SYSTEMS AND METHODS FOR FABRICATING DENTAL APPLIANCES OR SHELLS

摘要

Systems and methods are disclosed for cutting and trimming dental molds and oral appliances by receiving a digital model of teeth, determining a cutting loop path and applying a drape wall to the cutting loop to generate a simplified tooth base in a dental mold having an inner arch curve and an outer arch curve. The oral appliance may be formed on the dental mold and a cutter may be applied using a sweeping motion across the inner and outer arch curves.

主权项

1. A method of forming an oral appliance, comprising:
receiving a digital model of a patient's dentition; calculating a rule-based cutting loop path on the model for determining a path for trimming a mold replicating the patient's dentition; applying a drape wall from the cutting loop on the model to reduce a complexity of the model; determining a position of a cutting instrument relative to the mold for trimming the mold; generating a computer numerical control code based on the drape wall and position of the cutting instrument; and fabricating the mold based on the generated computer numerical control code
