AI Technical Summary
Technical Problem
The mechanical strength of the cavity in existing invisible orthodontic appliances is insufficient, resulting in poor stability and high production and transportation costs.
Method used
The repositioning jaw element designed for the dental model is a split structure, including a fixing part and a main body. The main body is left in the accommodating cavity after being formed by hot pressing through a detachable connection. It combines intraoral special model resin and ordinary 3D printing photosensitive resin to enhance mechanical strength and reduce cost.
Benefits of technology
This improved the mechanical strength of the accessory cavity, reduced production and transportation costs, and ensured demolding stability and therapeutic effect.

Abstract
This invention discloses a dental model used as a mold for thermoforming shell-shaped orthodontic appliances. The model includes a dental model body, with repositioning occlusal elements extending towards the opposing jaw on both sides of the posterior tooth region. Each repositioning occlusal element comprises a separate fixing part made of a first material and a main body made of a second material, detachably connected to the fixing part. The fixing part is fixedly connected to one side surface of the dental model body, and a first connecting part is provided on the side of the fixing part facing the main body. The main body has a second connecting part that matches the first connecting part and is detachably mounted along the buccal-lingual direction. To achieve the purpose of this invention, a method for manufacturing a shell-shaped dental appliance is also disclosed.
