What is one stage surgery? Two stage surgery? Immediate function?  One stage surgery refers to the placing of the implant with a healing cap.  The top of the healing cap is exposed.  This works but there are circumstances when it is to be avoided. Two stage surgery means the implant is placed but covered with your gum tissue.  At a second surgery the implant is uncovered and a healing cap is placed.  The tissue is allowed to heal before restoring with a crown.  Immediate function means the implant is placed and it is restored with a temporary crown that day.  This is usually done when aesthetics are important, such as a front tooth fractures beyond repair and a replacement is needed immediately.
