Twenty patients were randomly assigned to receive either a platform-switched or platform-matched implant to replace a single maxillary anterior tooth. Primary outcome variables were the implant interproximal bone loss, facial recession, and papilla fill at 12 months. The platform-switched group showed crestal bone loss of 0.1 ± 0.3 (mesial) and 0 mm (distal) while the platform-matched group showed losses of 0.6 ± 0.5 mm (mesial) and 0.7 ± 0.7 mm (distal) (P < .05). Facial recessions for the platform-switched and platform-matched groups were 0.1 ± 0.3 mm and 0.4 ± 0.8 mm, respectively.
