Anesthesia
The procedure can be done awake or asleep. I typically recommend performing the procedure under local anesthesia, especially if being done alone, because I find those areas easy to numb. This avoids the risk and expense of general anesthesia. A mild oral sedative (such as lorazepam) is prescribed for anxiety prior to the procedure
Implant selection
I exclusively use the Implantech conform implant. No two chin bones are exactly the same, I find that the conform technology allows the implant to contour the existing chin bone a lot better due to its semirigid nature. An older rigid implant will have more predefined shape that they will not settle down and sometimes create a step off where it doesn’t sit on the bone.
