title: Effects of platform switching on crestal bone around implants: a histomorphometric study in monkeys.
abstract: A number of human comparison studies and case series have demonstrated the effectiveness of using a platform-switched implant-to-abutment connection to prevent peri-implant bone loss and subsequent soft tissue loss. To compare the bone around platform-switched and nonplatform-switched connections, adjacent pairs of both connection types were placed in a one-stage surgical procedure on each side of the mandibles of three monkeys (Macaca fascicularis). Eight weeks after abutment connection, histomorphometric analysis showed that both vertical and horizontal alveolar bone resorption had occurred around the nonplatform-switched implants, whereas bone was maintained vertically and new bone formed horizontally around the platform-switched implants.
