Although the buccal (Fig.1 (mesial view of the extracted tooth #15): B) root is larger than the palatal (P) one, the palatal socket is larger than the buccal one (Fig.2 white area) because of the bone loss of the former.  For better restoration, osteotomy (Fig.2 red line) is initiated in the buccal slope of the septum (S) so that the final osteotomy is in the middle of the whole socket (Fig.3 red box).  In fact a 3 mm stopper is not used because of the slope and the clumsy stopper.  Stopper would be indicated if the bottom of the bone were flat.
