ʻO Bloomden PEEK - ke ʻano metala ʻole i ka ʻenehana niho

Hoʻomaka i ka Polyetherketone (PEEK)

ʻO ka Polyetheretherketone (PEEK) kahi mea polymer kala niho synthetic i hoʻohana ʻia ma ke ʻano he biomaterial i ka orthopedics no nā makahiki he nui. I ka makahiki 1978, ua ua hoʻomohala ʻia e kahi hui o nā ʻepekema Pelekane. Ma hope mai ua hoʻolaha ʻia ʻo PEEK no nā hana ʻoihana. Ma ka hopena o nā makahiki 1990, he mea nui ka PEEK moho thermoplastic hana kiʻekiʻe e pani i ka implant metala ʻāpana.

• Na Leialii PEEK

Hoʻokumu ʻia ka ʻili me ka sulfuric acid i kahi ʻili i hoʻololi ʻia hiki iā ia ke hoʻopaʻa ʻoi aku ka maikaʻi me nā composites resin hydrophobic. Ua ___ ia Ua ʻike ʻia ʻo ka ikaika o ka hoʻopaʻa ʻako ʻana i ka resin composite ciment ua like ke kiʻekiʻe 15.3 7.2 MPa ma hope o ka mālama ʻia ʻana i loko o ka wai ma 3780 C no 60-90 mau kekona me ka sulfuric. kiʻi ʻakika. ʻO ka hoʻopaʻa ʻana me ka ʻakika Piranha a me ka hoʻohana ʻana i nā mea hoʻopili paʻa hōʻike ʻia e hana i nā ikaika paʻa tensile resin composite e like me 23.4+/-9.9MPa i nā hiʻohiʻona PEEK kahiko. ʻAʻohe ʻokoʻa koʻikoʻi o ka pili tensile ikaika ma waena o nā lei aliʻi PEEK a me nā abutments niho me ka hoʻohana ʻana i ka ea abrasion a ʻenehana etching acid sulfuric. Hōʻike kēia mau haʻawina e hiki ke hoʻohana ʻia ka PEEK ma ke ʻano he ka uhi ʻana i nā mea ma lalo o ka resin composites.

• PEEK Abutment

Ke noʻonoʻo nei i ka biocompatibility lawa, hiki i nā abutments ho'ōla implant i kūkulu ʻia me ka PEEK. ʻAʻole i loaʻa ka hoʻihoʻi ʻana o ka iwi a me ka ʻiʻo palupalu ʻokoʻa loa ma waena o ka PEEK a me ka titanium abutments. Eia hou, ka waha ʻO ka microflora i hoʻopili ʻia i nā abutments PEEK ua hoʻohālikelike ʻia me nā abutments i hana ʻia titanium, zirconia, a me ka polymethyl methacrylate. ʻO ka pili pili o ka ʻO ka modulus elastic o ka iwi i ka ʻili PEEK e hōʻemi i ka pale koʻikoʻi hopena a paipai i ka hoʻoponopono hou ʻana o ka iwi. No laila, hiki i ka PEEK ke hōʻoia i kahi mea ola ʻokoʻa i ka titanium no ke kūkulu ʻana i nā abutments implant.

• PEEK i nā Prostheses hiki ke hoʻoneʻe

Nā niho niho hoʻoneʻe kuʻuna (RDPs) me nā kiʻi chrome-cobalt a me nā kaula. ua puka mai ma ke ʻano he koho lapaʻau maʻalahi a wānana no ka ka hoʻoponopono ʻana i nā maʻi edentulous hapa. ʻAʻole ʻae ʻia ka aesthetically ka hōʻike ʻana i nā pale metala, ka piʻi ʻana o ke kaumaha o ka prosthesis, ka hiki i ka ʻono metala, a me nā hopena maʻi i nā metala ua alakaʻi i ka ka hoʻolauna ʻana i nā mea thermoplastic he nui, e like me ka nylon a me nā resins acetal, i loko o ka hana lapaʻau. I nā makahiki i hala iho nei, he prosthetic ʻē aʻe Ua hoʻohana maikaʻi ʻia nā mea (PEEK) i ka lāʻau lapaʻau, ʻoi aku hoʻi ma nā lāʻau lapaʻau. ʻO ka mea PEEK i hoʻololi ʻia me ka 20% ceramic filler he kiʻekiʻe polymer hana me ka biocompatibility kiʻekiʻe, nā waiwai mechanical maikaʻi, kiʻekiʻe pale wela a me ka paʻa kemika. Mahalo i kona elastic modulus o 4 GPa, he elastic e like me ka iwi, e hoemi ana i ke kaumaha i laweia i ka abutment. Hoʻohui ʻia, hāʻawi ke kala keʻokeʻo o ke kiʻi PEEK i kahi ʻokoʻa ʻoi aku ka maikaʻi ma mua o nā hōʻikeʻike metala kuʻuna. ʻO nā pono ʻē aʻe o ʻO kēia mea polymer ka hoʻopau ʻana i nā hopena maʻi a me ka ʻono metala, kiʻekiʻe polishing maikaʻi, haʻahaʻa plaque affinity a me ka maikaʻi abrasion kū'ē.

• PEEK uea orthodontic

Hiki ke hoʻohana ʻia ka PEEK ma ke ʻano he uea orthodontic aesthetic. Hoʻohālikelike ʻia me nā mea ʻē aʻe polymers, e like me ka polyvinylsulfone (PES) a me ka polyvinylidene fluoride (PVDF), Hāʻawi nā uea orthodontic PEEK i ka ikaika orthodontic kiʻekiʻe. Orthodontic like Ua loaʻa nā ikaika i ka hoʻohālikelike ʻia me ka titanium-molybdenum a me ka nickel-titanium uwea.

• PEEK implants

I nā makahiki 1960, ua hana nui ʻia nā implants niho intraosseous me ka metala maʻemaʻe titanium a me ka titanium alloys. ʻOiai ua kākoʻo ʻia nā implants titanium e a ka nui o nā hōʻike hoʻokolohua hoʻokolohua a me nā noiʻi lapaʻau, aia nō kekahi mau pilikia i kā lākou hoʻohana lapaʻau. ʻO kekahi o ka sensitization o titanium. ʻO ka lua, ke hoʻohālikelike ʻia me ka ʻiʻo iwi iwi, ka modulus elastic o He kiʻekiʻe loa ka titanium, hiki ke hoʻoponopono hou a nalowale paha i ka iwi iwi. Ke kolu, metala implants nele malamalama transmittance, e pili ana i ka helehelena.

I ka makahiki 1998, ua hoʻokumu ka hui Pelekane ʻo Invibio i nā implants PEEK. Me ka hiki ʻana mai o ka PEEK implants pāʻoihana, pili noiʻi ua mahuahua malie. PEEK a ʻO kāna mau mea i hoʻololi ʻia he mau waiwai maikaʻi. Manaʻo kekahi poʻe naʻauao ʻo PEEK Hiki i nā implants ke pale i ka hiki ʻana mai o nā hopena pale koʻikoʻi, a hiki nō hoʻololi i nā implants metala i ka ʻoki plastik, ka hōʻeha trauma a me nā kahua ʻē aʻe.

1. Biocompatibility - Ua hōʻoia ʻia ka biocompatibility o PEEK, me mau haʻawina e hōʻoia ana i kona non-toxicity. ʻOiai ma hope o ka hoʻohana ʻana i nā tausani o nā mea maʻi, ʻo PEEK kahi koho maikaʻi loa i hoʻohālikelike ʻia i nā metala, hiki ke kumu nā hopena maʻi a hiki i ka 15% o ka heluna kanaka.

Hoʻohana ʻia nā mea PEEK i nā implants spinal, nā mea hoʻoponopono trauma, hip a pani kuli, a me na mea lapaau e ae. I kekahi hihia, ʻaʻohe nīnau e pili ana i ka palekana o PEEK ma ke kino.

2. Mechanical waiwai - PEEK loaʻa ka ikaika-a-kaumaha ratio, he mea koʻikoʻi loa ia no nā implants niho a me nā mea hana. Hoʻohālikelike ʻia me metala, ʻoi aku ka māmā a me ka ʻoluʻolu o PEEK no ka mea maʻi. Hoʻohui kēia i ka hōʻoluʻolu ʻAʻole hoʻi e hoʻololi i ka lōʻihi, no ka mea hiki i ka PEEK ke kū i ka abrasive a nā ikaika compressive me ka nalowale ʻole o kona kūpaʻa. ʻAʻole hiki ke pale ʻia kēia polymer ʻino a hoʻopaʻa i ka makū ma kahi liʻiliʻi, no laila hiki ke hoʻomau no nā makahiki me ka hoʻohaʻahaʻa ʻole o ka hana.

3. Mākaukau mīkini-Ke hilinaʻi nei nā kauka niho i ka hoʻolālā kōkua kamepiula (CAD) a me ka mīkini (CAM) ʻoi aku ma mua o ka manawa, a maikaʻi ʻo PEEK no kēlā. He mea nui ʻO ka hiʻohiʻona o nā mea hana niho o kēia manawa ke kūlike pololei me ke anatomi o ka mea maʻi, a CAD/CAM pono e hana ia. Mālama kēia e hoʻomaha ka mea hana ʻoluʻolu, hana maikaʻi loa a hoʻohana ʻia no ka lōʻihi o ka hiki.

Inā hana ʻia ʻo PEEK e like me nā kikoʻī o ka mea hana, e paʻa ia waiwai ma hope o ka wili ʻana. ʻO kēia paʻa i hoʻohui ʻia e ʻae i ka hiki ke maʻalahi i ka wā o ka hoʻolālā ʻana a maʻalahi i nā niho niho e hoʻolako i kā lākou mau maʻi me nā mea hana maʻamau.

ʻO ka maʻalahi o ka PEEK me nā ʻano CAD/CAM ʻo ia hoʻi ke hiki ke hana ʻia wikiwiki a mau. I ka pōkole, hiki ke hana ʻia nā mea PEEK me ka hilinaʻi a wikiwiki.

4. Hoʻololi - He lōʻihi kēia polymer hana kiʻekiʻe akā ʻaʻole ʻoʻoleʻa. I ka manawa ʻaʻole i hoʻopiha ʻia, hāʻawi ia i kahi modulus e like me ka iwi cortical, e hana ana i ka PEEK i ikaika, mea niho ma'alahi. Me kona maʻalahi, manaʻo maoli ka PEEK i ka waha a mau loa ka elastic ma hope o nā makahiki o ka nahu ʻana a me ka nau ʻana. Nā lako niho pono e mālama i ko lākou ʻano me ke kaomi mau, a ʻo PEEK kekahi o nā polymers maikaʻi loa no kēia.

5. Radiolucent - ʻelua ka modulus like me ka iwi a me ka radiolucency o PEEK nā waiwai i hoʻomaka mua i ka manaʻo o nā mea noiʻi lapaʻau i PEEK, a noho mau ia i kekahi o nā waiwai koʻikoʻi o ka polymer. I kēia mau lā makahiki, noiʻi ma PEEK niho implants ua hōʻike i ka mea i loaʻa hiki nui ma keia kahua.

He waiwai waiwai ka radiolucency o PEEK ke hoʻohana ʻia ka mea i loko kekahi kaʻina hana implantation. Ke hoʻokomo ʻia, ʻaʻole ʻike ʻia ka polymer hoʻopilikia i nā kiʻi X-ray, CT a i ʻole MRI. No ka mea, he mea nui ka X-ray no ka niho ʻO ka maʻi maʻi, ʻo ka opacity o PEEK i ke kiʻi e hōʻoia i hiki i nā niho ke hana i kā lākou ka hana o ka nānā ʻana i ke olakino maʻi. Ma kahi o ka radiolucency kiʻekiʻe o PEEK ʻike ʻia he mea keakea, hiki ke hoʻonui ʻia ka polymer me nā mea hoʻohui e like me ka barium sulfate e hana i ka ʻokoʻa maikaʻi.

6. Aesthetics - E like me ka PEEK hiki ke hana maʻalahi i nā kiʻi maʻamau, hiki ke kala like me ka mea maʻi. ʻO ka ʻokoʻa, pinepine nā metala hikiʻole ke hūnā i ka waha, he mea hopohopo ia no nā maʻi.

ʻO PEEK kahi mea niho e hui maʻalahi i ka waha no kona kala hiki ke hoʻololi i ka wā o ka hana. Hiki ke hana maoli ʻia nā niho niho piha, hōʻoia i ka poʻe maʻi e ʻōlelo, ʻakaʻaka a ʻai me ka hilinaʻi.

7. ʻAi ʻole - ʻO kekahi pilikia me nā mea metala ʻo ia ka hāʻawi ʻana he ʻono metala i nā maʻi he nui. ʻAʻole ia he pilikia olakino, akā he pilikia mau ka huhū no nā poʻe maʻi makemake ʻole e hoʻomanaʻo ʻia he mau niho niho ko lākou a i ʻole nā ​​papa.
