# Frictional resistance of esthetic-coated archwires in with metal, ceramic and polycarbonate brackets

## TL;DR

This study compares friction levels between different bracket and wire combinations, showing that stainless steel brackets with coated wires offer the best orthodontic performance.

## Contribution

The study provides new empirical data on frictional resistance in esthetic-coated archwire systems with various bracket materials.

## Key findings

- Stainless steel brackets with coated NiTi wires showed minimum friction at 2.3 ± 0.2 N.
- Ceramic brackets with ceramic-coated NiTi wires showed maximum friction at 6.5 ± 0.5 N.
- Stainless steel brackets with coated wires are associated with better orthodontic outcomes.

## Abstract

The level of friction that occurs when aesthetic brackets interact with coated wires is of interest. The resistance values reached
their minimum point when stainless steel brackets used coated NiTi wires at 2.3 ± 0.2 N but reached their maximum point when
ceramic brackets applied ceramic-coated NiTi wires at 6.5 ± 0.5 N. Brackets made with stainless steel material combined with
coated NiTi wires produce superior orthodontic results according to the research. The increased friction caused by ceramic brackets
could possibly reduce the rate of tooth movement. The decision of proper wire-bracket pairs remains critical because it determines both
therapy results and cosmetic outcomes.
