Crown-oluxonxiweyo metal: iifoto, ncomo, ufakelo. Production izithsaba ezibengezelayo emazinyweni

Metal neengqukuva ezibe amazinyo kusekho ezithandwayo, njengoko akukho nto kodwa ikhuseleke ngokomelela busebenzisa abangazange yasungulwa. Iimveliso ezinjalo ukususela kumaxesha amandulo ookhokho bethu, yaye basaqhubekeka ukukhonza abantu ihlala lwabo. Nangona uhlobo izithsaba ayonto nomtsalane, kodwa ke ixabiso nomgangatho kunxibelelana yokwenene.

Yintoni le

Crown-wabumba inqaku ebuntsimbi yenziweyo ukusuka aluminium ezahlukeneyo titanium hromokobaltovogo metal, nickel-chromium, kunye noyilo yayo exonxiweyo ngokupheleleyo. Eyona ndawo iphambili Isicelo kwalo ezahlukeneyo ngezithsaba - amazinyo uhlobo amazinyo ukuhlafuna. Oku kungenxa zabo icandelo kubuhle amahlwempu.

Crown (metal) uthathwa inqaku ngqo-wabumba ngayo nangona umbala sisinyithi ezahlukeneyo, kodwa kakhulu ngokuqinileyo ehleli emlonyeni. izizithsaba ezifana - ukukhetha elisemagqabini amazinyo ixesha elide.

Izinto eziluncedo iimveliso unit-cast

Loo nto iye kwiqela lokulungileyo, ezizezi:

1. Esinzulu omelene isakhiwo izinyo.
2. Ukhuseleko (amazinyo musa waphule musa ninamathele).
3. imilo ezahlukeneyo yokwakheka zendalo.
4. A ixabiso elincinane kuthelekiswa nezinye koontanga.
5. Ayizi kuyilibala amazinyo eziphikisanayo.
6. Okumangalisayo iphinde mu- yokusebenza.

Izizathu ukuba ufake

Iingcali ukucebisa ukubeka izithsaba metal kuphela kwiimeko ezithile;

• wabatshabalalisa abo amazinyo banoxanduva ukuhlafuna;
• icandelo kwemihlathi ye inani kunxitywe kakhulu;
• izinyo yonakele kakhulu okanye owenzakeleyo;
• i amazinyo emzimbeni.

Ukuze ufake imveliso enjalo, kufuneka ubuncinane izihlandlo ezibini ukuba babuyele wamazinyo-zamathambo. Okokuqala, ugqirha wayeqhelene radiographs ngomlomo imihlathi ngoko ukuqala unyango lwamazinyo of yidityaniso, nto leyo iya kufakwa kwi isithsaba yesinyithi. Kuloo ndawo apho ekujikeni okanye ukulungiswa okucwangcisiweyo, ususe luvo.

Crown Metal: Iintlobo

Ngokuqhelekileyo, xa isigulane ucela uncedo kugqirha wamazinyo ukubeka isithsaba intsimbi, yena wanikela iinketho ezimbini, kuxhomekeke indlela kwemveliso:

1. imveliso Diecast. It iveliswa xa ekhupha ikhethekileyo ukubhaka kwi-oveni. Le isithsaba luphawulwa ngeendonga zamafu, leyo kakuhle echaphazela ubomi nkonzo. Yenziwe isiseko (aluminiyamu chromium, nickel, intsimbi) neemethali amanene (platinum, mbala, igolide, nesilivere) ngentsimbi. Ngenxa yokuba iimveliso Umbala intsimbi kuphela amazinyo osecaleni ezase efihliweyo ngexesha lencoko. Bona afaneleka ngokupheleleyo amazinyo ezase ngomva kuba nako ukumelana imithwalo eninzi.
2. isithsaba isitampu na ngaphakathi eqhelekileyo, apho likhazimlisiwe ngomatshini ekhethekileyo ukunika imveliso imilo oyifunayo.

ngezithsaba umzekelo cast

Loo imveliso kugqalwa ngengqondo enye ethembekileyo nefakiweyo ukusuka intsila ayibe chrome. Crown (metal), intsimbi waphosa uye noludumileyo zingenakuphikwa - nto ayinayo amalungu solder, yaye oku kwenza kube ingakumbi ziqine. Igqumeke kakuhle izinyo grinded, angavumeli ukuba umxube ukuhlakaza zesamente nokunciphisa amathuba ukufota ngaphantsi ukudla kwakhe. ixesha yokusebenza - iminyaka 15-20. Aphila izithsaba uphose yokuhlala iingongoma ezininzi:

• ngenaliti le ngengqondo;
• izinyo kulungiselelwa (zisuswe 0.2 ukuya inyama 0.6 mm);
• imveliso wax ikepusi inxeba nge;
• uhombiso, ubulungeleyo kukuthi, ipolishi umphezulu yesinyithi;
• izifinyezo, kuquka ephikisanayo kunye namazinyo ezikufutshane.

Iisampulu amanqaku ezinjalo

Okwangoku, kwi-ofisi wamazinyo-zamathambo enyemba baphose izithsaba ezibengezelayo (feedback ngabo evela uninzi lwezigulane unokuviwa HIV kuphela) lweentlobo ezininzi:

1. Iimveliso ezilula umbala ngentsimbi - Uncoated.
2. Nge meko. Ukuba isigulana okungalungelaniyo le "ubuhle", kunye umnqweno wakhe Uwuthwesile kungenziwa ospeyita ngalo, uxelisa igolide.
3. Camera. Zathathelwa ingqalelo ngakumbi nezamkelekileyo imveliso elithozamisayo, zazizaliswe ngodongwe. Icala lawo elingaphambili wambu lining ceramic. Nakuba kunjalo, kufuneka balumke gqitha xa ukutya, kuba ngodongwe nga kucheba.
4. Luhlangene. Xa le nxalenye isithsaba zokufakelwa igutyungelwe iiseramikhi, kunye nabanye ezifihlakeleyo xa uncumo ukuma ngaphandle khazi.

umqhele isitampu

Zitho ezenziwa kweqokobhe mveliso, apho ukunika ifomu kuyimfuneko. Iimveliso ukuba iqokobhe ezingcakacileyo, ngoko akukho mfuneko yokuba kukho inani elikhulu amazinyo yi kwizihlunu begaya. Le isithsaba (metal) kulindeleke ukuba akukho ukutshatyalaliswa iingcambu, kwaye zigcinwe 1/3 nezinyo. Kuba imveliso yawo zisetyenziswa ngegolide okanye insimbi.

Le lula kwakheka echazwe ixabiso hayi kuphela phantsi, kwakunye ebomini encinane eziphathekayo. Gold isithsaba isitampu eyenziwe ingxubevange, oluhlasela i-90% yabo negolide.

isigaba lokuvelisa

Kukho zigaba ezithile zo ekudaleni isithsaba:

• likhanyisa umzimba nomonde zombini imihlathi ngenxa ebonisa imveliso oza kwenziwa ukuba imizuzu eli-15 de ucinezelo ekrwada;
• gypsum ephawulwe ilayini afakelweyo, kangangokuba akazange ebanzi kakhulu okanye elimxinwa;
• kulandele wax umzekelo, olusetyenziswa kumphezulu udaka - ngaloo ndlela, isithsaba (metal) ufumana imilo yokwakheka;

• on ezirhuqwa imodeli sentsimbi nesitampu wadala, nto leyo uye wanyanzelelwa ngaphandle emkhonweni;
• sokunyathela engaphandle ikhutshwa phandle usebenzisa i cinezela iqhosha lemenyu;
• Isitampu isusiwe, kwaye imiphetho imveliso, banqunyulwe kunye izikere ezikhethekileyo.

Ithuba yemveliso liphindwa zokudubula, intsimbi waba ngaphezu lukhuni kwaye womelele. Xa sokwenziwa akufunekanga ibe izitenxo neentanda.

Izinto ezibonisa ukuba ufakelo oxwebhu metal presswork

Ifaka izithsaba metal owenziwayo:

• pre-zokufakelwa baby izinyo ukuya lutshintsho njalo;
• ukugcina izinyo uphilile;
• njengenxalenye ebalulekileyo ufakelo lwe kwebhulorho ;
• ukuba izinyo wenzakele okanye ezonakeleyo yi yidityaniso ukuba akunakwenzeka ukuba siqalise uphawu.

Inkqubo yokufaka ngezithsaba

Esi siganeko wenziwa kuqhubeka ngokwezigaba 2:

1. Ekuqaleni, imveliso ibekwe okwethutyana, ukuze ugqirha uyakwazi ukubona indlela abasabela ngayo izinyo.
2. Ukuba isigulana umntu akhalaze yentlungu, kwi kutyelelo isithsaba olandelayo isusiwe, into ihlanjululwa yi yokuqala kunye isamente kumisa ngokutsha, kodwa zinc phosphate okanye iglasi ionomer.

Ukuba ngenxa ufakelo lokuqala lwafumanisa ukuba isithsaba metal (umfanekiso eboniswe ngezantsi) ebangela ukungaphatheki nomonde, ngoko ke uya kususwa kwaye iya kuqwalasela kwakhona.

imveliso Yintoni kufuneka zifakelwe kakuhle

Yinyani obuvelisiweyo kunye zabonelelwa isithsaba:

• iqokobhe nzima nebheyi izinyo;
• Kuye ifomu ogudileyo, likhazimlisiwe;
• SAGs periodontal ngendlela lekhefu ka-0.2 mm;
• izalana imilo yokwakheka le izinyo izinyo;
• wadibana khona amazinyo osecaleni, abaphikayo.

Izimo ukuba ufake

akucetyiswa ukuba abeka metal Kwezinye iimeko, xa kukho:

• bruxism;
• kukwalisa phambi ngentsimbi;
• malocclusion తీసివేయి Susa;
• umonakalo perceptible ukuba izinyo ophilileyo;
• ezintsonkothileyo ngenxa nobuhle amahlwempu kunye amazinyo zakhe sobuKristu.

Yiyiphi ingozi has isithsaba metal

Kwiimeko ezithile, le mveliso kungabangela umonakalo:

1. Ngenxa ozakulusebenza kubonakale galvanic syndrome. Oku kungenxa yokusetyenziswa aluminium eziliqela ngokuyila isakhiwo angoozenzele. Ukuxuba izinto ezahlukileyo kukhokelela ukuyilwa kwento ekhoyo galvanic. Kukho intloko, ukudumba, ezinye izifo, incasa sisinyithi, sokulibala, uvutha emlonyeni.
2. Crown (extruded) ongavelisi phezu abumbe ezahlukeneyo, ngoko ke akafanelekanga sokubuyisela ezaneleyo imisebenzi izinyo ophilileyo.
3. Le mveliso ayikho ngokusondeleyo ezikufutshane izinyo, ukudala Intermedia ezindongeni sayo, leyo engena okuseleyo. Ngoko ke, oko kuza phantsi kuwohloka ephilile.
4. Crown-ibunjwe iyahluka conductivity elungileyo thermal. Ukuba sele kwambatha izinyo nedepulpirovanny, ngexesha ulwamkelo ukutya eshushu angavela mizwa ekhathazayo.

technology Ageless

Production izithsaba ezibengezelayo yi "abaselula ngonaphakade" ubuchwepheshe kwinkulungwane edluleyo, leyo phantse yala maxesha kwiminyaka yakutshanje. Kunye ezinye iindlela zale mihla ephawulekayo afakelweyo esisigxina, uhlala nje ethandwayo. Akumangalisi oku, ekubeni esona sizathu siphambili kusebenziseka enjalo - afakelweyo zamaxabiso aphantsi kunye namandla eliphezulu.
