Impression Making in Severe Trismus a Novel Technique

Asif Ahmed*

Impression making in a restricted mouth opening poses a technical challenge for Prosthodontist to provide any sort of prosthesis in such patients. Limited oral opening can be caused by head and neck radiation, surgically treated head and neck tumors, facial burns, reconstructive lip surgeries and also in various genetic disorders. In this article a novel technique to obtain a dental impression with the help of wooden tongue blades of post operated and radiated head and neck cancer patients; with trismus where in some mouth opening was less than 1 cm. In this technique we used wooden tongue blades as an impression tray. If impression for both quadrant of same arch is required then we used two tongue blades in a criss-cross manner and joined them with elastics and for single quadrant we used single blade only. This impression technique causes less trauma to already tightened mucosa due to use of wooden blades rather than metallic trays and more over none of our conventional trays will be usable in mouth openings less than 1 cm.
