SAMMEND: Surgical arch bars (splints) are used in maxillofacial surgery as an 
         aid to intermaxillary fixation procedures. Two different types of    
         stainless steel arch bars, a solid bar and a silver-brazed bar, were 
         studied with regard to metal release in vitro. Arch bars were ligated
         to jaw models and immersed in 0.9% saline solution. The electrolyte  
         was analyzed for Ni, Cr, Fe, Cu, Zn, and Cd by atomic absorption     
         spectrophotometry on day 3, 10, and 28. The amounts of metal released
         from the brazed arch bar were 140-600 times higher than those rel    
         eased from the solid arch bar. Clinical implications are suggested.
