AUTUMN MIDTERM: Mounting + zirconia Flashcards
what are articulator uses
- relate mandible and maxillary casts
- act as patient
- patient presentation
- tool to produce partial and full dentures
- fabrication of occlusal surfaces for indirect restorations
(decreases chair time when delivering restorations without tongue etc)
what is the intercondylar distance and condylar guide inclination of non adjustable articulators
whats the benefit?
intercondylar distance is set at 110 mm and condylar guide inclination of 20-30 degrees
-inexpensive and fast/easy mounting
what is characteristic of the arcon articulator
has “condyles” on lower part, and “fossae” on the upper part
where do you put vanilla bite
on the index tray of the kois dental analyzer
where do you line up the indicator rod on patient
vertical indicator rod to inter-pupillary line (facial midline) NOT the dental midline
how should the posterior portion of the analyzer bow be positioned
aligned with the horizon or level with the floor (patient sitting up, horizontal to floor)
where should the mounting platform be set to
+5
where does the index tray go
on the mounting platform
what are the notches made onthe casts and what are the dimensions
3 notches (indexing modeL) -2 in posterior area and one in anterior area. notches should be around 15 mm to 20 mm long. flare the wall of the notches to prevent undercuts
monolithic zirconia: what is the passing range for occlusal reduction
- 01 - 1.99 mm
1. 0 is a fail and 2 mm is a fail
monolithic zirconia: what is the passing range for axial reduction
ideal = 1 mm
.51 -1.49 mm (.5 is a fail and 1.5 is a fail)
monolithic zirconia: what is the taper passing range
1-9 degrees
monolithic zirconia: what is the margin depth range?
.51 mm- 1mm
.5 mm is a fail and 1.01 mm is a fail
monolithic zirconia : what is the margin location passng range
0-1.49 mm (1.5 mm is a fail)
