Publisher's Synopsis
Elastomeric chains are polyurethane copolymers frequently used in orthodontic operations due to their versatility. They are effective, colorful, and comfortable for patients. Since the 1960s, elastomeric chains have been employed in orthodontic therapy for widespread space closure, midline correction, extraction space closure, and relocating impacted teeth. Andreasen and Bishara were pioneers in describing how these elastic chains could be used to close minor gaps between teeth.Due to their viscoelastic qualities, elastomeric chains are subject to force decay over time. This force decay is influenced by several factors, including the temperature within the oral cavity, fluctuations in pH levels, the presence of free radicals, and the use of mouthwashes. These factors collectively contribute to the degradation of the force exerted by the chains.
