  • 1. Prosthodontics 3rd YearOCCLUSAL RELATIONSHIPS FOR REMOVABLE PARTIAL DENTURE Dr. Loreidys Castañeda
  • 2. OCCLUSIONFUNCTIONAL HARMONIOUS
  • 3. CAUSES OF FAILURE TO PROVIDE ANDMAINTAIN ADEQUATE OCCLUSION ON THE REMOVABLE PARTIAL DENTURE1. Lack of support for the denture base.2. Establishing occlusion in a single static jaw relation record.3. Unacceptable occlusal plane.
  • 4. • The influence of the remaining natural teeth is usually such that the occlusal forms of the artificial teeth must be made to conform to an already established occlusal pattern.
  • 5. ANALYSIS OF THE CORRECTION OF OCCLUSION OCCLUSAL DISHARMONY SATISFACTORY OCCLUSION RECORDING OF RECORDING OFCENTRIC RELATION ECCENTRIC JAW OR OCCLUSION RELATIONS CORRECTION OF OCCLUSAL DISCREPANCIES
