Composite resin is injected into the hole and treated to a blue wavelength light to dry or cure. The patient must be still through the process which only takes a few minutes once the soft composite is placed in the tooth. The material used for a composite posterior restoration is a ...
Epoxy resins can be altered and impregnated into the fiber and be in what is called a B-stage. This is how prepregs are created. With epoxy prepregs, the resin is tacky, but not cured. This allows layers of prepreg materials to be cut, stacked, and placed in a mold. Then, with th...
HPL is a manufactured composite material. It consists of printed decoration paper fused to multiple sheets (6-8 pieces) of Kraft paper saturated with a synthetic thermosetting resin. A curing or thermosetting process combines the sheets using heat andhigh pressure(more than 1,000 PSI) to form ...
The patellar ligamentweight-bearingBKprosthesis is the earliest product of modern prostheses. It mainly uses the patellar ligament as the mainweight-bearingpart. The resin composite material used is laminated and vacuumized to form theprosthetic socket, so the metal knee joint hinge and upper thigh...
