Trauma From Occlusion With Teeth Flashcards
What is the difference between primary and secondary occlusal trauma?
Primary - excessive force on normal periodontium
Secondary - periodontium is already weakened
What are some clinical signs of possible occlusal trauma?
- Tooth mobility (esp functional)
- Tooth migration
- Infrabony pockets
- Buttressing bone
What are some possible radiographic signs of occlusal trauma?
- Widened PDL space and thick lamina dura
- Trabecular bone change
- Angular and furcation bone loss
What is the co-destructive theory?
Occlusal trauma may work to also increase severity and pattern of inflammatory periodontal disease
What is the advancing plaque front theory?
Occlusal trauma has no role in severity and pattern of inflammatory perio disease
T/F: If there is occlusal trauma without periodontitis, attachment loss will still be seen.
FALSE
What happens when there is occlusal trauma without periodontitis?
Causes injury to PDL collagen, cementum respoption, and bone loss.
Tooth may become mobile
If trauma from occlusion is seen with periodontitis, which should be addressed first?
Periodontitis
What is co-destruction?
Trauma from occlusion and periodontal inflammation are at the same site causing enhanced attachment loss
T/F: If a patient has trauma from occlusion and periodontitis there will always be advanced attachment loss.
FALSE
Only if co-destruction occurs
What are some reversible methods to treat occlusal trauma?
- Night guard
- Extracoronal splints
- Muscle relaxants
- Muscle exercises
What are some irreversible methods of occlusal therapy?
- Intracoronal splints
- Occlusal adjustment
- Ortho
- Orthognathic surgery
T/F: Occlusal trauma in the absence of periodontitis may be reversible and result in adaption.
TRUE
T/F: There can be attachment loss without periodontitis.
False
T/F: Periodontal disease must first be resolved for any repair to occur.
True
