Patient: The patient was a 54-year-old man who complained of tooth hyper-mobility and difficulty in chewing. The mobility of the remaining teeth ranged from M1 to M3 due to severe alveolar bone resorption, and the hyper-mobility induced masticatory disturbance. All of the remaining teeth that were diagnosed as having a poor-prognosis were extracted, and five implant bodies were placed in the maxilla and four implant bodies were placed in the mandible. Implant-supported full-arch dentures were then inserted. The patient was satisfied with the function and esthetics even 3 years and 7 months after treatment.

Discussion: Establishing stable oral function without early re-treatment due to remaining teeth troubles contributed to the patient’s satisfaction.

Conclusion: A patient complaining of masticatory disturbance due to teeth hyper-mobility was successfully treated with implant-supported fixed dentures after extracting poor-prognosis teeth.
