Answer to Question #190

The correct answer is

The biggest problem with the design is that the major connector ends in the gingival sulcus of the anterior teeth. If the intent is to plate these teeth, the plating must cover the cinguli and extend interproximally up to the contact points. If plating is not desired, the border of the major connector must be at least 6 mm away from the gingival margins.
