Abstract
Patient: The patient was a 69-year-old male who first visited with the chief complaint of mastication disorder due to instability of conventional mandibular full dentures. The mandibular ridge was found to be resorbed severely. We fabricated a two-implant-supported overdenture.
Discussion: This case suggested that the implant-supported overdenture with Rocator abutment whose retentive force can be adjusted by replacing the retention disk is helpful for improving the stability of dentures and improving QoL, especially for patients with severe ridge resorption of the mandible causing instability of dentures.
Conclusion: We treated an edentulous patient with severe ridge resorption of the mandible using implant-supported overdenture with a good outcome.
