Innovative impaction treatment: lower arch.

Tooth impaction is a common problem in our clinical practice. Mandibular impactions, compared to maxillary impactions, present greater challenges because the surgical risks of damaging adjacent nerves and vessels, the difficult design of a powerful anchorage and higher resistance during forced eruption due to the high bone density in the mandible. This lecture will detail some of the most common types of impaction cases, including mandibular canines, premolars and molars and their recommended course of surgical as well as orthodontic treatment. Buccal shelf screws, combined with 3-D lever arms are proposed as an ideal mechanical design will be introduced.
