Increased concentrates fed

Class 1 Malocclusion

Arcades approximately aligned but individual tooth malpositioned in any plane Tooth overgrowth = sharp enamel points, steps, waves, hooks Rotation or tipped

Sharp enamel points lead to what?

Maxilla = buccal points, lacerations Mandible = lingual points, lacterations

Malocclusion type?
