1.	To achieve precise marginal fit in the Wol-Ceram system:
	a.		electrically conductive wax is placed on the master die
	b.		no die spacer is used
	c.		no electrically conductive wax is used on occlusal surfaces of posteriors, or incisolingual surfaces of anteriors
	d.		all of the above
2.	The positive vertical stop aspect of the Wol-Ceram system provides:
	a.		maximum strength
	b.		takes pressure off the crown margin, allowing any margin design
	c.		provides a vertical stop when seating the restoration
	d.		all of the above
3.	The composition of the Wol-Ceram coping is:
	a.		aluminous oxide based on Vita® Inceram
	b.		zirconium oxide
	c.		zinc oxide
	d.		titanium oxide
4.	After dipping, the Wol-Ceram coping has a uniform thickness of:
	a.		0.15 mm
	b.		0.6 mm
	c.		6.0 mm
	d.		depends on the number of dips
5.	The sintering cycle for Wol-Ceram is:
	a.		2 minutes
	b.		2 hours
	c.		2 days
	d.		1 hour per unit
6.	The infiltration glass:
	a.		eliminates the need for opaque
	b.		increases strength by reinforcing the coping
	c.		increases the esthetics of the coping through the use of Vita shades
	d.		all of the above
7.	The Vita® 3-D Master shade guide:
	a.		is superior to the Vita® Classic shade guide
	b.		allows you to measure value, hue and chroma separately
	c.		has true interpolated shades
	d.		all of the above
8.	A soft tissue model is useful:
	a.		on all anterior cases
	b.		as a virtual try-in prior to temporary removal
	c.		to ensure gingival embrasures will be closed
	d.		all of the above
9.	The tissue trimmer from Axis Dental should be used:
	a.		in a slow speed handpiece with water
	b.		in a slow speed handpiece without water
	c.		in a high speed handpiece with water
	d.		in a high speed handpiece without water
10.	The preparation technique shown in this presentation is called the reverse preparation technique because:
	a.		the bur is used in reverse to cut the tooth
	b.		the impression is taken before the preparation
	c.		the gingival reduction is accomplished first, rather than last
	d.		build-ups are placed prior to gross reduction of the tooth
