Fig.5: The buccopalatal dimension (white line) of the socket is larger than the mesiodistal one.
The socket division and anatomy is similar to a case. But in this case, the septum and the buccal socket are chosen to be an recipient site, because the palatal socket is narrow mesiodistally and oblique buccopalatally (not ideal for restoration).
