“…The best improvement of the ANB, SNA and SNB angles was in the Kajiyama study (+7·83°, +4·16°, −3·66°). The biggest increase of maxillary length (+4·4 mm) was in Falck and Zimmermann‐Menzel's study using FR‐III, while with RME+FM the greatest increase was reached in Vaughn's study (+4·29 mm). The highest control of mandibular length was in the Yagci and Uysal study with RME+FM (−6·4 mm).…”

“…Regarding vertical changes 6 of 21 studies showed a counterclockwise rotation of the mandible or stability of patient divergence . The greatest counterclockwise rotation was in Falck's study with a reduction of the gonial angle of −7·17° and of −5·15° for the mandibular plane angle. On the other hand, 15 studies reported a significant increase in mandibular divergence.…”

“…Four papers did not find any change in incisors inclination after treatment with CC, MHG or FM . At the end of the functional treatment, six studies found a retroclination or a stable position of upper incisors while eleven showed a proclination (); three found a proclination or a stable position of lower incisors while nine showed a retroclination (Tables and ).…”

“…The age range of the treated group was between 5·6 ± 1·0 years to 12·5 ± 0·7 years while the control group ranged from 4·8 ± 1·4 years to 11·5 ± 1·1 years . The treatment time variation was from 5·2 months to 60 months although it was not reported in one paper . The full observational time was often similar to the treatment time because only two studies reported follow‐up data .…”

“…Furthermore, three studies analysed the methodological error and 11 studies had an adequate statistical analysis. Interestingly, only three studies did not have a sufficient external validity due to the distributions of the confounding factors. Two RCTs of seven achieved the maximum score in both internal validity domains.…”

To summarise the skeletal, dental and soft tissue effects of orthopaedic treatment on growing skeletal class III patients compared with a concurrent untreated similar control group and to evaluate whether the design of the primary studies may affect the results. A literature search was performed up to the end of February 2016. No restrictions were applied concerning language and appliances. Once the quality score was assessed, a meta-analysis was performed for the appliances used in more than three studies. A moderator analysis for study design was performed. The level of evidence was evaluated by means of the Grades of Recommendation, Assessment, Development and Evaluation (GRADE) tool. The search resulted in 21 papers. The quality of most of the studies was medium. Each study reported skeletal sagittal improvement and overjet correction. Fourteen studies reported a significant increase in lower facial height. Follow-up data showed slight relapses in about 15% of patients. Meta-analyses were performed for the facemask and chin cup. The two appliances were efficient for correcting the sagittal discrepancy, increasing the divergence. In the analysis for study design, the retrospective studies showed a more efficient appliance than RCTs for 6 of 13 variables. The level of evidence was between very low and moderate. There is very low to low evidence that orthopaedic treatment is effective in the correction of Class III skeletal discrepancies and moderate evidence for the correction of the overjet. A common side effect is mandibular clockwise rotation in older subjects.

ZusammenfassungDieser Artikel gibt einen kleinen Überblick über den von Rolf Fränkel entwickelten Funktionsregler. Das von ihm beschriebene Behandlungskonzept der orofazialen Orthopädie ist auch heute noch fester Bestandteil im Repertoire vieler Kieferorthopäden weltweit.Von den ursprünglichen 4 Grundtypen finden noch die Typen FR-1 und FR-2 Anwendung bei der Therapie einer Unterkieferrücklage. Der Typ FR-3 kommt als Frühbehandlungsgerät bei einem Missverhältnis im Wachstum beider Kiefer, d. h. bei einer Unterentwicklung des Oberkiefers und/oder Überentwicklung des Unterkiefers zum Einsatz.In diesem Artikel wird der aktuelle Stand der Weiterentwicklungen der verschiedenen Typen des Funktionsreglers erläutert und die zwischenzeitlich stattgefundenen Modifikationen dargestellt. Es wird das klinische Management aufgezeigt. Vorbereitende Maßnahmen, wie z. B. die Abformung der Kiefer und des Vestibulums oder die Anfertigung des Konstruktionsbiss werden erläutert und es wird hierbei auf mögliche Fehlerquellen hingewiesen.Da insbesondere der Erfolg der Therapie auch von der labortechnischen Herstellung abhängt, widmet sich dieser Artikel ebenfalls der Umsetzung der Vorgaben von Rolf Fränkel bei der Fabrikation der Funktionsregler Typen FR-2 und FR-3.

Cephalometric Changes in the Treatment of Class III Using the Fränkel Appliance*

Abstract: According to these study results, FR-3 treatment has an obvious effect on maxillary development, and affects the shape and, to a certain degree, the position of the mandible.
