title: [Molar distalization by using vertically installed mini-screws].
abstract: Mini-screws can be used for orthodontic anchorage in distalizing maxillary and mandibular molars. With them, practitioners can avoid the undesirable reciprocal movement that so often occurs when teeth are used as anchorage units. In this article, we propose a method of vertical insertion of mini-screws that places them in positions that will not interfere with movement of tooth roots. This allows orthodontists to use mass movements of groups of teeth or even of entire arches, thus reducing the need for extractions, simplifying treatment procedures, and enlarging the range of therapeutic possibilities. We evaluate the indications for this vertical placement in different anatomic situations. We suggest different sites for mini-screw placement and illustrate them with many clinical cases.
