Abstract:

Magister Scientiae Dentium - MSc(Dent)<br>The Tip-Edge and edgewise techniques are the main techniques that are mostly used in orthodontics, and are applicable to the treatment of any type of malocclusion from the most simple to the most complex. The edgewise bracket wire combination produces bodily tooth movement simultaneously or separately in all three planes of space and hence permits correction of the most extreme tooth malpositions. On the other hand Tip-Edge offers a differential tooth movement (just like the previously used Begg technique) within an edgewise based bracket system (Park

Abstract:

The domain of medical imaging analysis has burgeoned in recent years due to the availability and affordability of digital radiographic imaging equipment and associated algorithms and, as such, there has been significant activity in the automation of the medical diagnostic process. One such process, cephalometric analysis, is manually intensive and it can take an experienced orthodontist thirty minutes to analyse one radiology image. This thesis describes an approach, based on genetic programming, neural networks and machine learning, to automate this process. A cephalometric analysis involves

Introduction: Class II Division 1 malocclusions are characterized by a retrusive mandible and prominent upper incisors. Despite Class II malocclusions being one of the most frequently treated cases in orthodontists' office, there is no uniform consensus in the orthodontic community on the best treatment modality and biomechanical approach to use in treating patients with Class II malocclusions. Purpose: This paper examines the end-of-treatment outcomes of severe Class II Division I malocclusion patients treated with surgical versus non-surgical approaches.

Abstract:

AIM: To evaluate the accuracy of current semi-automatic and fully automatic 2D lateral cephalometric analysis programs. MATERIALS AND METHODS: 60 lateral cephalometric radiographs were randomly selected and grouped based their skeletal malocclusions to form 3 equal groups of 20 Class I, 20 Class II and 20 Class III. These radiographs were then analyzed via traditional hand-based analysis. The values obtained from this method of analysis were compared to 4 subsequent methods of analysis. These consisted of semi-automatic analysis using Dolphin Imaging software, semi-automatic analysis using Ko

Abstract:

碩士<br>南台科技大學<br>電機工程系<br>96<br>The failures of medical device might cause hazard to patients or operators. So, the software contained in a medical device should be verified and validated to insure the safety and the quality. Software engineering practices, risk analysis and management, and configuration management should be integrated in the study of software verification and validation (SV&V). Those approaches are acceptable by the FDA for the SV&V. In this work, the V-model was introduced in the software development process for the quality management of software development.

碩士<br>國立臺灣大學<br>臨床牙醫學研究所<br>96<br>Purpose The purpose of this retrospective study was to compare post-operative changes and skeletal stability between bilateral saggital split ramus osteotomy (BSSO) and intraoral vertical ramus osteotomy (IVRO) used for mandibular setback. Factors contributing to skeletal instability were also identified. Patients and Methods The study included 48 patients with mandibular prognathism, who underwent mandibular setback surgery at the Department of Oral and Maxillo-facial Surgery, National Taiwan University Hospital (NTUH) from January 2001 to December 2006.
