Thornton appealed the ban last week after he was sanctioned for punching and injuring an unsuspecting opponent against Pittsburgh on Dec. 7. He knocked Brooks Orpik's feet from under him and landed gloved punches to his head.
Orpik was knocked unconscious and suffered a concussion.
Bettman heard Thornton's appeal at a hearing in New York last Friday. The commissioner's decision was announced Tuesday.
Under terms of the collective bargaining agreement, Thornton will forfeit $84,615.45. Thornton and the NHL Players' Association could still elect to appeal to a neutral arbitrator.
