Occlusal Trauama

Question 1

Primary Occlusal trauma

Answer 1

Exessive force on normal periodontium

Question 2

Secondary Occlusal trauma

Answer 2

Normal or excessive force on weakened periodontium

Question 3

Fremitis

Answer 3

vibrate when they move

Question 4

Infrabony pockets

Answer 4

Pocket depths are deeper than the crest of the bone

Question 5

Buttressing Bone

Answer 5

apatation result from occlusal trauma. Outgrowth of alveolar bone

Question 6

Changes from occlusal trauma can be related to:

Answer 6

1. changes in adaptaion
   or
2. extension of inflammation periodontal disease w/o occlusal trauma

Question 7

Responses to occlusal trauma

Answer 7

Widened PDL space or thickened radicular lamina dura

Question 8

Angular bone loss and furcations

Answer 8

Controversial and could be due to toothy and bony anatomy and progression of inflammatory periodontal disease

Question 9

Co-destruction theory

Answer 9

Occlusal trauma may be a co-destructive factor that alters the severity and pattern of inflammatory periodontal disease. Merges with bacteria reaction to create different pattern and severity of periodontal progression and change the pathway and cause issues like infrabony pockets.

Question 10

Advancing plaque front theory

Answer 10

Occlusal trauma has no role in severity and pattern of periodontitis

Question 11

Trauma from occlusion w/o periodontitis

Answer 11

Injury results in acute inflammation
PDL collagen destruction
cementum resorption
bone loss
NO attachment loss
Tooth may become mobil

Question 12

How to help with occlusal trauma

Answer 12

Occlusal therapy

Question 13

Reduced periodontium w/o periodontitis

Answer 13

Reduced but healthy and causes no further attachment loss. Occlusal therapy helps aid with problems

Question 14

Reduced periodontium and periodontitis and occlusal trauma

Answer 14

Supracrestal periodontitis with occlusal trauma lesion are independent processes so things dont get worse.

MUST control periodontitis first

Question 15

Reduced periotdontium with subcrestal periodontitis

Answer 15

conditions are established for co-destruction. Must control periodontitis first before occlusal therapy

Question 16

Methods of occlusal therapy: Reversible

Answer 16

night guard
extracoronal splints
muscle relaxants
muscle exercies

Question 17

Methods of occlusal therapy: Irreversible

Answer 17

Intracoronal splints
Occlusal adjustment by selective grinding
orthodontics
surgery

Question 18

Occlusal adjustmet by selective grinding: indications

Answer 18

periodontal occlusal trauma
post orthodontics
prior to extensive

Question 19

Occlusal adjustment by selective grinding: contraindications

Answer 19

severe malcocclusion
Non-ideal but tolerating occlusion
severe wear
patient in pain or no suitable end point

Question 20

When is occlusal therapy indicated?

Answer 20

when in conjuction with periodontal treatment when occlusal trauma is present
ESPECIALLY indicated prior to perodontal regenerative surgery
