Intraoral appliances with proximity and contact sensing

A system, the system comprising:

• a dental appliance shaped to receive a patient's teeth;
• a sensor module mounted to the dental appliance, wherein the sensor module comprises one or more sensors including a pressure and/or force sensor configured to generate sensor data comprising force and/or pressure data, wherein the sensor module comprises a wireless communications circuitry for transmitting the sensor data to an appliance case configured to receive the dental appliance;
• one or more processors configured to determine a breathing rate based on the sensor data, wherein the one or more processors are further configured to determine a presence of a sleep disorder for the patient based on the determined breathing rate being outside an expected range for a period of time when the patient is wearing the dental appliance;
• and
• the appliance case configured to receive the dental appliance, the appliance case comprising:
• a first antenna configured to wirelessly receive the sensor data from the sensor module when the dental appliance including the sensor module is within the appliance case;
• a data store configured to store the sensor data;
• and
• a second antenna configured to transmit the stored data to an external computing device when the external computing device is within communication range of the second antenna;
• and
• a transmission circuitry configured to receive data from the first antenna and to transmit data from the second antenna.
