BACKGROUND It has been hypothesized that prematurity and adjunctive neonatal care is 'a priori' a risk for disturbances of palatal and orofacial development which increases the need for later orthodontic or orthognathic treatment. As results on late consequences of prematurity are consistently contradictory, the necessity exists for a fundamental analysis of existing methodologies, confounding ...

Paramedian insertion of orthodontic mini-implants is increasingly used to anchor molar distalizers. The aim of this review was to systematically examine the available measurements of vertical palatal bone height (VBH). PUBMED, MEDLINE and the Cochrane Controlled Trials Register were searched using specific search terms. Hand searches of bibliographies of articles were also performed to identify...

Background: In children with Down syndrome (DS) the retarded growth potential cause a number of different clinical signs. Morphological deviations and an underdeveloped midface together with hypotonia contribute to increased prevalence of occlusal anomalies. Since the early 1980 ́s orofacial neuro-motor habilitation with palatal plates therapy have been used in Sweden. Aim: to investigate if use...

BACKGROUND Ceramic veneer fracture has occurred mainly at the incisal edge of the veneer because of greater stress. This study compares and evaluates the fracture resistance ceramic veneers with three different incisal preparations. MATERIALS & METHODS 15 human permanent maxillary central incisor extracted were selected which were divided into three groups of 5 each having a different Incial ...

This study analyzed the effect of perennial allergic rhinitis on dental and facial skeletal characteristics. Twenty-five allergic children who were apparent mouth breathers, their 25 siblings who did not have the disease and were apparent nose breathers, and 14 nasal breathing control subjects were examined medically, dentally, and cephalometrically. Compared with their siblings, the allergic s...

This article evaluates intertalker variance of oral area, logarithm of the oral area, tongue height, and formant frequencies as a function of vowel category. The data consist of coronal magnetic resonance imaging (MRI) sequences and acoustic recordings of 5 talkers, each producing 11 different vowels. Tongue height (left, right, and midsagittal), palate height, and oral area were measured in 3 ...

background: implant placement plays a vital role in oral rehabilitation following loss of the incisors. thus, having knowledge of anatomical variations of adjacent neurovascular structures especially the nasopalatine canal (npc) is essential. due to the lack of basic information in iran about the morphology of this canal and the probability of its variety in different populations, this study wa...

While there are many claims that abnormal breathing patterns alter facial growth, there are limited controlled data to confirm this. We evaluated forty-five North American Caucasians of both sexes, ranging in age from 6 to 12 years. Thirty chronically allergic mouth-breathing subjects were selected from a pediatric allergy practice, and fifteen nonallergic nose breathers were selected from a ge...
