The design in Fig.4 overcomes these 2 shortcomings.  The center of the implant is 5 mm from the neighboring tooth.  Mesially there is more bone support (*), whereas distally bone graft is necessary (red circles).  There is still enough space between the two implants; the minimum is 3 mm.

Care should be taken to make sure that bone expansion and implant placement do not shift distally, because there is more bone mesially than distally.
