Sulcus reproduction with elastomeric impression materials: A new in vitro testing method
Finger WJ et al. - The sulcus model is considered useful for screening evaluation of elastomeric impression materials ability to reproduce narrow sulci. All tested materials and techniques reproduced 200 micro m wide sulci to almost nominal depth. Irrespective of the impression technique used, IMP showed the best penetration ability in 50 and 100 micro m sulci. Double-mix techniques are more suitable to reproduce narrow sulci than single-mix techniques. [more...]
