The whole reason the uchiha clan were suspected of the nine tails attack is because of the well known fact the sharingan can supress the bijuu. Sasuke entered the tailed beast dimension within naruto's conciousness the same way orochimaru did. Just an unexplained plot event. Just like how kakashi occasionally sees what is happening through obito's sharingan and vice versa. Im not saying every uchiha can but the village has more than enough sharingan users to supress the bijuu.
