The sand-blasted and acid-etched surface-treated mini-implant (C-implant, C-Implant Co, Seoul, South Korea) is designed to endure heavy and dynamic loads and offers high stability during orthodontic treatment, however the implications of its removal are still unknown. The purpose of a study, conducted at the Department of Orthodontics at the Catholic University of Korea, was to evaluate the removal torque values (RTVs) of early-loaded mini-implants. Results showed that all mini-implants remained intact, lead researcher, Professor Seong-Hun Kim, placed the study in context.
