The effect of occlusal design on muscle activity inimplant supported mandibular overdentur

Abstract EN

The effect of two different occlusal schemes on the muscle activity in implant supported mandibular over dentures was evaluated in this study.

The two occlusal schemes were, the medial positioned lingual zed concept of occlusion and the monoplane occlusion concept.

The electromyography activity of masseter and anterior temporalis muscles was recorded for patients rehabilitated with implant supported mandibular over dentures opposed by conventional maxillary complete dentures.

The results revealed slight increase in the muscle activity in patients rehabilitated with dentures constructed following the medial positioned lingual zed concept of occlusion compared to those rehabilitated with dentures constructed following the monoplane concept of occlusion.
