Iplastiki yezonyango yePlasi yeBandla - i-Peramic emhlophe

Iipropathi zoomatshini kunye nokusetyenziswa kweklinikhi ye-Plastics-Cestics yePlastiki yePlastiki yePlastiki ye-Peestic kwi-Peek Act kwi-SEATIONS ihambelana nesiqinisekiso se-FDA

Sonke siyazi ukuba izinto zamazinyo kunye nezixhobo ezingundoqo ziyafuneka ukuba zibe nokuqhekeka okuphezulu kunye nokungakhathali okutyebileyo, zihambelana ngokuchanekileyo nemorpholog ye-morpholor, kwaye ibaluleke kakhulu, ine-modlul efana ne-dentin (18,6 GPA). I-elastic mofulis yempahla yamazinyo idlala indima ephambili ekusasazeni uxinzelelo ngaphakathi kwe-dentin, echaphazela ukusebenza kwesandiso kunye nezinyo. Izinto zeposi kunye nemodyuli yolutsha kufutshane ne-Dentin ngokubanzi zivelisa uhlaziyo loxinzelelo olufanelekileyo, kunye noxinzelelo oluphezulu kwiposti kunye noxinzelelo oluphantsi kwiingcambu zenziwe kakuhle kunye ne-Post-Dentin Interming.

Iiposti zentsimbi kunye nezithuba ze-ziirconia zinemodyuli ephakamileyo ye-elasticy kune-dentin, edala uxinzelelo oluhlanganisiweyo kwingcambu enokubangela iqhekeza ngelixa isithuba sihlala sihleli. I-fiber-iqinisa i-piles eguqulweyo (i-FRC) ibonisa ukusasazeka okulinganayo ngakumbi kwaye, nangona umngcipheko weqhekeza lengcambu liphantsi, iifayile zichaphazeleka kakhulu ekuqhekekeni.

Nangona kunjalo, ngenxa yeepropathi zayo ezintle, iiposti ze-FRC zisezona zixhobo zisetyenziswayo zeposi kunye nezilungiso, nangona kusekho iintsilelo. Iiposti zangaphambili ze-FRC azinakuthelekisa ubume beengcambu zemvelo kwaye zifuna ukuqhuba ngokukhethekileyo ukulungiselela ingcambu, enokwandisa ukusetyenziswa kwe-dentin kunye nokunyusa ubungozi bokuqhekeka kunye nokwenza ubumbeko lweengcambu.

Iziphumo zamva nje zibonisa ukuba i-Peek ibonisa i-aesthetics engcono kune-alces yentsimbi kwaye ithelekiswa kwi-FRC xa isetyenziswa njenge-Post kunye nezinto ezisisiseko; Imodyuli ye-elastic yayo ephantsi (3 ukuya kwi-4 GPA) ithelekiswa nesona sizathu sezinyo (18.6 GPA), kwaye i-GPR yayo ye-12 GPA) kunye ne-CFR-Pek (i-18 GPA). I-fea iqinisekisile ukuba amandla e-rive ayile enye i-FRC okanye i-fiberglass kwiposti kunye nokulungiswa kwezinto eziphambili. Ukuya kuthi ga ngoku iincwadana ezinemifanekiso echaphazelekayo, iipiki ze-piek kunye ne-fiberglass ibonakalise amandla afanayo kunye nokusasazwa koxinzelelo kuvavanyo lwe-Bite Lovel, kunye neePieks ze-Pever zibonisa ukusasazwa koxinzelelo olufanelekileyo kwiifayile ze-fiberglass kunye neTitanium. kunye neendlela zokusilela. Nokuba ubuyiselo kunye nezinyo ziphantsi koxinzelelo lwendlela okanye i-thermal.

Ngokukwanjalo, izithuba zangaphambili ze-Peek zinciphile uxinzelelo ngaphakathi kwesamente, i-cept yesamente, kunye ne-core yesixhobo esithelekiswa nezikhundla ze-fiberglass, ngelixa sibonisa iziphumo kwi-dentin. I-carbon fiber kunye ne-fiber yeglasi inokuhlanganiswa ne-Peek ukungaphumi nje ukuqina kwe-peek kodwa ikwanikezele nge-elastic mody efana ne-dentin, kunye ne-CFR-Peeks ibonisa i-dentin ephantsi xa kuthelekiswa ne-dentin. Gwenxa uxinzelelo. I-FRC, gfr-peek kunye nePolyetherketone yetonitone.

Ngaphaya koko, olona xinzelelo luphezulu lwenzeka kwizithuba zeCFR-Peeks kunye nezonyango ezisezantsi zifunyenwe kwi-dentin-post, ephakamisa isiphumo sokukhusela esidluliselwa ngembonakalo efanayo ye-elastic. Ngokuphathelele impembelelo yetekhnoloji yokufezekisa i-Peek, i-FOA ingasetyenziselwa ukuqikelela indlela yokubuyiselwa kwe-Post-And-Core kunye nokuvavanya ukuchaneka kwe-Peek yenziwe ngeendlela ezahlukeneyo. Kuxelwe kwangaphambili ukuba ukuchaneka kweekholaki ze-Peek eziHight Peek kuya kuphathelele ukuthengisa iikholam / kwi-cam feek. Intsebenzo ePhakamileyo ye-Peek njenge-Post kunye nezinto eziphambili zibonakalisiwe kwi-vitro naseVivo. Izithuba ze-Peek zibonise ukuxhathisa okuphezulu okuphezulu xa kuthelekiswa nezithuba ze-Polymer (i-pic) ezidityaniswe nezithuba ze-FRC, kodwa iziphumo ze-Doths ze-Peet kunye ne-PRC zazingalunganga njengakwi-FRC. Umthwalo oqingqiweyo weepiki ze-Peks uphantsi kakhulu kune-nickel-chromium (i-NRR) ye-alloy piles, kwaye inesichasi esifanayo sokuqhekeka kwi-Nanoceramic I-fiber fiber fibles yesona sixhathisi esikhulu ka-zircocoia, silandelwa yi-ZIRCONIA PALES kunye nezikhundla ze-zueve, kunye nokuqhekezwa kwezithuba ze-PARCE azisebenzi kakuhle xa kusetyenziswa iingcambu zobungakanani beengcambu zasetyenziswa.

Uninzi lweentsilelo zepile zepeyili zibangelwa kukunxiba kunye nokukrazula kwimfumba kunye ne-core kwaye zilungiswa. I-Pek yavavanywa kwimida yemodeli ye-bovine ye-bovine, kodwa izithuba ze-Peveent zafunyanwa zineepropathi ezimbi ngakumbi kunezithuba ze-fiberglass xa ilungisa i-canals evuthayo. I-Peek iyaqhubeka ithandwa phakathi kwabaKhuseli njengeposi kunye nendawo ephambili ngenxa ye-aesthetics yayo elungileyo kunye neepropathi zoomatshini. Ukulungiswa kungabizi kakhulu kwaye iziphumo ziyanelisa. Ukuqukumbela, kukho ubungqina obukhulayo wobuchule be-Peek njengendawo kunye nezinto eziphambili, kodwa ukuba i-peek inokuphucula ukusinda kwexesha elide ukusinda kwamazinyo kunye nokubuyiselwa kufuna uphando olunye.
