Q

In this X-ray We can see:
chronology of the eruption
eruptive trajectory
agenesis, supernumerary
TMJ(ATM) morphology
ramify morphology
different types of pathologies
fracture lines

A

Panoramic

18
Q

it is most used dx method to determine the level of bone maturation

A

Carpal x ray

19
Q

How can we get the level of bone maturation?

A

In the carpal x ray

used to evaluate the patient’s bone age and establish a relationship with their chronological age in order to determine the level of development and maturation

20
Q

the ossification of the sesamoid bone of the thumb - it coincides with the beginning of the

A

Pubertal outbreak

And is ideal for the beginning of ortho tx

21
Q

The ossification of which bone, and where is it, determines the beginning of the ortho tx

A

Sesamoid bone
In the thumb

22
Q

When do we indicate a carpal x ray

A

in px who show a severe discrepancy between dental age and chronological age
determination of the state of skeletal maturity before performing ortho tx
predict the onset of pubertal growth
px between 16 and 20 yo who need ortho surgery

23
Q

it allows the assessment of asymmetries of the skull, face and jaws as well as the frontal position of the dental organs

A

Postero-anterior

24
Q

The postero-anterior X-ray is indicated for:

A
  • dx for latero-deviations / laterognathia
  • severe midline deviation
  • dx of mal positions that affect different structures
  • studies the transverse anomalies
25
Q

it is a technology that provides high-resolution images of the craniofacial complex in three dimensions (3D). This vision goes with the movements made to correct malocclusion or facial asymmetries

A

CBCT
Cone beam

26
Q

CT has led ortho to change their dx imaging, including possible changes in ortho

A
27
Q

they are precise reproductions of the teeth and their surrounding soft tissues

A

Dental cast

28
Q

measurements of discrepancies are made between the dental arches and basal arches to obtain degrees of crowding,

A

…

29
Q

The duty models (dental casts) allow us to observe:

A

Anomalies in shape and size and number of dental organs.
Diastemas.
Insertion of the braces.
Midline discrepancy.
Anterior or posterior crossbite.
Openbite.
Curve of Spee.
Morphology of interdental papillae.
Shape and height of the palate.

30
Q

Helps in measuring arch length, and tooth size.
arch width
arch length
analysis of available space
overjet and overbite
molar and canine relationship

A

Dental cast

31
Q

They allow the study of occlusion from all aspects
See the progress of the tx
See the evaluation and study of the severity of malocclusion

A

Dental cast

32
Q

It allows the px to compare before and after the treatment

A

Dental cast
