What is the sequence of treatment of a crestal bone defect simultaneously with implant placement?

Use drag & drop.

Covering the exposed implant surface and surrounding bone with autogenous bone particles
Covering the autogenous bone particles with a slow-resorbing bone substitute
Perforation of the cortical bone
Covering the area by a resorbable barrier membrane
Harvest of autogenous bone particles from the vicinity of the surgical site
Primary closure of the soft tissue with tension-free suturing
Implant placement with primary stability
