1. A method of cryptographically secured digital dental treatment planning, comprising:
generating, at an intraoral scanning system, a three-dimensional (3D) virtual model of a patient's dental arch based on stitching together a plurality of intraoral scans of the patient's dental arch, wherein the 3D virtual model comprises a 3D surface representing the patient's dentition at a first arrangement;
encrypting, at the intraoral scanning system, the 3D virtual model using a secret cryptographic key to create a cryptographically secured dental record of the patient's dentition;
adding data of the cryptographically secured dental record comprising the 3D virtual model to a blockchain;
receiving, at a treatment planning system, the cryptographically secured dental record of the patient's dentition;
decrypting, at the treatment planning system, the cryptographically secured dental record;
determining, at the treatment planning system, a target arrangement for the patient's dentition;
determining, at the treatment planning system, a digital treatment plan for the patient's dentition, wherein the digital treatment plan comprises a series of intermediate arrangements for a series of aligners to move the patient's dentition from the first arrangement toward the target arrangement;
adding, at the treatment planning system, the digital treatment plan to the cryptographically secured dental record of the patient's dentition; and
sending, from the treatment planning system, the cryptographically secured dental record of the patient's dentition to one or more data stores to store the cryptographically secured dental record of the patient's dentition.
