The palatal region has been reported to have the best stability for mini-implant placement. However, the biomechanics from this area require ancillary appliances to mobilize teeth anteroposteriorly. In contrast, mini-implants placed in the mandibular symphysis and zygoma (malar bone) provide versatility in the application of force vectors in the vertical and sagittal dimensions. The failure rate of mini-implants in extra-alveolar sites such as the infrazygomatic crest and the mandibular buccal shelf remains high. The mandibular symphysis and zygoma (malar bone) are alternative options with lower failure rates. Longer mini-implants were developed to provide the possibility of inserting more of the screw threads into the bone, thus improving the anchorage to the point where it is similar to that of miniplates, which require two or three miniscrews for placement. It has been shown that miniplates provide skeletal anchorage with the lowest failure rate among the temporary anchorage devices presently available.
