Mpempe profaịlụ dị ala dị ala nwere akụkụ na profaịlụ efere sara mbara na-enye ihe ọ bụla enweghị ike ime.Dị n'ogologo ahaziri nke ukwuu.
Uru nke skru titanium alloy:
1. Ike dị elu.Njupụta nke titanium bụ 4.51g/cm³, dị elu karịa nke aluminom ma dị ala karịa nke ígwè, ọla kọpa na nickel, mana ike dị elu karịa nke ọla ndị ọzọ.Ịghasa nke titanium alloy mere bụ ìhè na ike.
2. Ezigbo nguzogide corrosion, titanium na titanium alloy n'ọtụtụ mgbasa ozi kwụsiri ike, a na-etinye kposara alloy titanium n'ọtụtụ ebe na-emebi emebi ngwa ngwa.
3. Ezigbo okpomọkụ na-eguzogide na obere okpomọkụ.
4. Ndị na-abụghị magnetik, ndị na-adịghị egbu egbu. Titanium bụ ígwè na-abụghị nke magnet na a gaghị eme ka ọ bụrụ magnetized na nnukwu oghere magnetik. Ọ bụghị naanị na-adịghị egbu egbu, ma nwee ezigbo ndakọrịta na ahụ mmadụ.
5. Strong mgbochi damping arụmọrụ.Tụnyere ígwè na ọla kọpa, titanium nwere ogologo oge vibration attenuation oge mgbe n'ibu vibration na electric vibration.This arụmọrụ nwere ike ji mee ihe dị ka n'iji ya gee ntị ndụdụ, vibration components nke ọgwụ ultrasonic grinders na vibration nkiri nke elu audio ụda okwu. .
Nhazi eriri maka mmalite ịghasa ngwa ngwa yana ike ntinye dị ala.Nhọrọ sara mbara nke efere na ntupu, gụnyere mastoid na meshes nwa oge, na oghere burr maka shunts.

A na-ejikarị skru eme ihe n'ịwa ahụ ọkpụkpụ iji mpikota onu ebe mgbawa ahụ, dozie efere ahụ n'ọkpụkpụ, ma dozie ọkpụkpụ ahụ n'ime ma ọ bụ nke dị n'èzí. dibia bekee.
Otú ọ dị, ka ụda ike na-abawanye, ihe nkedo ahụ na-enweta ike kachasị ike (Tmax), mgbe ahụ na-ebelata ihe nkedo na-ejide ọkpụkpụ na ọkpụkpụ ma dọpụta ya ntakịrị anya. Pull-out force (POS) bụ esemokwu ahụ. iji gbagọọ ihe nkedo ahụ n'ọkpụkpụ.A na-ejikarị ya eme ihe dị ka parameter iji tụọ ike njide nke screw. Ka ọ dị ugbu a, mmekọrịta dị n'etiti oke ike na ike ndọpụ ka amabeghị.
N'ụlọ ọgwụ, ndị dọkịta na-awa orthopedic na-ejikarị ihe dịka 86% Tmax tinye ihe nkedo ahụ. Otú ọ dị, Cleek et al.chọpụtara na ntinye nke 70% Tmax na tibia nke atụrụ nwere ike nweta POS kachasị elu, na-egosi na enwere ike iji ike torsion dị ukwuu mee ihe na ụlọ ọgwụ, nke ga-ebelata nkwụsi ike nke nhazi.
Nnyocha e mere n'oge na-adịbeghị anya banyere humerus na cadavers mmadụ site na Tankard et al.chọpụtara na enwetara POS kacha elu na 50% Tmax. Isi ihe kpatara ọdịiche dị na nsonaazụ ndị a dị n'elu nwere ike ịbụ enweghị nkwekọrịta nke ihe atụ ndị a na-eji na ụkpụrụ nha dị iche iche.
Ya mere, Kyle M. Rose et al.site na United States tụrụ mmekọrịta dị n'etiti Tmax dị iche iche na POS site na screws tinye n'ime tibia nke cadavers mmadụ, ma nyochaakwa mmekọrịta dị n'etiti Tmax na BMD na ọkpụkpụ cortical. Enwere ike nweta POS kachasị na nke yiri ya na 70% na 90% Tmax na screw torque, na POS nke 90% Tmax screw torque dị nnọọ ukwuu karịa nke 100% Tmax.Enweghị ọdịiche dị na BMD na cortical cortical dị n'etiti ìgwè tibia, ọ dịghịkwa njikọ dị n'etiti Tmax na nke abụọ dị n'elu. Ya mere, na omume ụlọ ọgwụ, dọkịta na-awa ahụ ekwesịghị ime ka ịghasa ahụ na-eji ike kachasị elu, ma na-eji ntakịrị ihe mgbagwoju anya. erughị Tmax.Ọ bụ ezie na 70% na 90% Tmax nwere ike nweta POS yiri nke ahụ, a ka nwere ụfọdụ uru na-emebiga ihe ókè nke ịghasa, ma torque agaghị agafe 90%, ma ọ bụghị ya ga-emetụta mmetụta nhazi.
