Relevance of a standard food model in combination with electronic jaw movement recording on human mastication pattern analysis

Abstract

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

Model identification of stomatognathic muscle system activity during mastication

“…Mastication occurs as a result of the force-movement field, and is carried out via a complex interaction between muscle systems, teeth, lips, cheeks, the palate, salivary glands and the temporomandibular joints (4–7). Correct mastication should proceed on both sides of the dental arch openings, since one-sided mastication is the source of an uneven load of the temporomandibular joints (8–10). An important element of mastication which determines the appropriate mechanical grinding of food are the teeth, located in the maxilla and the mandible (11–14).…”
