The purpose of this study was to analyze the stress distribution patterns within the craniofacial complex during rapid maxillary expansion. Therefore, a finite element model of a young human skull was generated using data from computerized tomographic scans of a dried skull. The model was then strained to a state of maxillary expansion simulating the(More)
Sixty-six patients with carcinomas of the anterior tonsillar pillar and/or soft palate-uvula underwent radiation therapy. Three methods were used: (a) conventional fractionation, (b) a combination of conventional fractionation and radon seed implant, and (c) split course therapy in which two one-week courses were separated by two weeks rest. On time, dose,(More)
AIM The aim of this study was to determine any skeletal morphologic features evident on a pretreatment lateral cephalogram that may be used to predict improvement in the sagittal relationship during functional appliance therapy in Class II patients and compare changes between cases with and without a favorable response to growth modulation.

The direct bonding of a fixed wire retainer often poses clinical difficulties. While there are several possible techniques, the present paper describes a simple method employing a ball clasp (S handle) to assist in the stabilisation of the wire to be attached. The advantages and disadvantages are indicated.
OBJECTIVES To assess the null hypothesis that there is no difference in the rate of dental development and the occurrence of selected developmental anomalies related to shape, number, structure, and position of teeth between subjects with impacted mandibular canines and those with normally erupted canines. MATERIALS AND METHODS Pretreatment records of 42(More)
INTRODUCTION Transverse deficiency of the maxilla is a common clinical problem in orthodontics and dentofacial orthopedics. Transverse maxillary deficiency, isolated or associated with other dentofacial deformities, results in esthetic and functional impairment giving rise to several clinical manifestations such as asymmetrical facial growth, positional and(More)
Research in the field of orthodontics is now focused on the biology of tooth movement. Advanced molecular biology techniques has showed the researchers new avenue towards finding answers to the questions asked for the last few decades. Now it is possible for the researches to explore the lacunae in the field. One such field is, pharmaco-therapeutically or(More)
