SELF-LIGATING ORTHODONTIC BRACKETS COMPRISING A FILLED AND FIBER-REINFORCED POLYMERIC MATERIAL |
摘要 |
<p>A self-ligating orthodontic bracket includes a bracket base, an arch wire slot in the bracket base, and a ligation cover. The bracket base and the ligation cover comprise a polymer resin reinforced glass or ceramic fibers, and further comprising a particulate filler. The cover is hingedly connected to the bracket base and rotatable relative to the bracket base between an open, non-ligating position and a closed, ligating position. The combination of reinforcing fibers and filler (e.g., spherical glass particles) provides substantially increased overall strength and durability while providing increased flexibility and toughness in the region of an optional hinge connection between the ligation cover and the bracket base.</p> |
