Final answer:
The proper sequence for endosteal implant placement is Incision, Drilling, Implant Placement, Suturing.
Step-by-step explanation:
The correct sequence for endosteal implant placement from start to finish is Incision, Drilling, Implant Placement, Suturing. This process begins with an incision in the gum tissue to access the bone, followed by drilling a hole in the jawbone where the implant will be anchored. After the implant is securely placed in the drilled hole, the site is sutured closed to allow for healing.
