2.} Cov Khoom Siv Khoom Siv

Acrylic Cov Hniav

Kev sib xyaw: ua los ntawm PMMA (polymethyl methacrylate), ib feem siv hluav taws xob polymer hauv kev kho hniav {}}

Lub zog & durability:

Lub Zog Faj: 60-80 MPA

Nquag mus rau cov pob txha lov hauv cov tub rog hnyav

Nyhav hnav ris tsho, cuam tshuam haum thiab ua haujlwm nyob rau lub sijhawm

Aesthetics:

Tuaj yeem ua xim kom phim cov hniav ntuj, tab sis muaj tsawg translucency thiab xim ruaj khov dua li zirconia

Raug rau kev yellowing lossis discoloration thaum lub sijhawm

 

Puv-ka cov choj zirceges (siv peb zirconia blocks)

Kev sib xyaw: ua los ntawm high-purity zirconium dioxide (zro₂)

Lub zog & durability:

FLEXURAL LUB ZOG: Txog 1200 MPA

Koj tsis kam tiv taus chipping thiab pob txha lov

Proven longevity >10 xyoo nrog kev tu kom zoo

Aesthetics:

Kev Ua Kom Zoo Tshaj Plaws Cov Hniav

Tau tshaj vita 16 xim system rau qhov tseeb ntxoov ntxoo txuam

Tswj hwm xim stability nyob rau lub sijhawm
