8th Class

Question 1

______ is a process, which involves the collection of
an adequate data base of information about the
patient and the distillation from that data base, of a
comprehensive but clearly stated precise list of the
patient’s problems.

Answer 1

Diagnosis

Question 2

________ is an important tool in diagnosis and treatment planning.
•An ideal one of orthodontic conditions would summarize the
diagnostic data and imply the treatment plan.
•can be viewed as the (orderly) reduction of the database to a list
of the patient’s problems.

Answer 2

Classification

Question 3

•Step 1 is carried out during the initial clinical examination, while
facial asymmetry, anteroposterior and vertical facial proportions,
and lip–tooth relationships (at rest and on smile) are evaluated.
•The clinical findings can be checked against the facial photographs
and lateral cephalometric radiograph, which should confirm the
clinical judgment.

Answer 3

Evaluation of Facial Proportions & Esthetics

Question 4

•Step 2 is carried out by examining the dental arches from the
occlusal view, evaluating first the symmetry within each dental arch
and second the amount of crowding or spacing present.
•Space analysis quantifies crowding or spacing, but these figures
must be interpreted in the light of other findings in the total
evaluation of the patient.

Answer 4

Step 2:
Evaluation of Alignment and Symmetry
Within the Dental Arches

Question 5

• At this stage, the casts are brought into occlusion and the occlusal relationships are examined, beginning with the transverse (posterior crossbite) plane of space.
• The objectives are to accurately describe the occlusion and to distinguish between skeletal and dental contributions to malocclusion.

Answer 5

Step 3:

Evaluation of the Transverse Plane of Space

Question 6

•Examining the dental casts in occlusion will reveal any
anteroposterior problems in the buccal occlusion or in the anterior
relationships.
•It is important to ask whether an end-to-end, Class II or Class III
buccal segment relationship, or excessive overjet or reverse overjet
of the incisors, is caused by a jaw (skeletal) discrepancy, displaced
teeth on well-proportioned jaws (dental Class II or III), or a
combination of skeletal and dental displacement.

Answer 6

Step 4:

Evaluation of the Anteroposterior

Question 7

•The distinction between dental and skeletal is important because
the treatment for a skeletal Class II relationship in a child or adult
will be different from treatment for a dental Class II problem.
•Cephalometric analysis is needed to be precise about the nature of
the problem.
•The object is to accurately evaluate the underlying anatomic basis of
the malocclusion.

Answer 7

Step 4:

Evaluation of the Anteroposterior

Question 8

•Occasionally, the molar occlusion is Class II on one
side and Class I on the other.
•Angle called this a ________ depending on which was the Class II side.

Answer 8

Class II subdivision right or left,

Question 9

With the casts in occlusion, vertical problems can be described as:
•Anterior open bite.
•Failure of the incisor teeth to overlap.
•Anterior deep bite.
•Excessive overlap of the anterior teeth.
•Posterior open bite.
•Failure of the posterior teeth to occlude, unilaterally or bilaterally.

Answer 9

Step 5:

Evaluation of the Vertical Plane of Space

Question 10

A patient with a skeletal open bite will
usually have an anterior open bite
malocclusion that is characterized by:
• Excessive eruption of posterior teeth.
• Downward rotation of the mandible.
• Downward rotation of the maxilla.
• Normal (or excessive) eruption of anterior teeth.

Answer 10

Long Face Syndrome

Question 11

What are the 4 components of long face syndrome?

Answer 11

• Excessive eruption of posterior teeth.
• Downward rotation of the mandible.
• Downward rotation of the maxilla.
• Normal (or excessive) eruption of anterior teeth.

Question 12

What are the 6 clinical features of long face syndrome?

Answer 12

• Increased LAFH.
• Decreased PFH.
• Increased gingival display.
• Incompetent lips.
• AOB.
• Weak musculature.

Question 13

With the completion of a _________, the diagnostic phase of diagnosis and
treatment planning is completed, and the more subjective process of
treatment planning begins.
•Thorough diagnostic evaluation means that all problems have been identified
and characterized at this stage.

Answer 13

problem list

Question 14

The objective in _________ is to design the strategy
that address the problems while maximizing benefit and
minimizing cost and risk to the patient.
•Interaction with the patient and parent, so that they are
involved in the decisions that lead to the final plan, is the key
to informed consent.

Answer 14

treatment planning

Question 15

•Interaction with the patient and parent, so that they are
involved in the decisions that lead to the final plan, is the key
to ________

Answer 15

informed consent.

Question 16

Arranging a list of the _____ which need to be achieved

based on the problem list.

Answer 16

“ goals ”

Question 17

_______ should consider:
•Patient Inputs.
•Predictability and Complexity of Treatment.
•In a systematic fashion.
•From the most important item to the least.
•Doable.

Answer 17

Treatment objectives

Question 18

•Failure of the incisor teeth to overlap.

•

Answer 18

Anterior open bite.

Question 19

•Excessive overlap of the anterior teeth.

Answer 19

Anterior deep bite.

Question 20

•Failure of the posterior teeth to occlude, unilaterally or bilaterally.

Answer 20

Posterior open bite.

Question 21

______ is nothing but gathering:
•The most accurate finding .
•Classifying them in a systematic format.

Answer 21
