Introduction to orthodontics Flashcards
What is orthodontics?
Diagnosis & treatment of misaligned jaws and teeth
Orthodontics plays an important role in:
facial esthetics
What are the two main goals of orthodontics?
- Form-esthetics
- Function
List some components of the goal “form-esthetics” in orthodontics: (4)
- smile design
- facial harmony
- symmetry
- psychological well being
List some components of the goal “function” in orthodontics: (4)
- optimize occlusion
- best possible masticatory function
- breathing
- speech
Occlusal function enhancement:
- establish _____
- establish ____
- estbablish or normalize ____
- correct ____
- establish harmonious occlusal relationship in three planes of space
- establish anterior coupling
- establish or normalize the transverse dimension
- current antero-posterior and vertical discrepancies
For occlusal function enhancement, a goal is to establish harmonious occlusal relationship in the:
three planes of space
What type of coupling should be established through occlusal function enhancement?
Anterior coupling
What type of discrepancies are correcting though occlusal function enhancement?
antero-posterior & vertical discrepancies
What is established or normalized through occlusal function enhancement?
transverse dimension
Interdisciplinary care involves:
several specialties of dentistry
Interdisciplinary care requires:
careful planning
Interdisciplinary care starts with:
the end in mind
The result of interdisciplinary care is dependent on:
the team proficiency & the patient motivation
Dr. Angle;s definition of the correct occlusal & tooth position is based on the relationship of the ____ and _____ _____ in the ____ dimension
upper & lower permanent first molars; AP dimension
The _____cusp of the upper _______ is in occlusion with the _____ groove of the lower _____ and a full complement of teeth is present- Dr. Angle
Mesiobuccal cusp; first permanent molar; buccal groove; first molar
Dr. Angle’s Class I occlusion definition does not exclude:
malocclusion
What are the most frequent malocclusons?
Class I malocclusion
Class I malocclusions are present in:
70% of population
Malocclusions are present in three dimensions of space including:
- sagittal
- transverse
- vertical
Describe a class II occlusal relationship:
The upper first permanent molar is positioned mesially in relation to the lower first permanent molar
The upper first permanent molar is positioned mesially in relation to the lower first permanent molar
Class II malocclusion
Describe a class III occlusal relationship:
The upper first permanent molar is positioned distally in relation to the lower first permanent molar
The upper first permanent molar is positioned distally in relation to the lower first permanent molar
Class III malocclusion
What is the esthetic role of orthodontics in oral health?
Improve quality of life by improving facial appearance
What is the functional role (occlusal level) of orthodontics in oral health?
QOL by improving function and mastication
What is the functional role (sleep apnea) of orthodontics in oral health?
QOL improvement by improving breathing and sleep- multidisiciplinary approach
The functional role of orthodontics in oral health regarding temporo-mandibular care is:
Applicable to a small group of patients (10%)
