  1. TRAUMA FROM OCCLUSION & SPLINTING

  2. The physiological adaptive capacity of the periodonteum to occlusal force

  3. Response of PD tissue to increased occlusal force • Injury • Repair • Adaptive or remodeling of the periodonteum

  4. Remodeling is an effort to create a structural relation ship in which the force is no longer injurious to the tissue & this include: • increased vascularization. • Thickening of the P.d.L. • Angular defect in bone with no pocket formation. • mobile teeth.

  5. Trauma from occlusion (TFO) Or occlusal trauma(OT) An injury to the periodonteum produced by occlusion .

  6. Traumatic occlusion (TO) is an occlusion that produces injury to the periodonteum.

  7. Other than its effect on the Periodontal tissues Excessive occlusal force may result in 1.Functional defects in the muscle of mastication. 2.Painful spasm of the muscles of mastication. 3.Injury to the T.M.J. 4.Tooth wear.

  8. Acute occlusal trauma

  9. Acute occlusal trauma clinically results in • Tooth pain. • Increased tenderness to percussion. • Increased tooth mobility.

  10. If the cause of such trauma is eliminated healing will take place & if not then • Periodontal injury may be worse & change into necrosis with or without abscess formation. • Cementum wear. • The condition may become chronic.

  11. Chronic occlusal trauma • It is more common ,it occurs due to gradual change in occlusion, caused by • Tooth wear • Drifting • Extrusion of teeth • Habits

  12. current methods of stabilization • The Re-enforced resin splint for posterior teeth (it is used temporarly). • Acid-etch resin splint for anterior teeth. • The resin –bounded metal splint (Maryland prosthesis).
