DOI: 10.11607/prd.4243, PubMed ID (PMID): 31449577Pages 669-674, Language: EnglishLowy, Jeremy / Kwon, Hyuk Sang / Patel, Abhishek / Greenwell, Henry / Hill, Margaret / Katwal, Diksha / Rademacher, Anthony Charles / Mendoza, JuanTwenty 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 platformmatched 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 platformmatched groups were 0.1 ± 0.3 mm and 0.4 ± 0.8 mm, respectively.
