Clinical evaluation for partially edentulous arch and strategies of prosthodontic treatment for missing teeth

―Benefit of free-end edentulous avoidance―

Abstract

The presence of the last molar in the case of intermediate molar edentulous is considered to stabilize the jaw position by maintaining the interocclusal relation and contribute to the long-term prognosis and stability of the prosthetic device. From the viewpoint of the missing form, it is expected that the pressure factor will be reduced as the occlusal support tooth and the pressure receipt condition will be improved by avoiding the free end edentulous. In this paper, we would like to consider the significance of the residual molars, that is, the intermediate edentulous. Among them, looking back on the selection conditions of the abutment device considering the effect of connecting and fixing the abutment teeth (primary fixation / secondary fixation), and the intraoral changes in the implant overdenture case in which the free end edentulous was modified to an intermediate edentulous. I would like to consider the harmfulness due to the free end edentulous.
