RESUMEN
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.

Twenty-four patients completed this randomized, controlled, blinded clinical trial comparing ridge preservation with a membrane (acellular dermal matrix graft [ADMG]) vs no membrane on buccal overlay graft technique. An intrasocket corticocancellous allograft with a facial overlay xenograft was used for both groups, and an ADMG was used as a membrane with guided bone regeneration in the ADMG group (control group). In the No Membrane group (test group), ADMG was used to cover only the occlusal surface for graft containment, with no membrane on the buccal overlay graft. Final crestal ridge width and vertical ridge height had no significant difference between groups (P > .05). Facial contour was preserved for the ADMG group compared to No Membrane group. Histologic examination showed a high percentage of vital bone for both groups with no significant difference between groups.
