目的:评价三种印模方法的临床效果,常规,闭着嘴,和组织调理剂,全口义齿制造。
方法:60名受试者(无牙颌伴严重再吸收的牙槽脊-AtwoodIII或IV级)访问无锡市口腔医院口腔修复科,中国,2022年1月至2023年6月,被选入本研究。将受试者随机分为三组,每组20人:常规印模组(CI组),闭口印模组(CM组),组织调理剂组(TC组)。义齿修复完成三个月后,义齿质量由临床医生根据边缘延伸进行评估,保留,和稳定性。此外,患者填写了口腔健康影响概况-无牙(OHIP-EDENT)问卷,以提供最终义齿修复结果的主观满意度评价.
结果:义齿质量综合评价结果显示,TC组评分最低,显著低于CM组(P=0.014)和CI组(P<0.001)。CM组的平均得分也显著低于CI组(P=0.004),说明组织调理剂修复是最有效的方法。OHIP-EDENT评分从CI到CM再到TC逐渐降低(P=0.001),表明患者的口腔健康显著改善使用组织调理剂。
结论:组织调理剂是一种合适的动态功能印模方法。它可以显着提高无牙颌患者的疗效并增加其满意度。
OBJECTIVE: To evaluate the clinical effect of three impression methods, conventional, closed-mouth, and tissue conditioner, on complete denture fabrication.
METHODS: 60 subjects (edentulous with severely resorbed alveolar ridges - Atwood classification III or IV) who visited the Prosthodontic Department of Wuxi Stomatology Hospital, China, between January 2022 and June 2023, were selected for this study. The subjects were randomly divided into three groups of 20: a conventional impression group (CI group), a closed-mouth impression group (CM group), and a tissue conditioner group (TC group). Three months after denture restoration was completed, denture quality was assessed by clinicians in terms of marginal extension, retention, and stability. In addition, patients completed the oral health impact profile-edentulous (OHIP-EDENT) questionnaire to provide subjective satisfaction evaluations of the final denture restoration outcomes.
RESULTS: The comprehensive denture quality evaluation results showed that the TC group had the lowest score, which was significantly lower than that of the CM (P= 0.014) and CI (P< 0.001) groups. The average score of the CM group was also significantly lower than that of the CI group (P= 0.004), indicating that tissue conditioner restoration was the most effective method. The OHIP-EDENT scores gradually decreased across the groups from CI to CM to TC (P= 0.001), indicating patients\' oral health was significantly improved using tissue conditioner.
CONCLUSIONS: Tissue conditioner is a suitable dynamic functional impression method. It can significantly improve the effects for edentulous patients and increase their satisfaction.
