Please note the following in the case of remoulding Boil&Bite MADs: Prior to remoulding, the old dental impressions in the MAD must be smoothed out, so that you bite into a smoothed surface during the remoulding. The moulding should not be based on old dental impressions (as this comes with the risk of the MAD fitting too loosely). As far as the procedure is concerned, you should warm up the MAD as you would for an initial fitting, followed by smoothing out the old dental impressions, let it cool down and, finally, reheat the MAD. If you attempt to complete the “smoothing” and moulding in one go, there is the risk of the MAD rehardening too soon and the dental impression, therefore, not being deep enough . Consequently, the MAD may fit too loosely).
