A Sliding Bridge Appliance for Space Closure
Volume 25 : Number 2 : Page 0 : Feb 1991
The distance between abutments--bridge span--has an important influence on the durability of fixed prostheses. Loading of the abutment and the bridge is more than proportional to the bridge length.1 T...

Effect of a New Bonding Agent on Bond Strength to Saliva-Contaminated Enamel
Volume 28 : Number 2 : Page 0 : Feb 1994
When a bond failure occurs during initial archwire placement, it is likely to be the result of moisture contamination of the bonding site.1,2 Both in vitro and in vivo studies have demonstrated that m...
