Number of the dentate subjects among the elderly is dramatically increasing, as is the elderly proportion in overall population. Such trends indicate more need for prosthodontic appliances in elderly. The aim of this investigation was to determine the distribution of various prosthodontic appliances in older age cohorts, subventioned by the Croatian Institute for Health Insurance. Data on various prosthodontic appliances subventioned by the CIHI and delivered in all Croatian districts in the period 2002–2006 was obtained and statistically analyzed relative to 4 age cohorts of 50 and more years. The oldest age cohort (80+) showed the least appliance deliveries. The most frequently delivered appliance in all age groups were partial removable dentures (382 456 deliveries). Significantly less deliveries in the oldest age cohort compared to other groups (p

The objective of this study was to measure and assess a number of radiomorphometric indices of the mandibular removable denture wearers taking into account age and gender. In a total of 136 dental panoramic radiographs (DPR) the following parameters were evaluated: MI = thickness of the mandibular cortex below the mental foramen, AI = thickness at the antegonion and GI = thickness at gonion ; PMI = MI/distance between the low border of the mandible and the low border of the mental foramen, and MCI = mandibular cortical index, based on the assessment of the 3 categories of cortical appearance due to the resorptive changes. There were 40 male patients (mean age 72.7 ; range 56 to 84 years) and 96 female patients (mean age 69.7 ; range 48 to 86 years). Patients were grouped according to age into three age groups (1 = less than 65 years ; 2 = 65-75 years ; 3 = more than 75 years). The results revealed that MI, PMI, AI and GI showed a general downward trend with age for the both sexes until 75 years of age when the mean values of GI, AI and MI begun to fall down sharply for females compared to males. The difference was significant between age groups and gender for GI and AI. Only two categories (C2 and C3) of MCI have been recognized in our study sample, due to the relatively old age groups of patients with removable dentures. However, significantly higher incidence of C3 existed in the oldest group of females.

The aim of the study was to determine the number and the type of the occlusal contacts (strong, weak) with respect to the type of the prosthodontic appliance ({; ; ; ; u:ed, remouable, combined fixed-remouable) and with respect to the Eichner classification in patients with their appliances being in a good function for a long time. The aim of the study was also to determine the number and the type of the occlusal contacts (strong, weak) with respect to the type of occlusion (canine guided, group function or balanced) and the presence of the RCP-ICP stide. A total of 440 patients with different types of prosthodontic appliances were examined for the antagonistic occlusal contacts using occlusal strips of llflm and 50 flm. The auerage number of occlusal contacts was 10.5 for the upper and 10.46 for the lower posterior teeth, approximately 5 on each side of the tooth arch. The results of the study suggest that the biggest number of occlusal contacts were recorded for the small span fixed appliances (2 on auerage), the greater span fixed and fixed-remouable prosthodontic appliances exhibited 1.6 occlusal contacts, and the remouable complete denture exhibited 1.2 contact per the tooth in the posterior region. The number of the hard occlusal contacts was significantly greater in fixed and {; ; ; ; u:edremouable prosthodontic appliances in comparison with the complete dentures (p < 0.05), white there was no significant difference between the prosthodontic appliances for the weak occlusal contacts (p > 0.05). The ouerall number of the occlusal contacts, as well as the number of the hard occlusal contacts was significantly greater in the Eichner class I cases (p < 0.05) in comparison with the Eichner classes II and III. The number of the weak occlusal contacts showed no significant differences with respect to the Eichner classification (p > 0.05). There was no significant difference in the number of occlusal contacts between the appliances with RCP-ICP stide and where ICP and RCP corresponded (p > 0.05).
