Dental Lathe Technique for Mouth-Opening Devices

ABSTRACT: The technique presents a simple yet efficient method for fabricating a mouth opening device designed to improve mouth opening functionality. The technique utilises a replicated metal rod, commonly employed for securing a polishing buff in a dental lathe. The fabrication procedure involves an impression with putty consistency of addition silicone impression material. The resultant sectioned putty template is securely fastened with an elastic band. The mouth-opening device can be made either by adding cold cure acrylic resin into the impression template or by producing a wax pattern, which is later processed with heat cure polymethylmethacrylate acrylic resins. The technique proves to be effortlessly simple and quick and readily adaptable in prosthodontic lab environments, distinguishing itself from alternative methods outlined in the literature.
