Increased Inflammatory Gene Expression in Masseter Muscle of an Orthognathic Surgery Subject with Obstructive Sleep Apnea
… The latter two conditions may prompt orthognathic correction. Past investigations have shown a genetic association with OSA. Given that masseter muscle influences skeletal malocclusion and is active during OSA, we investigated whether the expression of OSA-associated genes is altered …

Abstract Effect of timing on treatment outcomes and surgical complications of orthognathic surgery in Class II patients
… treated with a combination of orthodontics and orthognathic surgery. The severity of the malocclusion and growth potential play an important role in the treatment decision. Treatment involving orthognathic surgery is usually recommended after active growth is over to minimize relapse. On the …

Effects of orthognathic surgery on quality of life compared with non-surgical controls in an American population
… self-reported quality of life changes following orthognathic surgery result from the surgery itself or from other factors. Objectives: To determine the psychosocial effects of correcting facial skeletal mal-relationships on quality of life, depression, and anxiety in a group of surgically treated …

3D Analysis of Hard Tissue Movement after Orthognathic Surgery in Skeletal Class III Malocclusion with Facial Asymmetry Patients
본 연구는 안면 비대칭을 동반한 골격성 3급 부정교합 환자의 악교정 수술(Le Fort I osteotomy: LF I or bilateral sagittal splint ramus osteotomy: BSSRO) 후 경조직의 3차원적 변화에 대해 분석하여,치료 계획 설정시 수술 후 예후를 고려한 정확한 평가가 이루어 질 수 있도록 알아보고자 하였다. 연구 대상은 2013년 3월부터 2014년 2월까지 아주대학교병원 구강악안면외과에서 동일한 1명의 술자가 시행한 악교정 수술 환자 중 수술 전(T1), 수술 2개월 후(T2), 수술 …

The evaluation of the reproducibility of mock surgery using plaster model and lateral cephalometric radiograph in sagittal split ramus osteotomy
… to obtain a satisfactory esthetic result after orthognathic surgery, it is important not only to conduct accurate diagnosis and surgery planning but also to conduct the surgery as planned. In orthognathic surgical planning, after predicting outcome of surgery through lateral cephalometric …

Volumetric, planar and linear airway comparison after maxillomandibular advancement surgery
… is further classified into phase I and II surgery. When phase I treatment fails, orthognathic surgery is judged to be the subsequent step in treating these patients. Orthognathic surgery is considered phase II treatment and can consist of a maxillomandibular advancement (MMA)1-11. Until …

The Use of Resorabable Plates for the Fixation of Mandubular Fractures
… more than 40 years. In oral and maxillofacial surgery, resorbable materials were first tested in animal studies and later used clinically in humans for fixation in traum and orthognathic surgery. A few publication reports the internal fixation of human mandibular fractures with biodegradable …

ACTN3 R577X GENOTYPES ASSOCIATE WITH CLASS II AND DEEP BITE MALOCCLUSIONS
… and genetic variation in masseter muscle of orthognathic surgery patients to determine genotype associations with malocclusion. To determine the associations between genotypes and malocclusions, clinical information, masseter muscle biopsies, and saliva samples were obtained from 60 subjects. …

Development of a Fully Automated Al System for Skeletal Maturity Assessment Using Cone Beam CT
… such as myofunctional appliances and orthognathic surgery. Clinicians look to biological markers, such as the cervical vertebrae and the spheno-occipital synchondrosis to perform such assessment, and automation of this process would greatly assist clinicians with both accuracy and …

EXPRESSION OF HISTONE DEACETYLASE 4 AND HISTONE ACETYLTRANSFERASE 4 IN HUMAN MASSETER MUSCLE: RELATIONS TO FIBER-TYPE COMPOSITION IN PATIENTS WITH MALOCCLUSIONS
… been made in orthodontics and oral maxillofacial surgery for the diagnosis and treatment of dentofacial deformities. However, compared with bone, the effect of muscles of the craniofacial complex in the development of dentofacial deformities has received little attention. Recently, cellular and …
