Primary loading of palatal implants for orthodontic anchorage--a pilot animal study.

Summary Objectives This study aimed at evaluating the clinical performance and osseointegration of short orthodontic implants immediately loaded with orthodontic forces. Material and methods The investigation was designed as an experimental animal study. Eight palatal implants of the Ortho-system® were immediately loaded with 100 cN after palatal insertion in 4 female german shepherd dogs. Xylene orange and calcein green were used for polychrome sequential labelling. Histological preparation utilized the cutting and grinding technique. Outcome variables were clinical implant success, histological osseointegration and bone-to-implant contact rates. Results All (8/8) implants were clinically …
