Peri-Implant Bone Level Around Implants With Platform-Switched Abutments: Preliminary Data From a Prospective Study

The concept of platform switching appears to limit crestal resorption and seems to preserve peri-implant bone levels. A certain amount of bone remodeling 1 year after final reconstruction occurs, but significant differences concerning the peri-implant bone height compared with the nonplatform-switched abutments are still evident 1 year after final restoration. The reduction of the abutment of 0.45 mm on each side (5 mm implant/4.1 mm abutment) seems sufficient to avoid peri-implant bone loss.
