Rau cov neeg yuav khoom nrhiav cov MOQ qis thiab cov khoom lag luam siab, Multispecialty Suppliers muab MOQ qis customization, kawg-rau-kawg logistics kev daws teeb meem, thiab ntau yam kev yuav khoom, txhawb nqa los ntawm lawv cov kev lag luam nplua nuj thiab kev pabcuam thiab kev nkag siab zoo ntawm cov khoom lag luam tawm tshiab.
I.Dab tsi yog kev hloov cov pob txha hluavtaws?
Synthetic pob txha hloov yog cov pob txha hloov cov ntaub ntawv tsim los ntawm cov khoom siv hluavtaws lossis cov tshuaj siv tshuaj thiab feem ntau yog siv los kho cov pob txha. Cov ntaub ntawv tseem ceeb muaj xws li hydroxyapatite, β-tricalcium phosphate, thiab polylactic acid, thiab muaj cov yam ntxwv hauv qab no:
Hom khoom
Inorganic cov ntaub ntawv, xws li hydroxyapatite (zoo ib yam li nyob rau hauv muaj pes tsawg leeg rau tib neeg pob txha) thiab β-tricalcium phosphate, muaj cov qauv ruaj khov thiab zoo biocompatibility.
Cov ntaub ntawv polymer, xws li polylactic acid thiab polyethylene, yog biodegradable thiab maj mam nqus hauv lub cev, tshem tawm qhov kev xav tau ntawm kev phais thib ob.
Kev siv tshuaj kho mob
Lawv feem ntau yog siv los sau cov pob txha tsis xws luag lossis muab kev txhawb nqa, xws li cov pob txha pob txha hauv cov pob txha alveolar augmentation phais. Cov ntaub ntawv no yuav tsum raug xaiv raws li tus neeg mob qhov xwm txheej tshwj xeeb. Piv txwv li:
Kev cog hniav: Cov khoom siv xws li hydroxyapatite feem ntau yog siv los txhim kho cov pob txha alveolar.
Kev kho pob txha: Cov kev puas tsuaj yog sau nrog cov hlau scaffolds lossis bioceramics.
Qhov zoo thiab qhov tsis zoo
Qhov zoo muaj xws li txheej txheem kev npaj tswj tau thiab tshem tawm qhov xav tau ntawm cov khoom siv ntxiv. Qhov tsis zoo muaj xws li bioactivity tsis muaj zog thiab xav tau kev sib xyaw nrog lwm cov ntaub ntawv (xws li pob txha autologous) los txhim kho kev ua tau zoo.
II.Puas muaj pob txha hloov?
Kev hloov pob txha yog ua tau. Kev hloov pob txha yog ib txoj kev phais ntau hauv cov tshuaj, feem ntau yog siv los kho cov pob txha tsis xws luag los ntawm kev raug mob, kab mob, qog, los yog qhov tsis xws luag, thiab pab kho pob txha ua haujlwm. Cov pob txha rau kev hloov pauv muaj xws li pob txha autologous (los ntawm lwm qhov chaw ntawm tus neeg mob lub cev), pob txha allogeneic (pob txha pob txha), thiab cov khoom siv pob txha. Qhov kev xaiv tshwj xeeb yog nyob ntawm tus neeg mob tus mob.
I. Hom Kev Hloov Pob Txha
1. Autologous pob txha hloov
Lub hauv paus ntsiab lus: Cov pob txha raug sau los ntawm tus neeg mob tus kheej cov pob txha uas tsis hnyav (xws li ilium lossis fibula) thiab hloov mus rau qhov chaw tsis xws luag.
Qhov zoo: Tsis muaj kev tsis lees paub, kev kho mob siab.
Qhov tsis zoo: Qhov chaw pub dawb yuav mob lossis kis tau, thiab cov pob txha pob txha muaj tsawg.
2. Allogeneic pob txha hloov
Lub hauv paus ntsiab lus: Pub dawb cov ntaub so ntswg (sterilized thiab deimmunized) yog siv.
Daim Ntawv Thov: Cov pob txha loj lossis cov pob txha autologous tsis txaus.
Kev pheej hmoo: Muaj peev xwm tsis lees paub lossis kis kab mob (tsawg kawg nkaus).
3. Khoom siv pob txha pob txha
Cov khoom siv: Hydroxyapatite, bioceramics, thiab lwm yam Nta: Cov yas muaj zog, tab sis cov neeg kho tshuab lub zog thiab cov khoom siv roj ntsha tuaj yeem qis dua cov pob txha ntuj.
II. Kev siv cov pob txha Transplantation
Kev kho mob: Piv txwv li, kev puas tsuaj loj uas ua rau cov pob txha tsis zoo uas tsis tuaj yeem kho lawv tus kheej.
Pob txha qog resection: Rau pob txha txhaws tom qab qog resection.
Spinal fusion: Rau skeletal stability li nram qab no lumbar spine phais.
Congenital deformity kho: Piv txwv li, congenital tibial pseudarthrosis.
