All these goals can be achieved with dental implants. But their success depends on peri-implant bone level. Platform switching is a concept where smaller-diameter prosthetic component is connected to a larger-diameter implant platform to create an 90 degree step between the implant and abutment which results in peri-implant hard tissue stability with soft tissue and papilla preservation.
