Which of the following is a disadvantage of using a wrought wire combination clasp?

Which of the following is a disadvantage of using a wrought wire combination clasp?

• A. Extra steps in fabrication
• B. Distorted by patient's careless handling
• C. Distort with function
• D. Increased cost

Answer: (A)

Fabrication complexity is a key drawback of wrought wire combination clasps. The wrought wire portion is flexible and must be carefully shaped to provide reliable retention without causing trauma or overstressing the tooth. When it’s combined with a framework, this requires extra lab steps: precise bending and positioning of the wire, adapting it to engage labial or proximal undercuts, securing it to the metal framework, and often soldering or crimping. After those connections are made, finishing and polishing are needed to prevent tissue irritation and rough edges. All of this adds bench time and increases the chance of lab errors, making the overall fabrication more labor-intensive than standard clasps. Distortion from handling or use and cost concerns can be factors with flexible components, but the primary disadvantage specific to this clasp type is the extra fabrication effort required to create and properly fit it.
