Frankel’s Appliance Explained | Discussion with Dr. Mike Mew & Prof. John Mew
Dr. Mike Mew and Prof. John Mew discuss Frankel’s Appliance and its impact on orthodontics and facial growth. They review evidence, meta-analyses, and expert interviews, exploring how FR-2 and FR-3 affect craniofacial development and mandibular growth. Ideal for anyone interested in orthodontic science and facial development.
Links & References on Fränkel Function Regulator (FR) Treatment
1. Yang 2014 – “Treatment effectiveness of Fränkel function regulator on the Class III malocclusion: a systematic review and meta-analysis”
Clinical evidence suggests that the FR-3 might restrict mandibular growth but does not stimulate forward movement of the maxilla. Further high-quality studies are necessary to confirm the effectiveness of the FR-3.

2. Perillo 2011 – “Meta-analysis of skeletal mandibular changes during Frankel appliance treatment”
The meta-analysis showed that the FR-2 was associated with enhancement of mandibular body length (0.4 mm/year, 95% confidence interval [CI] 0.182–0.618), total mandibular length (1.069 mm/year, 95% CI 0.683–1.455), and mandibular ramus height (0.654 mm/year, 95% CI 0.244–1.064). A consistent heterogeneity among studies was found for all the considered linear measurements. The FR-2 appliance had a statistically significant effect on mandibular growth.
However, the heterogeneity of the FR-2 effects, the quality of studies, the differences in age, skeletal age, treatment duration, and the inconsistent initial diagnosis seem to overstate the benefits of the FR-2 appliance. An evidence-based approach to the orthodontic outcomes of the FR-2 appliance is needed by selecting and comparing groups of children with the same cephalometric characteristics with and without treatment.
