RESTORATION OF THE WORN DENTITION Flashcards
PATHOLOGIC WEAR OCCURS WHEN THE PROCESS
OF PHYSIOLOGICWEAR IS ACCELERATED BY
— FACTORS AND
FREQUENTLY IT IS
— AND A VARIABLE
PHENOMENON.
EXOGENOUS OR ENDOGENOUS
MULTIFACTORIAL
THE EXCESSIVE WEAR OF JUST ONE TOOTH, OF
EXTENSIVE RESTORATIONS OR OF THE FULL
DENTITION HAS BEEN ASSOCIATED TO:
- — OATHE OPPOSING TEETH
- INCLINATION OF THE TEETH TO A CONTACT THAT HAS BEEN —
- REDUCTION OF THE — DIMENSION
- SOME AUTHORS ALSO BELIEVE THAT IT CAN BE A CONTRIBUTING FACTOR IN — DISORDERS.
SUPRAERUPTION
ERODED
VERTICAL
TEMPOROMANDIBULAR
ETIOLOGY OF WEAR
(6)
congenital anomalies
attrition
loss of posterior vertical support
abrasion
erosion
abfraction
DETERMINING THE TYPE OF
WEAR PRESENT
in the initial interview
a detailed review of the medical history, diet and an evaluation of the presence of environmental factors and patient habits should be done
ETIOLOGIES OF MECHANICAL
WEAR
(5)
loss of posterior support
premature occlusal contacts
bruxism
inadequate brushing technique
parafunctional habits
CHARACTERISTICS OF MECHANIC WEAR
(2)
presenceof wear facts with a well defined loss, that coincides on the articulated models
the pattern of the wear facets should be analyzed because they tend to occur in predictable places
GREATEST WEAR ON ANTERIOR TEETH
COMPARED TO POSTERIOR TEETH:
(3)
posterior support is inadequate or unstable
loss of posterior teeth
premature occlusal contacts
PROGRESSIVE WEAR GREATER ON ANTERIOR
TEETH:
(VERRET 2001)
(1)
it can be the result of bruxism
WEAR ON THE BUCCAL SURFACES OF
PREMOLARS AND CANINES:
(1)
is can be the result of excessive brushing or an inadequate brushing technique
WEAR ON THE INCISAL OR OCLUSAL
SURFACES:
(1)
usually due to parafunctional habits
ETIOLOGY OF CHEMICAL WEAR
(6)
chronic vomit
sucking of citric fruits
consumption of acidic drinks and foods
medicines with an acid pH
abuse of certain drugs
environmental factors
CHARACTERISTICS OF
CHEMICAL WEAR
presence of —

in most cases there are no — or changes in —
the wear facets done have a defined —
amalgam islands
grooves and fossae
hypersensitivity

periphery
CHEMICAL ETIOLOGY
GREATER LOSS OF DENTAL STRUCTURE
ON ANTERIOR SURFACES THAN ON
POSTERIOR SURFACES:
(2)
the more common cause is chronic vomit
sucking on citric fruits
GREATER LOSS ON POSTERIOR SURFACES
THAN ON ANTERIOR SURFACES:
(3)
consumption of acidic foods or drinks
rinse with or retain acidic drinks in the mouth
chew the pulp of certain fruits
VARIABLE LOCATION AND MISCELANEOUS CAUSES:
medicines with an acid pH that have frequent contact with dental surfaces
abuse of the —
application of — to the oral mucosa
patients that are exposed to acidic —
ampetamine extasis
cocaine
vapors and aerosols
