(405) Although a mouthguard does not prevent the teeth from fracturing, it does

prevent teeth fragments from damaging the oral tissue

(405) One purpose of a mouthguard is to reduce the risk of concussion by

acting as a shock absorber.

(405) The buccal flange of a mouthguard normally extends to the

point where soft tissue meets the attached gingival.

(405) Before placing a dental cast in a vacuum adaption machine, you soak the cast in water for a couple of seconds to

prevent the hot thermoplastic material from adhering to the cast

(405) What polishing, if any, is done to the periphery of a mouthguard?

A light flame with alcohol torch is used

(405) What purpose does a stint serve

Make provisional restorations

(405) In fabricating a stint for a fixed partial denture (FPD) provisional restoration, what action, if any, is taken to fill the edentulous space?

Adapt resin denture teeth.

(405) In prosthodontics, how will you know when the material for a stint is overheated?

Small bubbles appear

(405) In fabricating a prosthodontic stint, what is used to cut away excess material in the sulcus areas and form around the base of the cast?

Heated Bard-Parker knife.

(405) In prosthodontics, the unused arch sections of a provisional stint should be

kept.

(405) The thinning and stretching of a mouthguard is caused by

overheating the material

(406) What dental specialty studies and supervises the growth and development of dentition and corrects growth and development abnormalities in children and adults?

Orhtodontics

(406) What two factors cause people to seek orthodontic treatment?

Appearance and impaired dental function

(406) The three types of orthodontic treatment are

preventive, interceptive, and corrective.

(406) What orthodontic appliance is used to prevent teeth from tipping or drifting into a vacant space?

Space maintainer.

(406) Orthodontic treatment aimed at correcting developing problems to prevent them from becoming worse is called

interceptive

(406) What complex orthodontic treatment involves the use of mechanical appliances to restore the dentition to fully functional and esthetic condition?

Corrective.

(407) Facial attachments on orthodontic bands are

brackets

(407) Which dental instrument has a ball-and-socket opposing ends used for better band adaptation around the tooth?

Band contouring pliers.

(407) Which type of ligature pliers has a round, metal cylinder with a channel and forked, blunt opposing tips for passage of the ligature wire?

Coon.

(407) Which orthodontic instrument has a safety hold feature to prevent loose wire from impacting and embedding into the intraoral tissue?

Distal end cutter.

(407) Which orthodontic instrument is used with heavy wire up to 1.6 mm diameter and is easily identified because each beak has a rounded notch at a right angle to the beak near the tip?

Face-bow adjusting pliers.

(407) Which type of orthodontic pliers is used for bending small wire, spring forming, and contouring brackets?

Bird-beak

(407) Which type of orthodontic pliers has the outer one-third of the concave beak serrated to avoid wire slippage and a round beak generally with three sections of various diameters?

Tweed loop-forming.

(407) Which type of orthodontic utility pliers is used to hold or grasp the arch wire to make adjustment bends, or place the arch wire in, and remove it from the mouth?

Weingart

(408) What type of radiograph does the dentist trace and analyze by linear and angular measurements, compare and assess the growth pattern of the patient, and the effect of orthodontic treatment has on skeletal development?

Cephalometric.

(408) All of the following are intraoral photographs documenting the patient’s dental esthetics and condition of the oral hard and soft tissues except

right and left lateral views with the teeth open

(408) All of the following are part of the standard extraoral series taken at the beginning of orthodontic treatment except

Straight profile from the left lateral view and full-face frontal view

(408) Following examination, diagnosis, and treatment presentation, fixed orthodontic treatment usually begins with the

placement of orthodontic separators.

(408) Which basic step is not required for orthodontic bonding?

Trial sizing and rebonding of loose brackets.

(408) Placement of orthodontic bands requires all of the following steps except

acid etch and bonding

(408) When is the orthodontic patient usually scheduled for adjustments, after placement and ligation of the arch wires?

3 to 4 weeks

(408) How should you check for loose bands at each orthodontic adjustment appointment?

Place the end of a scaler on the gingival edge of the band and tug lightly in the occlusal direction.

(408) Following removal of fixed orthodontic appliances, how long does the dentist usually recommend the wear of a retainer?

A full time basis for 6 months to a year.
