Study Notes

Polyvinyl Siloxane (PVS) Addition Silicone

Hydrophilic property allows for best detail reproduction in a moist environment.
High flow properties enable intimate contact with transfer coping.
Rigidity secures implant coping position, allowing tissue contours to be "frozen".

Hybrid Abutments

Lithium disilicate seated on a Ti base (hybrid) is one type of hybrid abutment.
Zirconia seated on a Ti base (hybrid) is another type, milled from E.max or zirconia blocks and bonded to a titanium base by a resin cement in the laboratory.
Hybrid abutments have a snap-on cap available in different colors, each determining a different size (e.g., yellow code for Narrow Coping, purple code for Regular Coping).

Advantages and Disadvantages

Accurate replication of implant angulations is an advantage of hybrid abutments.
Rotation of coping during analogue is a disadvantage of hybrid abutments.
