(Adapted from Guy AG: Elements of Physical Metallurgy, ed 2, Reading, MA, Addison-Wesley, 1959.) Dental implants in current widespread clinical use are manufactured from CP (commercially pure) titanium or Ti-6Al-4V, and some implants have a thin bioceramic surface coating (typically hydroxyapatite, the principal inorganic constituent of bone and tooth structure). Metallurgy has been leading human civilization from time immemorial. It is important to note that pure metalls have a specific bp mp. The reducing flame is best obtained by placing the blowpipe nozzle in the edge of the flame; whilst the oxidising flame duced, when the nozzle is ptished.
