This article aims to: (1) describe the treatment of three consecutive completely edentulous patients with fixed implant-supported restorations, including simultaneous same-day immediate loading with fixed provisional restorations in both jaws; and (2) illustrate a step-by-step definitive restoration approach. All patients followed the same diagnostic protocol. One surgical intervention was performed for simultaneous implant placement in both maxilla and mandible. Following implant placement, all patients received a simultaneous, same-day, complete-arch, screw-retained provisional restoration in both jaws according to the "pickup" technique. After healing, final impressions were taken, and occlusion recorder devices were prepared on working casts. For the first occlusal record, the "half-provisionals" method was used. Definitive solid abutments were used for both laboratory and clinical procedures. After casting and finishing, the frameworks were tried in, and a new occlusal record was made. The definitive segmented restorations consisted of four fixed partial dentures in the maxilla and three in the mandible and were cemented with provisional cement. All patients received a nightguard. The pickup technique facilitated simultaneous immediate loading in both maxilla and mandible. A complete, fixed, segmented rehabilitation supported by six to eight anteroposterior implants is a reproducible treatment for completely edentulous patients when optimal anatomic conditions are present.
(1)描述连续三位全口无牙患者采用种植体支持的固定修复体的治疗情况,包括上下颌同时进行当日即刻负重并使用固定临时修复体;(2)阐述一种逐步进行的最终修复方法。所有患者均遵循相同的诊断方案。进行了一次手术干预,同时在上颌和下颌植入种植体。种植体植入后,所有患者根据“取模”技术在上下颌同时接受当日全牙弓螺丝固位的临时修复体。愈合后,制取最终印模,并在工作模型上制备咬合记录装置。对于首次咬合记录,采用“半临时修复体”方法。在实验室和临床操作中均使用定制的基台。铸造和修整完成后,试戴支架,并制作新的咬合记录。最终的分段修复体包括上颌的四个固定局部义齿和下颌的三个固定局部义齿,并用临时粘固剂粘固。所有患者均佩戴夜磨牙垫。取模技术便于上下颌同时即刻负重。当存在最佳解剖条件时,由六至八颗前后向种植体支持的完整、固定、分段式修复是全口无牙患者可重复的治疗方法。
