Abstract

Background/purpose

Implant-supported fixed partial dentures (IFPDs) are a treatment option for partially edentulous dentition with missing posterior-most molars despite the concept of a shortened dental arch (SDA). This study aimed to evaluate the effect of IFPD treatment on oral health-related quality of life (OHRQoL) in patients with unilateral SDA missing two adjacent molars and to compare the effects of single- and two-unit IFPDs.

Materials and methods

Forty patients with unilateral SDA missing two adjacent molars (Kennedy Class II) participated in this study; 11 patients received one implant placement in the first molar and were treated with a single-unit IFPD (single-unit group), and 29 received two implant placements and were treated with a two-unit IFPD (two-unit group). The Oral Health Impact Profile (OHIP) questionnaire for OHRQoL assessment and the gummy jelly test for objective masticatory performance were administered before and after IFPD treatment. The Wilcoxon signed-rank test for all patients and Mann–Whitney U test were performed for pre- and post-treatment comparisons and between-group comparisons, respectively.

Results

The OHIP summary score and gummy jelly glucose concentration in all patients showed significant improvements after treatment (all P < 0.05). No significant differences were observed between the single- and two-unit groups for any of the items. Using the minimal important difference in the OHIP summary score, 63.6 % and 58.6 % of patients in the single- and two-unit groups, respectively, showed improvement by 6 points or more.

Conclusion

IFPD treatment for patients with SDA missing two adjacent molars may provide clinically meaningful improvements in OHRQoL.

种植体支持固定局部义齿治疗对单侧牙弓缩短患者口腔健康相关生活质量的影响
背景/目的尽管有缩短牙弓(SDA)的概念,但种植体支持的固定局部义齿(IFPD)是缺失最后磨牙的部分无牙颌患者的一种治疗选择。本研究旨在评估缺失两颗相邻磨牙的单侧 SDA 患者的 IFPD 治疗对口腔健康相关生活质量(OHRQoL)的影响,并比较单基托和双基托 IFPD 的效果。材料和方法40名单侧SDA缺失两颗相邻磨牙(肯尼迪II类)的患者参与了这项研究;11名患者在第一磨牙接受了一次种植体植入,并接受了单单位IFPD治疗(单单位组);29名患者接受了两次种植体植入,并接受了双单位IFPD治疗(双单位组)。在IFPD治疗前后,分别进行了口腔健康影响档案(OHIP)问卷调查以评估患者的口腔健康质量生活水平(OHRQoL),以及软糖测试以评估患者的客观咀嚼能力。所有患者的治疗前后比较和组间比较分别采用 Wilcoxon 符号秩检验和 Mann-Whitney U 检验。单单位组和双单位组之间在任何项目上均未见明显差异。以OHIP总分的最小重要差异为标准,单单位组和双单位组中分别有63.6%和58.6%的患者改善了6分或更多。

期刊介绍: he Journal of Dental Sciences (JDS), published quarterly, is the official and open access publication of the Association for Dental Sciences of the Republic of China (ADS-ROC). The precedent journal of the JDS is the Chinese Dental Journal (CDJ) which had already been covered by MEDLINE in 1988. As the CDJ continued to prove its importance in the region, the ADS-ROC decided to move to the international community by publishing an English journal. Hence, the birth of the JDS in 2006. The JDS is indexed in the SCI Expanded since 2008. It is also indexed in Scopus, and EMCare, ScienceDirect, SIIC Data Bases. The topics covered by the JDS include all fields of basic and clinical dentistry. Some manuscripts focusing on the study of certain endemic diseases such as dental caries and periodontal diseases in particular regions of any country as well as oral pre-cancers, oral cancers, and oral submucous fibrosis related to betel nut chewing habit are also considered for publication. Besides, the JDS also publishes articles about the efficacy of a new treatment modality on oral verrucous hyperplasia or early oral squamous cell carcinoma.
