Taper is the slotted part of head which fits into trunnion of stem; corrosion of this part is called Taperosis (Fig. Corrosion can be defined as the graded degradation of materials by chemical or electrochemical attack. Even though titanium alloys are exceptionally corrosion resistant because of the stability of the TiO 2 layer, they are not inert to corrosive … Therefore, corrosion has been considered as the most important factor in the selection of metallic materials, hence it deserves special emphasis and must be evaluated in ever-changing oral environment. Corrosion can be defined as the graded degradation of materials by chemical or electrochemical attack. The effects of the dental alloys on the oral environment have the capabilities for producing local, remote, or systematic changes that may be short term, long term, or repetitive (tissue sensitization) in nature (Ref 8). This section discusses the corrosion behavior of metals and alloys used in dentistry. Ion Patrascu, Vlad Gabriel Vasilescu and Stefan Milicescu (February 20th 2014).
