Final answer:
In dental implant surgery, the second stage typically involves placing an abutment post into the implant, which will later hold the replacement tooth.
Step-by-step explanation:
The implant surgery in discussion typically refers to a dental implant procedure, which is performed in several stages. During the second stage of surgery, an abutment post is typically placed into the implant. This post serves as a connector to eventually hold the replacement tooth, or crown, in place. The abutment can be made of various materials, but titanium is often used due to its strength and compatibility with the body. The abutment post is screwed into the implant and protrudes slightly above the gum line, where the crown will be attached.
