The five factors affecting occlusal balance are condylar inclination, incisal guidance, occlusal plane inclination, the compensating curve and cuspal inclination. The inter-relationship of these factors may be described as Theilman’s formula. This program illustrates how these five factors inter-relate in when designing the occlusion for any particular patient.

  • 2. Hanau’s Quint Five Factors Affecting Occlusal Balance Condylar Inclination Incisal Guidance Occlusal Plane Inclination Compensating Curve Cuspal Inclination
  • 3. Hanau’s Quint Inter-relationship of these five factors may be described by Theilman’s Formula In order to maintain a balanced occlusion: C = Condylar Inclination OccPlane x Incisal Guidance x Cuspal Inclination x CompCurve C=Balanced Occlusion
  • 4. C = Condylar Inclination OccPlane x Incisal Guidance x Cuspal Inclination x CompCurve
  • 5. C = Condylar Inclination OccPlane x Incisal Guidance x Cuspal Inclination x CompCurve
  • 6. When all five factors are in “balance” . . . C = Condylar Inclination OccPlane x Incisal Guidance x Cuspal Inclination x CompCurve
  • 7. . . .“Balance” is maintained in excursives C = Condylar Inclination OccPlane x Incisal Guidance x Cuspal Inclination x CompCurve
  • 8. When Incisal Guidance is increased . . . C = Condylar Inclination OccPlane x Incisal Guidance x Cuspal Inclination x CompCurve
  • 9. When Incisal Guidance is increased . . . C = Condylar Inclination OccPlane x Incisal Guidance x Cuspal Inclination x CompCurve
  • 10. . . . Posterior Disclusion will occur unless . . . C = Condylar Inclination OccPlane x Incisal Guidance x Cuspal Inclination x CompCurve
  • 11. . . . Occlusal Plane Inclination, . . . C = Condylar Inclination OccPlane x Incisal Guidance x Cuspal Inclination x CompCurve
  • 12. . . . Cuspal Inclination, . . . C = Condylar Inclination OccPlane x Incisal Guidance x Cuspal Inclination x CompCurve
  • 13. . . . or Compensating Curve is Increased C = Condylar Inclination OccPlane x Incisal Guidance x Cuspal Inclination x CompCurve
  • 14. Increasing the Compensating Curve C = Condylar Inclination OccPlane x Incisal Guidance x Cuspal Inclination x CompCurve Correcting Posterior Disclusion by
  • 15. Monoplane Denture Occlusion C = Condylar Inclination OccPlane x Incisal Guidance x Cuspal Inclination x CompCurve Use of Flat Plane or 0º Posteriors
  • 16. Monoplane Denture Occlusion C = Condylar Inclination OccPlane x Incisal Guidance x Cuspal Inclination x CompCurve Use of Flat Plane or 0º Posteriors
  • 17. Monoplane Denture Occlusion C = Condylar Inclination OccPlane x Incisal Guidance x Cuspal Inclination x CompCurve Use of Flat Plane or 0º Posteriors
  • 18. Monoplane Denture Occlusion C = Condylar Inclination OccPlane x Incisal Guidance x Cuspal Inclination x CompCurve Posterior Disclusion with 0º Teeth
  • 19. May be corrected by “Balancing Ramps” C = Condylar Inclination OccPlane x Incisal Guidance x Cuspal Inclination x CompCurve Posterior Disclusion with 0º Teeth
  • 20. Essentially increases Compensating Curve C = Condylar Inclination OccPlane x Incisal Guidance x Cuspal Inclination x CompCurve Posterior Disclusion with 0º Teeth
  • 21. Alternate solution to maintaining “balance”. . . C = Condylar Inclination OccPlane x Incisal Guidance x Cuspal Inclination x CompCurve Posterior Disclusion with 0º Teeth
  • 22. . . . is to decrease Incisal Guidance C = Condylar Inclination OccPlane x Incisal Guidance x Cuspal Inclination x CompCurve Posterior Disclusion with 0º Teeth
  • 23. . . . is to decrease Incisal Guidance C = Condylar Inclination OccPlane x Incisal Guidance x Cuspal Inclination x CompCurve Posterior Disclusion with 0º Teeth
  • 24. . . . is to decrease Incisal Guidance C = Condylar Inclination OccPlane x Incisal Guidance x Cuspal Inclination x CompCurve Posterior Disclusion with 0º Teeth
  • 25. . . . is to decrease Incisal Guidance C = Condylar Inclination OccPlane x Incisal Guidance x Cuspal Inclination x CompCurve Posterior Disclusion with 0º Teeth
  • 26. is minimized by minimizing Incisal Guidance C = Condylar Inclination OccPlane x Incisal Guidance x Cuspal Inclination x CompCurve Posterior Disclusion with 0º Teeth
  • 27. Balancing Ramp Addition (as before) or . . . C = Condylar Inclination OccPlane x Incisal Guidance x Cuspal Inclination x CompCurve The minimal disclusion can be corrected by
  • 28. . . . an increase in Occlusal Plane Inclination C = Condylar Inclination OccPlane x Incisal Guidance x Cuspal Inclination x CompCurve The minimal disclusion can be corrected by
