Description
Technical Field
The invention relates to the technical field of oral medical treatment, in particular to a hot-pressing membrane template for bonding multifunctional accessories and a forming method and application thereof.
Background
In the traditional fixed correction, molar anchorage is kept, and molar inclination in the mesial direction is prevented, and omega curve, backward bending and outward extending bending are usually formed by bending a rear end arch wire; the strength and rigidity of the arch wire are ensured, and the arch wire is prevented from being processed on an excessively thin and soft arch wire; bending various curves with positive axis effect or using various auxiliary devices in the mesiodial of the teeth needing to move.
In recent years, with the development of orthodontic materials and biomechanics, invisible appliances are increasingly popular with orthodontists and patients. The stealthy ware of rescaling of no support groove is through the three-dimensional digital dentition model who obtains the patient, and based on digital dentition model design tooth removes, 3D prints the stealthy ware of rescaling of preparation series tooth removal mould, and the ware is rescued in the stealthy ware of applying the hot pressing membrane material preparation, and the patient wears a series of stealthy ware and reaches the effect of rescaling the dentition. The invisible appliance is worn on the surface of the tooth crown, the surface of the tooth crown is smooth and has a complex structure, and the fixation and tooth moving efficiency of the invisible appliance are generally increased by adhering attachments on the surface of the tooth crown.
The existing fixing appliance bracket bonding template determines the position of bracket bonding through a digital model of a patient dentition, and a 3D printing bonding template or a guide plate is used. Harder printing resin is used as template printing material for accurate bracket positioning. The template is provided with retention protrusions, or the bracket is fixed on the template by adopting a method of bonding silica gel and hydrosol. Harder printing resin is adopted as a template printing material for obtaining accurate bracket positioning, and the template is difficult to take down after the bracket is bonded due to harder material, so that the bracket which is bonded just now sometimes even falls off. Because the material is harder, when the dentition is disorderly arranged, a common positioning channel is difficult to form, and the tooth is difficult to accurately wear. The silica gel is adopted to fix the bracket, which may affect the accuracy of the bracket in place, the hydrosol is used to fix the bracket, and a large amount of water is needed to flush the bonded bracket, which causes discomfort to the patient and may affect the bonding strength.
The existing invisible appliance attachment bonding template designs an attachment on a dental crown through a digital model of a patient dentition, 3D prints a dentition resin model containing the attachment, and forms an attachment template by hot-pressing a hot-pressing film high polymer material. The hot pressing film accessory template is worn on the dentition in the oral cavity after being filled with light curing resin, and the resin is cured and adhered to the dental crown according to the shape of the accessory template and the position on the dental crown by resin adhesive and ultraviolet irradiation. The operation is complicated, the filling resin sometimes generates bubbles due to insufficient filling, or the filling resin is excessive to cause the resin to overflow the template to form unnecessary fins, so that the effect of accessories is influenced, and the invisible tooth socket is not tightly fitted when being worn.
