How does 3M True Definition claim to lower lab and labor costs?
Faster seating time and fewer remakes due to PRECISE fitting restorations (99.7% fit rate)
The 3M True Definition Scanner is cheap. So why is digital imaging still considered expensive?
every time an image is uploaded to the server and sent to the “connection center” there is a charge to your office

Very Accurate
TRIOS by 3Shape allows you to choose between which two options?
cart solution
pod solution
Which intraoral scanner is completely portable and is from Carestream Dental (an offspring of KODAK)?

d. +/- 25 microns
+/- 25 microns
Digital Imaging with CAD/CAM all in one system includes which three systems? What is the benefit of this?
- Carestream
- Planmecca (E4D)
- Sirona Cerec
One company = takes responsibility for errors
What does CAD/CAM stand for?
Computer Aided Design/ Computer Aided Machining
What is the difference between “copy milling” and “CAD/CAM milling?”
Copy Milling = mechanical scanner (uses replica as guide)
CAD/CAM milling = optical scanner (uses digital information)
CAD/CAM was introduced into industrial settings in the _____ and the first CEREC 2D design software was introduced in the ______ (when sharples graduated).
1950s
1980s (83-85)
When was the CEREC 3D design software introduced? (when sharples started at OSU)
2003
True or False: PlanScan Intraoral Scanner from Planmeca (USA) is probably where OSU technology will be investing in the future.
True
Planmeca PlanScan technology is ______, ________, ______ and ______.
easy (no powder)
accurate (short wavelengths)
fast
convenient (self-replacing burs)
Why is Planmeca PlanScan so accurate?
it uses a smaller wavelength (450nm) which is more reflective and results in sharper images
True or False: E4D, Cerec, and True Definition can be used for fabricating FPDs.
True
What are the three CEREC Block options?
- Glass Ceramic
- Lithium Disilicate
- Composite Resin
Zirconia material is less _____ but higher ______.
esthetic
strength
(use in the posterior)
Vita Alumina, Vita Spinell, Vita Zirconium, and eMAX ZirCAD are examples of ______.
high strength lab coping ceramics
True or False: Crystallize –> Mill –> Glaze
False: Mill, Crystallize, Glaze
True or False: Zirconia is not typically a one-day chairside crown.
True, it has a 4-6 hours crystallization process
True or False: IPS EmpressCAD is the most esthetic chairside material.
True, Empress = perfect like a princess
What are the three chairside block materials used for provisionals?
- VITA CAD-Temp
- artBloc Temp
- artegral ImCrown (used with Cerec 3D)
What are the two composite block materials made by 3M?
- Paradigm MZ100
2. Lava Ultimate
How can Paradigm blocks be modified?
internal shades can be modified with Sinfony to make more or less translucent
Mark II, Sirona, Empress, e-max, and paradigm C are examples of ______ blocks.
ceramic
Which block material is sometimes called the “blue block?”
e-max (Lithium Disilicate)
Ceramic materials are etched with ________ acid in order to bond.
hydrofluoric acid
True or False: Empress blocks take translucency into consideration.
True,
HT = high
LT = low
What is the second strongest ceramic material, behind zirconia?
Lithium Disilicate (IPS e.MAX)
Why is it important that you indicate the material choice prior to milling a restoration?
the restoration WILL shrink, the system will take this into consideration based on the material of choice
How long is the Crystallization and Glazing cycle? What is required during this process?
19 mins (plus warm-up/cool-down ~25 total) vacuum is required
Place the machinable materials in order of flexural strength (strong to weak).
