Correct answer: A — Pendulum appliance
The pendulum appliance (Hilgers pendulum) is an intraoral fixed appliance that distally tips and moves maxillary first molars to create space without patient compliance (no headgear). It uses TMA springs attached to a Nance button for anchorage. Disadvantages include mesial tipping of premolars and distal crown tipping of molars. Alternatives for molar distalisation include the distal jet, headgear, and temporary anchorage devices (TADs/miniscrews).
