Abbreviation AP stands for what in major connectors?

• A. Antero-posterior palatal strap
• B. Anterior palatal strap
• C. Antero-posterior plate
• D. Anterior palatal plate

Answer: (A)

An AP major connector is Antero-posterior palatal strap. This design uses both an anterior and a posterior palatal strap that are connected to span the palate, providing rigidity while offering less palatal coverage than a full palatal plate. It’s chosen when you need a stable connector but want to minimize tissue coverage—such as when a torus or gag reflex makes a full plate undesirable. The other options describe plates or a single anterior strap, which do not match the AP configuration.
