■用植入物替代缺失的牙齿是一种可靠且预期的治疗方法。尽管有许多研究证实了长期成功率,存在一系列潜在的生物和美学并发症。
■本研究的主要目的是评估手术干预后患者的反应,特别强调异种胶原基质(XCM)的利用,无论是否使用固定在愈合基台上的支架,在角化牙龈粘膜增强的情况下。主要目的是评估和比较这两种手术方法产生的临床结果。特别关注包括术后并发症在内的关键参数,患者舒适度,以及实现成功的角化组织增强的总体功效。
■选择60例患者进行本研究。患者分为三组:A,B,和一个对照组,每组由20名参与者组成。我们在实验组A中使用XCM,实验B组XCM覆盖手术支架,对照组为游离牙龈移植物(FGG)。手术后,患者需要完成手术后并发症的视觉模拟评分(VAS)问卷,以及第1、3和7天的生活质量(QOL)问卷。
与对照组相比,实验组A和B的患者表现出明显改善的预后。在第1、3和7天进行的评估显示疼痛程度降低,出血,和两个实验组的肿胀,实验组B表现出最少的不适感。XCM的合并,不管有没有支架,与镇痛药消耗的减少有关,强调其对术后舒适度的有利影响,尽管实验组B有口臭例外。
■使用有或没有支架的XCM进行角化组织扩张,术后结果与肿胀减轻相关,出血,和基于QOL调查的疼痛。本研究为XCM和支架的临床应用提供了数据支持。
UNASSIGNED: The substitution of missing teeth with implants is a dependable and anticipated therapeutic approach. Despite numerous studies affirming long-term success rates, there exists a spectrum of potential biological and aesthetic complications.
UNASSIGNED: The primary objective of this study was to assess patient responses subsequent to surgical interventions, with a specific emphasis on the utilization of xenogenic collagen matrix (XCM), both with and without the application of a stent secured over healing abutments, in the context of keratinized gingival mucosa augmentation. The principal aim was to evaluate and draw comparisons between the clinical outcomes resulting from these two procedural approaches, with a particular focus on critical parameters encompassing post-operative complications, patient comfort, and the overall efficacy in achieving successful keratinized tissue augmentation.
UNASSIGNED: Sixty patients were selected for this study. The patients were divided into three groups: A, B, and a control group, with each group comprising 20 participants. We used XCM in experimental group A, XCM covered with surgical stent in experimental group B, and free gingival graft (FGG) in the control group. After the surgical procedure, patients were required to complete a visual analogue scale (VAS) questionnaire for post-operative complications, and a quality of life (QOL) questionnaire on days 1, 3, and 7.
UNASSIGNED: Patients in the experimental groups A and B demonstrated markedly improved outcomes when compared with the control group. Assessments conducted on days 1, 3, and 7 demonstrated diminished levels of pain, bleeding, and swelling in both experimental groups, with experimental group B showing the least discomfort. The incorporation of XCM, either with or without stents, was associated with a reduction in analgesic consumption, underscoring its favorable influence on post-operative comfort, notwithstanding the exception of halitosis in experimental group B.
UNASSIGNED: Using XCM with or without a stent for keratinized tissue augmentation has better post-operative outcomes associated with reduced swelling, bleeding, and pain based on the QOL survey. This study provides data to support the clinical application of XCM and stents.
