3.As patients have become more and more demanding regarding the aesthetic as a biocompatible aspects of their dental restorations, a material which the name is heat-pressing system for all-crown dentistry was developed by Wohlwend at the dental institute, Zurich University in the mid-1980s.
5.Vapour is carried by boiler on craft -- the equipment that use steam -- drain pipe net -- catchment canister -- water supply pump prevents cavitation plant -- deoxidize implement or boiler, comprise condenser water of airtight type vapour to reclaim circulatory system, condenser water collects coal tub is belt pressing, condenser water reclaims temperature is more than 100 ℃ , be close to the saturated temperature of pressure of scanty water of the equipment that use steam, the system that shut type pays attention to vapour to carry the type selecting of drain valve of the system, equipment that use steam; Condenser water assemble and feeding scientific design, optimize type selecting and stair to match, use can system, more than heat reclaims more scientific and reasonable, achieve first-rate to use can efficiency.
