OBJECTIVES This study sought to evaluate the accuracy and errors of linear measurements of mesiodistal dimensions of Kennedy Class III edentulous space using cone beam computed tomography (CBCT) in comparison with clinical measurements. MATERIALS AND METHODS Nineteen Kennedy Class III dental arches were evaluated. An impression was made of each dental arch and poured with dental stone. The di...

Introduction: Since the emergence of normal occlusion concept, selecting an appropriate treatment plan with or without tooth extraction has been a controversial subject. Nowadays, both methods can be successfully used for treatment of patients. However, some clinicians still believe that non-extraction orthodontic treatments have fewer complications. The purpose of this study was to evaluate de...

AIM Ectopic eruption (EE) of a first permanent molar occurs during mixed dentition. However, treatment of first permanent mandibular molar EE has been seldom reported. CASE REPORT The cases of an 8-year-old girl and a 7-year-old boy are described, whose EE first permanent mandibular molars were correctly positioned after treatment with a dental appliance comprising a lingual arch, sectional a...

Cubic splines were fitted to the maxillary dental arches of 27 children with permanent dentitions, all having Class I molar, cuspid, and buccal segment relationships. A set ofdata points was chosen to represent arch form, and of these points, five were used as knots of the spline. Error of the fit of the curve was evaluated through the analysis of normals to the curve computed from those points...

BACKGROUND The aim of this retrospective study was to identify which dental and/or cephalometric variables were predictors of long-term maxillary dental arch stability in patients treated with a transpalatal arch (TPA) during the mixed dentition phase followed by full fixed appliances in the permanent dentition. METHODS Thirty-six patients, treated with TPA followed up by full fixed appliance...

The purpose of this study was to compare the dentoalveolar changes produced when using two different intraoperative surgical procedures for maxillary distraction osteogenesis. Eight patients were assigned into two groups according to the surgical procedure: down-fracture (DF, n = 6) vs non-down-fracture (NDF, n = 2). Lateral cephalograms and 3-D models before and after maxillary distraction wer...
