Fig.5: immediately post implant (I: 8x17 mm tapered) placement; A: abutment; P: bone powder (graft)). The tissue-level implant is placed subgingivally (mesially); insertion torque is 15 Ncm.  The same diameter cylindrical implant with larger surface area may achieve higher insertion torque with supragingival margin.  The latter is easy for restoration.

Fig.8: 5 months postop.  The bone in the mesial socket appears to have fused with the native one.
