Overview

OA-0305 is an alternate catalog ID for elastic power chain. Full clinical and technical details: see Power chain.

Common variants & modifications

• Short-link: links close together; maximum force; rapid space

closure

• Medium-link: standard link spacing; balanced force
• Long-link: widest spacing; lightest force; finishing and

consolidation

• Colored power chain: available in all colors; same mechanics as

natural

• Figure-8 variant: alternating figure-8 pattern for combined

ligation and force delivery
