Fig.10 (mirror view): After implant (I) and abutment (A) preparation, bone graft is placed in peri-implant gap, followed by collagen dressing (mainly palatally (P) and proximally). B: buccal. The abutment is quite short after preparation for an immediate provisional. The latter may be able to keep the soft tissue from covering the margin of preparation during temporization.
