This report describes the outcome of maxillary implant reconstruction in 98 consecutively treated patients assigned to three groups based on the degree of maxillary atrophy as noted on radiographic examination and method of treatment. In group 1, 33 patients had 83 implants installed following sinus and/or nasal mucosal lift procedures. In group 2, 26 patients had 56 implants placed that penetrated the sinus and/or nasal cavities. The penetrating portion of the implant was covered with autogenous particulate bone harvested from the lateral aspect of the ipsilateral sinus. In group 3, 39 patients had 152 implants fixed to autogenous mandibular bone grafts placed either in the antral and/or nasal floors and/or as an onlay over the residual alveolar ridge. The age range of the patients was 15 to 76 years, with a mean of 56 years. Follow-up periods ranged from 12 to 58 months, with a mean of 26 months. Of the 291 implants installed, 19 have been lost. The importance of considering different treatment strategies when reconstructing the edentulous maxilla is discussed.
本报告描述了98例连续接受治疗的患者上颌种植体重建的结果，这些患者根据X线检查显示的上颌萎缩程度和治疗方法被分为三组。在第1组中，33例患者在进行鼻窦和/或鼻黏膜提升手术后植入了83颗种植体。在第2组中，26例患者植入了56颗穿透鼻窦和/或鼻腔的种植体。种植体的穿透部分用从同侧鼻窦外侧采集的自体颗粒骨覆盖。在第3组中，39例患者有152颗种植体固定于放置在窦底和/或鼻底和/或作为覆盖在残余牙槽嵴上的自体下颌骨移植块上。患者年龄范围为15至76岁，平均年龄为56岁。随访期为12至58个月，平均为26个月。在植入的291颗种植体中，有19颗已丢失。讨论了在无牙上颌骨重建时考虑不同治疗策略的重要性。
