The recovery of the masticatory function in mandibular segmental resection patients is difficult because of the mandibular deviation resulting from the surgical procedure. Denture insertion and registration of the maxillo-mandibular relationship in these patients are difficult because of poor support, retention, and stability in the denture and record base. After mandibular segmental resection removable partial dentures were used in two cases. Konus Telescope Kronen were used as retainers to have rigid connections to the abutment teeth of the lower dentures and record bases. Palatal ramps were formed in the upper dentures to obtain occlusal contact in the centric occlusion. The mandibular movement in tapping and the masticatory movement in chewing boiled fish paste were observed by MKG. In habitual opening and closing movments, there were remakable mandibular deviations in the operated side and unstable positions were noted at the centric occlusion. The test food list for complete denture wearers was used to evaluate masticatory functions. The results of these evaluations showed diminished chewing abilities compared to the complete denture wearers.
