ABSTRACT:
The present invention provides a unitary, adjustable mouth prop having jaw engaging plates connected by a spring. The plates hold a resilient molding material to comfortably and securely contact a patient's teeth. The plates are further connected by an adjusting mechanism which is used to adjust and maintain a controlled occlusal opening. The adjusting mechanism is made of a screw extending from each plate and an internally threaded sleeve connecting the two screws. The sleeve is threaded to either draw together or separate the screws and their attached jaw engaging plates, thereby closing or opening the occlusal opening. This sleeve and screw adjusting mechanism allows for easy and gradual adjustment of the size of the occlusal opening, without disruption of the dental procedure or discomfort to the patient.
