Prosto lab 1

The aim of this lab was to differeniate between the dr and tech

work because you are going towork as both now and in 4th

 year

major equipments u will need are the rubber bowel and the

spatula prefered to be plastic not metal and some burs we are

going to talk aboutthem later on

*** First the dentist when any patient needing complete pr

partial dnture he must do things step by step inorder to reach

the best result and the complete that he will be proud of it and

these steps are :

1 examination of patient intra and extra orally

2 selecting the most suitable tray that he will need it to work

with it

3 taking primary impression

4 taking secondary impression depending on the secondary

tray for more details

5 chek the GRR which is the jaw realtion ridge as I call

resembling also the realtion between of occlusion through

thewax rim that is done and select the shade of teeth that is

suitable for the patient

6 try in the denture tomake sure it is perfect and there is

nothing that is unsuitable or making troublesfor the patient

7 delivery of the denture to patient

future you will not be responsilbe for it there will be someone

doing it for you but you must have a background about it and

you will spend this year working as tech and as a dentists andthe steps that the tech must work by them are :

1 make a cast from the primary impression he got from the dr

to make secondary tray that is more aqqurate in recording

details

2 making base plate from secondary impression and forming

wax rim aslo

3 after the dr set the Grr tech will set the teeth and put plaster

which will use to remove the wax and then put acrylic insed it

to make the denture
