Which component passes through soft tissue from the implant to the oral environment?

The component that passes through soft tissue from the implant to the oral environment is the pemucosal abutment or healing abutment. This component is specifically designed to protrude above the gum line, allowing for the connection between the dental implant beneath the gum tissue and the restorative elements that will interface with the oral cavity, such as crowns or dentures.

The pemucosal abutment serves several important functions. It facilitates the healing process after the implant is placed by allowing soft tissue to form around it, which helps establish a biological seal and contributes to the stability of the implant. Additionally, this abutment provides a support structure for the final prosthetic restoration, making it essential for proper function and aesthetics in the dental implant system.

Other components such as the implant body are embedded within the bone and do not extend through the soft tissue to the oral environment. The fixation screw is used primarily to secure the abutment to the implant and also remains under the gum tissue. The cover screw is placed over the implant during the healing phase to protect it from contamination but is removed before placing the abutment. Therefore, the pemucosal abutment stands out as the key component that connects the oral environment to the underlying implant structure.
