Background: Oral rehabilitation using removable dental prosthesis for patients with maxillofacial defects and missing teeth could pose a challenge while trying to achieve prosthetic treatment goals. It is important therefore to determine how complex the case is before proceeding with treatment. Aim: The aim of the study was to assess the complexity of removable dental prosthesis at a tertiary hospital in Nigeria using the Restorative Index of Treatment Need (RIOTN) System. Materials and Methods: This was a descriptive cross-sectional study of patients who sought for removable prostheses. Data were collated by means of an interviewer-administered question which collated data on biodemographic characteristics of the participant, indication for removable prosthesis, tooth to be replaced with removable prosthesis. Following a clinical examination, the RIOTN System was applied to assess the complexity of the treatment needed. Results: Ninety-eight adult patients with age ranging from 18 years to 90 years with a mean age of 45.17 ± 18.06 years participated in the study. Partial dentures were the most prevalent prostheses provided (91.8%). The most prevalent complexity grade recorded was Grade I (84.7%). There was a statistically significant association between complexity and Kennedy's class of saddle (P < 0.0001) as well as the type of support for the removable prosthesis (P < 0.0001). Conclusion: The pattern of the complexity of treatment using removable dental prostheses was dependent on the type of prosthesis, teeth replaced, support, and saddle.
