The purpose of this study was to record subjective patient experiences with respect to the surgical placement of dental implants and the functioning of mandibular implant-retained overdentures versus conventional dentures.
Completely edentulous patients (n = 56) unable to wear a conventional mandibular complete denture were each treated with 4 one-stage titanium plasma sprayed or Sandblasted Large-grit Acid-etched (SLA) screw implants and overdentures retained by a cast bar with extracoronal attachments. Fifty-six patients were subsequently clinically evaluated over a period of up to 6 years. Fifty-three patients responded to questions on their experiences prior to and after treatment with implant retained overdentures.
No implants or restorations failed during the observation period. Most of the patients (96%) felt satisfied with their new overdentures, and reported their new dentures fit comfortably.
The use of implants to retain and support the denture improved comfort, giving the patients more self-confidence and improved social interaction, in addition to oral rehabilitation. This study demonstrates rehabilitation of the mandibluar arch with an implant-retained overdenture is a predictable treat-
本研究的目的是记录患者关于牙种植体手术植入以及下颌种植体支持式覆盖义齿与传统义齿功能的主观体验。
无法佩戴传统下颌全口义齿的完全无牙患者（n = 56），每人接受4枚一期钛等离子喷涂或喷砂大颗粒酸蚀（SLA）螺钉种植体治疗，并使用带有冠外附着体的铸造杆固位的覆盖义齿。随后对56名患者进行了长达6年的临床评估。53名患者回答了关于种植体支持式覆盖义齿治疗前后体验的问题。
在观察期内，没有种植体或修复体失败。大多数患者（96%）对新的覆盖义齿感到满意，并报告新义齿佩戴舒适。
使用种植体固位和支持义齿除了能实现口腔功能重建外，还提高了舒适度，增强了患者的自信心并改善了社交互动。本研究表明，采用种植体支持式覆盖义齿修复下颌牙弓是一种可预期的治疗方法。
