Which major connector is most commonly used on the maxilla for a patient with a Class III short edentulous span?

• A. Palatal strap
• B. Palatal plate
• C. Lingual bar
• D. Palatal extension

Answer: (A)

Choosing a major connector for the maxilla hinges on providing rigidity across the arch while keeping palatal coverage to a minimum. For a Kennedy Class III situation with a short edentulous span, the palatal strap is the best fit. It’s a narrow yet rigid connector that spans between the remaining teeth across the palate, giving the cross-arch stability needed without the bulk of full palatal coverage. This minimizes bulk and tissue coverage, reducing gagging and irritation and preserving tongue space, which is especially important when the missing segment is short. In contrast, a palatal plate covers a large area of the palate and is more bulky, typically reserved for longer spans or when more load distribution and tissue coverage are required. Palatal extension is even more extensive and bulkier, also suited to longer edentulous areas. The lingual bar is a mandibular option, not applicable to the maxilla.
