Hypersensitivity reaction in peri-oral skin associated with metal dental implants

The aim of this case study was to present the rare entity of hypersensitivity reaction in perioral skin which was associated with metal dental implants. A 69-year-old male patient treated with complete upper and lower implant-supported overdentures. The patient was ended up with extra-oral blackish pigmentations on his skin of the entire neck region four months after placement of implants. This presentation seemed to be suspected association of allergic reactions to metal dental implants in an otherwise healthy individual. Even though titanium considered as a biocompatible metal for using human surgical procedures, there are some instances which can be allergic for titanium and other associated elements. Therefore, it would be better to perform the hypersensitivity reaction test prior to introduce the metal devices for the patients.
