This randomized, single-blind controlled study aimed to investigate the QoL and satisfaction of patients wearing complete dentures with lingualized (LO) and bilaterally balanced occlusion (BBO). Participants were stratified based on their prior experience with complete dentures.
The study involved 131 complete denture wearers who were categorized into four groups: G1-first-time prosthesis wearers treated with LO (n = 33); G2-first-time prosthesis wearers treated with BBO (n = 31); G3-participants with prior prosthesis experience treated with LO (n = 34); G4-participants with prior prosthesis experience treated with BBO (n = 33). After wearing the prosthesis for one month, all participants completed the Oral Health Impact Profile (OHIP-14) questionnaire. A statistical analysis was conducted using the χ test, Kruskal-Wallis analysis and Mann-Whitney test, with significance determined at < 0.05.
After dividing the respondents into two groups, a statistically significant difference was observed in the distribution of scores for three questions related to oral pain severity, anxiety, and difficulty relaxing. However, the distribution of scores for all other questions did not show a statistically significant difference between the groups studied ( < 0.05). The total OHIP-14 score was also not statistically different (z = 0.469; = 0.639). However, when respondents were divided into four groups, the median score for first-time denture wearers was 3.9 points higher in respondents who received dentures with BBO compared to those with LO ( < 0.001). Furthermore, the median score for first-time denture wearers who received BBO was higher than for those in the second group who received BBO ( = 0.013).
Patients wearing complete dentures for the first time demonstrated significantly higher satisfaction with the LO scheme compared to the BBO scheme. In contrast, satisfaction levels between occlusal schemes did not significantly differ among patients with prior denture-wearing experience. Novice denture wearers reported heightened sensations of oral discomfort, anxiety, and difficulty relaxing regardless of the occlusal scheme compared to experienced wearers, likely due to the unrealistic expectations that first-time wearers often have about complete dentures.
本随机、单盲对照研究旨在调查佩戴舌侧集中（LO）和双侧平衡咬合（BBO）全口义齿患者的生活质量（QoL）和满意度。参与者根据其既往佩戴全口义齿的经验进行分层。
该研究纳入了131名全口义齿佩戴者，分为四组：G1-接受LO治疗的初次佩戴义齿者（n = 33）；G2-接受BBO治疗的初次佩戴义齿者（n = 31）；G3-有义齿佩戴经验且接受LO治疗的参与者（n = 34）；G4-有义齿佩戴经验且接受BBO治疗的参与者（n = 33）。佩戴义齿一个月后，所有参与者完成口腔健康影响程度量表（OHIP-14）问卷。采用χ检验、Kruskal-Wallis分析和Mann-Whitney检验进行统计分析，显著性水平设定为<0.05。
将受访者分为两组后，在与口腔疼痛严重程度、焦虑和放松困难相关的三个问题的得分分布上观察到统计学显著差异。然而，在研究的组间，所有其他问题的得分分布没有显示出统计学显著差异（<0.05）。OHIP-14总分在统计学上也没有差异（z = 0.469；P = 0.639）。然而，当将受访者分为四组时，接受BBO义齿的初次佩戴义齿者的中位数得分比接受LO义齿者高3.9分（<0.001）。此外，接受BBO的初次佩戴义齿者的中位数得分高于接受BBO的第二组（P = 0.013）。
与BBO方案相比，初次佩戴全口义齿的患者对LO方案表现出显著更高的满意度。相比之下，有义齿佩戴经验的患者在不同咬合方案之间的满意度水平没有显著差异。与有经验的佩戴者相比，无论咬合方案如何，初次佩戴义齿者报告的口腔不适、焦虑和放松困难的感觉更强烈，这可能是由于初次佩戴者对全口义齿往往抱有不切实际的期望。
