Adult interdisciplinary Orthodontic Treatment

Question 1

True or false… adults have an increased prevalence of root resorption during orthodontic treatment

Answer 1

True

Question 2

Name some perio procedures that should be done prior to commencement of orthodontic treatment

Answer 2

SRP

Open flap surgery

Gingival grafting

Bone grafting procedures to increase alveolar width and height in edentulous area, through wich tooth movement is to occur

Question 3

What perio procedure should be done after orthodontic treatment? Why?

Answer 3

Recontouring osseous surgery

The architecture of the bone changes with tooth movement

Question 4

True or false… equilibration of occlusal interferences that may arise during treatment should only be performed at the end of treatment.

Answer 4

False… it should be done at each appointment as necessary to avoid periodontal breakdown and excessive tooth mobility from occlusal trauma

Question 5

After orthodontic treatment has been completed and teeth have been retained, name the following in order:

Final occlusal adjustment
Continued periodontal care
Re-evaluation for further therapy 
Restorative prosthetic dentistry 
Completion of periodontal treatment

Answer 5

1) reevaluation
2) completion of periodontal treatment
3) final occlusal adjustment
4) restorative prosthetic dentistry
5) continued periodontal care

Question 6

Molar uprighting is best accomplished with limited treatment when an acceptable occlusion with anterior guidance and cuspid is is present and in patients with a normal vertical dimension. Patients with ___ faces are not good candidates for molar uprighting, which distalizes the molar which causes…

Answer 6

Dolichocephalic

Further increases the vertical dimension, with concomitant development of a dental openbite

Question 7

When uprighting a molar, standard brackets can be used on the anchoring teeth (___), and a ___ is placed on the molar(s) to be uprighted. This allows for the placement of a ___ when necessary.

Answer 7

Cuspids and bicuspids

Double buccal tube

Auxiliary uprighting spring

Question 8

True or false.. during molar uprighting, periodic occlusal adjustment and root planing of the tooth being uprighted is recommended to avoid trauma from occlusion, excessive tooth mobility, and pain as well as promote periodontal healing

Answer 8

True

Question 9

How long should you wait after molar uprighting to place the bridge or implant? Why?

Answer 9

8-12 weeks

It should be postponed until the reappearance of the lamina dura around the uprighted tooth

Question 10

What is an important restorative consideration with extruded teeth?

Answer 10

It will be extra-tapered from the occlusal to gingival margin due to the smaller dimension of the root surface

Question 11

Crowding and rotations of teeth are the result of ___

Answer 11

Tooth size/ arch length discrepancies

Question 12

Name 4 ways to alleviate tooth size/arch length discrepancies

Answer 12

Flaring of anterior teeth

Transverse expansion of dental arches

IPR

Extractions

Question 13

Approximately __ of enamel can be removed from the M and D surfaces of the upper anterior for a total of __-__mm. Because of the smaller diameter of lower teeth, however, less reduction is possible.

Answer 13

0.5

4-5mm

Question 14

What is advisable after orthodontically treating perio-compromised teeth?

Answer 14

Permanent splinting

Question 15

The replacement of missing teeth should be done ___-___ months after the removal of fixed orthodontic appliances. Delaying their replacement can cause the loss of tooth alignment and bite collapse

Answer 15

3-6 months

Question 16

The minimum amount of space needed for the placement of an implant to replace a maxillary lateral incisor is ___ at the root level. This allows for a minimum of __mm space mesial and distal to the implant

Answer 16

6

1

Question 17

In order to reduce the apperance of black triangles, in addition to IPR, what can be done with central incisors?

Answer 17

Reduce the distal tip of central incisors will approximate the crowns gingivally, decreasing the size of the space. When this is done, recontouring of the incisal edges may be necessary

Question 18

TADs have made what movements possible?

Answer 18

Single or multiple teeth intrusion

Space closure of edentulous spaces through a narrow alveolar ridge

Anterior en-mass retraction

Distalization into posterior edentulous spaces
