Patients having undergone hemi‐mandibulectomy without further reconstruction (to restore the lost mandibular continuity) suffer functional limitations due to the resultant deviation of the segmental mandible. A palatally based guidance prosthesis (or palatal ramp prosthesis) is often indicated and is usually fabricated chairside in self‐cured acrylic resin. Establishing the correct angulation of the slope of the palatal ramp may take several attempts before a satisfactory correction is achieved. This clinical report describes a laboratory technique in which a semi‐adjustable articulator was used for fabricating the palatal ramp prosthesis. The patient's deviated mandibular position was transferred to the articulator by means of a facebow and interocclusal record. The angulation of the palatal ramp was then established on the semi‐adjustable articulator and the prosthesis fabricated in heat‐cured acrylic resin. Reduced chairside time, improved patient comfort levels, and ease in fabrication of the prosthesis on the semi‐adjustable articulator are proposed advantages of the described technique.
