Winter classification describes the angulation of impacted third molars relative to the long axis of the second molar: mesioangular, distoangular, vertical, horizontal, and inverted. Pell and Gregory classification describes the relationship to the ramus (Class I, II, III) and occlusal plane (Position A, B, C). Both are used together for complete assessment of third molar impactions.
