目的：本初步前瞻性研究的目的是评估下颌中线单种植保留下颌全口义齿患者的临床结果、口腔健康相关生活质量（OHRQoL）和主观咀嚼能力。方法：对全口义齿患者采用下颌骨单种植体修复，复衬后植入球形附着体固位义齿。在基线和连接义齿和种植体后四周评估患者的种植结果、修复维护、主观咀嚼能力和口腔健康影响概况。结果：11例患者入组，平均观察期43.4个月（最短35个月，最长52个月）。观察期间无种植体丢失，但有4颗义齿因义齿基托中线区断裂需要修复。单中线种植下颌义齿附着后，患者的OHRQoL有明显改善。此外，种植体连接后患者的主观咀嚼能力明显提高。结论：在这项初步前瞻性临床研究的局限性内，单种植下颌覆盖义齿是一种成功的治疗选择，可以改善老年无牙患者的OHRQoL和咀嚼能力。(C) 2011 Elsevier Ltd.版权所有。
Objectives: The aim of this preliminary prospective study was to evaluate the clinical outcome, the oral health-related quality of life (OHRQoL), and the subjective chewing ability of patients with mandibular complete dentures retained by a single implant placed in the mandible midline.Methods: Patients wearing complete dentures were treated with a single implant in the mandible, followed by relining of the dentures and incorporation of ball attachments for implant retention. Implant outcome, prosthodontic maintenance, subjective chewing ability, and the oral health impact profile of the patients were assessed at baseline and at four weeks after connecting the denture and implant.Results: Eleven patients were enrolled in this investigation, and the mean observation period was 43.4 months (minimum period: 35, maximum period: 52 months). No implants were lost during observation period, but four dentures needed repair because of the fracture of the denture base in the midline area. A significant improvement was observed in the OHRQoL of the patients after the attachment of the mandibular dentures with a single midline implant. Furthermore, the subjective chewing ability of the patients was significantly improved after implant connection.Conclusions: Within the limitations of this preliminary prospective clinical study, single implant-supported mandibular overdentures were a successful treatment option for older edentulous patients who showed improvements in their OHRQoL and chewing ability.
