Abstract
Partial denture methods have long been applied as typical prosthetics of missing teeth.
In this regard, abutment devices have much clinical potential. However, on the occasion of new abutment device introduction, although clinicians have big expectations, clinical results have been unsatisfactory.
On reason for this may be that applied results have not been analyzed sufficiently thoroughly.
Clinicians follow standard decision-making processes when planning treatment for missing teeth, including choice of abutment.
As a matter of course, the abutment device must be chosen based on correct diagnosis-treatment planning.
This article proposes a strategy focusing on a background of diagnosis for prosthetic of missing teeth and selection rule of abutment device.
