Chapter 67 - Mandibular and maxillofacial fractures Flashcards
Name the following structures in the figure below?
A. Coronoid process
B. Angular process
C. Mental foramina
D. Ramus of the mandible
What are your radiographic findings?
An oblique fracture is present through the body of the right mandible, extending caudal to the last
mandibular molar. This fracture is medially and ventrally displaced. No additional fractures are
identified. The temporomandibular joints are within normal limits.
What is your radiographic diagnosis?
Oblique right mandibular fracture
Which of the following statements is/are true?
a. Mandible fractures have a faster healing rate compared with maxillofacial fractures.
b. In the mandible maximal tensile stresses exist at the aboral surface.
A. A is true
B. B is true
C. A and B are true
D. A and B are false
D. A and B are false
Maximal tensile stresses exist at the oral or alveolar surface, and maximal compressive stresses exist
at the aboral surface.
Which of the following statements is/are true?
a. In order to the basic principles of fixation, mandibular proceeds as the first step, followed by
reconstruction of the medial, then lateral, maxillary buttress.
b. When an intraosseous wire is used as a fixation technique in case of a mandibular fracture,
the wire needs to maintain at least three twists after you cut it.
A. A is true
B. B is true
C. A and B are true
D. A and B are false
B. B is true
Which of the following statements is/are true?
a. Intraosseous wire is a good fixation technique for mandible and uncomplicated midfacial
skeleton fractures.
b. The stabilization wire is another term for a figure of eight wire pattern.
A. A is true
B. B is true
C. A and B are true
D. A and B are false
A. A is true
Name two forces that are neutralized by a second stabilization wire?
1: Shear
2: Rotational
What is the name of the plate in the figure below?
Martin miniplate (Walter Lorenz Surgical, Inc)
(Additional: an anvil (large arrow) and two circular prongs at the tip of the bending pliers (small arrows) are used to perform in-plane bending by inserting the circular prongs into two adjacent holes in the plate)
What is the name of the plate in the figure below?
DePuy Synthes miniplate (DePuy Synthes Vet)
What is the name of the plate in the figure below?
Advanced locking plate system (Kyon)
In case of a mandibular fracture: name two disadvantages of the use of an single locking plate
along the ventral mandibular margin instead of the use of two miniplates (one at the alveolar
border and a second at the aboral ventral bone margin)?
1: Biomechanically unfavorable position
2: Higher risk of damaging the tooth roots
