Q

Classification of malocclusion

A

Classification based on the maxillary first molar. In cases where the first molar is missing, canine teeth are used.

ANGLE Class I | NEUTROOCCLUSION: The mesiobuccal cusp of the maxillary first permanent molar occludes with the mesiobuccal groove of the mandibular first permanent molar.

ANGLE Class II | DISTOOCCLUSION (overjet): The molar relationship shows the mesiobuccal groove of the mandibular first molar is DISTALLY (posteriorly) positioned when in occlusion with the mesiobuccal cusp of the maxillary first molar.

ANGLE Class III | MESIOOCCLUSION (negative overjet): The mesiobuccal cusp of the maxillary first permanent molar occludes DISTALLY(posteriorly) to the mesiobuccal groove of the mandibular first molar.

Q

Describe the Stranc and Robertson classification

A

Stranc and Robertson classification of nasal bone fractures.

Fractures are described as “Frontal” or “Lateral” depending on the direction of the force sustained, and based on the ‘plane’ based on the degree of the fracture.
