In vitro evaluation of aligner attachment bond strength on enamel, composite, and lithium disilicate surfaces using different resin composites
The aim of this study was to evaluate the shear bond strength (SBS) of aligner attachments bonded to enamel, composite-restored, and lithium disilicate glass-ceramic surfaces using flowable and high-viscosity resin composites. Ninety extracted premolars were divided into three groups (n = 30) according to surface type:...
