Ngokunyuka kwedijithali kunyango lwamazinyo, izikena ze-intraoral kunye nemibono yedijithali yamkelwe ngokubanzi ngoogqirha abaninzi.I-Intraoral scanners isetyenziselwa ukubamba imbonakalo ethe ngqo yamazinyo ezigulane.Bavelisa umthombo wokukhanya kwi-arch yamazinyo kwaye imifanekiso iya kubanjwa zinzwa ze-imaging ezicutshungulwa yisoftware yokuskena, evelisa iingqimba zamafu.Ezi ngqimba zamafu ziyacutshungulwa kwaye zenze imodeli yomphezulu we-3D.Umkhuba wokwanda kokusetyenziswa kweescanner ze-intraoral kwiinkqubo zemihla ngemihla zoogqirha bamazinyo kukhokelele kwimfuno yokuvavanya ngokufanelekileyo umgangatho wedatha ye-intraoral digital impressions.
Nangona kunjalo, ukulinganisa umgangatho wemodeli ye-3D yomhlaba akukho lula njengokuyijonga nje, kuba ngamanye amaxesha imodeli ekhangeleka kakuhle ayilingani nomgangatho olungileyo wedatha yokuskena.Isenokugqwethwa ngexesha lenkqubo kwaye ikhompyuter emva koko igudise yonke into, nto leyo ikwenza uzive ngathi uyithathile yonke into, kodwa inyaniso kukuba uphoswa ziinkcukacha ezibalulekileyo eziya kuphelela ekubuyiselweni ngendlela engafanelekanga.Ibhlog kukufundisa indlela yokuvavanya umgangatho wedatha yembonakalo yedijithali kwimiba esisiseko.
Ukuchaneka kwedatha
Akukho nto ibaluleke ngaphezu kokuchaneka, i-scanner ye-intraoral kufuneka iqale ibe namandla okwenza i-digital impression echanekileyo.Kufuneka sazi ukuba ukuchaneka kungumlinganiselo wenyaniso nokuchaneka.Inyaniso ichazwa 'njengokusondela kwesivumelwano phakathi kolindelo lwesiphumo sovavanyo okanye isiphumo somlinganiselo kunye nexabiso lokwenyani'.Ukuchaneka kuchazwa 'njengokusondela kwesivumelwano phakathi kwezibonakaliso okanye amaxabiso obungakanani obulinganisiweyo afunyenwe ngokuphindaphinda imilinganiselo kwizinto ezifanayo phantsi kweemeko ezichaziweyo'.Ngamafutshane, ukunyaniseka kukukwazi ukwenza umlinganiselo ukuze ungqinelane nelona xabiso lomlinganiselo olinganiswayo.Ukuchaneka kukukwazi ukuphindwa komlinganiselo.
Iskena sangaphakathi kufuneka sibe nenyaniso ephezulu kwaye loo nto ithetha ukuba kufuneka ikwazi ukungqamanisa ubunyani ngokusondeleyo kangangoko: imodeli enenyani ye-3D ebanjwe sisikena kufuneka ifane nemodeli eyiyo ngokusondeleyo kangangoko kunokwenzeka, ngokutenxa kuncinci kwinto eyinyani.Ngokubanzi, iindlela zokuvavanya ubunyani be-IOS kukugqithisa izikena zayo kunye neskeni sereferensi esifunyenwe ngomatshini onamandla weshishini.Emva kokudityaniswa kwezi modeli, isoftware enamandla yokubuyela umva ingasetyenziselwa ukuvelisa iimephu zemibala ebonisa umahluko phakathi komphezulu we-IOS kunye nemodeli yereferensi kwinqanaba le-micron.Ukubala ukuchaneka, ngokulula ukutyhutyha iimodeli ezahlukeneyo ezithathwe ngesikena se-intraoral esifanayo ngamaxesha ahlukeneyo kunye nokuvavanya kwakhona iyantlukwano kwinqanaba le-micron.
Kule grafu, unokujonga idatha yokuchaneka kwembonakalo, enemibala eyahlukeneyo emele ukutenxa kowona mzekelo.
Kubalulekile ukuqaphela ukuba i-IOS inokuba nenyaniso ephezulu kodwa ichanekile ephantsi, okanye ngokuphambanayo.Kuzo zombini ezi meko, uluvo lwedijithali alwanelisi kuba luyakuchaphazela ukuchaneka ngokubanzi ngoko kuya kuba nefuthe elibi kumsebenzi wokufakelwa kagqirha wamazinyo.
Kubuyiselo lwexesha elifutshane (elifana nokubuyisela izinyo elinye okanye iprosthesis esisigxina esisigxina), asinakukhathalela malunga ne-micron enye yempazamo kuba ayibalulekanga ngokwezonyango.Nangona kunjalo, xa kufikwa kubuyiselo lwexesha elide, iya kuqokelela ezi mpazamo zingabalulekanga ngokweklinikhi kwakhona kwaye kwakhona kwaye kwakhona, ngoko ke ngaxa lithile inani lilonke leziphoso obuziqokelele zinokuba zibalulekileyo ekliniki.
Ngokufanelekileyo, ukukhetha iskena esichanekileyo sisigqibo esicetyiswayo, kodwa ngokuqhelekileyo siza nexabiso eliphezulu.Kuya kufuneka ukhethe iskena esisekwe kuhlahlo lwabiwo-mali lwakho kunye nemfuno yakho, ukuba nje iskena singaphakathi kokuchaneka okwamkelekileyo ngokwezonyango.
Ubukhali beDatha
Ngaphandle kwedatha yovavanyo evela kwiarhente yovavanyo lobuchwephesha/iqela lesithathu elithenjiweyo, okanye amava akho obuqu kunye neskena sangaphakathi, awukwazi ukuxelela ukuba ingaba idatha ichanekile na ngokusuka kumbono wedijithali kuphela.Makhe sijonge imiba yomgangatho wedatha onokuthi uyiqwalasele.
1. Ubukhali bomda weGingival
Xa ufumana idatha yedijithali ye-iOS kwaye uyithumele kwi-software ye-3D yomfanekiso ukuze ujongwe, into yokuqala ongayenza kukugweba ubukhali bomda we-gingival.Umda wemida yeyona nto iphambili kwiingcali zamazinyo ukwenza amazinyo emboleko.Umbono omhle wedijithali kufuneka ube nomgca womgca ocacileyo ukwenzela ukuba ukubuyisela kwenziwe ngokuchanekileyo.Ukuba umgca we-margin awucacanga, ekugqibeleni uya kuchaphazela ubunyani bezinto ezibonakalayo zedijithali kunye nomgangatho wokubuyisela okokugqibela kwaye kukhokelela ekungaphumelelini okufanelekileyo.
2. Ukugqwetheka
Kufuneka ujonge ngononophelo idatha ukuze ubone ukuba ibonakala igqwethekile okanye inemingxuma engenanto, enokuthi ibangelwe kukubonakaliswa kolwelo, njengamathe.Oku kungenxa yokuba i-IOS ayinako ukwahlula phakathi kolu hlobo lokubonisa kunye nawo wonke umfanekiso owuthathayo.Gcina ukhumbule ukuba umise indawo, kwaye idatha ephosakeleyo / elahlekileyo kufuneka ihlaziywe.Ukuba isicwangciso somsebenzi wokuskena sichanekile kwaye akukho kuphinda-phindwa kolunye ulwelo kunye nokugqwetheka kusenzeka rhoqo, ngoko iskena sangaphakathi asithembekanga kwaye asifanelekanga ukusetyenziswa ekliniki.
3. Iinkcukacha zomphezulu oclusal
Jonga nje imiphezulu ye-occlusal emfanekisweni, umgangatho olungileyo wedatha yedijithali iya kubonisa imingxuma eneenkcukacha kunye neentanda.
Umbala weDatha
Ubunyani bombala kunye nesisombululo sedatha yokufumana nayo ibalulekile, nangona kunjalo, kuxhomekeke kwiikhamera ngaphakathi kweskena kunye nesoftware.Ikhamera enamandla kunye nesoftware inokuvelisa imodeli yombala we-3D enesisombululo esiphezulu kwaye oku kunokuba sisixhobo esinamandla sokuthengisa kwisenzo sakho, njengoko izigulane zingathanda ukubona imodeli yazo yamazinyo njengenyani kangangoko kunokwenzeka.Ngoko xa ugqiba ukuskena, uthelekisa idatha kunye namazinyo okuqala esigulane, umfanekiso osondeleyo kumbala wamazinyo okwenene ukumgangatho ophezulu.
