Manufacturing Method of Transparent Dental Alignment Device and Transparent Dental Alignment Device Manufactured by the Method

Abstract

Disclosed is a Transparent Dental Alignment Device and a manufacturing method for the Transparent Dental Alignment Device. The disclosed manufacturing method for the Transparent Dental Alignment Device includes the steps: 3D printing the dental alignment device using a composition for forming transparent dental alignment devices as the raw material (S10); Removing uncured resin and liquid from the dental alignment device obtained in step S10 (S20); Post-curing the dental alignment device obtained in step S20 (S30); Post heat treatment of the dental alignment device obtained in step S30 (S40); Cleaning the dental alignment device obtained in step S40 (S50).

Claims

1. A manufacturing method of a transparent dental alignment device includes the following steps and conditions. Steps: 3D printing the dental alignment device using a composition for forming transparent dental alignment devices as the raw material (S10) Removing uncured resin and liquid from the dental alignment device obtained in step S10 (S20) Post-curing the dental alignment device obtained in step S20 (S30) Post heat treatment of the dental alignment device obtained in step S30 (S40) Cleaning the dental alignment device obtained in step S40 (S50). Conditions: The step (S20) can be performed by spraying compressed air with a pressure of 5-12 bar into the dental alignment device. The step (S30) can be performed at a temperature of 60-90? C. The step (S40) can be performed at a rate of less than or equal to 25? C./min, starting from a temperature of 60-90? C. The step (S50) can include a cleaning solution washing step (S50-1) and a water rinsing step (S50-2). Between the cleaning solution washing step (S50-1) and the water rinsing step (S50-2), there can be a time interval of 5 minutes or more to allow the cleaning solution to dry completely.
