Our patients often are under the impression that implants and implant crown take a long time to complete.  You have to wait for the bone to heal but in most cases the crown can be placed in about 3 months after the implant is placed.  With some implant systems this can be shortened to 6-8 weeks.  You must realize that bone takes a certain amount of time to heal.  If you broke your arm you would be in a cast 2 months waiting for the bone to heal.  The jaw is no different.  In many cases however the patient is not left without a tooth for this period of healing.  There are many different options available to provide a temporary tooth during this time.   There are situations where implant healing may take longer depending on the quality and quantity of bone.
