For crown and bridge alloys and pressable ceramics


SKU: N/A Category: Tag:


This high-performance, universal investment works equally well for all alloys and pressable ceramics. Its expansion range enables the technician to achieve optimal fit using the rapid or standard burnout technique. The robust bimodal nature of Formula 1 strengthens molds and promotes easier devesting when working on more fragile materials such as all-ceramic restorations. Using only a 15-minute benchset and 30-minute burnout, Formula 1 reduces processing time and increases lab productivity.
