Abstract

The present disclosure relates to an intraoral scanning system comprising a tip housing configured to be at least partially inserted into a patient's mouth. The tip housing comprises a scanning window, an infrared light source configured to emit infrared light via the scanning window towards the mouth, a first interface unit configured to receive electrical power from a power supply of the intraoral scanning system. The first interface unit is configured to be connected to a first heating conduction path and a secondary conduction path, and wherein the first interface unit is configured to control an electrical heat power level in the first heating conduction path, and wherein the first heating conduction path is configured to transfer heat generated based on the electrical heat power to the scanning window, and wherein the first interface unit is configured to supply electrical power to the infrared light source via the secondary conduction path, wherein the first heating conduction path and the secondary conduction path are at least partially parallel within the tip housing.
