Kune vatengi vanotsvaga yakaderera maMOQ uye yakakwira zvigadzirwa zvakasiyana, Multispecialty Suppliers inopa yakaderera MOQ kugadzirisa, kupera-kusvika-kumagumo zvigadziriso zvekugadzirisa, uye akawanda-mapoka ekutenga, achitsigirwa neindasitiri yavo yakapfuma uye ruzivo rwesevhisi uye kunzwisisa kwakasimba kwemafambiro echigadzirwa chiri kubuda.
I. Chii chinonzi synthetic bone replacement?
Synthetic bone inotsiva ibhonzo inotsiva zvinhu zvinogadzirwa kuburikidza neyakagadzirwa synthesis kana makemikari nzira uye inonyanya kushandiswa kugadzirisa kukanganisa kwemapfupa. Zvishandiso zvepakati zvinosanganisira hydroxyapatite, β-tricalcium phosphate, uye polylactic acid, uye ine zvinotevera hunhu:
Material Types
Inorganic zvinhu, zvakadai sehydroxyapatite (yakafanana mukuumbwa kune pfupa remunhu) uye β-tricalcium phosphate, inopa zvimiro zvakagadzikana uye biocompatibility yakanaka.
Zvishandiso zvepolymer, senge polylactic asidhi uye polyethylene, zvinogadziriswa uye zvishoma nezvishoma zvakanyura mumuviri, zvichibvisa kudiwa kwekuvhiya kwechipiri.
Clinical Applications
Iwo anonyanya kushandiswa kuzadza mapfupa akaremara kana kupa tsigiro yechimiro, seyakagadzirwa pfupa poda mualveolar bone augmentation oparesheni. Zvinhu izvi zvinofanira kusarudzwa zvichienderana nemamiriro ezvinhu chaiwo omurwere. Semuyenzaniso:
Dental implants: Zvinhu zvakadai sehydroxyapatite zvinowanzoshandiswa kusimbisa alveolar bone kugadzikana.
Kugadziriswa kwekutsemuka: Kukanganisa kunozadzwa nesimbi scaffolds kana bioceramics.
Zvakanakira uye Zvakaipa
Zvakanakira zvinosanganisira kudzoreka kwegadziriro yegadziriro uye kubviswa kwekudiwa kwezvinhu zvekuwedzera. Kuipa kunosanganisira kushomeka kwebioactivity uye kudiwa kwekusanganiswa nezvimwe zvinhu (senge autologous bone) kuwedzera kushanda.
II.Mabhonzo anoisirwa mapfupa aripo here?
Bone transplantation inogoneka. Bone transplantation inzira yakajairika yekuvhiya mukurapa, inonyanya kushandiswa kugadzirisa kukanganisa kwemapfupa kunokonzerwa nekushungurudzika, kutapukirwa, mamota, kana kuremara kwekuzvarwa, uye kubatsira kudzorera basa remapfupa. Bone masosi ekutapurirana anosanganisira autologous bone (kubva kune dzimwe nzvimbo dzemuviri wemurwere), allogeneic bone (yakapihwa bhonzo), uye yakagadzirwa bhonzo zvinhu. Chisarudzo chaicho chinoenderana nemamiriro emurwere.
I. Mhando dzeBone Transplantation
1. Autologous Bone Transplantation
Nheyo: Bone rinokohwewa kubva kumapfupa emurwere asingaremi (akadai seilium kana fibula) uye anosimwa kunzvimbo yakakanganiswa.
Zvakanakira: Hapana kurambwa, kupora kwakanyanya.
Zvakaipa: Nzvimbo yevanopa inogona kurwadza kana kutapukirwa, uye mapfupa emapfupa ane mashoma.
2. Allogeneic Bone Transplantation
Nheyo: Yakapihwa pfupa tishu (yakaomeswa uye yakabviswa mishonga) inoshandiswa.
Kushandisa: Kuremara kwemapfupa makuru kana kusakwana autologous bone.
Njodzi: Kugona kurambwa kana kutapurirana kwechirwere (kunyanya kushomeka).
3. Artificial Bone Materials
Material Types: Hydroxyapatite, bioceramics, etc. Features: Yakasimba plastiki, asi simba remagetsi uye biological activity inogona kunge yakaderera kupfuura pfupa rechisikigo.
II. Zvishandiso zveBone Transplantation
Trauma repair: Semuenzaniso, kuputsika kwakanyanya kunoguma nekuremara kwemapfupa asingakwanisi kuporesa ega.
Bone tumor resection: Yekuzadza bhonzo mushure mekubviswa bundu.
Spinal fusion: Kuti skeletal kugadzikana kuwedzeredzwa mushure mekuvhiyiwa kwe lumbar spine.
Congenital deformity kugadziriswa: Somuenzaniso, congenital tibial pseudarthrosis.
