vertical bone resorption by as much as 70%. Platform switching and the horizontal component of biologic width Furthermore, by platform switching implants that are 3 mm apart or less or within 1.5 mm of the facial aspect of a thin buccal plate, the implant-abutment junction (IAJ) is shifted onto the implant platform away from the peri-implant bone, mitigating the deleterious impact of the inflammatory zone at the microgap of the implant-abutment junction on the bone, allowing for a reduction in the horizontal extent of bone loss.
