwakha siba lula, ivolumu yabo nayo iyancishiswa, ukuze indawo lapho intambo egcwele ifakwe khona iyancipha ngokufanayo.Kungenxa yalesi sizathu ukuthi amandla entambo egcwele iyadingeka ukuba ande, nokusebenza kwayo Kumele kubikezelwe ngokuphelele, ukuze kuqinisekiswe ukuphepha kwesakhiwo, futhi kuthuthukise ukumelana komoya kanye nokumelana nomthelela wesakhiwo.Ungawubukeli phansi umthelela wokulutha okugcwele, ngezinye izikhathi okudlala indima enkulu.
Amahange alezi zinhlobo ezilandelayo:
(1) Ibhawodi yehange yokwandisa
Amabhawodi okunweba ihange, abizwa ngokuthi amabhawodi okunweba, sebenzisa ukunyakaza okuhlobene kwekhoni kanye neshidi lokunweba (noma umkhono wokunweba) ukuze kuthuthukiswe ukunwetshwa kweshidi lokunweba, kukhiqize amandla okunweba nawokunweba ngokhonkolo odongeni lwembobo, futhi kukhiqize amandla okunweba nawokunweba ngokhonkolo odongeni lwembobo. ukumelana nokukhipha nge-shear friction.Ingxenye eqaphela ukubambelela kwesiqephu esixhunyiwe.Amabhawodi okunweba ihange ahlukaniswe ngohlobo lokulawula i-torque kanye nohlobo lokulawula ukufuduka ngokuya ngezindlela ezihlukene zokulawula amandla okunweba ngesikhathi sokufakwa.Eyokuqala ilawulwa yi-torque, kanti eyesibili ilawulwa ngokususwa.
(2) Ibhawodi yehange yohlobo lokuphindayo
Amahange ohlobo oluvuzayo, abizwa ngokuthi ama-reaming bolt noma ama-grooving bolt, aphinde agxumeke futhi aphinde amise ukhonkolo ngaphansi kwembobo ebhoboliwe, kusetshenziswa ukuxhuma okuwumshini phakathi kwendawo ephethe ukhonkolo eyakhiwe ngemva kokuvuselelwa kabusha kanye nenhloko yokunweba yebhawodi lehange. ., ingxenye eqaphela ukubambelela kwesiqephu esixhunyiwe.Ama-reaming ama-anchor bolts ahlukaniswe abe-pre-reaming kanye nokuzivuselela ngokwawo ngezindlela ezihlukene zokuphinda zenziwe kabusha.Eyangaphambili i-pre-grooving futhi ivuselela ngethuluzi elikhethekile lokumba;umshudo wokugcina wehange ufika nethuluzi, elizikhukhumeza ngokwalo futhi lizibuyisela kabusha ngesikhathi sokufakwa, futhi ukugoba nokufakwa kuqedwa ngesikhathi esisodwa.
(3) Amabhawodi okusetshenzwa kulengwa aboshwe
Amabhawodi okusetshenzwa kwe-anchor ahlanganisiwe, aziwa nangokuthi amabhowudi okuqinisa amakhemikhali, abizwa ngokuthi amabhawudi amakhemikhali noma amabhowuthi okuqinisa, enziwe ngezinamatheliso zamakhemikhali ezikhethekile (iglue okunamathiselwe kwi-anchoring) ukuze kunamathiselwe futhi kulungiswe izikulufu namapayipi anentambo yangaphakathi emigodini yokubhoboza yama-substrates kakhonkolo.Umsebenzi wokuhlanganisa nokukhiya phakathi kwe-adhesive ne-screw kanye ne-adhesive kanye nodonga lwembobo kakhonkolo ukuze kubonakale ingxenye ehlanganiswe nesiqephu esixhunyiwe.
(4) Ukutshalwa kwemisipha ngamakhemikhali
Ibha yokutshala yamakhemikhali ihlanganisa ibha yensimbi enentambo kanye nenduku ende yesikulufu, okuwubuchwepheshe bokuxhuma ngemuva kwehange obusetshenziswa kakhulu emibuthanweni yobunjiniyela yezwe lami.Ukubambelela kwezinsimbi zokutshala amakhemikhali kuyafana nokuhlanganisa amabhawodi okunamathisela ihange, kodwa ngenxa yokuthi ubude bezinsimbi zokutshala amakhemikhali nezikulufu ezinde abunqunyelwe, bufana nokubambelela kwezinsimbi zikakhonkolo ezifakwe endaweni, kanye nefomu lomonakalo. kulula ukuyilawula, futhi ngokuvamile ingalawulwa njengokulimala kwezinsimbi zokusethula.Ngakho-ke, ilungele ukuxhunywa okuqinile kwamalungu esakhiwo noma amalungu angewona wesakhiwo ukuqina kwawo okuqinile nokuzamazama komhlaba kungaphansi noma okulingana no-8.
(5) Izikulufu zikakhonkolo
Isakhiwo kanye nendlela yokunamathisela yezikulufo zikakhonkolo zifana nezikulufu zokhuni.Inqubo ekhethekile isetshenziselwa ukugoqa nokucisha isikulufu sentambo esiqinile nesibukhali sommese.Ngesikhathi sokufakwa, imbobo eqondile ene-diameter encane i-pre-drilled, bese i-screw ifakwe ngaphakathi, kusetshenziswa intambo nembobo.Isenzo se-occlusal phakathi kokhonkolo odongeni sikhiqiza amandla okudonsa futhi sibona ingxenye ebambelele ezingxenyeni ezixhunyiwe.
(6) Ukudubula izinzipho
Izipikili zokudubula uhlobo lwezinzipho zensimbi ezinokuqina okuphezulu, okuhlanganisa izikulufu, ezishayelwa isibhamu, zibe ukhonkolo, futhi zisebenzisa izinga lokushisa eliphezulu (900 ° C) ukuze zenze izipikili zensimbi nokhonkolo kuhlanganiswe ngenxa yokuhlangana kwamakhemikhali nokubopha.Qaphela ukubambelela kwezingxenye ezixhunyiwe.
