Q3. What do the authors think about the influence of surgical methods (one-jaw or two-jaw surgeries, osteotomy design, and so on), the amount of bony change by the surgery, and post surgical orthodontic treatment on the results of the study? Q4. The authors mentioned that the patients underwent plate removal operation at 6 months after the surgery, and they also discussed about the possibility ...

Model surgery is one of the most important steps in the preoperative workup for orthognathic surgery. In cases of complicated two-jaw surgery, manual model surgery requires many laboratory based steps that are time-consuming and may contain potential errors. Recently, a three-dimensional virtual model surgery (3D-VMS) program (3Txer version 2, Orapix, Seoul, Korea) was introduced. The purpose o...

Skeletal changes greater than those observed in untreated adults have been noted beyond 1 year post-surgery in adult patients who had surgical correction of a long face deformity. The stability of skeletal landmarks and dental relationships from 1 to >3 years post-surgery was examined in 28 patients who had undergone surgery of the maxilla only, and in 26 patients who had undergone 2-jaw surger...

The aim of this study was to evaluate the “Physiological Positioning Strategy (PPS)” as a new treatment modality for orthognathic surgery, which could manage the positioning of bone segments after osteotomy. In this study, 20 patients with skeletal mandibular prognathism were treated by surgery with PPS, jaw exercise was performed after one-day maxilla-mandibular fixation, and the process of bo...

PURPOSE Orthognathic surgery has the objective of altering facial balance to achieve esthetic results in patients who have severe disharmony of the jaws. The purpose was to quantify the soft tissue changes after orthognathic surgery, as well as to assess the differences in 3D soft tissue changes in the middle and lower third of the face between the 1- and 2-jaw surgery groups, in mandibular pro...

The first section of this chapter reviews the current practice in corrective jaw surgery, detailing the conventional method for preparing a surgical plan, as well as the surgical technique used to carry out single jaw surgery with maxillary repositioning. A short orientation on surgical planning transfer methods is described, as well as different technical approaches to the problem in question,...

background and aims. previous data have demonstrated that berberine, a barberry plant alkaloid, possesses various therapeutic properties. this study histologically evaluated the clinical efficacy of a berberine-derived topical gel on periodontal inflammation in patients requiring surgery. materials and methods. this randomized clinical trial was performed on 14 patient (11 females, 3 males) pre...

BACKGROUND This study are to identify the symptomatic changes and condylar stability after 2 jaw surgery without preceding treatments for Temporomandibular joints(TMJ) in class III patients with the TMJ symptoms; and to assess therapeutic effect of 2 jaw surgery and the necessity of preceding treatment for alleviation of TMJ symptoms. METHODS 30 prognathic patients with preexisting TMJ sympto...

After 2-jaw surgery, difficulty in breathing through the mouth and the nose is common due to nasal airway obstruction, intraoral bleeding, and sometimes maxillomandibular fixation. A partially withdrawn nasotracheal tube can be used economically with equal efficacy to the nasopharyngeal airway to provide supplemental oxygen after 2-jaw surgery.
