Can an implant be used as an anchor (abutment) for a bridge?

    Last year I had teeth 18 & 22 (17 was extracted years ago) prepped to be
    used as anchors for a 4-tooth porcelain fixed bridge. The bridge was later
    attached to span teeth 18-22.

    Unfortunately the bridge came loose and a trip to my dentist revealed that
    tooth 22 was fractured and I was told he would have to basically start all
    over and replace the bridge with an appliance. Not an attractive option and
    not well received I might add.

    Anyway it recently occurred to me that perhaps the fractured tooth #22 could
    be replaced with an implant - thus allowing me to have the original bridge

    So my question is simply "Is this doable?" If so, what are the pitfalls, if
    any? Presumably I must see an oral surgeon for this.

    As always, thank you for your time.

    Obviously if I am saying a 4-tooth bridge, I should have stated that it
    spanned 18-21 - NOT 18-22. Sorry about that.

    Breaking a tooth like this probably points to night-time clenching (what I
    like to refer to as isometric-grinding). Clench with great force and rock
    the jaw back and forth with the teeth clamped down really hard. Eventually
    the weakest point will let go. The forces we are talking about here are
    enormous and you can do this while sleeping for many hours every night.
    Usually, the patient does not even know they are doing this until the
    dentist points out all the other effects which are evident.

    I have seen bridges supported by an implant on one end and a tooth on the
    other end hold up well long term. However, literature tells us this is not
    the wisest way to restore function. There is too much difference in
    compressibility of what is supporting the bridge on each end.

    You would probably be better served with two implants supporting a new
    3-unit bridge and cutting the crown off the back end of the old bridge and
    leaving it on the back tooth so that you do not have make a new crown there.

    Regardless of what plan of action you pursue, you need to protect your teeth
    while sleeping.

    Why not a post, depending on where it is fractured? Then one could

    Nope, an implant crown is different from a regular crown, plus a
    bridge cannot span a natural tooth and an implant anchor.

  5. I agree with the other dentists who recommend cutting the bridge
    leaving a crown for #18 and have two implants with a bridge. A bridge
    between a natural tooth and an implant is a bad idea.

    True, its like mixing Haagen Das ice cream with Shop-Rite chocolate
    sauce in the same bowl.

    You cannot attach an implant to a natural tooth.
    Natural teeth move. Implants do not.
    This dooms the bridge to failure.

    I would also advise you to get a predetermination for your insurance (if
    any) to see if the dentist that evaluated claims like this agrees with
    me or not. If the evaluating dentist doesn't believe it will work, your
    company won't insure it.

    I aslo agree with the others in saying you need to protect the rest of
    your mouth with an NTI. This goes DOUBLY so if you decide to get an all
    implant bridge and single crown.

    I want to thank all of you for taking the time to offer advice.

    It appears my two options are the following:

    1) Ask my regular dentist to go forward with his approach - which is to
    replace the 4-tooth fixed bridge with an appliance.


    2) Have an oral surgeon consider reattaching the bridge using two (as
    opposed to one) implants.

    Oh well.
