Özet


OBJECTIVES: Removable partial dentures (RPDs) are commonly used in patients with long edentulous spaces, particularly when implants are contraindicated. This study aimed to evaluate the prevalence of mechanical and biological complications that may affect the survival of RPDs and to investigate their association with different classificationsystems and denture age.

MATERIALS-METHODS: A total of 205 RPDs from 134 patients were examined. The distribution of dentures by jaw, Eicher and Kennedy classifications, denture age and both mechanical and biological complications were recorded. The relationship between complications and denture age, Eichner classification, Kennedy classification, as well as the correlation between denture age and the classification systems, was analyzed using one-way ANOVA and the chi-square test, with significance set at p<0.05.

RESULTS: No association was found between denture age and either classification system. Among the complications, only ulcerations showed a significant difference betweenthe jaws, being more common in mandibular dentures. Mechanical complications were most frequently observed, with the most common being the loss or fracture of artificial

teeth. Of all complication types, only mechanical complications were significantly associated with denture age, occurring more frequently in mandibular dentures aged 10 years or older and maxillary dentures aged 15 years or older. Denture stomatitis was significantly associated with Kennedy Class III, and inflammatory papillary hyperplasia with Kennedy Class II, both observed in mandibular dentures; in the maxilla, epulis fissuratum was more frequent in Eichner groups A3 and C1.

CONCLUSIONS: The frequency of mechanical complications increased with denture age, supporting the need for regular follow-up, especially after 10-15 years. While certain associations were found between complication types and classification systems, their predictive value in assesing complication risk appears limited, emphasizing the importance of individualized evaluation in RPD maintenance.
