Q

What can be done virtually to plan the aligner to move the teeth closer and close space?

A

Virtual C-chain

17
Q

Why would bringing the roots together be a concern in ortho?

A

Can use that to close a dark triangle

18
Q

What else can be used as an adjunct to close a dark triangle?

A

Interproximal reduction

19
Q

What is the hygiene for the aligner?

A
  1. Ultrasonic cleaner
  2. Place in water when eating
  3. Clean with a toothbrush before adding toothpaste
20
Q

What is a concern when trying to correct crowding by proclining the teeth?

A

Patient must have adequate attached keratinized attached gingiva

21
Q

What are some ways to correct crowding?

A
  1. Interproximal reduction
  2. Expansion (not lower canines)
  3. Proclination (watching the attached gingival)
  4. 4xEXT, braces 1st premolar to molars, close the space, anterior teeth will move into the space
  5. Air Rotor stripping
22
Q

What is a concern when doing Air Rotor Stripping to make room to correct crowding?

A

After remove spacers ensure you do not create a ledge or a food trap

23
Q

When doing expansion (Transverse corrections) how much more should you expand?

A

1/3 more than you need

24
Q

What are methods for doing sagittal movements?

A

Rubber bands attached to the aligners or TADS for a single arch

25
Q

When should sagittal movements be done in invisalign treatment?

A

Close to the beginning of treatment

26
Q

What is a good thing about the early posterior contact with invisalign with respect to closing an anterior open bite?

A

The early posterior contact will intrude the molars and naturally close the anterior open bite

27
Q

What can be done if the patient has a forward tongue position contributing to an open bite (Vertical correction)?

A

Use a cross arch rubber band to remind tongue to stay back

28
Q

What would you like to extrude to open a deep bite?

A

The premolars

29
Q

What can be done to the aligners to help posterior teeth erupt a bit to open a deep bite?

A

Put turbos or elastics on the linguals of the anterior aligners that opens up space for posteriors to erupt into

30
Q

What can be used if there are tracking problems?

A

Have the patient chew whenever you put the aligner in.

31
Q

What are 2 movements that require attachments?

Q

How are attachments placed?

A

In the direction you want to move the tooth

Q

Should attachments be placed in the first visit (i.e. with the first set of aligners?

A

No. Give them 2 trays (1 month) then place attachments at one month visit

34
Q

Is there any urgency to replace an attachment if it falls off?

A

No, unless you are rotating teeth

35
Q

What is used to do rotations in invisalign?

A

Place buttons on buccal and lingual, then use a band to rotate

36
Q

What is common in the rotation of canines pretreatment?

A

Canines usually rotated in the same direction

37
Q

What is caused by wearing aligners well, and how can it be corrected?

A

The dentist, NOT the lab tech

39
Q
