The aim of this in vitro study was to evaluate the stripping achieved on different teeth (incisors, canines, and premolars) by two grades of abrasive strips used for the first and tenth time. Our second aim was to test the efficacy of these strips by calculating the time necessary to perform interproximal reductions of 0.10, 0.20, and 0.30 mm. Four models(More)
OBJECTIVES To investigate and compare the characteristics of commonly used types of traditional and heat-activated initial archwires at different temperatures by plotting their load/deflection graphs and quantifying three parameters describing the discharge plateau phase. MATERIALS AND METHODS Forty-eight archwires of cross-sectional diameters ranging(More)
AIM To describe the perception and sensations that dental alignment and smile determine in a sample of 180 children aged between 8 and 10 years, to assess whether there is a general trend in the classification of smiles, and to understand the influence of background attractiveness and sexual traits on the judgment of smile in the sample of children and 150(More)
OBJECTIVE To investigate the short-term optical, chemical and morphological changes in Invisalign appliances. METHODS One 'as-received' Invisalign aligner, one 'as-received' Invisalign aligner immersed in artificial saliva for 14 days and 10 Invisalign aligners worn by 10 randomly selected patients for 14 days were used. Fourier'transform infra-red(More)
A 35-year-old female patient with dentoalveolar open bite of 4 mm, molar Class I malocclusion, centered midlines, moderate crowding, and labial inclination of the lower incisor was treated with clear aligners to reduce protrusion and close the anterior open bite. The result showed that clear aligners were an effective method with which to correct this(More)
Objective: To evaluate the efficacy of extractive orthopaedic orthodontic treatment in mixed late dentition in two female patients presenting Class III malocclusion and hyperdivergent facial types due to maxillary retrusion. Materials and Methods: The orthopaedic phase, carried out using posteroanterior extraoral traction combined with rapid palatal(More)
THE AIM OF THIS STUDY WAS TO IDENTIFY AND COMPARE ANY DIFFERENCES IN THE POSITION OF THE ANTERIOR LIMIT OF THE DENTITION PROVOKED BY THREE DIFFERENT TYPES OF ORTHODONTIC MECHANICS: traditional edgewise, straightwire and self-ligating. A sample of 54 patients (selected from a group of 289 patients) possessed a range of Little's Irregularity Index values for(More)
