Questione giuridica chiave
Whether the tooth injury resulted from an accident within the meaning of social insurance law
Decisione estratta
Yes. The collision with the temporary sign and the impact against it constituted an unusual external factor and thus an accident.
Motivazione estratta
The factual findings of the cantonal court were binding and not manifestly incorrect. Even apart from alleged stumbling, the striking of the mouth/tooth against a temporarily erected sign is a distinctive, non-routine additional event that satisfies the accident requirement.
