Having knowledge about the prevalence of partial tooth loss, provides us with a better understanding of social hygiene. On the other hand, having access to such an information, students can be led properly to treat more prevalent cases. The goal of this retrospective study is to investigate the frequency of partial prosthesis classifications, among patients, referred to Shiraz dental faculty. Sexuality, tooth loss classification and its reason and the presence of additional space were studied about all patients (371 females, 205 males) from (97-98) to the end of (99-2000). The results showed that females were more than males (64.4%), the lower jaw was treated more than the upper jaw (67.9%), dental caries were the most important reason for extraction (55.5%), class I among females (28.79%) and class II mod I among males (29.73%) had the most frequency, meaning that the most cases were free end, so more attention should be paid for the education of free end partial prosthesis, however, preventive steps should be taken to retain abutment teeth.
