Introduction: Complete edentulous patients are an important part of prosthodontics department referrals. After a while of prosthetic use, complications such as loosening, tissue irritation, and inefficiency in chewing or change the appearance, cause the need of reline. The purpose of present study is evaluation of complete prosthesis relining needs in patients referring to removable prosthodontics department of Tabriz dentistry faculty in 2014. Materials & Methods: This retrospective study was conducted on 96 patients that referred to removable prosthetic department in dental faculty of Tabriz by questionnaire and clinical examination. Data were analyzed in SPSS21 software. In this study, P value less than 0.05 was considered statistically significant.

Results: 61.5 % of patients were men and mostly were in 51-60 years old group. 83.3% had U-shaped ridge and 16.7% had V-shaped ridge. 5.2% of patients only in upper denture and 11.5% of them only in lower denture were required to reline. Also 8.3% of patients in both upper and lower denture were needed reline.75% didn't need to denture reline. Needs to reline were more in U-shaped ridge. Conclusions: Finally, the results of statistical analysis show that there was a significant relationship between need of reline and the residual ridge but there was not a significant relationship between need of reline and gender and also the time of the prosthesis is going to delivery.
