Hypothese(s) for growth control is(are):

(b) genetic control acts on cartilage only.
(c) genetic control acts on soft tissue only.
(d) all of the above.***
Win Naing #261
If a patient has exhibited maxillary undergrowth in a vertical dimension along with a compensating acute angle of the mandible, what facial pattern will be seen?
a) dolicofacial pattern
b) distofacial pattern
c) mesofacial pattern
d) brachyfacial pattern ***
Lauren Fleischner, #227
A dolicofacial pattern is characterized by
A. Overgrowth in the vertical direction ****
B. Undergrowth in the vertical direction
C. Overgrowth in the horizontal direction
D. Undergrowth in the horizontal direction
Kevin Andrus #200
A class III occlusion can be an outcome of which of the following situations?
A. Posterior placement of the maxilla and maxillary dentition
B. Anterior placement of the mandible and mandibular dentition
C. Anterior placement of the mandibular dentition and normal placement of the mandible
D. All of the above *****
Gregory Werner #298
Which of the following is false:
A) The timing of growth of the mandible follows the general growth pattern
B) The timing of growth of the maxilla follows neural tissue growth pattern
C) At age 4 maxillary growth is more advanced than mandibular growth
D) At age 10 mandibular growth is more advance than maxillary growth***
Melanie Ngov #266
What is a possible treatment for mandibular undergrowth?
A) Chin Cup
B) Low Local head gear
C) Functional Appliances **
D) Cervical Head gear
-Duy Ly #220
Palatal expansion is a common maxillary growth modification appliance used in orthodontic treatment. It applies the _______ force to the palatal suture and correct the ________ plan deficiency of the maxilla.
a) upward, vertical
b) backward, horizontal
c) lateral, transverse *
d) backward, horizontal
Nini Chaichanasakul #211
Which of the following structure in the maxilla is relatively easy to modify?
a. Periosteum
b. Soft tissue
c. Suture *
d. Cartilage
Mi Jin Kim #244
Which of the following is incorrect with regards to the timing of growth modifications?
A. Girls experience puberty earlier than boys and so earlier growth modifications for girls are often warranted.
B. The maxilla follows the growth of neural tissue which means it has relatively high growth at age 5 to 8 and then tapers down. Therefore maxillary growth modifications should be performed earlier than later.
C. Mandibular growth follows the growth of general tissue and peaks around age 5, levels off, and peaks again after puberty.
D. At age 5 the mandible has a higher growth rate than the maxilla.**

Which of the following is FALSE:
A) Maxillary growth follows neural growth.
B) Mandibular growth follows general growth.
C) Orthodontic treatment is often aimed to occur at the peak of a child's growth spurt.
D) Male growth spurts tend to peak before female growth spurts.***

Your 5 year old patient has a mandible that looks shifted to the right and the maxilla is smaller than what it should be in a 5 year old. Which of the following is most probably true?
A)The patient has a unilateral cross-bite as a result of maxillary undergrowth
B) The patient has normal bite and the mandibular shift is unrelated to the maxillary undergrowth
C) The patient has bilateral cross-bite and in an attempt to get fossa contacts has shifted the mandible to one side resulting in a unilateral cross-bite appearance
D) The maxillary undergrowth has been compensated by mandibular undergrowth.
Answer: C: Pt has cusp/cusp contacts since his maxilla is small so he tries to get cusp/fossa contact by shifting the mandible to one side. In reality, this unilateral cross bite is a bilateral problem.

All of the following are types of facial growth patterns, except:
A. Dolicofacial

Vivien Lao
#251
Which of the following treatment is used to modify mandibular excess growth?
A) Functional Appliances
B) Cervical Head gear
C) Low Local head gear
D) Chin Cup *
Farinaz Bokhour
# 209
Which of the following are important considerations when making a orthodontic diagnosis?
A) Is the orofacial issue more on the maxilla or the mandible?
B) Is the orofacial issue more a skeletal or dental?
C) Is the issue an overgrowth or an undergrowth?
D) Is it a vertical vs horizontal or vs a transverse issue?
E) All of the above. ***
Question created by Jason Kung, #249
Which of the following statements concerning growth is incorrect?
A. The maxilla generally follows the growth of neural tissues
B. Mandibular growth occurs mostly during puberty
C. Patients who have completed growth are still candidates for growth modification to correct dentofacial abnormalities***
D. None of the Above
Jennifer Egli #224
A chin cup appliance is used to do which of the following?
a.) protect the chin when playing tackle football
b.) encourage bone remodeling to decrease mandibular excess
c.) expand growth of the palate
d.) in order to drink fluids from a cup without using one's hands
submitted by Andrew Chen #214
Israel Trujillo #298
