Questão jurídica principal
Whether the dental injury constituted an accident under Art. 4 ATSG, in particular whether an unusual external factor was proven.
Decisão extraída
The injury was not proven to result from an unusual external factor; the alleged foreign object remained unidentified, so an accident in the legal sense was not established.
Fundamentação extraída
A mere assumption that a foreign body caused the damage is insufficient. Because the appellant could not identify what he bit on, the decisive circumstance remained unproven. Medical findings cannot replace proof of the external factor, and the insured bears the risk of non-proof.
