“…All studies were cost-minimisation analyses comparing two different appliances to correct a malocclusion. Out of the four studies, one concerned treatment of unilateral posterior crossbite 39 , one study was on anchorage loss 40 , one study on large overjet reduction 41 , and one study on anterior crossbite treatment 42 . All four studies came from Sweden and all studies were RCTs.…”

Summary Objectives The objectives of this study were to assess the three-dimensional (3D) treatment changes (palatal surface area and volume) of forced unilateral posterior crossbite correction using either quad-helix or removable expansion plate appliances in the mixed dentition, and to compare the treatment changes with the three-dimensional changes occurring in age-matched untreated unilateral posterior crossbite patients as well as in subjects with normal occlusion and with no or mild orthodontic treatment need. Trial design Six-arm parallel group multicentre randomized controlled trial. Materials and methods One-hundred and thirty-five patients with unilateral posterior crossbite with functional shift were recruited. The patients were randomized by an independent person not involved in the trial. The randomization used blocks of 25, and the patients were randomized into the following five groups: quad-helix treatments in specialist orthodontic clinics (QHS), quad-helix treatments in general dentistry (QHG), removable expansion plate treatments in specialist orthodontic clinics (EPS), removable expansion plate treatments in general dentistry (EPG), and untreated crossbite (UC). Twenty-five patients with normal occlusion who served as normal controls were also included in the trial. Blinding of the outcome assessor and data analyst was accomplished. Data on all children were evaluated on an intention-to-treat basis, regarding 3D palatal surface area, palatal projection area, and palatal shell volume; two-dimensional linear measurements were registered at the same time. Results After treatment, the surface and projection area and shell volume increased in the four treatment groups (QHS, QHG, EPS, and EPG). QHS increased significantly more than EPG for the surface and projection area. The QHS and EPS had significantly higher mean difference for shell volume. Limitations The trial considers a short-term evaluation. Conclusion After treatment, there were no significant differences between the four treatment groups and the normal group, which implies that the surface and projection area together with the shell volume for the four treatment groups and the normal group were equivalent. Trial registration The trial was registered with https://www.researchweb.org/is/sverige, registration number: 220751.

“…Die Effektivität der Minischrauben bei der statischen Verankerung erhielt auch durch eine weitere randomisierte klinische Studie Unterstützung. Dabei wurden Miniscrews mit Blockverankerungen verglichen, bei denen die oberen zweiten Prämolaren und Molaren in Fällen mit extrahierten ersten Prämolaren verbunden worden waren [29]. Hier wurden die eingesetzten Minischrauben ebenfalls als weniger schmerzhaft empfunden als die Extraktion der Prämolaren.…”

ZusammenfassungDer vorliegende Beitrag hat zum Ziel, das Konzept der evidenzbasierten Medizin für die Kieferorthopädie vorzustellen. Dazu werden Geschichte und Philosophie der evidenzbasierten Medizin ebenso diskutiert, wie ihre Implementierung in die tägliche kieferorthopädische Praxis. Der Einfluss der evidenzbasierten Medizin wird dann am Beispiel der Frühbehandlung von Dysgnathien der Klassen III und II, der kieferorthopädischen Bewegung von Zähnen und der skelettalen Verankerung demonstriert. Damit eröffnet sich eine moderne Perspektive auf die bewährtesten Behandlungsverfahren in diesen klinischen Bereichen.

“…Because it is one article in a series, one has to understand that we did not only look at the anchorage capacity but also cost-effectiveness and experience of pain and discomfort. [12][13][14] In this context, it becomes clear that we compared two different treatment concepts: miniscrews and NiTi coil springs versus molar block and active tiebacks.…”
