Examiner differences in the assessment of different malocclusions.

Background: In the current discussion about ensuring treatment quality and reducing costs in the health sector, indication systems with which to determine the need for a treatment and the success of therapy are increasingly being used in orthodontics. These indication systems require the objective evaluation of malocclusions. Our objective was to determine the examiner reliability in the assessment of various malocclusions.

Comparison of craniofacial morphology in patients with unilateral cleft lip, alveolus and palate with and without secondary osteoplasty.

Problem: What kind of skeletal differences do exist between juvenile patients with unilateral cleft lip, alveolus and palate treated with or without secondary osteoplasty, and between cleft patients and non-cleft patients?

Patients And Methods: Thirty-nine patients with unilateral cleft lip, alveolus and palate at a mean age of 15.8 years who were surgically treated with (n = 18) and without (n 21) secondary osteoplasty were compared with a control group of non-cleft patients (mean age 15.1 years).

Presurgical nasoalveolar molding in patients with unilateral clefts of lip, alveolus and palate. Case study and review of the literature.

Introduction: The case of a newborn female patient with unilateral cleft lip, alveolus and palate is presented with a markedly sunken nasal wing at the cleft side. This finding may lead to a very unsatisfactory aesthetic result after primary cheiloplasty and nasoplasty.

Patient And Method: Five months prior to surgery, the patient was treated with a palatal plate and additionally with a nasoalveolar conformer for 4 months thereof.

Prenatal diagnostics of cleft deformities and its significance for parent and infant care.

Introduction: This study aimed to demonstrate clefts of the secondary palate in embryos found to have cleft lip in order to evaluate the validity of prenatal ultrasound examination and, thus, to assess the significance of this diagnostic method for coordination and care of parents and infant.

Patients And Methods: Over a period of 2.5 years, 7 fetuses with cleft deformities were examined sonographically during the 20th and 25th gestational week.

The influence of craniofacial growth in a case of transverse facial cleft.

This report presents the case of a female patient bearing a right-side transverse facial cleft. She has received interdisciplinary treatment since birth. At regular intervals, dental casts were made, and profile and full-face photographs, lateral and postero-anterior cephalograms were taken during the course of orthodontic treatment and maxillofacial surgery.

Influence of examiner differences on KIG-classification when assessing malocclusions.

Objective: Indication systems such as the German KIG system (Kieferorthopädische Indikationsgruppen = Orthodontic Indication Groups) presuppose the objective assessment of underlying malocclusions. In this survey, we aimed to investigate the degree of agreement among the findings of several examiners in the assessment of different malocclusions and their classification according to the KIG system.

Subjects And Methods: Calibrated examiners assessed in the clinical evaluation and on plaster models orthodontic malocclusions in 180 adults (aged 20-49, 64 male, 116 female) from the population-based Study of Health in Pomerania (SHIP).

Do bivariate and multivariate cephalometric analyses lead to different results concerning the skeletal cause of postnormal occlusion?

In most cephalometric studies on the craniofacial pattern of untreated Class-ll-malocclusion subjects mean values were bivariately compared with the mean values of subjects with normal occlusion or Class I malocclusion, or with standard values. A multivariate approach, which does not merely compare two variables at a time but which analyses several skeletal variables at once, is lacking. The objective of the present study was in a first step to bivariately compare the sagittal and vertical skeletal pattern of Norwegian untreated postnormal occlusion patients with Class I children and in a second step to compare the results of the bivariate analysis with the results of a multivariate analysis on the same subjects.

Complete cleft lip and palate without bone grafting and its effect on craniofacial morphology in three planes.

The aim of the study was to analyze the morphology of the viscerocranium in patients with unilatertal or bilateral cleft lip and palate (CLP) who had undergone no surgical intervention of the alveolous meaning that no bone grafting was conducted. In this cross-sectional study 47 patients with complete unilateral (UCLP) or bilateral clefts (BCLP) were examined, and compared to a group of 42 patients without facial clefts. Each group was subdivided into two age groups (ca.

Association of malocclusion and functional occlusion with temporomandibular disorders (TMD) in adults: a systematic review of population-based studies.

The aim of this systematic review of population-based studies was to establish whether or not associations exist between different types of malocclusions, as well as factors of functional occlusion (eg, occlusal interferences, nonworking-side occlusal contacts) and temporomandibular disorders (TMD) in adults 20 years or older. Defined criteria were employed in the search of MEDLINE and EMBASE databases, as well as in a manual search. Finally, using inclusion criteria (eg, random sampling from residents' registration office files or census lists, adequate response rates), out of 22 preselected studies, four relevant population-based studies on this subject were found.
