What is the maximum projection (in cm) dermal fillers can provide for chin and jaw wings? Which one is the best and safest?

There is no way to tell since every individual is different. To correct soft tissue deficit, fillers are a good option but to correct a bony deficit, you need to consider facial implants which can provide predictable and permanent correction and projection.

 Hi, I can't give you mm's of augmentation in the chin and jaw line using fillers versus implants however I have performed many using eacvh and feel that roughly 60% or so of the augmentation achieved with an implant can be achieved using Radiesse for the chin and jaw line.  Hope this helps.
