Loss of teeth can lead to resorption of the residual alveolar ridge, along with a reduction in the patient's neuromuscular function due to decreased proprioception. This can ultimately lead to denture failures. Saving the remaining natural teeth and utilizing oral proprioception for bone preservation and better prosthesis control can prevent such problems. Telescopic overdentures offer the patient several advantages, such as reduced residual ridge resorption, better stability, proprioception, and support. Therefore, the concept of overdentures is truly preventive. This article reports on a case where the patient was prosthodontically rehabilitated with a telescopic overdenture for the mandibular arch and a cast partial denture for the maxillary arch.
