A dental appliance in the form of a bite block for use during dental surgical operations. Integrally in the bite block is formed at least one aperture serving as an evacuation nozzle for a combined saliva and filling debris aspirator. In one of these apertures is inserted a suction nozzle associated with an aspiration device. This bite block thus is the only extra instrument that the dentist needs to place in the oral cavity of the patient in addition to his working tools. |
