Biomechanical evaluation of a T-shaped miniplate fixation of a modified sagittal split ramus osteotomy with buccal step, a new technique for mandibular orthognathic surgery

Computational geometry assessment for morphometric analysis of the mandible

“…Manual repositioning according to a predefined protocol should be avoided, since this would make this fundamental part of the process as a whole user-dependent. In order to overcome the possible differences in positioning and to make all mandible geometries comparable regardless of the image acquisition technique and segmentation, for this Inc., Malans, Switzerland) and has been used in many different experiments (Bredbenner & Haug 2000;Doty et al 2004;Asprino et al 2006;Schupp et al 2007;Aymach et al 2011;Hakim et al 2014;Steiner et al 2015). Another replica mandible model is offered by Sawbone (Sawbone Inc., Malmø, Sweden).…”

“…In maxillofacial surgery, mandible replicas are used to study the impact of positioning of dental implants , various operation techniques for osteosynthesis placement on fractures or osteotomies (Bredbenner & Haug 2000;Asprino et al 2006;Aymach et al 2011;Steiner et al 2012;Hakim et al 2014;Steiner et al 2015), and bone reconstruction after tumor removal (Bredbenner & Haug 2000;Doty et al 2004;Asprino et al 2006;Schupp et al 2007). Two commercially available models are currently available and advertised for use in biomechanical laboratory settings.…”

“…Aymach14 and Kawamura15 found this technique optimizes the resistance and stability of the fixation when compared with a standard bilateral sagittal split osteotomy (BSSO) fixed with a standard mini-plate.

Comparison of the Stability of Mandibular Sagittal Osteotomy Fixation between Two Types of Titanium Miniplates: A Biomechanical Study in Sheep Mandibles

“…lower risk of inferior alveolar nerve injury and provides minimum condylar sag. 9,10 Condylar position is a major concern of the surgeons by the fact that there is no guarantee that the mandible condyle will be repositioned in the same way as it was at the preoperative period. Condylar sag can induce malocclusion, temporomandibular joint derangements, and condylar remodeling and resorption.…”
