“…The breakage rate, which resulted in extra visits reported in this study, was seemingly much greater than that which was reported by Ross et al 8 Seventeen FFRD springs had been placed. Although they noted 10 incidents, eight incidents were lost split crimps.…”

Objective: To investigate patients' experiences with the Forsus Fatigue Resistant Device (FFRD). Methods: This was a survey focused on patient's comprehensive experience with FFRD, both initially and after several months of wear, including the patient's overall impression of the appliance. The survey was administered to 70 patients wearing FFRD in both university and private practice settings. Results: A high percentage (81.5%) reported a neutral to favorable experience with FFRD; 89.8% reported growing accustomed to the appliance within 4 weeks. The majority of those who had previously worn rubber bands found FFRD to be ''easier.'' Cheek irritation was the most serious side effect (about 50%). Cheek irritation and other negative effects generally decreased over time. Conclusions: The FFRD is relatively well accepted by patients. Most patients experience some discomfort and functional limitations; however, the effect generally diminishes with time, and patients adapt to the appliance. Practitioners should be especially vigilant about problems with cheek irritation. (Angle Orthod. 2013;83:437-446.)

“…Durability of an appliance is another important consideration when evaluating an orthodontic device and certainly plays a major role in a patient's experience. No quantification of FFRD failures could be found in the literature, except a case report 8 indicating two breakage incidents.…”

“…The device allows patient to open and move their jaw more freely. 7,8 The Forsus Nitinol Flat Spring (FNFS) is an alternative fixed functional appliance described by Vogt in 2001. 9 It has a Nitinol flat wire instead of the coil which is more esthetically acceptable.…”

ABSTRACT:The advent of technology, increased public awareness and patient demands has evolved our speciality to develop with a variety of new and modified appliances. This paper describes various hybrid appliances which can be applied in different clinical situations according to the need of the patient. Selection of the components and their assemblies, resulting in appliance designs that uniquely match the needs of individual patients. Various appliances like fixed functional, esthetic mandibular advancement devices, hybrid hyrax, hybrid orthodontic treatment system, hybrid aligner therapy and biobloc therapy have been described in this paper.

“…Unitek, force levels are similar to Class II elastics, as are the treatment effects, except that Class II correction is typically seen quicker as the Forsus is fixed and cooperation is not an issue as it is with Class II elastics. 115 There have been case reports of the fatigue resistant module breakage 116 however, other studies document the good resiliency of the Niti springs. 117 An updated EZ module has also been released to help reduce breakage, and recent 3M Unitek literature states that the Forsus appliance has been compression cycled tested over 5 million times without breakage or force fatigue.…”

To evaluate the correction obtained from the Forsus Fatigue Resistant (FRD) device and orthodontic appliances compared to an untreated control group. Methods: Twenty four patients were treated with the Forsus FRD and fixed orthodontic appliances and were compared to twenty two untreated control patients who were matched in age, sex and craniofacial morphology. Lateral Cephalograms were taken before treatment (T1) and after Forsus FRD and removal of orthodontic appliances (T2). Results: Statistically significant differences were found for 12 of the 29 variables measured. Significant differences were found at Co-Gn minus Co-Apt., Wits, Is-OLp, Ii-OLp, overjet, Mi-OLp, Molar relationship, Overbite, Mic-ML, SNA, ANB, and Ii-ML between the treated and control groups. Linear measurements in the net position of the maxilla and mandible showed changes that included a reduction in maxillary forward growth and a stimulation of mandibular forward growth; however, these changes were not statistically significant. Net overjet correction was 4.7mm. 1.9mm (40%) of the correction was skeletal and 2.8mm (60%) was dental. Overjet correction was obtained by decreased maxillary growth (25%), increased mandibular growth (15%), retraction of the upper incisor (32%), and proclination of the lower incisor (28%). Conclusions: The Forsus FRD is successful in treating Class II malocclusions; however, there is a significant proportion of the correction which is dental in nature.
