Its similar to someone making a chicken sandwich but then giving you something that looks like chicken and tastes like chicken but it sure is not chicken. I always have all of my models, denture acrylics etc mixed to manufactures water and powder ratios this way I know it is done correctly and if it is not correct its a manufactures error as i am accurately following guidelines. (The dreaded words for Dentist & Technicians)Īs you can see from the example it shows one person is missing, where is the person who mixed the impression material which is the most important job, more important than taking the impression as they are creating the material for you to take the impression. Lab: Great impression, dentist has taken accurate impressions, models casts with all areas maintained, all denture stages followed, dentures finished, "great, off you go to get fitted".ĭentist: "F/F does not fit, please remake". You do not want to make life more difficult knowing that your great detailed impression taken is now great to look at but dimensionally unstable due to the properties within the material altered.ĭentist: Patient is a gagger, edentulous, impression taken with all anatomical landmarks, border moulding, all vestibule areas are very nicely detailed within the impression, "I am happy with the result and believe that I will get a really nice denture to fit". There is the taking the impression part which is an art form in it self with implications of everything else that goes with it. How many of you get a Dental Nurse to mix your alginate? How many of you rush to get the impression taken because it is setting in the tray? Sound familiar. If you do not mix materials with the recommended powder and water ratiosyou will alter the materials properties, simple as that. ![]()
