Masks for the treatment of Class III malocclusions
A method that utilizes 3D scans of the patient’s face to 3D print customized facemasks for the treatment of Class III malocclusions. The customized facemasks also feature pressure and temperature sensors, which are linked to both, a game app for mobile devices, in order to promote patient’s compliance and an app for monitoring the therapy by the orthodontist.
Usually, an early intervention in childhood is indicated for the treatment of class III malocclusions. However, currently marketed facemasks, are only available in two sizes. These are often bulky and poorly tolerated by young patients, with reduced comfort, application time and which affect overall treatment effectiveness. Therefore, a method has been developed to manufacture customized facemasks that can be well tolerated by children. On a 3D scan of the patient’s face, the midline bar and the frontal and mental supports are 3D modelled. A 3D printer processes the design information and produces the above components, using a light and biocompatible photopolymer for frontal and mental supports. The supports also contain pressure and temperature sensors used to monitor the patient’s performance during the treatment and its connect wirelessly to a game application for mobile device. The “gamification” experience promotes the child compliance in wearing the facemask for the recommended time, also through friendly competition with other patients within a virtual worldwide community.
