  1. بسم الله الرحمن الرحيم Dr. Kadhim Jawad

  2. TRAUMA FROM OCCLUSION & SPLINTING Dr. Kadhim Jawad

  3. The physiological adaptive capacity of the periodonteum to occlusal force Dr. Kadhim Jawad

  4. Response of PD tissue to increased occlusal force • Injury • Repair • Adaptive or remodeling of the periodonteum Dr. Kadhim Jawad

  5. 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. Dr. Kadhim Jawad

  6. Trauma from occlusion (TFO) Or occlusal trauma(OT) An injury to the periodonteum produced by occlusion . Dr. Kadhim Jawad

  7. Traumatic occlusion (TO) is an occlusion that produces injury to the periodonteum. Dr. Kadhim Jawad

  8. 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. Dr. Kadhim Jawad

  9. Acute occlusal trauma Dr. Kadhim Jawad

  10. Acute occlusal trauma clinically results in • Tooth pain. • Increased tenderness to percussion. • Increased tooth mobility. Dr. Kadhim Jawad

  11. 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. Dr. Kadhim Jawad

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

  13. Primary & Secondary O.T Dr. Kadhim Jawad

  14. Primary O.T. or TFO Abnormal occlusal force effect on normal periodonteum Dr. Kadhim Jawad

  15. secondary O.T. or TFO Abnormal or normal occlusal force effect on abnormal periodonteum Dr. Kadhim Jawad

  16. The effect of OT on periodontal disease initiation and progression Dr. Kadhim Jawad

  17. No effect on Gingiva ( blood supply) • Not cause gingivitis • Enhance bone resorption in periodontitis • Causes infra bony pocket • Delay healing after treatment

  18. Clinical & Radiograghic sings of O.T. alone • CLINICALLY • Tooth pain • Tooth tenderness • Tooth mobility Dr. Kadhim Jawad

  19. Radiographically • Increase the width of P.d.L. space . • Vertical bone defect. • Radiolucent and radio opaque areas in the bone. • Root resorption. Dr. Kadhim Jawad

  20. Pathologic tooth migration Dr. Kadhim Jawad

  21. Periodontal splinting Dr. Kadhim Jawad

  22. 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). Dr. Kadhim Jawad

  23. Important note • Always remember that splinted teeth need a special instruction on oral hygiene measures to keep the marginal gingival free from irritating material (plaque and calculus) it is achieved by using • The interdental brush • The super floss especially in the posterior regions Dr. Kadhim Jawad

  24. Thank You Dr. Kadhim Jawad
