I was quoted this last week.  I live in Virginia in a rural area.  The cost
of the implant was $2,000.  The cost of the crown was $1,000.  ($12,000 for
4 teeth)

    The costs for an implant retained crown are higher than for a natural
tooth because it is necessary to have what is called an abutment which
inserts (usually by screw) into the implant fixture.  If the fixture
(what is surgically placed) is in an ideal location it may be possible
to use a stock implant abutment (out of the box) which may be $150-$250.
 However, frequently the fixture is not placed in an ideal position,
and a custom implant must be fabricated by that lab in order to place
the crown with a more or less correct position and orientation.  This
may be as much as $500.
    The way I personally charge is to subtract the normal lab fee for a
regular crown from the total lab fee.  I then add this additional lab
fee onto my regular crown fee.  In other words, I simply charge the
patient the additional lab fee.
    This is not an ideal situation.  I like to be able to quote a patient a
fee in advance.  However, I don't want to jack up my fee to cover all
contingencies if it winds up being less expensive.  So far my patients
have been able to understand this if I give them a range of fees.
