Look at the maxillary framework shown, which uses two transverse metal straps — one anterior and one posterior — connected laterally. What is the classification of this maxillary major connector?

Correct answer: A. Anterior-posterior palatal strap (A-P strap)

• A. CORRECT — The anterior-posterior palatal strap (A-P strap) consists of two transverse straps connected laterally, leaving a central opening. It is indicated when a palatal torus is present or when Class III RPDs need rigidity with maximum tissue coverage minimized.
• B. The horseshoe (U-shaped) connector follows the lingual gingival margins in a U-shape without a transverse crossbar; it is used when the palate must be avoided but has poor rigidity.
• C. Full palatal coverage extends over the entire palate as one continuous plate — used for extensive tooth loss requiring maximum support.
• D. A single palatal strap is one transverse band across the mid-palate; the framework shown has two straps.
