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. increased vascularization. Thickening of the P.d.L.
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. is an occlusion that produces injury to the periodonteum.
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. Abnormal occlusal force effect on normal periodonteum
Primary O.T. or TFO
Abnormal occlusal force effect on normal periodonteum
Dr. Kadhim Jawad

15. Abnormal or normal occlusal force effect on abnormal periodonteum
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
