The effect of anteroposterior inclination of the occlusal plane on biting force

Comparative Evaluation of Maximum Bite Force in Dentulous and Edentulous Individuals with Different Facial Forms

“…In edentulous patient, there are many factors that influence the magnitude of the biting force of an individual such as the anteroposterior inclination of the occlusal plane on biting force [7], effect of altering the vertical dimension of occlusion on biting force [8,9], type of teeth used and occlusion pattern [10].…”

Change in Bite Force and Electromyographic Activity of Masticatory Muscle in Accordance With Change of Occlusal Plane

“…From the level of activation of some muscles, we can estimate that an occlusal plane vertical to the vector of the muscle stimulation will be most effective. Because it is difficult to find the direction of the vector using a morphologic search, the occlusion efficiency value was proposed 33 to understand how much the mastication muscles generate the biting force. That value was used in the present study.…”

“…The calculation of the occlusion efficiency was as follows 33 : occlusion efficiency (EMG/bite-force slope) ϭ [EMG(m) ϩ EMG(t)]/biting force, where EMG(m) is the mean value of the EMG measurements of the bilateral masseter muscles and EMG(t) is the mean value of the EMG measurements of the bilateral anterior temporal muscles. This formula adds the EMG value of the anterior temporal muscle and the EMG value of the masseter muscle and divides the result with the biting force.…”

Structural equation modeling for alteration of occlusal plane inclination

“…Occlusal force is most effective when the occlusal plane harmonizes with muscle orientation and function (Fig. 6 Upper) [1]. Furthermore, occlusal plane inclination should harmonize with the mandibular movement path [2].…”

“…In 1978, Okane et al [1] investigated the influence of occlusal plane inclination for biting force and biting force exertion efficiency. When the occlusal plane was made parallel to Camper's plane, during maximum clenching, biting force was greatest and the biting force exertion efficiency showed the best value.…”
