Poly(methyl methacrylate) - Wikipedia

Poly(methyl methacrylate) (PMMA), also known as acrylic or acrylic glass as well as by the trade names Crylux, Plexiglas, Acrylite, Lucite, and Perspex among several others (see below), is a transparent thermoplastic often used in sheet form as a lightweight or shatter-resistant alternative to glass. The same material can be.

From each group, six lateral tibia halves were weighed, chilled with liquid nitrogen, crushed into fragments, and pulverized in a sterile bone mill.

Polymethylmethacrylate-induced release of bone-resorbing factors .

A pseudomembranous structure that has the histological characteristics of a foreign-body-like reaction invariably develops at the bone-cement interface in the proximity of resorption of bone around aseptically loosened cemented prostheses. This study was an attempt to implicate polymethylmethacrylate in this resorptive.
