The aim of this study is to compare and contrast the response of natural abutment teeth connected rigidly or non-rigidly to osseointegrated dental implants. Clinically significant criteria including bone loss and mobility of the teeth and implants will be used to evaluate these two treatment options, in order to subsequently aid the dentist in selecting methods of implant attachment to natural dentition. An experienced team of three Oral and Maxillofacial Surgeons, six Prosthodontists and one Periodontist will be assigned patients such that all evaluations of the teeth and implants are blinded, and not evaluated by the surgeon and prosthodontist who placed and restored the implants. In addition, the periodontist is now added to the team in order to evaluate all of the patients. A statistician has been involved with the design of this study and will participate as a co-investigator. Fifty patients will be selected based on their need for bilateral mandibular distal extension bridges articulating against a complete maxillary denture. One 10 mm. long Integral implant will be placed in the right and left mandibular first molar regions. Twelve weeks later, the implants will be restored with three unit bridges, with natural abutment teeth rigidly or non-rigidly attached to the implant evaluation. Prior to and following bridge insertion, radiographs, soft tissue pockets, bleeding and plaque indexes, tooth and implant mobility, and general clinical quality will be assessed every six months from the time of implant placement for five years. All patients will be entered into the study by the end of year three. A renewal application will be submitted to enable long term follow-up. Several NIDR consensus conference speakers requested NIH support for prospective studies on different treatment modalities for partially edentulous patients. We seek clinically significant information.

本研究的目的是比较和对比自然环境的反应 刚性或非刚性连接至骨整合牙的基牙 植入物。 具有临床意义的标准，包括骨质流失和活动能力 牙齿和种植体的数据将用于评估这两种治疗方法 选项，以便随后帮助牙医选择治疗方法 种植体附着在天然牙列上。 经验丰富的团队由三名口腔颌面外科医生、六名 将为患者分配修复科医生和一名牙周病医生，以便 所有牙齿和种植体的评估都是盲法，不进行评估 由放置和修复种植体的外科医生和口腔修复医生完成。 此外，牙周病医生现在也被添加到团队中，以便评估 所有的病人。 一位统计学家参与了设计 这项研究并将作为联合研究者参与。 将根据双侧的需要选择 50 名患者 下颌远端延伸桥与完整的关节相连 上颌义齿。 一个 10 毫米。长的整体种植体将被放置在 右下颌第一磨牙区和左下颌第一磨牙区。 十二周后， 种植体将通过三个单位桥修复，带有自然基台 牙齿刚性或非刚性地附着在种植体上的评估。 在桥插入之前和之后，X光片，软组织袋， 出血和牙菌斑指数、牙齿和种植体活动度以及一般情况 自植入之日起每六个月评估一次临床质量 安置五年。 所有患者将通过以下方式进入研究 第三年年底。 将提交续订申请以启用 长期随访。 NIDR 共识会议的几位发言人请求 NIH 支持 不同治疗方式的前瞻性研究 无牙颌患者。 我们寻求具有临床意义的信息。
