Occlusal Trauma and Periodontium Flashcards
What is primary occlusal trauma?
Injury to periodontium of normal heigh as result excessive occlusal force
What is secondary occlusal trauma?
Injury to periodontium of reduced height at result of excessive occlusal force
Aetiology of occlusal trauma?
Premature contacts Parafunctional habits Drifting following loss/perio Loss posterior teeth Occlusal discrepancy
What are clinical features expect to see if occlusal trauma?
Mobility Fremitus Tooth migration Tenderness and pain TSL
What is fremitus?
Movement of teeth subjected to occlusal forces
Radiographic features of occlusal trauma?
PDL widening
In secondary occlusal trauma = bone loss
Two types of occlusal forces?
Lateral type force
Jiggling type force
When are jiggling type forces an issue?
In absence of inflammatory disease jiggling forces don’t affect supracrestal CT attachment and don’t cause pocket formation
Can cause PDL widening/ mobility
What can tooth mobility be?
Physiological
Pathological
What is physiological tooth mobility?
Increased occlusal load and PDL widening in absence inflammatory disease
What is pathological tooth mobility?
Associated w/ active progressing inflammatory perio disease
Management of teeth w/ physiological movement?
Occlusal adjustment
Splint adjacent teeth
How manage teeth w/ pathological movement?
Maintain tooth and tx inflammatory perio disease
Consider splint reduce mobility
XLA if poor prognosis
Different types of splints which can be used?
Temporary
Semi-permanennt
Permanent
Fixed or removable
When are removable splints indicated?
Pt w/ TMD/parafunctional habits
