Quad Helix

The Quad Helix can be constructed as a fixed or a removable appliance using .036 wire. It is used to widen the arch form with the aid of helices bent at the four corners of the appliance and lingual wires extending anteriorly. All of our Quad appliances are bent from straight wire allowing us to contour the vault accordingly while maintaining the integrity of the wire compared to pre-bent. Indications include all cross bites that need expansion, mild expansion in mixed dentition cases, Class III cases that need expansion, Class II cases, and cleft palate patients. A tongue crib and facemask hooks can be incorporated into the design.

Treatment & Care

There are two ways to activate the quad helix before placing it in the mouth. Ricketts et al. (1979) originally suggested that operators activate the appliance with three-pronged pliers to incorporate expansion and molar-rotating force. Another method proposed by Kholoki (1995) employs an arch form chosen from a pentamorphic chart that serves as a pattern for regulating the quad helix.

This appliance should be cleaned every day with toothpaste and a soft toothbrush, morning and night. Encourage the patient to give sufficient time to clean thoroughly around the appliance, gums, teeth, and bands to maintain proper hygiene and prevent inflammation. 3 minutes is recommended.
