目的：为了评估种植体支持的好处，在患者的下颌骨的双边自由终止的情况下，以确定最有利的种植体位置：前磨牙（PM）或磨牙（M）region.Methods：30名受试者与双边无界后鞍收到2 PM和2 M种植体。放置了新的RPD。3个月后提供了植入物支持。两个PM植入物支持RPD。3个月后，使用2 M种植体，反之亦然。结果指标包括口腔健康相关生活质量（OHIP-NL 49）、一般健康状况（SF-36）、视觉舒适量表（VAS）评估的满意度和佩戴RPD的小时数。在治疗前、使用新RPD发挥功能后3个月以及使用植入物支持3个月和6个月后收集数据。最后，患者表达他们的首选种植体position.Results：一般健康状况（SF-36）没有受到影响。无论种植体位置如何，OHIP-NL 49值和平均配戴时间在统计学上对ISRPD更有利。每天，ISRPD的佩戴时间比不受支持的新RPD多2-3小时。由于预期满意度和实现满意度的VAS评分未达到统计学显着水平（p > 0.05），因此满足了患者的期望。使用M种植体支持的ISRPD的VAS评分高于PM种植体支持。最后，56.7%的受试者首选M种植体支持，13.3%表示没有偏好，30%选择PM种植体support.Conclusions：下颌种植体支持有利地影响口腔健康相关的患者为基础的结果措施，在患者的双边自由结束的情况。大多数患者更喜欢种植体的支持是在molar region.Clinical significance：患者的双边自由结束的情况下，在下颌骨反对上颌义齿种植体支持其下颌可摘局部义齿受益。大多数患者更喜欢这种支持在磨牙区域。(C)2016爱思唯尔有限公司版权所有
Objectives: To assess the benefits of implant support to Removable Partial Dentures (RPD) in patients with a bilateral free-ending situation in the mandible and to determine the most favorable implant position: the premolar (PM) or the molar (M) region.Methods: Thirty subjects with a bilateral unbounded posterior saddle received 2 PM and 2 M implants. A new RPD was placed. Implant support was provided 3 months later. Two PM implants supported the RPD. After 3 months the 2 M implants were used or vice versa. Outcome measures included oral health related quality of life (OHIP-NL49), general health status (SF-36), contentment assessed on a Visual Analogue Scale (VAS) and the number of hours that the RPD was worn. Data were collected prior to treatment, 3 months after having functioned with a new RPD and after 3 and 6 months with implant support. Finally, patients expressed their preferred implant position.Results: The general health status (SF-36) was not influenced. OHIP-NL49 values and mean wearing-time were statistical significantly more favorable for ISRPD's, regardless of the implant position. Per day, the ISRPD's were worn 2-3 h more than the unsupported new RPD. Patients' expectations were met as the VAS-scores of anticipated and realized contentment did not reach a statistical significant level (p > 0.05). VAS scores for ISRPD's with M implant support were higher than for PM implant support. Finally, 56.7% of subjects preferred the M implant support, 13.3% expressed no preference and 30% opted for PM implant support.Conclusions: Mandibular implant support favorably influences oral health related patient-based outcome measures in patients with a bilateral free-ending situation. The majority of patients prefer the implant support to be in the molar region.Clinical significance: Patients with a bilateral free-ending situation in the mandible opposed by a maxillary denture benefit from implant support to their mandibular removable partial denture. Most patients prefer this support to be in the molar region. (C) 2016 Elsevier Ltd. All rights reserved.
