Mandibular fractures are frequently encountered in oral and maxillofacial surgery. Open reduction and internal fixation (ORIF) is one of the treatments of choice (1-3). Maxillomandibular fixation (MMF) is usually performed during surgery (2-5). Recently, an arch bar was reconsidered as a means of providing additional stability to internal fixation in anterior mandibular fractures (1, 5). The ar...

An analysis was made of 78 pathologic specimens in which a right aortic arch was present. In four, the right arch was part of a double aortic arch. In 74 cases the right aortic arch was the only arch. The cases of right aortic arch could be subdivided into two groups as follows: (1) that with a retroesophageal aortic segment (three cases) and (2) that without a retroesophageal segment (71 cases...

three major arteries normally originate from the aortic arch. variations of the aortic arch branches are observed in some cases. rare variation of the aortic arch branches is originated from the retroesophageal right subclavian (rrs) artery as the last branch of the aortic arch. variation of artery is possibly associated with the variation of the recurrent laryngeal nerve. this research provide...

The treatment of Class I malocclusion treatment is to arrange the teeth position in a good arch form. Arch form consists of tooth size and arch dimension (intercanine width, canine depth, intermolar width, molar depth). Several ways are developed to describe arch form. A lot of methods used to describe arch form qualitatively. The objective of this study is to develop qualitative arch form diag...

The aim of this paper is to explore conventional methods of teaching the arch-design studio withideas of sustainability and creativity as agents of change. If this is realised, it means the students of architecture canbe grounded in designing with sustainability and creativity ideas and can be professionals that design and build withideas of creativity and sustainability. So, there are real bui...

Introduction: A study model is a precise three dimensional replica of patient’s dentition and plays an important role in treatment planning. Many digital multi-media applications have become available to the clinician and his or her staff to facilitate standard procedures in practice and management. The aim of this study is to evaluate reliability and validity of dental measurement made on dig...

Total aortic arch replacement remains a complex surgical procedure, best practiced in high-volume aortic centers. The following report details the surgical procedure for total arch replacement with selective antegrade cerebral perfusion (SACP) for distal arch aneurysm. Following moderate hypothermic circulatory arrest and SACP, the distal arch, and then the proximal arch, is reconstructed, foll...

introduction: the objective of this study was to gather information about normal occlusion and arch dimensions in the primary teeth of the children belonging to an iranian population. methods: this descriptive cross-sectional study was performed on 68 children from the city of mashhad in the 3-5 age range. dental arch dimensions, interrelationships of primary canine and second molars, overbite ...

Various surgical techniques have been developed for the repair of an interrupted aortic arch. However, tension and Gothic arch formation at the anastomotic site have remained major problems for these techniques: Excessive tension causes arch stenosis and left main bronchus compression, and Gothic arch configuration is related to cardiovascular complications. To resolve these problems, we adopte...
