Visualization of stress and strain related to removable partial denture abutments. 1978

J T White

The following conclusions are based on the conditions set forth in this investigation and apply to forces acting through a vertical direction of application only: 1. The unilateral removable partial denture produced no more stress than the bilateral removable partial denture. 2. The fully active Dalbo removable partial denture resulted in the greatest stressbreaking action. 3. The rigid Dalbo removable partial denture resulted in the least ridge displacement. 4. The rigid Dalbo removable partial denture resulted in the greatest stress concentrations in the distal abutment. 5. None of the attachments tested resulted in a distribution of the stresses along the edentulous ridge. 6. The use of two abutments (double abutments) resulted in greater stress concentrations in the distal abutment than the use of single abutments. 7. Forces in the single abutment were resisted along the long axis of the root. 8. Forces in the double abutments were resisted along the long axis of the distal abutment.

D003834	Denture Precision Attachment	A precision device used for attaching a fixed or removable partial denture to the crown of an abutment tooth or a restoration. One type is the intracoronal attachment and the other type is the extracoronal attachment. It consists of a female portion within the coronal portion of the crown of an abutment and a fitted male portion attached to the denture proper.
