Aim and objective: This study aimed to evaluate the effect of removable partial dentures (RPDs) on masticatory performance (MP) and oral health-related quality of life (OHRQoL) in shortened dental arch (SDA) patients. Materials and methods: Twenty mandibular SDA patients with four occlusal units, opposing with maxillary complete dentition, that were natural teeth or fixed prosthesis, were recruited and measured MP by using gummy jelly (Glucolumn, GC Co. Ltd., Tokyo, Japan) and Glucosensor GS-II (GC Co. Ltd., Tokyo, Japan) (glucose extraction method). In addition, OHRQoL was assessed by using the oral health impact profile-14 questionnaire, which consists of 14 questions with seven domains. The total score and individual domain scores were calculated and used as parameters of OHRQoL. At 2 weeks after the final adjustment of RPD, MP and OHRQoL were assessed by the same method and questionnaire. These data were compared before and after rehabilitation. The p value of <0.05 was considered statistically significant. Results: A total of 20 SDA patients consisting of 17 (85%) females and 3 (15%) males who met the prescribed criteria (45–68 years, mean; 56 ± 8.23 years) were recruited. Both MP (p < 0.001) and OHRQoL (p < 0.001) were significantly improved after rehabilitation. Conclusion: These results suggested that rehabilitation with RPDs significantly improves objective MP and subjective OHRQoL in patients with SDA.
