During orthodontic treatment enamel demineralization can occur. Its early detection is the basis for efficient preventive measures to arrest or remineralize lesions. In the present study, the application of a novel blue hemoglobin-based liquid (BlueCheck) was evaluated as proof of concept for detection of on artificially demineralized smooth surfac...
Zusammenfassung
Der Wittenberger Arzt Konrad Victor Schneider (1614–1680) hat als Erster den Nachweis erbracht, dass Schleim nicht im Gehirn gebildet und auch nicht über das Siebbein in die Nasenhöhle sezerniert wird. Er hat erkannt, dass es keine offene anatomische Verbindung zwischen Gehirn und nasalem Luftraum gibt. Schneider hat die sinunasale...
Zusammenfassung
Das Management von Patienten mit einer Molaren-Inzisiven-Hypomineralisation (MIH) gewinnt durch die steigende Prävalenz zunehmend an Bedeutung. Bei der Therapieplanung ist ein enger Austausch zwischen Zahnarzt und Kieferorthopäden von erheblicher Bedeutung, da neben dem Defektausmaß auch die gegebenen dentalen und skelettalen Faktor...

Objective
Rapid maxillary expansion (RME) is an established and frequently used procedure to overcome maxillary constriction. In-depth studies about morphological changes of the alveolar process and its immediate surroundings are missing. Therefore, the aim of the present study was to examine the treatment effects of a dentally anchored, rapid maxi...
Background:
Caries lesion activity is typically assessed by visual-tactile criteria. Regular monitoring is required to detect the transition of lesions and to ensure that the initial assessment was valid. This clinical study aimed to evaluate the agreement of bioluminescence measurements (Calcivis imaging system, Cis) with visual examination to as...
Purpose
Enamel demineralization can occur as a side effect during orthodontic treatment with fixed appliances and should be detected as early as possible. A new approach to assess demineralization is a system consisting of a photosensitive protein that binds to free calcium ions at the enamel surface. A camera is then used to visualize the biolumin...

Die Überwachung des Zahnwechsels sowie das frühzeitige Erkennen und Abgewöh...
Conventional dental-borne rapid maxillary expansion (RME) leads to a widening of the airways, followed by improved nasal breathing. Although combined skeletal-dental appliances are nowadays being inserted increasingly often and provide a force at the center of resistance in the nasomaxillary complex, no study exists so far that shows whether this t...
Permanent retention is currently the method of choice to stabilize orthodontic treatment results. Frequently, permanent retention schemes are adopted to prevent posttreatment changes in the esthetic zone of the anterior teeth. With increasingly prolonged times of intraoral device use, and retention to be provided in the maxilla despite limited spac...

Introduction:
Rapid maxillary expansion (RME) is a common technique to improve the dental and skeletal transverse width in cases of constricted maxillary arches. Although retention after RME has been widely examined, there is still no clear statement about the minimal retention time in postpubertal patients and many practitioners have retention co...
Interactions between the cervical spine and the stomatognathic system have been discussed in literature. The present study was conducted to investigate whether, and to what extent, orthodontically induced mandibular advancement produces changes in cervical spine posture. Furthermore, possible appliance-specific effects should be distinguished.

The success of rapid maxillary expansion is hard to predict in patients from the age of 20. There are as yet no reliable parameters enabling us to define success or failure a priori. The aim of this study was thus to use micro-CT techniques to quantify suture morphology three-dimensionally, and investigate its relation to age.
The morphology of the...

Background
The complex anatomy of the occipitocervical region (OCR) is described in anatomical and radiological journals extensively. Up to now only few data on the radiological morphological variance of this region exist -- this is especially evident for newborn babies, toddlers or schoolchildren. Moreover -- independent of age -- these findings a...
There is a growing market of biomaterials for orthopedic applications. As soon as these materials are surgically introduced
into the constantly remodeling bone of the patient, they start to interact with the local cells: osteoblasts and osteoclasts.
At the first glance, the bone building osteoblasts seem to be the more important cells for osseointe...
352 children radiologically identified with asymmetry in the occipito-cervical region were assessed on a number of myofunctional measures. In all children an orthopedic examination was conducted including a functional test of the upper cervical spine and the iliac joint, the postural test by Matthiass, as well as gait analysis. During a second exam...
Rapid maxillary expansion (RME) is a therapeutic orthodontic option with a long history, and there are many reports in the literature reporting widely divergent results concerning the appliance efficacy and many different treatment protocols. We aimed to evaluate the treatment protocols and clinical experiences with RME via a national inquiry of or...
The aim of stimulating plate therapy in patients with trisomy 21 is to correct orofacial dysfunctions and prevent the establishment of subsequent morphological characteristics such as protrusion of the incisors and pseudoprognathia.

Orofacial regulation therapy for children with Down's syndrome was introduced to Europe in Munich in 1978. Since then, many clinical studies have provided scientific evidence that this therapeutic approach enhances the orofacial function and facial appearance of children with trisomy 21. Only few long-term results have been published to date.
