Abstract

OBJECTIVES: To describe the tissue reactions at the bone-titanium interface of orthodontic miniplates in humans. MATERIALS AND METHODS: Forty-two samples, consisting of tissue fragments attached or not to miniplates or their fixation screws, were collected from 24 orthodontic patients treated with miniplate anchorage, at the time of removal of their miniplates. The samples were embedded in methylmethacrylate and cut into undecalcified sections which were submitted to microradiographic analysis. The sections were also stained and examined under ordinary light. RESULTS: Three types of reactions were observed both on the histological sections and on the microradiographs. 1. The majority of the ..
