title: Bone level changes in dental implants with platform-switched design after immediate and delayed placement in the maxilla.
abstract: This study sought to evaluate platform-switched implants for immediate placement. A total of 136 implants were placed in 58 patients using either an immediate or delayed implant protocol. Bone level changes of the implants were measured mesially and distally and statistically analyzed with linear mixed models. No implant was lost. There was no significant difference between immediate and delayed implants in approximal bone level changes during the first year (95% confidence interval: -0.10 to -0.01 for immediate versus -0.14 to -0.07 for delayed implants). Subsequent bone resorption was negligible in both groups.
