MAPA: The Three-Dimensional Mini-Implants-Assisted Palatal Appliances and One-Visit Protocol

Abstract The palatal vault is useful for both biomechanical and, especially, anatomic reasons. Nevertheless, the palate does not present a uniform thickness, varying from individual to individual, and great care therefore needs to be taken to analyze the availability of bone to guarantee good primary stability and reliable anchorage. We present here a mini-implants insertion guide designed specifically for palatal application (MAPA). This template is able to ensure not only that mini-implants are placed at the correct depth in the maxillary bone but also that multiple implants are parallel as possible. It is therefore suitable for mini-implants destined for anchorage of removable devices, as well as preformed and tailored appliances used in fixed orthodontics. The MAPA system is very versatile and is used to treat different types of malocclusion (Class III, Class II, narrow maxilla, and asymmetric cases).
