“…Significant differences of the two-dimensional enlargements in sagittal, transversal, and frontal aspect of the condylography of chewing sequences have been described [9][10][11][12]. There is a reasonable basis to assume a correlation between the transverse extent of chewing movements and some skeletal and dental/occlusal factors, although further research has to be conducted to be able to draw a final conclusion.…”

The aim of this paper is to describe the possibilities of analyzing human mastication. The use of a standardized food model and a standardized protocol using condylographic recordings to create primary data was described elsewhere. Based on the findings of a systematic literature search the current analytic approaches to analyze human mastication showed that a chewing sequence is complex and influenced by many factors. Yet it was not able to establish a valid and robust model to describe human mastication pattern, taken into account known and unknown confounders such as age, sex, number of teeth, and quality of occlusion, either natural or artificial.A newly developed tool is introduced in this paper. The generic data are created by a jaw tracking system and the complexity of the chewing sequence fragmented in single chewing cycles. Planar calculations in all three spatial planes (sagittal, horizontal, and frontal) are used to describe each chewing cycle. Considerable differences in the calculated areas can be detected. Interindividual distinctions could be assessed, but working and non-working side, initial, median, and terminal chewing cycles of a chewing sequence showed considerable intraindividual differences.Comparable parameters, created in such an approach, should have the capability for a better understanding of complex mandibular dynamics during chewing. It can be assumed, that better understanding of human mastication, based on measurable values, will support diagnostic and therapeutic efforts for both, clinicians and researchers.

“…The minimum distance between the condylar surface and the surface of the articular eminence was found to be smaller on closing than on opening [64]. But, huge interindividual differences of jaw movements, recording with electronic devices, make it difficult to come to a final solution [85][86][87][88]. Furthermore, the exact definition and examination technique of the so-called joint loads are not established and further studies need to be done on that particular subject.…”

“…Individual chewing pattern has been demonstrated in many studies [45,[85][86][87][88]. The origin and amount of variation in chewing patterns were identified: number of chewing strokes, mean muscular work, masticatory frequency, opening duration, closing duration, occlusal duration, vertical amplitude, lateral amplitude, and opening and closing velocity.…”

The aim of this paper is to describe the possibilities of analyzing human mastication. The development of a standardized food model is presented. Based on the findings of a systematic literature search an elastic food model was created with the aim of standardizing size and elastic properties. Three different eatable jellied products were chosen, created by a changing of the amount of gelatin (260 Blooms) related to the total mass of the standard jellied food. The different hardness were classified in soft, medium and hard, flavored identically, but stained with different colors: soft-green, medium-yellow, hard-red. A cylindrical form was chosen with a height of 1 cm and a diameter of 2 cm. A standard protocol for analyzing chewing patterns in men was created. The condylographic data off several patients are described in details to demonstrate the possible clinical implementation. The newly developed standard food model (SFM) showed the capability to serve in experimental settings to analyze human mastication, although only a few patients have been examined. In addition, strength and size of the newly developed SFM load the masticatory system in an extent; it should be possible to disclose subclinical symptoms of patients within a short time of examination. The diagnostic procedure of temporo-mandibular disorder (TMD) should be endorsed by this new method. The condylographic data created by a standardized protocol should have the ability to enhance the clinical functional analysis of patients previous to restorative dental procedures
