In Figure 1.3.2 1.3. 2, ∠ABC ∠ A B C is a reflex of 240∘ 240 ∘ or an obtuse angle of 120∘ 120 ∘ depending on how it is measured. What is dental occlusion? Dental occlusion refers to the way in which the teeth line up with each other as the jaw goes from open to closed. So malocclusion. Angle's Classifications of Occlusion 2.
