4mol umgubo weZirconia

Ukubunjwa kunye neSakhiwo I-4mol zirconia luhlobo lwe-zirconia ceramic eyenziwe nge-4 mol% yttria-zirconia ezinzile. I-Zirconia luhlobo lwe-ceramic eyenziwe yi-element zirconium kunye ne-oxygen. Yimathiriyeli emhlophe, eyikristale eqine kakhulu kwaye ixinene. Xa i-zirconia izinzile kunye ne-yttria, iba yinto exhathisayo ekuqhekekeni kunye ne-fracturing. Iiyoni ze-yttria zifakwe kwi-zirconia crystal structure, eyenza intsimi yoxinzelelo enceda ukukhusela ukuqhekeka ekusasazeni. Oku kwenza i-zirconia ibe yinto ebalaseleyo yokubuyisela amazinyo, aphantsi koxinzelelo oluninzi kunye noxinzelelo.

Iipropati Zomzimba

Iimpawu ezibonakalayo ze-4mol zirconia zizinto ezenza kube yinto efanelekileyo kakhulu yokubuyisela amazinyo. Inoxinaniso oluphezulu, okuthetha ukuba yomelele kakhulu kwaye iyakwazi ukumelana namandla amaninzi. Kwakhona ine-conductivity ephezulu ye-thermal, oku kuthetha ukuba inokukhupha ukushisa ngokukhawuleza nangokufanelekileyo. Xa kuthelekiswa nezinye izixhobo zamazinyo, i-zirconia inamandla aphezulu okuguquguquka kunye nokuqina okuphezulu kokuphuka. Oku kuthetha ukuba akunakwenzeka ukuqhekeka okanye ukuphuka phantsi koxinzelelo. Kwakhona ine-coefficient ephantsi yokwandiswa kwe-thermal, oku kuthetha ukuba akunakwenzeka ukuba kwandiswe okanye kukhontrakthi ekuphenduleni utshintsho kwiqondo lokushisa. Le yipropati ebalulekileyo yokubuyiselwa kwamazinyo, efuna ukulingana ngokufanelekileyo nangokukhuselekileyo emlonyeni.

Iipropati zoomatshini

Ukongeza kwiimpawu zayo zomzimba, i-4mol zirconia nayo ineempawu ezintle kakhulu zoomatshini. Inamandla aphezulu okuguquguquka, okuthetha ukuba inokumelana nokugoba okuninzi kunye nokujika ngaphandle kokuphuka. Kananjalo inokuqina okuphezulu kokuqhekeka, okuthetha ukuba inokumelana nokuqhekeka kunye nokuqhekeka. Xa kuthelekiswa nezinye izixhobo zamazinyo, i-zirconia inamandla aphezulu okuguquguquka kunye nokuqina okuphezulu kokuphuka. Oku kuyenza ibe yimathiriyeli ebalaseleyo yokubuyiselwa kwamazinyo, ekufuneka ikwazi ukumelana noxinzelelo oluninzi kunye noxinzelelo. Kananjalo akukho lula ukuba iguge okanye yonakale ngokuhamba kwexesha, nto leyo ethetha ukuba inokuhlala iminyaka emininzi.

IiPropathi zokubona

Enye yeenzuzo ze-4mol zirconia yimpawu zayo ezibonakalayo. Inomlinganiselo ophezulu wokuguquguquka, oku kuthetha ukuba ivumela ukukhanya ukuba kudlule kuyo kwaye kubonakalise kwisakhiwo sezinyo esingaphantsi. Oku kuyinika inkangeleko yendalo efana namazinyo endalo. i-zirconia nayo ifumaneka kuluhlu lwee-shades kunye nemibala, evumela ukuba ihambelane nombala wamazinyo ajikelezileyo. Oku kuyenza ibe yimathiriyeli ebalaseleyo yokubuyiselwa kwamazinyo, ekufuneka isebenze kwaye ithandeke ngobuhle.

Biocompatibility

Enye yezona zinto zibaluleke kakhulu kuyo nayiphi na into yamazinyo kukuhambelana kwayo kwezinto eziphilayo. Oku kubhekisa kwindlela izinto ezisebenzisana ngayo nomzimba nokuba zibangela naziphi na iziphumo ezibi okanye iingxaki zempilo. Ngethamsanqa, i-zirconia i-biocompatible kakhulu kwaye ivavanywe ngokubanzi ukuba isetyenziswe ekubuyiselweni kwamazinyo. Ayinatyhefu kwaye ayibangeli nakuphi na ukusabela okanye iingxaki zempilo. Oku kuyenza ibe sisixhobo esikhuselekileyo nesisebenzayo sokubuyisela amazinyo.

Umkhwa wexesha elizayo we-zirconia

Ukujonga phambili, ukusetyenziswa kwexesha elizayo kwe-4mol zirconia kwi-dentistry kubonakala kuthembisa. Abaphandi baphonononga iindlela ezintsha zokuphucula iipropathi zezinto kunye nokwandisa uluhlu lwayo lwezicelo. Ngokomzekelo, kukho uphando oluqhubekayo malunga nokusetyenziswa kwe-zirconia kwizifakelo zamazinyo, ezinokunika enye into ehlala ixesha elide kunye ne-biocompatible kwizinto zokufakelwa kwendabuko. Kwakhona kunomdla wokusebenzisa i-zirconia kwizixhobo ze-orthodontic, ezifana nezibiki kunye neengcingo, ukuphucula amandla abo kunye nokuqina. Ukuqhubela phambili kweendlela zokuvelisa, ezifana nemveliso yokongeza kunye noyilo oluncediswa yikhompyutheni, kwakhona kwenza kube lula ukuvelisa ukubuyisela okunzima kwamazinyo usebenzisa i-zirconia. Oku kunokukhokelela ekubuyiseleni amazinyo okulungiselelwe ngakumbi kunye nokuchanekileyo afaneleka ngcono kwiimfuno ezizodwa zesigulane ngasinye. Ngokubanzi, ikamva libukeka liqaqambile kwi-4mol zirconia kwi-dentistry. Njengoko uphando kunye nophuhliso luqhubeka, sinokulindela ukubona usetyenziso olutsha noluchulumancisayo lwesi sixhobo sisebenza ngeendlela ezininzi kwiminyaka ezayo. Isiphelo Ekugqibeleni, i-4mol zirconia luhlobo lwe-zirconia ceramic oluye lwafumana ukuthandwa kwiminyaka yamuva ngenxa yeempawu zayo ezintle. Yinto eyomeleleyo, ehlala ixesha elide ekwaziyo ukumelana noxinzelelo oluninzi kunye noxinzelelo. Ikwanayo nenkangeleko ebukekayo yendalo eyenza ibe yinto ebalaseleyo yokubuyisela amazinyo. I-biocompatibility yayo kunye nokhuseleko lwenza ukuba lube lukhetho oludumileyo koogqirha bamazinyo kunye nezigulana ngokufanayo. Ukuba ufuna ukubuyiselwa kwamazinyo, thetha nogqirha wakho wamazinyo malunga nokuba i-4mol zirconia inokuba lolona khetho lufanelekileyo kuwe.
