The "FAD" (Floating Alveolar Device): a bidirectional distraction system for distraction osteogenesis of the alveolar process.

Purpose: The following study illustrates preoperative and perioperative vector management in alveolar distraction using a new distraction system--the "Floating Alveolar Device" (FAD). The FAD is a bidirectional alveolar distractor that allows augmentation of an atrophic alveolar process in several planes, assures easy intraoperative positioning of the planned vector of distraction, and provides correction of the horizontal position of the transported segment during and after vertical distraction.

Patients And Methods: The FAD is composed entirely of stainless steel and has the following basic components: an upper member, a distraction rod, a lower base plate supporting the vertical force of the distraction rod, a jointed hinge that connects the upper and the lower members, and a tightening rod that provides blocking of the hinge.

Chin augmentation.

The primary goal of facial aesthetic surgery is to restore, enhance, and rejuvenate the aging face to a more youthful appearance, achieving balance and harmony. The mental area must be addressed in order to have a complete synthesis of the face. The concept of augmenting the mental area with implants has evolved so significantly that it now stands by itself as an important procedure.

Remodeling of the temporomandibular joint following mandibular distraction osteogenesis in the transverse dimension.

Transverse mandibular distraction osteogenesis involves moving the osteotomized segments of the mandible in either a varus or valgus direction. This maneuver allows for widening of the bigonial distance or for a lateral shift of an asymmetric mandibular midline. During this process, a significant amount of torque is placed on the mandibular condyles, because they act as the pivot point for the mandibular translation.
