What is the purpose of scalloping the superior borders of lingual plating?

Scalloping the superior borders of lingual plating serves to minimize food accumulation beneath the plating. This design feature allows for better oral hygiene by preventing food particles from getting trapped, which could otherwise lead to discomfort, irritation, or periodontal issues for the patient. The scalloped contour creates a smoother transition between the plate and the tissues, helping to maintain oral cleanliness and comfort during the normal function of eating and speaking. By addressing the potential for food impaction, scalloping ensures that patients can more easily maintain their oral health while using the removable partial denture.
