Long-term use of ill-fitting dentures may cause irregular movements of the mandible. In such cases, satisfactory outcomes both in terms of function and esthetics could be achieved by accurate registration of mandibular movement and centric relation when fabricating new dentures. In this case, treatment dentures with flat occlusal tables were used to register centric relation and mandibular movements of a patient with erratic mandibular movements.

For patients with unstable mandibular movements and centric relation of the mandible due to long-term use of ill-fitting dentures, the successful fabrication of new dentures is challenging. Before fabrication new dentures, registration of centric relation is the critical point in such cases. In this case, treatment dentures with a flat occlusal table were used to stabilize mandibular movements and to register centric relation. In order to reflect the patient's jaw relation and vertical dimension obtained through the treatment dentures to the final denture, the treatment dentures were digitally duplicated, and impressions and jaw relations were obtained using the duplicated therapeutic dentures. The clinical results were satisfactory on the aspect of aesthetic and masticatory functioned.
