Final answer:
The correct sequence for implant placement is 1, 2, 3.
Step-by-step explanation:
The correct sequence for implant placement from start to finish is:
- The titanium implant is surgically embedded into the bone.
- The abutment post or cylinder attaches to the artificial tooth.
- The titanium abutment screw is screwed into the implant after osseointegration of the implant and during stage II surgery.
So, the correct sequence is A) 1, 2, 3.
