What if my tooth implant cannot be done? (Photo)

So, I'd scheduled my my from teeth implant it because my crown tooth has broken from the gum lines. But, when the doctor had taken 3D Scan, he found out that I have an extra tooth above the tooth that he supposed to extract it in order to put the titanium implant in. He suggested not to take the broken tooth out and just simple do the bridge instead. It's my central incision.
