3B. Band and Bond

Question 1

• •
we will also use the tip of the explorer or scaler to remove excess around the margin of the bracket certain materials like this transcend plus has this ____ hue to it
◦ it’s a color ____ material, so when we place the bracket on the tooth, we will see this composite material exude around the surface of the tooth, so we’ll have the ability to see the material well and remove the access around the perimeter of the bracket
◦ and then we will light cure

Answer 1

pinkish

changing

Question 2

• what’s the importance of removing excess?
◦ ____ trap
◦ if this material rolls around the margin of the base, even with the best of brushing and flossing, the pt will have an area without good access
◦ when you debond the pt, you will have an incidence of ____ around the perimeter of bracket
◦ the material could discolor, so you can wind up seeing it become more unsightly for patients, where you
notice a glob of composite around the surface
◦ if it’s placed on excessively and rolls underneath the base, it could clog the ____ where you don’t have
the ability to get the ligature around all four of the tie wings

Answer 2

plaque
decalcifications
tie wings

Question 3

• in indirect bonding we are going to utilize a patient’s models
• either we take impressions and make ____ models or we’re going to do a ____ scan and print 3D models
• and just like when we had placed brackets on our Typodonts, we’re going to place our guide to know the
orientation of where we want the bracket with regard to the long axis of the tooth, the center slot of the bracket
• we’re going to place the brackets on the ____ or plaster models
◦ ideally with similar composite resin that we would bond to
• then we would exude PBS material (medium body)
◦ then we transfer the brackets off the model and it’s going to be held well into the ____ material
◦ then our technique will be the same as it was for direct bonding
‣ we’ll clean the surface of the tooth, etch, seal or use self etch primer, then place a tiny bit of composite material on the brackets
‣ we’ll transfer the PBS tray onto the ____, light cure and then we remove the PBS tray and we have brackets on the teeth!
‣ still have to place the arch wires

Answer 3

study
3D
resin

PBS
dentition

Question 4

• whats the advantage of indirect bonding?
◦ it’s less ____ consuming
◦ to place a full set of brackets with direct bonding it might take an hour plus chair time
◦ whereas if you consider indirect technique, it would take a lot less chair time, maybe 15 minutes of chair
time
◦ you can do many more full bondings on an individual day vs. having a lot of time where you have to take at
least an hour out of your schedule to do a full max and mand bonding
◦ NOT less accurate, actually ____ accurate than direct

• disadvantage?
◦ ____, more materials, more time, somebody has to place these brackets
◦ even though saving chair time, somebody has to sit in lab to place these brackets and do
this technique
• have to weigh advantage of saving chair time and the extra expense
• if other things happen where maybe you have a younger pt w partially erupted teeth then there’s
a delay where we will place trays but trays don’t fit well b/c now have more eruption, will have
incomplete seating of material
• something to know about b/c it’s something you’ll see
• something we’ve talked about in terms of current innovations, this is one of those

Answer 4

time
more
cost

LIGATION
____
____
____

Answer 5

Question 7

• the only difference in placing the lingual retainer is that the composite material is usually more ____ than we would use for bracket bonding
• the composite we use for restorative has a much greater viscosity versus a middle ground of our materials that we use for ____ placement versus a more ____ material for bonding lingual wires

Answer 7

flowable
bracket
flowable

Question 8

• for example if we have an exposed palatally impacted canine, it’s not just enough to expose
◦ we need to create a purchase on that tooth to guide that tooth in place
◦ if we placed a regular bracket on the lingual aspect of the tooth, don’t have a good grip on tooth to bring into better position
◦ in a situation like this we are going to use an ____ or a button and an elastic thread to tie to the main arch wire to ____ that tooth to its better labial position
◦ once we get tooth to better position, then at that point we can place a labial attachment (conventional
bracket) to gain our 3D control of that tooth that was too palatal
• utilizing auxiliaries are important to utilize techniques like canine exposures

Answer 8

islet

retrieve
