ORTHODONTIC BRACKETS COMPRISING A FILLED AND FIBER-REINFORCED POLYMERIC MATERIAL |
摘要 |
<p>An orthodontic bracket includes a bracket base and an arch wire slot in the bracket base. The bracket base comprises a polymer resin that is reinforced with glass or ceramic fibers and/or a particulate filler (e.g., a glass spherical particle filler). The bracket may include a ligation cover, which may be 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 particulate filler provides substantially increased overall strength and durability while providing increased flexibility and toughness to the bracket.</p> |
