An intraoral scanning system that includes a housing and a sleeve. The housing includes optical components, a head, and a defogging unit that includes a heating unit. The head includes a primary aperture and is configured to be inserted into an oral cavity of a patient. The sleeve includes a secondary optical component arranged at a secondary aperture that is configured to be positioned in alignment with the primary aperture when the sleeve is coupled with the housing. The heating unit is configured to generate heat in response to application of electrical power to the heating unit. When the sleeve is coupled with the housing, the secondary optical component is configured to be arranged such that the generated heat is transferred from the heating unit to the secondary optical component through thermal conduction between the heating unit and secondary optical component.

A wavetrap includes a housing having a base including a base plate. The housing has a wire channel, an inductor pocket and a terminal pocket. The housing has a capacitor pocket that receives a capacitor. The wavetrap includes a defroster wire having a wire end received in the wire channel. The defroster wire extends from the housing for connection to a vehicle defroster circuit. The wavetrap includes an inductor supported by the base plate. The inductor is received in the inductor pocket. The inductor has a coil extending between a first end and a second end. The first end is coupled to the wire end of the defroster wire. The wavetrap includes a ground terminal supported by the base plate. The ground terminal is received in the terminal pocket. The ground terminal is electrically connected to a ground circuit.
