Abstract

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
