What technique is used during fabrication of a maxillary major connector to improve tissue contact and prevent food entrapment?

• A. Beading anterior and posterior
• B. Beading only anterior
• C. Smoothing only posterior
• D. Relief trimming

Answer: (A)

Beading the palatal margins where the major connector meets the tissue creates a raised, contoured edge that hugs the mucosa more closely. Doing this on both anterior and posterior areas yields a continuous, intimate contact across the palatal surface, forming a better seal and reducing spaces where food can accumulate. With anterior and posterior beading, the connector fits more uniformly to the tissue, distributing pressure evenly and minimizing food entrapment around the edges. Beading only anterior would leave the posterior area under-adapted; smoothing only posterior doesn’t improve the anterior edge seal; relief trimming reduces contact and can create gaps that trap food. Thus, beading both anterior and posterior best enhances tissue contact and helps prevent food entrapment.
