Adhesive bond strength control for orthodontic brackets. |
摘要 |
<p>Ceramic orthodontic brackets are bonded to teeth with dental adhesive. Each bracket has a silica-containing layer on the tooth facing base of the bracket. A silanation layer is also applied to the base. The silanation layer is deposited from a solution containing a first silane coupling agent reactive with organic resin in the adhesive and a second silane coupling agent having a non-reactive organic group. Collectively the silanes occupy all of the silanation sites on the silica-containing substrate. By controlling the ratio of reactive and non-reactive silane coupling agents, the bond strength between the substrate and the adhesive can be controlled. A set of ceramic orthodontic brackets can have uniform force of removal by varying the proportions of silane coupling agents on the brackets.</p> |
