The Philosophy of Force Distrubution falls under what 3 schools of thought? |
Stress Equilization Physiologic Basing Broad Stress Distribution |
|
|
Stress Equalization meaning |
Stress Directors: The Simple Hinge
How we use simple hinges that connect to the distal extention portion to the actual tooth bound portion to Dissipate the Stress When patient bites down on posterior are, the hinge allows base to sink Downward RPI DESIGN/COMBO CLASP |
|
|
Physiologic Basing |
Instead of using Stress Directors, Record the anatomy of the edentulous ridge in the "Functional Form" ALTERED CAST TECHNIQUE A: Denture movement stimulates soft tissues D: Denture teeth are slightly above occlusal plane |
|
|
Broad Stress Distribution meaning |
Easier to understand Distribution to force to a larger area = prevents trauma to teeth and soft tissues A: Occlusal stimulation. multiple clasps distribute horizonatal stresses. Easier construction. Less relining/rebasing D: Patients complain about denture being too big. Risk of caries COVER HAMULAR NOTCH, COVER RMP |
|
|
What are some factors that influence the support of the distal extension base? |
Quality of Soft Tissue Type of Bone Design of Prosthesis Amount of coverage Anatomy of Denture-Bearing Area Fit of Denture Base |
|
|
Cancellous bone compared to Cortical Bone |
Cancellous bone is less resistant |
|
|
Using the Altered Cast Impression Technique, whats the 1st thing we should do? |
Make sure there is Tripod Stabilization on the Tooth-Borne portion so we can make a Custom Tray over distal extension portion |
