    What is difference between crown and onlay?

  2. A crown: The old filling is removed, decay is cleaned out, a filling is put
    back in, and then,,,, the tooth is ground down 360 degrees. All four sides
    are reduced in thickness and the biting surface is shortened. The crown
    then fits over this prepared area like a bottle cap, re-establishing full
    contours.

    An onlay: The old filling is removed, decay is cleaned out, an piece of
    porcelain is then fabricated which fits the space like a puzzle piece and is
    bonded in place filling the hole. Any and all solid tooth structure remains
    in place.

    Studies show expected failures during the first fifteen years to be very
    close for both procedures.

    Inherently, most dentists would vastly prefer an onlay in their own mouth,
    but do exclusively full crowns on their patients.

    In the case where 3/4 crown is lost, would onlay still be possible?
    Doing crown will have to cut all natural crown off and then build up.
    Is it better to do onlay to save more tooth?

    first molar had a big cavity and had root canal and old silver

    Mostly shape of the preparation and the ammount

    greater with an onlay. The downside to onlays is
    the increased linear measurement of the margins.

  6. Just do a new 3/4 crown. Almost the same as an onlay (depending on which
    school you trained at).

  7. Plus, virtually all of the margins are where you can reach them with a
    toothbrush on an onlay.

    Little bit prejudiced?

    I have three crowns and zero onlays in my own mouth (all are about
    8-10 years old, but I do wear an NTI...the last 6-7 years).

  9. When I ask dentists which they would prefer on their own teeth, most respond
    with onlay/inlay. Personal anedotal experience.

    (incidentally, I agree that most people for whom onlays/inlays are an
    option prefer them over crowns - but that's beside the point).
