Mandibular ridge extension with bilateral inferior transposition of mental nerve.

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.

Saliva and its importance in complete denture prosthodontics.

Saliva is a complex fluid composed of secretions from salivary glands and gingival crevicular fluid. The oral cavity is a moist environment; a film of fluid called saliva constantly coats its inner surface and occupies its space between the lining oral mucosa and teeth, whose important role is maintaining the well being of the mouth. Saliva plays a critical role in the maintenance of oral and dental health. Saliva is most valuable oral fluid that is taken for granted. Knowledge of the salivary system and saliva is essential for evaluating prosthodontic problems and for educating patients in what to expect in this phase of denture use.
