BACKGROUND: Reverse headgear (a facial mask) is one of the most frequently used interceptive orthodontic devices in patients with Class III malocclusion. It is a simple device but may present some drawbacks related to pressure on the skin generated by the forehead and chin supports linked to the maxillary intraoral appliance by elastics. This can cause injury to the chin and lips.
METHODS: Patients between 7 and 8 years of age were selected from the Unit of Pediatric Dentistry. Orthopedic therapy with a rapid palatal expander and reverse headgear was prescribed for all subjects. The patients were divided into two groups: those who used a facial mask without a silicone chin cup and those who used a facial mask with a silicone chin cup.
RESULTS: Two-hundred subjects including 90 male patients and 110 female patients were enrolled. The groups that used a facial mask with and without a silicone chin cup included 100 patients each. The percentage of subjects without irritation was significantly greater in the group with a silicone chin cup than in the group without a silicone chin cup.
CONCLUSIONS: The authors propose a simple and effective solution to prevent skin irritation on the chin caused by a facial mask. A chin mask is a custom solution that can prevent injury to the chin during treatment when coupled with facial mask therapy.
