Nā mea puaʻa no ke Alahaka niho

Nā ʻano alahaka niho

Hoʻopili ke alahaka niho i nā āpau ma waena o nā niho me ka hoʻohana ʻana i nā lei aliʻi a i ʻole nā ​​ʻēheu paa i ke alahaka. ʻEkolu ʻano o nā alahaka niho:

Alahaka Kuʻuna: ʻO ke alahaka i hoʻohana pinepine ʻia, kahi alahaka kuʻuna he ʻelua lei aliʻi a hiki i ʻekolu alahaka. Hoʻopili ʻia ka lei aliʻi i nā mea ʻelua nā niho maikaʻi ma kēlā ʻaoʻao kēia ʻaoʻao o ka hakahaka kahi e kau ai ke alahaka.

Cantilever Bridge: Hoʻokahi wale nō lei aliʻi kēia koho a hiki i ʻekolu alahaka. Pono nā alahaka Cantilever inā loa'a nā niho pili lei aliʻi, hoʻokahi wale nō niho o ka mea maʻi e pili ana i ka niho nalowale, a i ʻole maikaʻi loa aesthetically.

Nā alahaka i kākoʻo ʻia i ka hoʻokomo ʻana: Ma kahi o ka hoʻohana ʻana i nā niho olakino e kākoʻo i ka uwapo, implants paa ia ma kahi. ʻO kēia ka mea paʻa loa a lōʻihi koho alahaka niho.

 

Alahaka kahua niho

 

Nā pōmaikaʻi o ke alahaka niho

Eia nā pōmaikaʻi o ke koho ʻana i kahi alahaka ma luna o nā niho niho a i ʻole nā ​​​​implants.

ʻAʻole pono i nā alahaka niho ke ʻoki. Inā ʻaʻole i kākoʻo ʻia kāu implant alahaka ma kahi, ʻaʻole pono ʻoe i ka ʻokiʻoki e hoʻihoʻi i kou minoʻaka. Kuʻuna ʻO nā alahaka, nā alahaka cantilever, a me nā alahaka ʻo Maryland he maʻi maʻi wikiwiki a maʻalahi nā kaʻina hana i hiki ke hana i ka hele hoʻokahi a ʻaʻole koi i ka hoʻōla lōʻihi.

ʻOi aku ke kumukūʻai o nā alahaka niho ma mua o nā implants. ʻO ke kālā ka mea nui loa ka poʻe e noʻonoʻo i ka wā e hoʻihoʻi ai i nā niho. He emi loa nā alahaka pipiʻi no ka mea ʻaʻole koi lākou i ka ʻokiʻoki a i ʻole e like me ka pololei o ka niho implants.

ʻOi aku ka palekana o nā alahaka niho ma mua o nā niho niho. Hoʻopiʻi pinepine ka poʻe maʻi me nā niho niho e neʻe a hāʻule paha ko lākou mau niho i ka wā e ʻai ai a kamaʻilio paha. ʻO nā alahaka pili i nā niho ʻē aʻe a i ʻole nā ​​mea i hoʻokomo ʻia, ʻaʻole i ka ʻāʻī.

ʻOi aku ka ʻoiaʻiʻo o nā alahaka ma mua o nā niho niho. Pēlā nō, nā niho niho pinepine e neʻe i loko o ka waha, he mea ʻoluʻolu ʻole i ka mea maʻi akā ʻike ʻia ka poe a puni. ʻO nā alahaka niho ke nānā a like me nā niho maoli, no laila aneane ʻaʻohe mea e ʻike ʻaʻole maoli lākou!

ʻO wai ka mea maikaʻi no ke alahaka niho

Ke ulu aʻe ko mākou mau niho, pono nā alahaka, i hoʻohana ʻia e pani niho nele, hiki ke mahuahua.

Hāʻawi kā mākou Bloomden i kā mākou mea kūʻai aku i kahi koho o nā mea alahaka e like me: PEEK (Polyetheretherketone), PMMA, Wax, Zirconia.

1. Peek poloka

Ke hoʻohālikelike ʻia me nā mea kuʻuna, loaʻa i ka PEEK nā pōmaikaʻi nui. He kiʻekiʻe ratio ikaika-a-kaumaha a me na waiwai elastic e like me ka iwi kanaka. Ua loaʻa ʻAʻole ka pōʻino, haʻahaʻa loa ka ʻai ʻana i ka wai, a he radiolucent, ʻo ia hoʻi ʻAʻole ʻike ʻia e nā X-ray. He liʻiliʻi a ʻaʻole hoʻi nā hōʻike e pili ana i ka maʻi maʻi i nā maʻi. Loaʻa i ka PEEK kahi waihoʻoluʻu kūlohelohe, ʻaʻole like ʻole, ʻo ia hoʻi ke nānā aku ʻoi aku ka kūlohelohe i ka waha o ka mea maʻi, a no ka mea hiki ke hoʻolālā ʻia a hana ʻia, ʻo nā niho niho i hana ʻia mai PEEK he pololei a kūpono. Ke hoʻohālikelike ʻia me nā implants metala, ʻoi aku ka maikaʻi o ka PEEK no ka mea e hoʻopau i kekahi ka ʻono metala a ʻaʻole i maʻalahi i nā hoʻololi wela i hana ʻia e ʻai.

 

Na Poka PEEK

 

Nui nā pōmaikaʻi ʻē aʻe o PEEK, e like me:

• Hiki ke hoʻopilikino ʻia a wili ʻia e like me ka mea maʻi waha

• ʻAʻohe mea wela a uila paha

• ʻAʻohe ʻeha a hoʻonāukiuki paha i ka mea maʻi

• Paʻa, hoʻoheheʻe wela o 340°C

• Kūpale kūpale

• Māmā, maʻalahi no ka poʻe maʻi e ʻaʻahu

• Hoʻopau koke i ka wela o ke kino, me ka manaʻo "kūlohelohe"

2. Nā poloka PMMA niho

ʻO PMMA niho kekahi o nā koho no nā alahaka niho.

• PMMA maʻamau: hoʻohana ʻia ia i ka hana ʻana i nā ʻano manawa pōkole ka ho'iho'i 'ana i nā niho, me nā hale pa'akikī e like me nā implants a i 'ole alahaka.

• PMMA hikiwawe: kiʻekiʻe tensile a flexural ikaika no ka hapa wehe nā papa hoʻoikaika niho, hoʻihoʻi manawa.

• ʻO Multilayer Pmma: he mea hoʻonaninani aesthetic i hui pū ʻia ma mua o ʻelima mau ʻāpana kala e hāʻawi i ka hoʻihoʻi ʻana i kahi hiʻohiʻona kūlohelohe kiʻekiʻe.

• Hoʻomaʻemaʻe PMMA: kūpono ia no ka hana ʻana i ke alahaka niho.

3. Nā poloka wax

Hoʻohana pinepine ʻia nā poloka wax no ka pale ʻana i nā braces mai ka huhū o ka waha palupalu ʻiʻo, hiki ke hoʻohana ʻia i ka hana ʻana i nā alahaka niho.

4. Nā poloka Zirconia

• Aesthetics: He ʻoiaʻiʻo a nani ka hoʻihoʻi ʻana o nā niho seramika āpau helehelena, a ua like ke kala me na niho maoli. ʻO ka mea nui loa ʻO nā niho-ceramic a pau ke ʻike maikaʻi a me ka refraction, a ma laila mai laina ʻeleʻele ma ka ʻāʻī o ka niho, i hiki ai i ka ʻāʻī o ka niho loaʻa pū kekahi hopena aesthetic maikaʻi, hiki ʻole ke hopu niho porcelain maʻamau.

• Biocompatibility: ʻO Zirconia no nā noi lapaʻau a me nā niho nā waiwai maikaʻi e pili ana i ka biosafety. I loko o nā makahiki, nui ka nui o ua hōʻike ʻia nā hihia hoʻokolohua a me nā lāʻau lapaʻau ʻaʻohe zirconia i mea ʻino iwi a me nā ʻiʻo ʻiʻo palupalu, ʻaʻohe hōʻike e pili ana i nā hopena maʻi.

• Ka ikaika kiʻekiʻe a me ka nui:

(1) Zirconia ceramics he yttrium-stabilized zirconia ceramics me ke kiʻekiʻe ikaika flexural. I kēia manawa, loaʻa ka ikaika o nā mea i hoʻopaʻa ʻia ma Kina a hiki i 900MPa, aʻo ke kūlana aupuni no nā mea niho he 100MPa.

(2) Hoʻohālikelike ʻia me nā mea hoʻihoʻi a pau-ceramic, ka ikaika o zirconia mea hiki i nā kauka ke hoʻokō i ka ikaika kiʻekiʻe loa me ka ʻole ka wili ʻana i nā niho maoli o ka mea maʻi. I waena o lākou, ʻo Vita all-ceramic ʻike pū ʻia ʻo zirconia ʻoi aku ka hoʻohui-yttrium a me ka oxide hoʻopaʻa ʻia ma ke ʻano he keramika kila.

• Ka pololei: Hoʻokō ʻia ka hana ma o ka hoʻolālā kōkua kamepiula, laser ka nānā ʻana, a me ka wili ʻana i ka polokalamu kamepiula. He mea hōʻoia i ka pololei o ka hoʻoheheʻe ʻia a me ka paʻa ʻana o ka lihi maikaʻi, e kūpono ana ka niho porcelain maikaʻi me ka abutment ma ka waha o ka mea maʻi.

• ʻO ka radioactivity haʻahaʻa: ʻO nā kūlana o ka State Food and Drug Administration loaʻa nā kūlana koʻikoʻi no nā mea seramika āpau ma ka mākeke, a hiki wale nō hoʻohana ʻia e like me nā mea lapaʻau ma hope o ka hoʻokō ʻana i nā koi o ka radiological nā hoʻokolohua. ʻAʻole wale nā ​​koi no ka zirconia, akā no ka porcelain kāhiko, alumina, aniani seramika, etc. Hōʻike nā hoʻokolohua i ka ʻO ka radioactivity o ka pauka zirconia maʻemaʻe ʻaʻole ia he haʻahaʻa ma mua o ke aniani nā seramika, akā haʻahaʻa hoʻi ma mua o ka iwi iwi kanaka.

E ʻimi i ka hoʻihoʻi kūpono no kāu minoʻaka

Hiki iā ʻoe ke koho i nā mea alahaka kūpono loa e like me kou makemake malalo o ke alakai ana a kau kauka. ʻOi aku ka hilinaʻi, ʻoi aku ka maikaʻi o ka minoʻaka. Ua kūpaʻa mākou e hāʻawi iā ʻoe i ka minoʻaka maikaʻi loa. Inā makemake ʻoe i nā mea niho, e ʻoluʻolu kāhea iā mā˚ou.
