Pec Implants for a square(r) look?

Thank you for your question.Some pictures would be useful if you had a chance.All implant will accentuate your original shape and it is usually what we recommend.  The pec implants must fit in the size of your own chest under your muscles.That being said, the large square-type of implant will change your more oval/triangular shape into a more square one.  As for the cleavage, it has to do with the amount of safe midline dissection your plastic surgeon will do.
The problems with the square one is when you move your arms up, the pectoralis also moves up and becomes almost vertical, exposing the outer-lower "corners" of a square implant (implants become encapsulated and fixated to the ribcage and won't move with the muscle).  This issue is much less important with the oval implants that tend to imitate better the outer edge of the pectoralis muscles.
Hope this helps!
Kind regards,
Dr. Marc DuPere, Aesthetic, cosmetic and reconstructive plastic surgeon
