A self-customizable orthodontic retainer comprising a body formed of a semi-crystalline propylene ethylene copolymer. The semi-crystalline propylene ethylene copolymer is a metallocene catalyzed copolymer having a crystallinity from about 2% to about 65% and a melt flow rate (MFR) of from about 2 g / 10 min to about 50 g / 10 min. The flow rate of the material allows the material to flow around the teeth and gums and into spaces between the teeth. After heating the retainer to a temperature in the range of about 60° C. to about 100° C., the body is a moldable material which crystalizes in the mouth at a temperature below 60° C. to conform the retainer to a contour of the mouth, gums, teeth and spaces between the teeth.

This application relates to a method for locating anchor points of orthodontic retainer wires, belonging to the field of orthodontics. The method includes: reading tooth data of adjacent tooth pairs for which wire structures need to be placed, and calculating global reference features; analyzing the global reference features to obtain the labial contact points of adjacent tooth pairs; constructing an orthogonal coordinate system; determining the saddle points where the wire crosses adjacent tooth pairs based on the orthogonal coordinate system, and calculating the first and second characteristic anchor points of the adjacent tooth pairs; setting a cross-sectional point set, and calculating the first vertex, bottom point, and second vertex of a U-shaped path based on the labial contact points of the canines and the cross-sectional point set to construct a U-shaped path; and constructing a three-dimensional coordinate point set for the wire anchor points. This application solves the problem of low anchor point positioning accuracy and efficiency during orthodontic retainer fabrication due to reliance on manual operation by technicians and the lack of standardized parameters.
