Progress of Tooth Loss by the Concentration of Occlusal Force

Abstract

Assessments of the partially edentulous arch are conducted the grasp of the overviewof clinical case, the predictions of the effect and risk factors of prosthesis and the prognostic factor on the basis of the examination of the dento-occlusal triangula relationship, Eichner classification, receiving factor and pressure factor. However, there are clinical cases that the above-mentioned assessments are not connected with the treatment plan, even if the partially edentulous arches are the same cases. Thus, the balance of occlusal force as the assessment indicator for the partially edentulous arch is useful in addition to the above-mentioned assessments.
