How much width can be added to jaw through bimax realistically? (no implants)

very little

but ccw makes the jaw appear wider front the front

Half an inch on both gonions is asking too much then? How about lowering the gonions is it possible?

The amount of ramus widening you can get with bimax is heavily case dependent. It is reliant on the shape of your condyles and this can only be ascertained by a maxillofacial surgeon looking at your CT scan. However, I've never heard a case where 0.5in could be added to both sides. Nonetheless, a little goes a long way with ramus widening.

I think it also depends on how much you advance the lower jaw

Is there much benefit if one is undergoing jaw implants in the future? Could you not just request slightly more lateral projection from an implant or is there some added benefit to ramus widening that makes it worth the cost?

Jaw implants and ramus widening in bimax address different aesthetic issues and are not interchangeable.

It depends where you were meaning to put that lateral projection, but in any case it would be clunky to try to recreate what ramus widening in bimax does with a jaw implant.

What happens in ramus widening is the angle at which your gonions transition into your chin is laterally opened up (mentomandibular angle). The gonial angle and jaw width, as in bigonial distance, remain the same. Jaw implants are typically used to increase bigonial distance, decrease gonial angle, and add height to the mandible. It depends on the bone cut but ramus widening moves outward a much larger part of the mandibular body than implants typically cover.

One reason why some jaw implants look uncanny is because they end up with a bigonial distance that is too big for their gonial and/or mentomandibular angles. It's not good to have your jaw too wide and then have it move into the chin at too dramatic an angle. There is some harmonic sweet spot of all these angles; I have no idea what it would be. Though it's hard to say when it's right, but it's easy to say when it's wrong.
