"blank" is the most common contributor to malocclusion, condition that occurs when teeth are not properly aligned within the arch.
"blank" is excessive protrusion of the maxillary incisors.
"blank" is alack of vertical overlap of the maxillary incisors, creating an opening of the anterior teeth.
What two positions does the orthodontist evaluate for facial symmetry?
Frontal analysis- bilateral symmetry, size proportion of midline to lateral structures, vertical proportionally
profile analysis- to determine whether the jaws are proportionately positioned, evaluate lip protrusion and vertical facial proportions and mandibular plane angle

In what two ways can you measure an arch wire without placing it in the patients mouth?
Using study model
used arch wire that is being replaced
Besides the use of ligature ties, what technique can be used to hold an arch wire in place?
"blank" is another term for fixed orthodontic appliances
Braces= bands, brackets, arch wires, auxiliaries that can move a tooth in six directions- mesially, distally, lingually, facially, apically, occlusally
What is the sequence for appointments for the orthodontic patient?
1. placement of separators
2. cementation of molar bands
3. bonding of brackets
4. insertion or arch wire and trying in with ligature tie or elastomeric ties
