Profile: Ronvig Dental Mfg. A/S develops, produces and markets dental instruments. Our product aspiject is a self-aspirating injection syringe using a standard anaesthetic cartridge. It is manufactured using stainless steel. Its unique styling and design offers the ultimate in balance, feel and tactile control. Self-aspirating without pull-back minimizes the risk of needle tip movement. The dento-prep microblaster is used with aluminium-oxide powder for micro-roughening of porcelain, composite and metal surfaces prior to cementation in order to secure optimal bond strength. It is ideal for both intra-oral and extra-oral applications.
