BACKGROUND Palatal canines are upper permanent canine (eye) teeth that have become displaced in the roof of the mouth. They are a frequently occurring anomaly, present in 2% to 3% of the population. Management of this problem is both time consuming and expensive and involves surgical exposure (uncovering) followed by fixed braces for 2 to 3 years to bring the canine into alignment within the de...

Objective: The aim of this case report was to evaluate the results of deep overbite correction by the segmented arch technique. Methods: The first stage of the treatment was performed with this technique to intrude incisors and canines. A maxillary transpalatal bar and a mandibular lingual arch using 0.051-in archwire were employed associated to a facial bow, anchored primarily with occipital p...

Nasal alveolar molding is used effectively to reshape the nasal cartilage and mold the maxillary arch before cleft lip repair and primary rhinoplasty. It provides aesthetic and functional benefits of nasal tip and alar symmetry and improved dental arch form. At The Craniofacial Center at the University of Illinois at Chicago, the authors have developed a modification of a nasal alveolar molding...

OBJECTIVE The main goal of this study was to optimize unilateral molar rotation correction by modifying a trans-palatal arch (TPA) design using the finite element method. DESIGN Three-dimensional analysis of different TPA designs was carried out using the finite element method. SETTING Department of Orthodontics, Tehran University of Medical Sciences, Iran. MATERIAL AND METHODS For this i...

This case report presents the interceptive orthodontic treatment of a boy, aged 8 years 4 months with a Class I malocclusion with severe transverse maxillary deficiency and complete maxillary crossbite and correction using Haas expansion and fixed appliance. The treatment goals were to correct the posterior crossbite and anterior crossbite and restore the normality of the dentition and occlusio...

Rapid palatal expansion is an orthodontic procedure widely used to correct the maxillary arch. However, its outcome is significantly influenced by factors that show a high degree of variability amongst patients. The traditional treatment methodology is based on an intuitive and heuristic treatment approach because the forces applied in the three dimensions are indeterminate. To enable optimal a...

INTRODUCTION The availability of new, reliable, objective, and 3-dimensional techniques to assess the effects of rapid maxillary expansion on the morphology of the maxillary dental arch, nasal cavity dimensions, and nasal airway resistance led to the development of this research. METHODS Thirty-eight subjects participated in this study (mean age, 13 years). Data were collected before expansio...

OBJECTIVES To evaluate orofacial and occlusion findings associated with obstructive sleep apnea (OSA) in a group of Saudi children. METHODS The sample consisted of 30 OSA patients, and 30 age and gender matched, healthy control. The following facial and occlusal features were evaluated: frontal view, facial profile, mandibular angle, tongue size, dental midline to facial midline, upper to low...
