Vector of Device Placement and Trajectory of Mandibular Distraction

Stress Distribution in Mandible and Temporomandibular Joint by Mandibular Distraction: A 3-Dimensional Finite-element Analysis

“…Mandibular distraction is less invasive than mandibular surgery, and since it can be performed before the end of the growth period, it also enables psychological stress to be reduced 25) . Moreover, when compared to surgical transfer of the mandible in the anterior direction, the degree of lengthening is greater for mandibular distraction, while the degree of retraction is smaller 8) . However, as far as the indications for mandibular distraction are concerned, it is necessary to ascertain the effects of bone lengthening on the surrounding tissue 6,9) , the direction and design of lengthening screws 21) , and prevalence of infections from lengthening devices.…”

Facial asymmetry revisited: Part II–Conceptualizing the management

“…Augmentation of the alveolar ridge in alveolar hypoplasia can be done using transport distraction osteogenesis. In DO, following age dependent overcorrection is recommended to counteract the poorer growth potential of the genetically recessive (micrognathic) mandible 21 :…”

A new 2-dimensional method for constructing Visualized Treatment Objectives for distraction osteogenesis of the short mandible

“…In the literature, very few articles were found that address the vectors of mandibular distraction (Losken et al, 1995;Grayson et al, 1997;Grayson and Santiago, 1999;Gateno et al, 2000;Rubio-Bueno et al, 2001;Scolozzi et al, 2007). Open bite development during mandibular distraction is encountered by most authors and the origin is considered to be multifactorial.…”

“…However, it might be that incorrect placement of the device and the resulting direction (vector) of separation of the segments is to blame. In the literature, conflicting guidelines are presented without discussion (Grayson et al, 1997;Grayson and Santiago, 1999;Samchukov et al, 1999;Rubio-Bueno et al, 2001).…”
