Timeframe Of Intraoral Chin Implant Wound Healing?

Phillipp,  it sounds like at least one layer of sutures have partially come apart (dehisced).  This is usually not a problem provided that the closure your surgeon performed was in layers, including a "water tight" closure of periosteum around the implant.  In most cases, this wound will heal slowly over the next 2 weeks.  Your job is to make sure you are very gentle with it and do not allow any food to get trapped in that area.

Avoid eating foods you bite with your incisors for the next two weeks (no apples, sandwiches, etc), take care brushing your teeth, and rinse your mouth gently after each meal.  Contact your surgeon as well so you can be on some antibiotics until the wound heals completely.

I hope this helps!

The intraoral incision should be closed within a week. If there are gaps then check with your surgeon ASAP for examination. Most of the time there are more than one layer of closure, however the wound need some care.
