Nerve Repair. Injuries to the inferior alveolar nerve (IAN) and the lingual nerve are relatively uncommon events. However, there are certain routine surgical and non-surgical procedures that have the potential, albeit small, for injuring these neural structures.
Rubidium hydroxide is a chemical compound. It is composed of rubidium and hydroxide ions. Its chemical formula is RbOH. It is a very strong base. It can eat through glass. It is made by dissolving rubidium oxide in water. It causes immediate burns to the skin.
Platinum-iridium alloy. Platinum-iridium alloys are alloys of the platinum group precious metals platinum and iridium. Typical alloy proportions are 90:10 or 70:30 (Pt:Ir). These have the chemical stability of platinum, but increased hardness. The Vickers hardness of pure platinum is 56 HV while platinum with 50% of iridium can reach over 500 HV.
