Antiquities Minister Mamdouh el-Damaty says the mask was restored to its place at the Egyptian Museum on Wednesday evening.
A German-Egyptian team began the restoration work in October after a museum employee knocked the beard off during work on the relic`s lighting, after which workers tried to reattach it with epoxy.
The mask is arguably the best-known piece in the museum, one of Cairo`s main tourist sites.
The museum is one of Cairo’s main tourist sites, but in some areas, ancient wooden sarcophagi are unprotected from the public, while linen burial shrouds, mounted on walls, crumble from behind panels of glass.
The vast majority of its rooms lack climate control and the roof has leaked in recent years.
