INTRODUCTION In order to obtain an overlay-free assessment of dental structures for resorption and ankylosis diagnostics, conebeam computed tomography (CBCT) is being employed more and more often in orthodontics alongside dental CT. OBJECTIVE The aim of this study was to investigate the quality and accuracy of CBCT in the imaging of dental structures and(More)
OBJECTIVE An analysis of the distribution of stresses at the juvenile and adult cranial base after implementation of a rapid palatal suture expansion was the goal of this study. Of particular interest were stresses occurring near the cranial foramina containing vulnerable structures. MATERIALS AND METHODS The stresses were simulated and analyzed using a(More)
BACKGROUND AND AIM The prediction of soft tissue esthetics is important for achieving an optimal esthetic outcome in orthodontic treatment planning. Applicable procedures have so far been restricted to two-dimensional profile predictions that have not proven to be very reliable. The goal of this investigation was therefore to develop a novel finite(More)
OBJECTIVE The objective of this prospective, comparative study was to evaluate the potential of allowing immediate (within 72 hours) loading of palatal implants used for maximum orthodontic anchorage. This is in contrast to the standard protocol calling for a healing period of 12 weeks. MATERIALS AND METHODS Sixteen patients with a mean age of(More)
INTRODUCTION Demineralization around the bracket is an undesired side effect of orthodontic treatment. The aim of this in-vitro study was to evaluate the efficacy of 5 bonding agents to prevent enamel demineralization. Two quantification methods were used. METHODS Eighty-five extracted teeth were randomly allocated to 5 groups: (1) Transbond Plus SEP and(More)
Eight banded teeth on two human specimens (9 years, male; 19 years, female) were analyzed regarding the fit of the orthodontic bands and periodontal reactions. Five teeth (three molars, two premolars) were evaluated histologically in the horizontal plane and three (one molar, two premolars) in the sagittal plane using the micro-section method according to(More)
BACKGROUND AND AIM The goal of this study was to analyze the validity and prediction accuracy of a newly-developed procedure for three-dimensional soft tissue prediction based on Finite Element Method, and to compare the results with prediction produced using an existing two-dimensional prediction program (Dentofacial Planner Plus). PATIENTS AND METHODS(More)
OBJECTIVE To test the hypothesis that there is no difference in the bond strength with or without contamination with artificial saliva when using two different self-etching primers (Transbond Plus and iBond) in comparison with a conventional acid-etching method (37% phosphoric acid and Transbond XT) for bonding of orthodontic brackets. MATERIALS AND(More)
OBJECTIVE To compare the severity of clinical inflammation parameters and the level of the inflammatory mediator interleukin (IL)-1beta during orthodontic treatment by using brackets and bands. In addition, the effect of a chlorhexidine-containing varnish was investigated. MATERIALS AND METHODS This prospective randomized controlled trial included 40(More)
