AIM The purpose of this study was to compare the effects of a differently designed functional appliance (the R- appliance) with Fränkel-2. STUDY DESIGN Twenty-seven patients (16 girls and 11 boys) with a mean age of 9.8 (SD 1.6) years were treated with the R-appliance for 15.4 (SD 0.4) months and twentyseven (15 girls and 12 boys) patients with a mean age of 9.1 (SD 1.1) years were treated with a Fränkel-2 appliance for 19 (SD 5.6) months. All patients had Class II division 1 malocclusions… 
Effect of Bionator and Farmand Appliance on the Treatment of Mandibular Deficiency in Prepubertal Stage.
TLDR
Despite the different designs of the appliances, both were successful in the treatment of class II division 1 malocclusion in mandibular-deficient patients.
Treatment effects of R-appliance in vertical growing patients - Case series
TLDR
R-appliance was successful in moving the mandible forward in vertical growth pattern patients without proclination of the lower incisors and the incisor mandibular plane angle decreased and the IMPA significantly decreased.
Effectiveness of the Equiplan in the treatment of Class II, Division 1 Syndrome
TLDR
Positive changes were accomplished with the Equiplan in three space planes in the Class II division 1 malocclusion with mandibular Retrognathism, a development disorder characterized by excessive overjet, deep bite and retrognatic profile.
Dentoskeletal modifications in Class II deep bite malocclusion treatment with anterior bite plane functional appliance
TLDR
This appliance seems to suggest a significant beneficial effect in mandible displacement by reducing the counter clockwise rotation of the mandible, which is further confirmed by the almost absence of modifications of ArGoMe and SNGoMe angles.
Dento-skeletal effects of mixed palatal expansion evaluated by postero-anterior cephalometric analysis.
TLDR
MPE may effectively increase transverse dimensions and correct posterior crossbites in growing patients with a uni- or bilateral posterior crossbite and mild-to-moderate crowding as compared to untreated growing individuals using postero- anterior (PA) cephalometric analysis.
Maxillary "en masse" high-pull traction in Class II division 1 subjects: Which kind of skeletal outcomes does it produce?
TLDR
The high-pull traction on the Stephenson plate produced more dental than skeletal outcomes in growing subjects, despite of the application of orthopaedic forces.
Class II division 1 malocclusions: comparisons between one- and two-step treatment.
TLDR
It can be assumed that both the one- and two-step treatment are effective in correcting Class II malocclusion, with no significant difference of outcome, except for the incidence of incisor trauma, which was significantly lower for the early treatment group.
Skeletal effects in Angle Class II/1 patients treated with the functional regulator type II
TLDR
The functional regulator type II was an effective treatment modality for Angle Class II/1 malocclusion and influenced the skeletal development of these patients in favorable ways and yielded additional insights into sagittal and vertical growth changes not identifiable by strictly cephalometric means.
The Effects of Maxillary Protrusion on Pharyngeal Airway Dimensions
TLDR
It is demonstrated that Tongue Appliance doesn’t affect sagittal airway dimensions but it increases vertical dimensions in the short time.
Orthodontic treatment need for adolescents in the Campania region: the malocclusion impact on self-concept
TLDR
The findings confirm the relationship between psychosocial well-being, self-esteem, and dental malocclusion among adolescents and confirm the role of dental crowding and crossbite in development of global self-concept score abnormalities.

Treatment effects of the R-appliance and twin block in Class II division 1 malocclusion.
TLDR
Both treatment modalities were successful in moving the mandible forward, however, with the R-appliance, this was achieved without retroclination of the lower incisors.
Treatment effects produced by Fränkel appliance in patients with class II, division 1 malocclusion.
TLDR
It was concluded that the main effects of the Fränkel appliance during this time period were mostly dentoalveolar with a smaller but significant skeletal mandibular effect.
R-appliance: a different design in functional therapy in Class II Division I malocclusion.
TLDR
Results of this study showed SNA and IMPA had no significant changes in experimental group in comparison with the control group, and increase of IMPA and reduction of SNA are two prevalent side effects of most functional appliances.

Early functional treatment in Class II division 1 subjects with mandibular retrognathia using Fränkel II appliance. A prospective controlled study.
TLDR
The Fränkel II appliance produced, in CS1-2 subiects, significant effects in teeth position, skeletal modifications and soft tissue changes, although the pubertal growth spurt would occur at least two years later.
Evaluation of long-term effects in patients treated with Fränkel-2 appliance.
TLDR
FR-2 treatment, in conjunction with a period of post-functional fixed appliance therapy designed to perfect the occlusion, can produce a long-lasting improvement of the skeletal Class II malocclusions with little skeletal correction and significant incisor compensation.
Treatment effects of the mandibular anterior repositioning appliance on patients with Class II malocclusion.
TLDR
The results of the study showed that the MARA produced measurable treatment effects on the skeletal and dental elements of the craniofacial complex, which included a considerable distalization of the maxillary molar, a measurable forward movement of the mandibular molar and incisor, a significant increase inMandibular length, and an increase in posterior face height.
Class II treatment effects of the Fränkel appliance.
TLDR
It was concluded that the effects of the FR in the correction of Class II malocclusions are primarily dento-alveolar, with a smaller participation of skeletal changes.
