Steps in repair of provisional restorative materials.

Place the fractured pieces of the sample in the mould as fit. Mark a line on each side at a distance of 1mm from the fracture point. Trim the sample at these lines. The edges to be repaired are at 2mm distance from each other. Mark a point along the length of the sample equal to the thickness (2.5mm). Draw a line parallel to the end at this pointJoin the upper end of this line and the lower end of the finished edge to be repaired Trim the angle freeh and to get a 45° bevel.
