Restorative Art 2 Test 2 Flashcards
The comparative size of the length of the nose to the width of the nose as indicated by its bony skeleton.
Length of nose using bony skeleton combined with the width
nasal index
3 racial classifications for the nose
- Leptorrhine
- Mesorrhine
- Platyrrhine
one that is shorter in length. Is more broad in width and has MINIMUM PROJECTION. Usually has implications of Africa.
Platyrrhine
one that is moderate in length and width. Medium broad and also medium low bridge. Usually has implications of Asia.
Messorhine
one that is fairly long in length and narrow in width. Considered to be high bridged. Usually has implications of Europe/Western Europe
Leptorrhine
3 Basic Forms….Types or Styles of Nose Profile Forms
- straight
- convex
- concave
Greek/Greecian Form. Most common profile
straight
Pug. (AKA- Snub, Infantine, Retrousse) Typically able to see into nostrils more easily
concave
Roman/Aquiline Form. “Hooked Nose” Curved as the beek of an eagle.
convex
anatomy of the nose
nasal bones
nasal cavity
nasal spine of the maxilla
major cartilages
major cartilage of the nose
- septum (one)
- superior lateral cartilage (two)
- inferior lateral cartilage (two)
vertical cartilage of the nose, divides nasal cavity into two chambers. gives almost all the projection
septum
cartilage that meets with nasal bones
superior lateral cartilage
long anterior ridge of nose. Extends from inferior margin of forehead to greatest projection near base of the nose (at tip)
dorsum
parts of the nose
- dorsum
- root
- bridge
- wings
- columna nasi
- anterior nares
- sides of nose
- protruding lobe of nose
the dorsum is composed of….
- root
- bridge
- lobe
- tip
concave dip directly inferior to forehead…just below the glabella
root
spherical area forming inferior portion of dorsum. joins wings of nose and also the columna nasi. includes tip of nose.
lobe
lobe is also known as…
protruding lobe
the portion of lobes that join wings of nose…
lateral lobes
most inferior part of the nose
columna nasi
raised support that spans to areas. arched portion of the nose supported by the nasal bones
bridge
Termination point of maximum forward process (projection)
tip
external nostril openings…located posteriorly to the base of the nose
nares
lateral walls of nose
side of nose
base of nose is composed of…
- underside of protruding lobe
- inferior margins of wings of nose
- columna nasi
- nares
the mouth tends to be…
asymmetrical
boundaries of the mouth…
from base of nose…
to top of chin….
bound laterally by nasal labial folds
when closing the mouth there should be a gap between the teeth about the thickness of a ______
dime
the mouth is the center of….
expression
the postmortem adjustment of the ______ and ______ greatly affect the general appearance of the face.
jaws
lips
projection of the jaw or jaws beyond the upper part of the face.
Prognathism
types of prognathism
- maxillary
- mandibular
- dental
- alveolar
- infra-nasal
the base of the nasal cavity protrudes abnormally. Not only does it affect the base of the nasal cavity, it also affects the upper lip area. Looks like maxilla has protrusion as well as upper lip.
Infra-Nasal prognathism
the sockets of the teeth protrude. Typically, it causes the same degree of protrusion in both lips. (Aunt Belle)
Alveolar prognathism
the teeth themselves are inserted at an oblique angle. “Buck teeth” It will give the appearance of a receding chin. (may cause more difficult in closing lips)
dental prognathism
protrusion of inferior jaw…includes the chin. Goes well beyond the medium of the lip. Sometimes referred to as a “bulldog jaw” (Craig)
mandibular prognathism
the superior jaw protrudes…protrusion of the body of the maxilla. Projection is Anterior & Lateral
maxillary prognathism
parts of the mouth
- Superior Integumentary Lip
- Inferior Integumentary Lip
- Mucous Membranes
- superior mucous membrane (upper lip)
- inferior mucous membrane (lower lip)
- weather line
- medial lobe
- line of closure
skin portion of the upper lip. From attached margin of upper mucous membrame (the red lip area) to base of the nose.
Superior Integumentary Lip
visible red surface of the lips (upper red lip & lower red lip) lower red lip usually lies posteriorly to the upper red lip. The width of the lower lip is less than the top lip, tucks beneath the upper lip at the corners.
Mucous Membranes
skin portion of the lower lip. From attached margin of lower mucous membrane and extends down to labial mentus sulcus.
Inferior Integumentary Lip
The two red lips (even on the same person) are not identical in ________. In many cases the upper lip is less ______ than the other…even may be changes in color along the _______ of the lip.
color
red
width
tiny prominence on the mid-line of the superior mucous membranes
Medial Lobe
The corners of the mouth are verically aligned with the ______________________.
center of the eye
