Influence of the Configuration of the Lower Posterior Pontic to the Amount of Absorption of the Remained Ridge

Abstract

The purpose of this study was to clarify the influence which was exerted on the absorbed edentate alveolar ridge volume by a pontic base form. We observed totally 189 bridges which had four different pontic base forms-Ridge lap type pontic, Saddle type pontic, Flat back pontic, and Sanitary pontic.
It clarified that a pontic base form influenced the absorbed dentate alveolar ridge volume in the process of years.
It suggested that some pontic base form were able to keep off surplus absorption on dentate alveolar ridge volume.
