When fitting the metallic frame of a porcelain-fused-to-metal dental bridge, it was determined that in the central occlusion the frame is in a contact with the antagonist teeth. It reaches the ledges of the abutment teeth and is 0.3 mm thick. What tactics should a dentist choose?

Answer options

1. Obtain an impression with the frame fitted into the oral cavity
2. File down the metallic frame in the areas of its contact with the antagonist teeth
3. Determine the areas that prevent normal installation of the dental bridge.
4. Send the frame to the next laboratory stage of the denture-making
5. Complete the preparation of the abutment teeth and make a working impression
