Fig.4 One end of an abutment  is inserted into the hole of the implant.  The other end of the abutment (A) passes through the gums (T/L), sticks into the mouth and receives a crown. 

There are two types of gums around the abutment.  The one immediately next to the abutment is thicker, more whitish (T: tough) than the gums away from the abutment (L, loose).  Return to main article
