032 GC plier —> ____ beak plier for bending lighter wires as ____ for wires being
placed for the pt
034 XC —> ____ beak plier for nance appliance (____) and fixed lingual retainer (____); more lab-based plier for heavier more rigid appliances like nance and hawley

For helices wanna them to have ____, good ____, and proper ____ and ensure that each helix is lying flat on the page as you go
symmetry
spacing
sequence
One thing to note on the ____ plier you have notches which is a helpful guide to affect the diameter of helices ..you wanna be consistent and choose the same notch every time for consistent size

Lab session II: banding and bonding exercise on typodonts and models maxillary stone model to bend ____ wire for nance appliance
0.30
Fixed
- brackets, bands, ____, ____
Removable
- ____, ____
As part of fixed appliance therapy to disarticulate poster teeth we are gonna use the ____ to get more efficient uprighting especially of mandibular teeth
…* He is always asked if we can use invasigln or other corrective aligners for some of these procedures ? you absolutely can but the initial data collection and model making aspects is to be done regardless of course of tx
* ____ is important to know if a specific pt is good candidate for invisalign/corrective align therapy
nance
3x3
hawley
corrective aligners
hawley bite plate
case selection
when we place brackets and bands on our teeth …we are gonna place brackets on the ____ of the tooth..make sure the center of bracket aligns w/ long axis of tooth…we will place arch wire in Lab 3….we are gonna go over ligation each bracket
middle 1/3rd
Brackets have series of components : we will talk about them in my other lectures w/ you we have:
• ____
• ____
• ____
bracket base
tie wings
arch wire slot
• When we actually place brackets on the teeth this afternoon, one thing to note is the little dot on the bracket should be positioned ____
and ____ to ensure that the bracket is placed correctly not upside down —> otherwise will reverse some of the prescription aspects of bracket itself
distally
gingivally
- We’re going to place the brackets almost in a straight line without considering ideal bracket position so we can place a passive wire through the main slot (in red)
- For the bracket placed on the tilted molar, we would want to place it in ideal position and is aligned to the ____ of the tooth (in blue) because the force generated will upright and distalize the molar.
- The anterior brackets are used as an ____ for the molar uprighting.
long axis
anchorage
• Nance appliance has a couple different uses but the most common is a ____. Usually maintains the space when primary molars are lost early until we see the emergence of the primary tooth.
◦ For example, emergence of ____ if we lost the primary second molar prematurely.
space maintainer
second premolar
• Another use would be in combination in fixed appliance therapy to maximize ____.
• the the picture you can see the nance appliance on the molar and that is to keep the molars in that position
while pulling the anterior teeth back with the fixed appliance
anchorage
- the appliance is typically fabricated by putting ____ between posterior teeth. We would fit band on this particular patient that is going to require the device itself. We’re going to take an ____ to pick up the bands iself and pour them in a working model. Then the lab would fabricate the nance by bending the wrought wire and soldering.
- The button is going to be invested in ____ and will use the rugae to keep pressure on the posterior teeth from drifting mesially.
- In lab we will just be bending the wrought wire
- The conventional way of doing this is to manually fit bands on an ____
spacers/separators
alginate impression
acrylic
uptake impression

Clinical Applications of Nance Appliance
n Prevent mesial drift of the ____
n Maintain ____ in Early Treatment cases
n Anchorage for ____ retraction
n Anchorage to distalize ____
• if we set the nance on the 1st molars, we can get distalization on the 2nd molars
n Anchorage for ____ retraction
n Auxiliaries (____
maxillary molars leeway space maxillary anterior maxillary molars mandibular anterior tongue crib
