Background
The functional correction is an important part in orthodontic treatment, and the functional corrector is utilized to promote the normal growth and development of craniomaxillofacial muscles by regulating the functions of the oral and facial muscles so as to achieve the aim of correcting and treating dental and jaw deformities. Traditional occlusal plates require a clinician to make a model of the patient's teeth, record the occlusal relationship, and then send a mechanic's room to complete the subsequent processing: assembling a frame, bending a snap ring, manufacturing a wax pattern, packing the wax pattern into a box, filling glue, and polishing. The process usually requires 1-2 weeks, which is long for patients who need to wear the medicine immediately; and the appliance has larger volume, strong foreign body sensation after being worn and larger influence on the tooth aesthetic degree.
The thermoplastic film pressing sheet is a common material for dentistry, is commonly used for manufacturing a hot-pressing film tooth socket appliance (a bracket-free invisible appliance) and a transparent retainer, has good retention force, is convenient and quick to manufacture, is low in cost, and can keep good elastic modulus after being formed. And may be combined with an acrylic resin (PM resin): an adhesive may be used in combination with the photocurable resin (e.g., acrylated epoxy, unsaturated polyester, polyurethane, and polythiol/polyene photocurable resins, all commonly used in 3D printing).
It is also a recent trend to combine functional correction with bracket-free invisible appliances. However, due to the manufacturing process of the film-pressing appliance, the functional portion of the shell-type appliance added with the shape of the functional appliance is vacuole-shaped, and then some inherent disadvantages are generated: 1. the strength is insufficient, the deformation is easy, and particularly, the area needing the bite plate cannot bear the pressure during chewing; 2. the tooth socket in the vacuole area is not contacted with the teeth, so that the control of the appliance on key teeth is reduced; 3. the thickness and hardness of the membrane are increased, resulting in reduced elasticity and difficulty in taking off and wearing.
Additive manufacturing methods are becoming increasingly popular in dental applications. Digital models of the tooth forms of patients can be obtained through intraoral optical scanning and model laser scanning, and digital appliance models can be designed on the basis, so that the digital appliances can be manufactured through a 3D printing technology. However, the bite plate manufactured by the pure 3D printing method has some disadvantages: large volume, thick edge, insufficient tooth wrapping degree, insufficient retention force, and simple structure.
