Are metal spokes showing at front of teeth necessary on partial denture for bottom teeth?

I had a fitting for a partial denture recently- 2 back bottom teeth on one side and 1 on the other. Metal. And there are two metal spokes sticking out at front of my teeth, one on each side of my mouth, which I am told are necessary to hold it in place - is this correct? I am conscious that they may show and they seem terribly ugly. Or maybe this is a cheap and nasty version?
