You should avoid any composites and ethyl methacrylates like Trim or Snap. Those materials only have a semi-chemical bond to the provisionals material.
When repairing broken provisionals chairside, only methyl methacrylate should be used. The customer should remove the glaze by roughing up the surface with a coarse bur. Then apply cold cured methyl methacrylate to the surface.
