Lecture 1 Flashcards
What three types of problems occur with maloccluded teeth?
- Psychosocial
- Oral function
- Greater susceptibility to trauma, periodontal disease and tooth decay
T/F Sever malocclusion is typically viewed as a social handicap
True
What do you see with children with articulation disorders?
- Delete sounds
- Substitute sounds
- Add sounds
- Distort sounds
What is the major reason people seek orthodontic treatment?
-Minimize psychosocial problems
What is a physiologic occlusion?
- When a patient does not necessarily have an ideal class I occlusion
- It adapts to the stress of function and can be maintained indefinitely
What is pathologic occlusion?
-When a patient cannot function without contributing to the dentitions and the oral facial complexes destruction
How does pathologic occlusion manifest itself?
- Excessive wear
- TMJ problems
- Pulpal changes ranging from pulpitis to necrosis
- Periodontal problems
T/F In pathologic occlusion abnormal forces are placed upon the dentition which causes the teeth to respond orthodontically to these abnormal forces
True (Termed pathologic tooth movement)
How is TMD manifested?
-Pain in and around the TMJ
In a patient with a class II malocclusion the deep anterior bite places a distalizing effect on what?
-The mandible
What are the four large groups for TMD?
- Masticatory muscle disorders
- TMJ disorders
- Chronic mandibular hypomobility
- Growth disorders
What one TMD group can be treated with orthodontics?
-Masticatory muscle disorders
What is myofascial pain?
-develops when muscles are overly fatigued and tend to go into spasm
What is splint therapy used to help identify?
-If the malocclusion is a possible cause of the patients TMD
What teeth should the splint cover?
-All of the teeth
What is the goal of splint therapy?
-Create a bite plane where the patient can function by removing any abnormal occlusal interferences
T?F Malocclusion, particularly protruding maxillary incisors can increase the likelihood of an injury to the teeth
True
What are the odds that a child with untreated class II malocclusion will experience trauma to the upper incisors?
1 in 3
What can cross bites and traumatic occlusions cause?
- Extreme wear
- Gingival recession
- Bone loss on the misaligned teeth
T/F Cross bites don’t influence growth and stress on the TMJ
False
-They can also influence growth as well as cause stress on the TMJ
