The special combination of fillers forms a material that is extremely durable and wear-resistant; making it ideal for Class I and II restorations yet highly polishable for use in all Class II, IV and V restorations. Alpha II® AP has optimal handling characteristics. The material can be easily manipulated without sticking to your instruments. Alpha II® AP contains fluorescence to provide a duplication of the natural tooth surface.
