Dental implants v. Bridges

Hello, I am a 48 year old male, as I am need of a second opinion and I am need of full mouth restoration, 98% in implant; as I was advised by my Dentist that its recommend to get the bottom front teeth, bridged/crowned than implanted. She said that having implants on the bottom, as I will have implants on the top, might cause a collision while chewing food; considering that they are not my teeth. By having a bridge/crown on the bottom front instead will prevent this collision, as I know that the bottom front teeth that is just grinded down is mine; but supported with a bridge and a crown.
Can please advise your comments, if what this Dentist said me actually is true.
