Platform switching in implant dentistry involves using an abutment with a smaller diameter than the implant, leading to various advantages such as reduced crestal bone loss and better maintenance of biological width. This concept arose from an accidental finding and offers benefits over using abutments and implants of the same diameter. Key advantages include reduced bacterial microleakage, decreased perimplant bone stress, and improved emergence profile.

3. In simplest words platform
switching is when the abutment
diameter is smaller than implant
diameter.
It was an accidental finding due to lack of
armamentarium but was found that it has
many advantages as compared to same
diameter abutment
