Maxillary: 1. Occlusal · 2. Palatal · 3. Buccal — rotate the tip so it faces up.
Mandibular: 1. Occlusal · 2. Lingual · 3. Buccal — in the anterior area, include the incisal edge when scanning the occlusal surface.
Buccal pass: capture part of the occlusal surface at ~45°, then rescan at ~90°, avoiding the gingiva.
Moving soft tissue is the most common cause of scan errors — retract the lips, cheeks, and tongue throughout the pass. Move at a constant speed along the first (occlusal) path, and keep the scanner in contact when possible.
