This is actually a very complex question. It really boils down to why is it crooked in the first place. Below I will list the possible reasons for crookedness and what I would recommend to fix it:1) Surgical Swelling- if you are 6 months or less from the surgery there still may be some postsurgical swelling that causes it to look uneven. Wait until you see the final results. It may be much less noticeable than you think in the end. 2) Malplacement by the physician- if the implant was placed such that one side is horizontally rotated around the side (the midline of the implant is not lined up with your midline) or it has rotated down below the margin or edge of your jaw bone, the only way it can be fixed is to go back and reposition it. If this is an Implantec solid silicone implant, then the risk of infection is low as there are no holes or gaps where the bacteria can collect. While the infection risk is higher than when originally done, it is still relatively low if it is done under completely sterile surgical conditions (hopefully the way it was done the first time). 3) Crookedness is the result of a pre-existing crooked jaw or chin- Some asymmetry to the original bone can be corrected by simply filing off a high point of bone and evening out the surface. However, other types of asymmetries are more difficult or even not possible to fix. Looking closely at the before pictures should help you figure this out. While there may be some hope to move it with massaging, I think that is unlikely. I guess it is worth a try and won't hurt anything, but I would still make plans for what you are going to do if it doesn't work. Best of luck. Let us know if we can help.
