Ngokushesha noma kamuva, kodwa sonke sibhekene nezinkinga zamazinyo. Ngezinye izikhathi izifo zamazinyo zingabangele ushintsho ekubukeni kwabo, kodwa futhi zisuswe. Ngenxa yalokho, kunesidingo sama-prosthetics ukuze ubuyisele ubuciko bokubukeka noma ukubukeka kwe-esthétique. Enye yezinketho ezivame kakhulu ze-prosthetics noma ukubuyiselwa kwezinyo ezonakele ukusekwa komqhele we-metal-ceramic.
Izinkomba nokuphikisana nokufakwa komqhele
Ngaphezu kokubuyisela i-dentition (prosthetics), imiqhele ye-metal-ceramic ingafakwa ezimweni ezinjalo:
- ukwephulwa kokubukeka kwezinyo lakho (ukuchotshozwa, ukuchithwa kwegazi, izilonda zama koqweqwe lwawo, ukuma okungavamile, njll);
- ukwandisa ukuchithwa kwamazinyo (ukuhlolwa kwegazi kanye nokuthola);
- ukutholakala kwamazinyo angenakususwa , kanye nokuphendula okwenziwe izifo ezingxenyeni zabo zeplastiki.
Imiqhele ye-metal ceramic ayisetshenzisiwe:
- ebuntwaneni;
- uma kunokungaboni ngaso sonke isikhathi izinto ezifakwe ekubunjweni kwayo;
- ngesifo sezinsini ( periodontitis eyinkimbinkimbi kanye ne-periodontitis);
- phambi kwezifo zesifo (bruxism);
- ngokungabikho kwamazinyo amathathu noma amane elandelanayo;
- uma isiguli sinamazinyo amancane.
Ukwenza kanye nezinhlobo zemikhosi
Ukwenza imiqhele, uqhubeke emva kokuhlanza okuphelele kwegumbi lomlomo, futhi ngemuva kokususwa kwe-pulp kusuka emazinyeni azoba ngaphansi komqhele. Le nqubo inezinyathelo ezimbili:
- Ukudalwa kwamathambo. Isebenzisa ama-alloys athile (cobalt-chromium, nickel-chromium, igolide-palladium, igolide-platinum).
- Isicelo esihlokweni se-ceramic ekhethekile emigqeni ehlukahlukene, ngayinye ekhishwa ngokushisa okuphezulu.
Ngesikhathi ukusetshenziswa kwezingubo ze-ceramic, umbala womqhele we-ceramic-ceramic uhlelwe umbala wamazinyo ayo, unqume ngesikhathi kususwa isikhunta.
Ngokuya ngezindlela zokukhiqiza ezisetshenzisiwe, izinhlobo eziningi zemikhosi yensimbi-ceramic zihlukaniswa:
- Amakhanda awenziwe ngesakhiwo esenziwe ngethusi. Kulokhu, amacala okukhubazeka nokungalungi ekubunjweni akuvamile.
- Amakhanda enziwe ngomshini wokwenza umshini okhethekile. Sinesakhiwo esilinganiselwe kakhulu emgqeni ngamunye wamazinyo.
- Amakhanda, lapho ukumbozwa kwe-ceramic kukhuliswa khona nokunciphisa okwenziwe ngesikhathi esisodwa sensimbi ye-skeleton volume.
Ukunakekelwa nokuphila komsebenzi
Udokotela usitshela indlela yokunakekela kahle isikhumba somlomo emva kokufakwa komqhele we-metal-ceramic. Kodwa imithetho eyisisekelo yokunakekelwa ayifani nokukhathalela amazinyo avamile, futhi ihlanganisa ukuxubha amazinyo njalo izikhathi ezimbili noma kathathu ngosuku. Ngaphezu kwalokho, kunconywa ukuthatha izivivinyo zokuvimbela udokotela wamazinyo kanye noma kabili ngonyaka.
Ukuphila komsebenzi wezinsimbi zensimbi-ceramic, ngokugcinwa kwamasu okukhiqiza kanye nama-prosthetics efanele, kuvela eminyakeni engu-10 kuya kwengu-15.
Ukuvela kwezinkinga nokususwa komqhele
Uma kusetshenziselwa ukugqoka isiqephu somqhele we-metal-ceramic, futhi ukubukeka kokuhleleka kuyaphazamiseka, kukhona amathuba okubuyiselwa. Kodwa kufanele kuqashelwe ukuthi lesi yisisombululo sesikhashana kwenkinga. ubuqotho bendaba buphazamiseka futhi le nkinga izophinde iphakame ngokuhamba kwesikhathi. Uma i-chip ibonakale ngaphakathi, imane nje igweme ukugwema ukuhlukumezeka olimini. Kunoma yikuphi, ngesikhathi sokuqala, kunconywa ukuba esikhundleni somqhele owonakele.
Njengoba umqhele ukhonjwe ngamakhemikhali akhethekile wezinyosi, ukususwa kwalo okumele kutholakale kufanele kwenziwe ngokusebenzisa idivayisi ye-ultrasonic. Ngaphansi kwethonya laso, isamente libhujiswa, futhi umqhele ususwe kalula.
