Uye ungaita sei kuti zvese zvishande pamwe chete?
1. Masisitimu epadivi pechigaro: Kumhanya & Chiitiko chekushanyira kamwe chete
CEREC, Planmeca, Ritter Concept - masisitimu aya anovimbisa chinhu chimwe chinodiwa nevazhinji vanachiremba vemazino nevarwere: mazino ezuva rimwe chete .
1.1 Kushanda zvakanaka kwenguva
- Murabhoritari yechinyakare: vhiki imwe kusvika mbiri (pfungwa → mutumwa → basa remurabhoritari → kudzoka → kuyedza).
- Padivi pechigaro: chakadzvanywa mumaawa maviri nematatu.
- Rubatsiro rwemurwere: kushanya kamwe chete kunorapwa nechirwere chepfungwa, hapana kunetseka nezvekupisa kwemuviri, hapana rwendo rwechipiri.
1.2 Matanho ekiriniki ari nyore
- Hapana zvinhu zvemazuva ano zvekuona (zvakanakira varwere vane gag reflex yakasimba).
- Kuskena kwedhijitari kunogona kuongororwa nekukasika kuti uone kana muganhu wakajeka.
- Dhizaini, chigayo, sinter, glaze - zvese zviri pasi pesimba rako.
1.3 Makabati akanakisa epadivi pechigaro
- Kuisa mukati/kuiswa kwepashure (posterior) - humbowo hwakasimba. Zvidzidzo zvekiriniki zvenguva refu zvinoratidza kubudirira kwe88.7% mushure memakore 17 uye 87.5% mushure memakore anosvika 27 ekushanda mukiriniki yeCAD/CAM inlays uye onlays dzechigaro[1] .
- Korona imwe chete yekumashure (premolar/molar) - inochinjika zvakanyanya.
- Korona dzechinguvana - dzinogona kugadzirwa padivi pechigaro, kunyange zvazvo kuti zviite nekukurumidza, tembiricha yakagadzirwa kare + bis-acryl inogona kukurumidza.
- Ma veneer ari nyore (1-2 units, zviri nyore kufananidza mavara).
Miganhu yacho yakajeka: sarudzo shoma yezvinhu (kunyanya magirazi eceramic uye resin blocks). Zvigadziko zveCAD/CAM zvepachigaro zvinowanzopa simba rekuchinjika kubva pa160 MPa (feldspathic) kusvika pa420 MPa (lithium disilicate) uye kusvika pa1200 MPa (zirconia); hapana layering yakaoma yemayuniti akawanda epamberi, uye multi-layering zirconia inoda kugadziriswa murabhoritari.
2. Simba Risingakundike reLabhoritari: Zvishandiso, Runako & Kuoma Kwazvo
Kana wangopfuura nzvimbo yekunyaradzwa "yekupinza kamwe chete", kukosha kwerabhoritari kunobva kwanyatsojeka.
2.1 Upamhi hwezvinhu
- Chigaro chinogayiwa: lithium disilicate (IPS e.max CAD), mabhuroko eresin, zirconia inonyungudika nekukurumidza.
- Murabhoritari inowanikwa: multi-layered zirconia (20+ layers), lithium silicate, pressed ceramics, hybrid ceramics, PEEK, fiber-reinforced composite, noble metal-ceramics - nezvimwe zvakawanda.
- Zvimwe zvinhu zvinopenya zvakanyanya kana kuti zvine simba guru zvinoda kusvinwa kana kudzvanywa kwakakosha uko hita yepadivi pechigaro isingakwanise kuita.
2.2 Runako rwepamusoro - kurongedza nekupenda zvidimbu zvakasiyana-siyana
Mavara eparutivi pechigaro anokupa ruvara "rwakajairwa". Nyanzvi yehunyanzvi inogona:
- Vaka dentini nedenderedzwa (dentini, enamel, incisal, porcelain yemhando yepamusoro).
- Kupenya kwemaziso kwakada kufanana, kupenya kwemaziso, mavara machena kana mitsetse inopenga.
- Gadzirisa mazino ari pedyo nerimwe nerimwe.
Pamakesi ekushongedza epamberi (≥3 veneers, kusviba kwakanyanya, mavara etetracycline), chigaro hachina kugadzirirwa.
2.3 Kugadziriswa kwakaomarara
- Mabhiriji ekuisa zvinhu mumichina, maHader bars, mabutment akagadzirwa nemaoko - anoda ma interfaces akanyatsojeka uye nzira dzekugaya.
- Kugadzirisa muromo wese (>10 units) - nguva yekugaya padivi pechigaro ingave maawa maviri nematatu ekucheka chete; varwere havazomiriri kwenguva yakareba kudaro.
- Mafuremu emazino ekubvisa chikamu anogona kubviswa - anoda kuumbwa kana kuti laser sintering.
2.4 Humbowo hwekuti margin fit inokodzera sei
Kuenzanisa zvakananga kwekorona dzeceramic dziri padivi pechigaro nedzepa lab kwakawana simba guru rekugadzira pakuenzanisa marginal fit (p = 0.0064), zvichiratidza kuti nzira yekugadzira inokosha.[2] . Zvakakosha kuti, kunaka kwekugadzirira pachako kune simba guru: zvidzidzo zvinoratidza avhareji yemikana ye36.6 μm yekugadzirira kwakanaka, 67.2 μm yekugadzirira kwakanaka, 87.6 μm yekugadzirira kwakanaka, uye 104 μm yekugadzirira kusina kunaka - zvisinei nekuti ndeipi sisitimu yechigaro inoshandiswa.[3] Izvi zvinoratidza kuti kugadzirira zvakanaka ndicho chinhu chinonyanya kukosha pakuwana mikana chaiyo, kungave uri pachigaro kana kuti uri murabhoritari.
3. Mhando yeHybrid: Kuskena muhofisi + Kugadzira/Kugadzira muLab
"Zvakanakisisa Panyika Dzese" Zvinonyanya Kushanda - pamwe ndiyo nzira yedhijitari inoshanda zvakanyanya mazuva ano, kunyanya kune avo vasingade kuisa mari mukugadzira michina yemagetsi mukati mekambani.
