In case extensive atropy of the alveolar process of the mandible may result in the mental foramen becoming located on or near the crest of the residual ridge. This frequently is the cause of discomfort for the denture wearers. When adjustment of the denture does not alleviate the problem, it may be necessary to transpose the nerve and this is also indicated when the alveolar sulcus is to be deepened in this region. We presented case of severely resorbed mandibular ridge with chief complaint of numbness and discomfort over wearing denture which is treated by supraperiosteal vestibuloplasty with bilateral inferior transpositioning of mental nerve. This management resulted in increased vestibular depth for denture retention and stability, as well as it helped us to avoid numbness and discomfort.
