Fig 2From: Alveolar bone changes following bi-maxillary vertical molars’ movements using clear alignersMolars’ intrusion and extrusion measurements. A), the red line represents the palatal plane (ANS to PNS): and the yellow line represents the intersection line between the palatal plane and the most superior bi-furcation point of maxillary molars’ teeth. B), the red line represents the mandibular plane (Me-Go): and the yellow line represents the intersection line between the mandibular plane and the most inferior bi-furcation point of mandibular molars’ teethBack to article page
