I have healthy teeth but want to change the shape. What procedures would you suggest? (photos)

My problem is that I don't like the shape of my teeth! And I am willing to pay a lot to have them fixed. I talked with Straumann- dental clinic, and they say they don't do implants on healthy teeth, only patients who are missing teeth. Is this correct? I am thinking about braces. But i'm afraid that it will not give the drastic change I want. I have 2 picture to show what kinda teeth I want! I like when the teeth are slightly bend backwards, kinda vampire look. I need advice on what to do??
