Ayn Ayn Seen says: If someone gets artificial teeth and leaves gaps between them.

Is this action included in the hadith about the curse mentioned by the Prophet ﷺ when he said: and those who create gaps between their teeth for beauty, changing the creation of Allah?

The hadith refers to natural teeth.

That have no defect, but she creates gaps between them.

She makes gaps between them for the sake of beauty, as she claims.

This is what the Prophet ﷺ cursed.

Whoever does this, as for artificial teeth, I do not think they are included.

In this, yes.
