You're talking about dentures and not implants, right? Generally the sensory feedback you get from chewing is from the teeth transmitting forces to the periodontal tissue, not actually feeling forces in your teeth through the enamel.

Dentures disupt this process not because they don't have nerves, but because they totally change the way forces are transmitted to the periodontal tissue. I believe that root-canaled teeth and bone-borne dental implants still allow force feedback like healthy teeth do.
