Isithando Sokuthungela Amazinyo vs. Isithando Sokuthungela iPorcelain: Isikhokelo Esipheleleyo Sezixhobo, Inkqubo, kunye Nokuthenga Efanelekileyo

Ngamazwi alula: amandla xa kuthelekiswa nobuhle . Isithando somlilo esitshisayo siyenza iqine i-zirconia ibe yindlela yokubuyisela esebenzisekayo. Isithando somlilo se-porcelain siyenza ibonakale ngathi lizinyo lokwenyani. Amaqondo obushushu ahlukeneyo, iindlela ezahlukeneyo zokusebenza, imisebenzi eyahlukeneyo - kwaye akukho namnye onokwenza umsebenzi womnye.

Esi sikhokelo sichaza ngqo into eyenziwa ngumatshini ngamnye, isizathu sokuba zingenakutshintshwa, kunye nendlela yokugqiba ukuba zeziphi (okanye zidityaniswe) ezifunekayo kwilabhoratri yakho. Ekugqibeleni, uya kwazi ukuba zeziphi iiyunithi ezilawula amandla olwakhiwo kunye nokuba zeziphi ezilawula umbala kunye nokukhanya, indlela yokwenza uhlahlo lwabiwo-mali ngokusekelwe ekubeni ilabhoratri yakho isebenzisa ikakhulu izithsaba ze-zirconia kunye neebhulorho okanye ikakhulu ii-veneers kunye nee-ceramics ezifakwe ileya, kunye nokuba zeziphi iimpawu ezibalulekileyo xa uthelekisa ii-oven - ngaphaya kobushushu obuphezulu kwiphepha le-spec.

Kutheni iiLabhoratri zamazinyo zifuna zombini iintlobo zesithando somlilo

I-zirconia coping esandula ukuvela kumatshini wokusila isathambile kwaye inetshokhwe — ungayiqhekeza phakathi ngeminwe yakho. Iba yindlela yokubuyisela esebenzisekayo emva kokutshisa ngaphezu kwe-1,400°C, inkqubo ebizwa ngokuba yi-sintering, umsebenzi wesithando sokutshisa i-zirconia. Ukwenza olo lungiso lubukeke njengezinyo lendalo — umbala ofanelekileyo, ukukhanya okufanelekileyo — kuthatha elinye inyathelo: ukubeka i-porcelain, ukudaya, kunye nokugquma kwisithando sokutshisa i-porcelain, esihlala sisebenza phakathi kwe-700–1,000°C.

Omnye umatshini uphendula athi "ingaba iza kuhlala ixesha elide?" Omnye uphendula athi "ingaba ibonakala ilungile?" Loo mibuzo mibini ikwimigangatho yobushushu eyahlukileyo ngokupheleleyo kwaye ifuna izixhobo ezahlukeneyo ngokupheleleyo. Yiyo loo nto ungasoze ubone uluhlu lwezixhobo zelebhu yamazinyo ezijonga ezi zinto njengezinokutshintshwa.

Yintoni iZirconia Sintering Furnace kwaye isebenza njani?

Isithando somlilo esitshisa i-zirconia sinomsebenzi omnye: ukudibanisa amasuntswana e-zirconia kunye phantsi kobushushu obuphezulu obuhlala ixesha elide ukuze ii-micro-pores zangaphakathi zinyamalale kwaye izinto zinciphe ukusuka kwimeko yokuba neembobo ziye kuxinano olupheleleyo. Loo nkqubo - uxinano - yindlela ekuphela kwayo i-zirconia efumana ngayo amandla ayo okugqibela, ukukhanya, kunye nokuchaneka kobukhulu. Yitsibe, kwaye into oyigayileyo isengumgubo we-ceramic othambileyo ongenamsebenzi wokungena emlonyeni wesigulana.

Nantsi indlela esebenza ngayo le nkqubo: ingcali isusa imo yokulungisa kwibhloko ye-zirconia efakwe ngaphambili ("eluhlaza" okanye "emhlophe"), ethambileyo kwaye kulula ukuyisika kweli nqanaba. Uyilo lwenziwa lube lukhulu ngama-20-25% ukuze kujongwe ukuncitshiswa ngexesha lokudubula. Inxalenye egayiweyo emva koko ingena kwisithando somlilo esitshisayo, apho ilandela igophe elicetyiswayo ngumenzi lokufudumeza, ukubamba, kunye nokupholisa, incipha ukuya kubukhulu bayo bokugqibela ngelixa incipha ngaxeshanye. Inyathelo ngalinye kuloo khonkco lidibene - nokuba ukuphambuka okuncinci kwigophe lokusitshisa kubonakala kamva njengengxaki yokulingana emlonyeni wesigulana.

Eyona ndawo ixhaphakileyo yokusilela ayikokuba ubushushu obuphezulu alwanelanga — kukufana kobushushu ngaphakathi kwigumbi, okubonakala njengokungangqinelani komthunzi ngaphakathi kweqela elifanayo, okanye uxinzelelo lwangaphakathi kunye nokugoba kwizakhelo zebhulorho ezinkulu ezifudumeza ngokungalinganiyo. Le yingxaki kanye le Dentex Q7 eyakhelwe ukuyisombulula, isebenzisa ubuchwepheshe bayo be-ARCS (Automatic Rapid Compensation Sintering): inkqubo yokuphakamisa engenangcangcazelo elungisa ngokuzenzekelayo umgama phakathi kwendawo yokusebenza kunye nodonga lwegumbi, ikunika ulawulo oluqinileyo malunga namazinga okufudumeza, ukubamba, kunye nokupholisa ukuze ukwazi ukunciphisa ixesha lomjikelo ngaphandle kokunciphisa uxinano okanye ukukhanya.

Lo ngumatshini osebenzayo kuyo nayiphi na into eyakhelwe kwi-zirconia substrate: ii-crowns ezi-single kunye nee-crowns ezipheleleyo, apho ukuhambelana kombala we-batch-to-batch kubaluleke kakhulu; ii-frameworks ze-bridge ezineeyunithi ezininzi, apho ubukhulu bodonga obungalinganiyo bufuna ukulingana kobushushu obuqinileyo ukuze kuthintelwe ukugoba; kunye nokulungiswa okuxhaswe yi-implant kunye nee-abutments ezenziwe ngokwezifiso, apho nokutshintsha okuncinci kwisantya sokuncitshiswa kunokuphazamisa ukulingana okuchanekileyo kwi-implant.

Yintoni esetyenziselwa isithando somlilo se-porcelain samazinyo?

Isithando somlilo esitshisayo singenza i-zirconia ibe nzima, kodwa asinakunika umthunzi kunye nokukhanya kwezinyo lendalo - yiloo ndawo yesithando somlilo se-porcelain. Umsebenzi waso ophambili ugubungela amanyathelo amathathu: ukubeka i-porcelain, apho ingcali iqokelela i-ceramic ecoliweyo kwiileya ezilandelelanayo phezu kwe-zirconia okanye i-substrate yesinyithi kwaye itshise nganye nganye; ukufaka idayi, apho idayi yolwelo ifakwa ukulungisa umthunzi wendawo; kunye nokugquma, apho ukudubula kokugqibela kuvelisa umphezulu ogudileyo, okhanyayo ofana ne-enamel yendalo. Izithando ze-porcelain zikwaphatha uluhlu olubanzi lwezinto kunokuba zisenza izithando zomlilo - i-feldspathic layering porcelain, umaleko we-porcelain kwi-PFM (porcelain-fused-to-metal) restorations, kunye nokugquma kunye nokugquma kwe-lithium disilicate kunye nezinye iiglasi-ceramics. Ngokwenyani, nantoni na efuna ukugqitywa kobuhle idlula kwisithando somlilo se-porcelain ngaxa lithile.

Umahluko omkhulu wezixhobo phakathi kwesithando seporcelain nesithando esitshisayo yinkqubo yokukhupha umoya. Ngaphandle kokukhupha umoya kwigumbi ngexesha lokudubula, umgubo weporcelain ubamba amaqamza omoya amancinci, kwaye loo maqamza asasaza ukukhanya - yiyo loo nto ukubuyiselwa okungafakwanga manzi kubonakala ngathi kufana namafu okanye kunetshokhwe endaweni yokukhanya. Oogqirha bamazinyo kunye nezigulana banokubona loo mbonakalo "ifileyo" ngeliso lenyama, yiyo loo nto ukudubula nge-vacuum kungengophuculo olukhethekileyo kwisithando seporcelain - yingxaki yetafile. Ngaphaya kwesithando, ukufana kobushushu kunye nokuchaneka kwenkqubo kubaluleke kakhulu: amanqanaba ambalwa okutshintsha kwigumbi anele ukuvelisa ukungafani kombala okubonakalayo ngaphakathi kwebhetshi enye, kwaye ijika lokufudumeza/lokupholisa elingacacanga lishiya isakhiwo sangaphakathi sekristale yeporcelain singalingani, esibonakala njengokukhanya okuthe tyaba kunye nokugqitywa komphezulu omdaka.

Isithando Somlilo Esishushu Xa Sithelekiswa Nesithando Somlilo Seporcelain: Umahluko Ophambili Ngokucacileyo

Nje ukuba uqonde ukuba umatshini ngamnye wenza ntoni ngokwenene, umahluko ulula:

Ngaba Isithando Somlilo Esinye Singathatha Indawo Yesinye?

Hayi — kwaye isizathu sinqumla macala omabini. Asikuko nje ukuba "kushushu ngokwaneleyo."

Uninzi lwee-oven ze-porcelain azikwazi ukufikelela kwi-1,400°C-plus range i-zirconia ekufuneka iqine. Kwaneyunithi engaqhelekanga ethi iyakwazi ayakhiwanga ngezinto zokugquma okanye zokufudumeza ezilinganiswe ngolo hlobo lomthwalo ohlala ixesha elide wobushushu obuphezulu - yityhale nzima kwaye uya kuyifinyeza ixesha lobomi besixhobo ngokukhawuleza. Yiya kwelinye icala kwaye ingxaki iyajika: i-oven evuthayo, nokuba ine-headroom yokushisa engaphezulu, ihlala ingenaso inkqubo ye-vacuum kwaye akukho nanye kwezi nkqubo zintle zokudubula i-porcelain ezifuna ukutshayelwa. Sebenzisa enye ukufaka i-porcelain kwaye mhlawumbi uya kugqibela unesiphumo esibi nesingathandekiyo - kunye nezinto ezichithwayo.
