Q

Supervision of exfoliation OR premature extraction of primary teeth and eruption of permanent teeth

To ensure that treatment can be provided before malocclusion is established (since permanent anterior teeth are generally larger than primary, and malocclusion becomes more evident as eruption progresses)

Q

Refers to the surgical movement of bone

A

Orthognathic

18
Q

Refers to the elimination or modification of abnormal perioral muscle function

A

Myofunctional

19
Q

Refers to treatment which addresses patient psyche (motivation to cooperate with oral hygiene practices/control of certain habits

A

Psychological

20
Q

Involves observation and adjustment of an appliance which is producing orthodontic/orthopaedic force

A

Active Treatment

21
Q

Involves observation of a patient and possible management of an appliance which maintains the status quo rather than exerting force

A

Passive Treatment

22
Q

Orthodontic Force produces movement in 2 phases

A

1 the tooth moves due to the elasticity of the periodontal ligament and deflection of non rigid alveolar bone just below the crown of the tooth

2 the tooth moves in conjunction with remodeling of the alveolar bone

23
Q

5 mechanics/steps of alveolar bone remodeling in response to orthodontic force

A

1a force pushes the tooth toward one side of the alveolar (compressing the periodontal ligament on that side)
2the tooth is pulled away from the opposite side of the alveolus (stretching the periodontal ligament on that side
3side where tooth moves, compression stimulates osteoclasts to resorb bone and make space for tooth to move
4side where tooth is moving from tension stimulates osteoblasts to produce bone to fill in the gap
5ultimately, the alveolus bone maintains its original size, but the entire alveolus has been displaced the allow relocation of the tooth

24
Q

Orthodontic forces do not produce tooth movement in isolation

True or False

A

True. Some of the periodontal ligament fibers run mesiodistally from tooth to tooth, linking the teeth together

Even teeth which are not connected by periodontal ligaments will be affected if they are in contact with the same appliance due to reciprocal force [force of corresponding magnitude but opposite direction like an elastic band stretched between your fingers]

25
Q

Orthopaedic forces are stronger than orthodontic forces

True or False

Influence _____ ______ and/or _____ ______ rather than just alveolar bone

A

True

Facial sutures and/or mandibular condyles

26
Q

The left and right halves of the maxilla meet at a ______

A joint consisting of dense fibers and small bony interdigitations

A

Suture

27
Q

As a patient gets older the fibers at the maxillary suture are replaced with ______

A

Bone

28
Q

Until mid-to-late teens palatial expansion force for the correction of a posterior cross bite will

  1. tear ____
  2. fracture ____
  3. separate _____
A
  1. Tear (internally) the fibers between the two halves of the maxilla
  2. Fracture the small bony interdigitations of the suture
  3. Separate the bones of the two halves of the maxilla through disruption of the mid-palatal suture and pressure against other maxillary sutures
29
Q

In class 2 patients with a protrusive maxilla _________ or______ headgear may be used to retreat the maxilla, maxillary Teeth, or restrain maxillary forward growth

A

Occipital (high-pull) or Cervical (low-pull)

30
Q

In class 3 patients with a restrusive maxillary ______ (also known as reverse-pull headgear or facemask) attempts orthopaedic maxillary _____

A

Protraction head gear

Protraction

31
Q

Physiologically maxillary retraction or protraction affects growth at the _____ through _____ directed force

A

At the sutures

Anteroposteriorly

32
Q

In open bite patients orthopaedic force can be directed toward the ——— or the mandible

Occipital head gear force against maxillary molars may ____ the _____ maxillary teeth to assist with bite closure

Chin cup force against the anterior part of the _______ restrains _____ growth of the ______ by restricting _______ growth of the teeth
HEADGEAR

A

Maxilla

Intrude the posterior maxillary

Mandible restrains vertical growth of the mandible by restricting vertical growth of the teeth
