目的：本研究的目的是目前的临床结果的两个酒吧夹板种植体保留下颌覆盖dovertexture.Materials和方法：在临床试验中，124例无牙患者进行了治疗，根据一个新的治疗理念，这涉及到两个酒吧夹板SLActive种植体与种植体保留下颌覆盖dovertexture的立即加载。新的传统下颌义齿用作种植体定位的模板和印模托盘，并由牙科实验室安装固位夹。在种植体被放置的同一天，传统的义齿被转换成种植体固位覆盖义齿。结果：在12-40个月的随访期内，种植体的存活率为98.8%。248个种植体中只有3个丢失。在愈合（骨整合）阶段，种植体稳定性商数显著增加（p = .0001）。在评估期间，4例患者（3%）需要重新排列的下颌覆盖义齿，而13例患者（11%）需要重新排列的上颌denture.Conclusions：两个互连的种植体可以成功地加载由下颌覆盖义齿在同一天的种植体植入的高生存率。只有少数患者需要额外的复衬覆盖义齿。重复RFA测量可用于测量种植体稳定性和存活率。
Purpose: The aim of this study was to present the clinical outcomes of the immediate loading of two bar-splinted implants retaining a mandibular overdenture.Materials and Methods: In a clinical trial, 124 edentulous patients were treated according to a new treatment concept, which involves the immediate loading of two bar-splinted SLActive implants with an implant-retained mandibular overdenture. The new conventional mandibular denture is used as a template for implant positioning and as an impression tray, and for mounting the retention clip by the dental laboratory. At the same day the implants are placed, the conventional denture is converted into an implant-retained overdenture. During the healing and evaluation period, resonance frequency analysis (RFA) was undertaken to assess the effect of loading on implant stability and survival.Results: The survival rate of the implants was 98.8% during the evaluation period (12-40 months). Only 3 of the 248 implants were lost. During the healing (osseointegration) phase, the implant-stability quotient increased significantly (p = .0001). During the evaluation period, four patients (3%) needed a relining of their mandibular overdenture, whereas 13 patients (11%) needed relining of the maxillary denture.Conclusions: Two interconnected implants can be successfully loaded by a mandibular overdenture at the same day of implant placement with a high survival rate of the implants. Only a few patients needed additional relining of the overdenture. Repeated RFA measurements can be useful in gauging implant stability and survival.
