Materials and Methods: Forty patients were divided into CD and ISP groups. Initially, all patients were treated with a mandibular CD. Then, 23 patients remained with a CD while 17 patients were treated with an ISP after wearing the CD for 3 months. OHRQoL was measured using the OHIP-EDENT questionnaire, and MP was evaluated by sieving. Data were recorded before treatment (T0) and after 3 months wearing the CD and ISP (T1). Results: CD treatment did not affect OHRQoL and PM; however, patients treated with an ISP presented improvement in OHRQoL (P < .001) and MP (P < .001) with a high effect size (ES) (Cohen’s d = 2.49 and 2.47, respectively). For intergroup analysis, ISP treatment presented improvement in OHRQoL and MP compared to CD treatment (P < 0.001) at T1 with a high ES (Cohen’s d = 1.80 and 3.29, respectively). The correlation between MP and OHRQoL was positive only for psychologic discomfort in the CD group at T0 (P = .035), suggesting that poor MP increased psychologic discomfort. Conclusion: Converting a CD into an ISP had a positive impact on OHRQoL and MP with high ES. AID - 1072319
