Effect of Balanced Occlusion Verses Lineal occlusion on Maximum Biting Force and Electromyographic Activity

Ten completely edentulous male patients participated in this study. All patients received two implants in the canion region. For each patient two complete dentures were constructed. The artificial teeth of one denture was arranged according to full bilateral balanced occlusion, while in the other denture the teeth were arranged according to lineal occlusion concept. The maximum biting force and electromyographic activity were measured after one month from insertion of each denture. The result of the study found that there are no statistical significant differences between the two occlusal concepts.The study concluded that the lineal occlusion did not affect the value of the maximum biting force and electromyographic activity when compared to the bilateral balanced occlusion.
