Abstract

Objective: To assess patient satisfaction and peri-implant soft tissue changes of PEEK (BioHPP ® ) bar compared to cobalt chromium (Co-Cr) bar retaining four implants mandibular overdenture. Subjects and methods: Ten completely edentulous participants received four implants and were allocated into two groups. Group I: Co-Cr-bar attachment, Group II: BioHPP ® -bar attachment. Mucosal recession (MR), probing depth (PD), modified plaque index (mPI) and modified bleeding index (mBI) were assessed at the time of overdentures insertion (T0), and after twelve months (T12). Patient satisfaction was also evaluated at (T12). Results: Co-cr bars showed significant increase in all studied peri-soft tissue parameters’ readings. In addition, BioHPP ® bars recorded significant better patient satisfaction scores regarding patient comfort, taste of food, esthetics than Co-Cr bars. Conclusion : Both Co-Cr bar and BioHPP® bar connecting implants supporting mandibular overdenture are considered potential treatment options. BioHPP ® bar presented better results than Co-Cr bar concerning soft tissue changes and patient satisfaction.
与钴铬棒固定下颌种植假牙相比,BioHPP®棒周围的患者满意度和软组织变化:一项随机临床试验
目的:评价PEEK (BioHPP®)棒与钴铬(Co-Cr)棒固定四种植体下颌覆盖义齿的患者满意度和种植周软组织变化。对象和方法:10名完全无牙者接受4颗种植体,分为两组。第一组:Co-Cr-bar连接,第二组:BioHPP®-bar连接。在覆盖义齿插入时(T0)和12个月后(T12)评估粘膜退行(MR)、探深(PD)、改良斑块指数(mPI)和改良出血指数(mBI)。患者满意度也在(T12)进行评估。结果:Co-cr棒显示所有研究的软组织周围参数读数显著增加。此外,与Co-Cr棒相比,BioHPP®棒在患者舒适度、食物味道和美学方面的患者满意度得分显著提高。结论:Co-Cr棒和BioHPP®棒连接种植体支持下颌覆盖义齿是潜在的治疗选择。在软组织改变和患者满意度方面,BioHPP®棒优于Co-Cr棒。
