How many components make up Passivity Plus™?
Four pieces in a compact, integrated design:
- Base body: Connects to multi-unit abutment; contains 5° internal taper
- Pivotable adjustable cap: Receives prosthesis cement; self-adjusts, then locks when torqued
- Screw: One piece; 5° body taper; smooth surface; creates cold weld
- Washer: Flexible element around screw head; key patent innovation
The inventor notes this was a significant engineering achievement: 'I worked very hard on it... to make all this mechanism, four pieces sitting in such a small part. The unique, and difficult development was the base’ resistance to sideways shift as the screw is tightened. The stress is centered due to the screw threading and the floating washer mechanism.’
