BACKGROUND: Temporomandibular joint (TMJ) ankylosis is a situation in which the mandibular condyle is fused to the glenoid fossa by bone or fibrous tissue. The management of TMJ ankylosis has a complicated chore, and it is challenging for the maxillofacial surgeon because of technical hitches and high rate of reankylosis. Costochondral graft (CCG) is a common treatment modality for TMJ ankylosis. One of disadvantages of CCG is unpredictability of growth pattern and risk of overgrowth...

Aglossia is a rare congenital abnormality, often associated with micrognathia and limb defects. Situs inversus totalis is also a rare congenital abnormality, defined as a mirror-image reversal of all the asymmetric organs of the thorax and abdomen. The concurrence of these two abnormalities has only been reported in eight similar cases in the literature. Although micrognathia and malocclusion were observed in all of these cases, few treatments were performed for the patients' dentofacial deformities. This report describes the case of a 7-year-old boy suffering from micrognathia, aglossia, and situs inversus totalis simultaneously, and the treatment for his micrognathia by mandibular symphyseal midline distraction osteogenesis, guided by virtual surgical planning and a three-dimensional printed surgical template...

AIM: The Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) is a valid tool aiming to evaluate the self-reported influence of dental aesthetics on quality of life. This questionnaire was developed in English for young adults, and later translated and validated with an Italian population. A new version of the questionnaire was recently introduced to be used in adolescents (11-17 years- old), but it had not been translated in Italian yet. Hence, the purpose of this study was to translate, cross-culturally adapt and validate the PIDAQ for adolescents, for its use among Italian subjects...

OBJECTIVE: Class-1 malocclusion commonly presents with crowding and poses an aesthetic concern to patients. An orthodontist may encounter a variety of dental problems and must handle them strategically to establish adequate occlusal relationships. Hence, this study was conducted to evaluate the occlusal characteristics of patients who have undergone non-extraction or all first premolars extraction treatment for class I malocclusion using the peer assessment rating (PAR) index. METHODS: The pre-treatment and post treatment dental casts of 94 subjects with class-I malocclusion were retrospectively screened...

CONTEXT: Many authors have conducted studies that determine horizontal condylar guidance (HCG) using various methods, articulator systems, and recording materials. However, there is a dearth of literature on variability existing in HCG in individuals with different skeletal relationships. This study is an attempt to verify whether such a difference exists or not. AIMS: The aim of this study is to determine and correlate the HCG in individuals with Angle's Class I, Class II, and Class III malocclusion using radiographic and clinical methods...

REVIEW
Andrew Young
Idiopathic condylar resorption (ICR) is a condition with no known cause, which manifests as progressive malocclusion, esthetic changes, and often pain. Cone-beam computed tomography and magnetic resonance imaging are the most valuable imaging methods for diagnosis and tracking, compared to the less complete and more distorted images provided by panoramic radiographs, and the higher radiation of (99m)technetium-methylene diphosphonate. ICR has findings that overlap with osteoarthritis, inflammatory arthritis, physiologic resorption/remodeling, congenital disorders affecting the mandible, requiring thorough image analysis, physical examination, and history-taking...

Jong Woo Choi, James P Bradley
"Surgery-First" for patients with malocclusion and skeletal disharmony is a new process of employing bony corrective surgery (first) without removal of dental compensations followed by orthodontic finishing (second). This process breaks with the time-tested principles of traditional orthognathic surgery. Not unexpectedly, there is slow adoption of this new process, particularly in the West. Ten frequently asked questions regarding Surgery First are asked and answered in this report in an attempt to provide an increased level of comfort for Plastic and Maxillofacial Surgeons in instituting this process in their practice...

INTRODUCTION: Alveolar bone grafting not only stabilizes the alveolar arch, but also provides positive aesthetic outcomes. However, there have been no reports about the inclinations of the incisor and canine or the change in occlusion after alveolar bone grafting. Therefore, the purpose of this study is to analyze the effects of alveolar bone grafting on tooth angles and changes in occlusion in patients with a unilateral alveolar cleft, using three-dimensional computed tomography. METHODS: The authors retrospectively studied alveolar bone grafts performed in Konkuk University Medical Center between January 2008 and January 2013...
