Abstract
The influence of risk factors during the course of tooth loss widely varies in stages ranging from the initial loss to extensive edentulous dental arch. Therefore it is necessary to consider the weight of risk factors when the design of prostheses is determined. On the occasion to investigate what kind of factors are related to the course of tooth loss when faced with individual cases, a total evaluation involving all risk factors and pliable consideration is required. When the hypotheses are verified, however, it would be appropriate to focus on individual problems. The author has performed analyses of factors for the course of tooth loss and their trends. This paper demonstrates some examples of clinical data analyses of risk profiles on a partially edentulous dental arch.
