“…The AMEX appliance was designed to reinforce the anchorage of the noncrossbite side teeth by including the mandibular posterior teeth with the aid of the stopper part of the appliance. 25 It is known that light and continuous force produces better physiologic adaptation, greater stability, and less relapse potential than do other forces. 36,37 To deliver light physiologic force, 2 helixes were constructed on the crossbite side, and the appliance initially was expanded 8 mm.…”

“…4 A modified quad-helix appliance has been designed to produce asymmetrical expansion. 25,26 However, its effectiveness has been presented in case reports; it has not been evaluated by evidence-based research. The purpose of this study was to evaluate the dental effects of the asymmetric maxillary expansion (AMEX) appliance in treating true unilateral posterior crossbite.…”

“…W-arches and quad-helix appliances can be modified by changing the arms' length to include more teeth in the anchorage unit [24]. Fixed lingual arches have proven to require less overall treatment time and cost-effectiveness compared with removable appliances [25]. A modified quad-helix appliance has been designed to produce asymmetrical expansion [26].…”

True unilateral posterior crossbite in adults is a challenging malocclusion to treat, especially when we need to correct cross-arch segments with unwanted effects on non-cross segments. Conventional expansion methods are expected to have some shortcomings; the Unilateral dental expander appliance used to restore unilateral cross bite dental arch is an uncommon appliance; for this, a designed new device is needed. This paper aimed to invite a new unilateral dental expander appliance (UDEX) to treat unilateral dental posterior crossbite in adults using available dental material, easy to use and handle, well tolerated by the patient, and biocompatible with oral structure. It could find that in all dental markets and dental clinics-an eighteen-year-old female with bilateral crossbite and upper and lower dental arch crowding. During active orthodontic treatment, a quad-helix expander had broken from one side at soldering between band and wire attachment. The patient did not show up to the clinic for a while due to COVID 19 pandemic lockdown, leading to a true unilateral crossbite at the dental arch's upper left side, especially at the molar premolars area. This unilateral cross bite was treated using a new specially designed expanded appliance as a unilateral posterior cross bite dental maxillary expander. As a result of this study, orthodontic treatment was finished within (15) months, much less than expected. We obtained Class I molar and canine relationships with uncrossed dental arches in both upper arch sides, proper overbite and overjet with well-leveled and aligned teeth as it confirmed by clinical examination and radiographic images (OPG (Orthopantomogram) and cephalometric radiograph (WebCeph analysis digitalized computer program). Conclude from that, the newly designed unilateral dental expander (UDEX) is proven to be useful for treating real unilateral posterior crossbites as single molar or premolar tooth and multiple joint unilateral crossed posterior teeth. Also, it could easily modify it for future unilateral crossed purposes. This appliance was fabricated using readily available dental
