When seating enamel bonded restorations, if the etched enamel becomes contaminated
with saliva, how should it be treated - Answers - Re-etch enamel for 15 seconds, rinse,
dry, then apply bonding agent.
When teeth overerupt, they bring the bone and gingiva with them. This is termed

The average incisal display of the maxillary central incisors of 20-year-old females in
repose is__________ mm. - Answers - 3-4
The average upper lip length for a young female is __ mm - Answers - 20-22
(T/F) When a dental implant is placed at the same time as an extraction (immediate
implant), the bone remodeling process does not take place in which the bone resorbs
from the facial to the lingual, often resulting in compromised bone dimensions. If no
immediate implant or bone grafting is completed at the time of extraction, resorption has
been shown to result in approximately 1 to 2 mm of vertical bone height and 4 to 5 mm
of horizontal bone width within 1 to 3 years. - Answers - Both T

To minimize operative trauma to the implant surgical site in D3 bone, the final phase of
site preparation should be prepared with a/an - Answers - ultra slow-handpiece, high
torque (15-30 rpm)
, With immediate implant placement, the implant-bone interface is weakest and at most
risk of overload at 3 to 6 weeks after surgical insertion. At 4 months the bone is still only
_____ % mineralized, organized lamellar bone. - Answers - 60
(T/F) An important complication to prevent after implant surgery is infection. To reduce
infection the clinician should prescribe an appropriate antibiotic, a .12% chlorhexidine

Answers - Both T
(T/F) When comparing nonresorbable vs resorbable guided bone regeneration (GBR)
membranes, a disadvantage of nonresorbable membranes includes the need for reentry
procedures for membrane removal and frequent postoperative infections that may follow
premature membrane exposure. In order to overcome these limitations, resorbable
membranes have become a popular alternative because they are biodegradable and
are less likely to become infected even in the event of exposure. - Answers - Both T
