In a two-part implant system, the transfer (micro gap) between the implant head and the abutment is placed away from the outer edge more to the inside by means of platform switching. The biological width of approx. 2.0 – 2.5 mm should therefore not reach downwards purely vertically, but be deflected to the inside and horizontally by the size of the offset of the abutment on the implant interface.
From a clinical perspective a more stable crestal bone level with less remodelling is hoped for. Currently, numerous studies on platform switching are being carried out at almost all renowned implant manufacturers.
All prowital implants have the same internal geometry which offers the chance of “platform switching”. Various prosthetic components are available for all indications. (Fig. 1). On the one side, this allows for a homogeneous, stable implant neck without indentations, and on the other side, the option of using abutments of different diameters (platform switching) (Fig. 2).
