    Hi

    Had an impression for a denture last week and again another today. My
    dentist also the wax fitting and made adjustments to that.

    Only just dawned on me to ask why a second impression

    1st impression is used to make a model on which a custom fitted impression tray
    is made. This increases the accuracy and decreases the distortion. Also allows
    for border moulding.

    Purpose is to get a better fit.

    Another nice way is to border mold the old dentures and take a "wash"
    impression. Send it to the lab and have the lab pour models, duplicate the
    set-up with new teeth, and reline the old dentures prior to returning it.
    You get to do a wax try-in of new dentures which approximate what the
    patient is used to, and give the patient relined previous dentures which
    becomes better spare dentures. Adjust the wax-try as needed to compensate
    for tooth wear and improved esthetics/phonetics, and send back to the lab
    for processing.

    Is Plastogum, the material from Bosworth? If so please explain the technique.

    The Accudent is not really that expensive, when one considers the cost of final
    impression materials and custom trays.

    | yes but
    | using plastogum .You are making impression tray and functional impression in
    | "one shot" so Its more simpler.
    | using acudent You can make it also but this system is more expensive.
    |

    |
    | hah anyway if you have wax try-in or new denture you can make dublication in

    Sounds good if the original dentures are suitable for working with. Many are
    not. Most times that I recommend replacing dentures is because the originals
    violate the basic principles of prosthetic dentistry.

    If the original was suitable I'd suggest using tissue conditioner for a
    functional impression which would also prep for a better final.

    Many labs will do this service in one day. (Not the wax try-in). If you
    make the impressions in the dentures early in the morning, the lab will pick
    it up, make their models, reline the dentures and return the case that
    afternoon. A week later, the wax-try is ready to do. The patient only has
    to hide from the public for 5-7 hours.

    Some of the tissues are tightly bound to bone and some are loose and
    elastic. The first impression captures the tightly bound tissues and
    allows the fabrication of a custom tray. From the custom tray a second
    impression is made that captures the more movable tissues at the
    peripheries of the dentures and also a final wash of the tightly bound
    tissues. Some dentists do it all in one one impression but I prefer the
    two impression technique.

    Me too, except for the nightmare cases where there is floppy
    tissue on the ridges and the patient won't go to a surgeon to
    make things better.

    Custom trays and vinyl will squeeze and displace the tissue.
    The denture will do the same. Bad combo.

    So then what do you do on the flaccid ridge cases ?

    Quit using two impr technic for F/ many years ago.
    Using Jeltrate plus in an edentulous tray, but am the only
    guy that my prosth lab will accept an alginate from.

    Only time using a custom tray is when the arch is too large
    to be accomodated by a stock tray. This goes for partials too.

    Soft mix of alginate in an appropriate edentulous tray.

    I got a whole set of them on a public TV auction years
    ago for less than $100.
