Influence of bone density, screw size and surgical procedure on orthodontic mini-implant placement – part A: temperature development

The aim of this in vitro study was to determine the influence of bone density, orthodontic mini-implant (OMI) size, and the surgical procedure on temperature increase during implant site osteotomy and placement. OMIs of different sizes (2.0 ×7, 2.3×7, 2.0×11, and 2.3×11mm) were placed in artificial bone blocks of different densities (D1–D4). Optionally, the drilling and insertion angle was 90° or 60° to the bone surface. A total of 160 OMIs were inserted, and predrilling was performed in 80 cases.
