Same day denture work tips
I performed a same day tooth addition the other day and thought of a few tips:
-Take the shade and mould before anything else. Unfortunately I went ahead and took a pick up impression before this and after I had seated the tray I realised it wouldn't be possible t to chose which teeth would be placed as the denture was in the impression. Of course this can be left up to the technician but the more control you have over the procedure the better.
-If the denture is not stable, you should reline the denture at the same time. Take a reline impression and then a pickup. If no reline is needed, a pickup impression is sufficient. Before taking the pickup impression check the bite of the reline impression to ensure the denture has seated fully
-I thought it would be a good idea to use polident to stabilise the denture while taking the pickup impression. It must be noted that adhesive doesn't increase stability but improves retention. For stability, the denture must adapt well to the tissues and the ridge height and shape must be favourable. The only situation I can think of where stability is good but retention is bad is where there are no clasps. In this case for a pickup impression to add clasps, polident may come in handy.
-Don't assume that the impression hasn't moved the denture. There is no way to check if this has occured except perhaps sighting the poured up model but all you can do is take steps to ensure that it is fixed in place before the impression.
-Also relevant for new partial denture inserts, the place you have to most commonly adjust before insert is where acrylic contacts the teeth where it isn't blocked out correctly and acryllic flows under the undercuts. This is easy to spot on a chrome as the acrylic will have flowed over the guide planes. On an acrylic denture you will need to trial and error grind the denture till it fits in.
-To try and locate the tooth a denture is binding on, lightly place the denture in place until it binds then rock the denture all directions and/or jiggle each saddle area and see if it the one that is binding.
